Between a record-strong El Niño and catastrophic floods, fires and drought, 2016 was a memorable year for weather and climate in North America as well as globally. What can we expect as we roll into 2017? A precise weather forecast is asking too much, but there is already a lot we can say about some key factors. Here are six developments to watch for in 2017. They're presented in rough order of increasing confidence, followed by details on each prediction.
1. Better Odds of El Niño Than La Niña, but a Neutral Pacific Still Favored
The biggest single driver of year-to-year atmospheric variations around the globe is the El Niño–Southern Oscillation (ENSO), including El Niño and its counterpart, La Niña. A year ago, it was virtually certain that the record-strong El Niño of 2015-16 would continue through at least the first few months of 2016, as it indeed did. This time around, the ENSO signal is far less clear-cut. Sea surface temperatures (SSTs) in the benchmark Niño 3.4 region of the eastern tropical Pacific have been inconclusive in recent months, hovering close to the La Niña threshold (at least -0.5 C below the seasonal average) since late July.

It's now become less likely that the ocean and atmosphere will commit to a well-defined La Niña event for early 2017. There's almost no telling what will happen later in the year, on the other side of the infamous "spring predictability barrier" that often separates one El Niño or La Niña event from another. One clue we do have is the unusual persistence this year of a belt of warmer-than-average SSTs from the central tropical Pacific to the west coast of North America. This warm phase of what's called the Pacific Meridional Mode may herald a new El Niño event in 2017-18, as niftily explained by Dan Vimont (University of Wisconsin Center for Climatic Research) in a recent climate.gov post.
In their joint probabilistic outlook issued in early December, NOAA's Climate Prediction Center (CPC) and the International Research Institute for Climate and Society (IRI) called for decreasing odds of La Niña over the next few months, dropping to just 18 percent by late spring. Neutral conditions are deemed most likely by CPC/IRI, with 65 percent odds by spring and 53 percent by summer. And the odds of El Niño are expected to steadily rise throughout the first half of 2017, reaching 29 percent by summer. Strong El Niño events like the one we just had are usually followed by a significant La Niña event. If the atmosphere instead ends up cueing El Niño for 2017-18, it would reinforce the notion that we've entered a positive phase of the Pacific Decadal Oscillation—a sign that we might expect more El Niño than La Niña events for as long as a decade or two.

2. Wide Range of Possibilities for Atlantic Hurricane Action
The well-predicted demise of the 2015-16 El Niño boosted confidence in 2016's largely successful seasonal hurricane outlooks for the Atlantic, where wind shear was down from 2015 and sea-surface temperatures saw a spike atop their long-term warming trend. (See our roundup post from Dec. 27 on global tropical cyclones in 2016 and their connections to climate change.) Because ENSO is one of the biggest shapers of Atlantic hurricane seasons, our current uncertainty about next year's ENSO state means we can't say much yet about whether the 2017 Atlantic tropical season will be hectic, sedate or somewhere in between.
Forecasters at Colorado State University no longer issue formal seasonal hurricane outlooks as early as December, but CSU's Dr. Phil Klotzbach laid out his thoughts for us last week in a qualitative discussion. Along with monitoring ENSO, Klotzbach also keeps close tabs on the Atlantic Multidecadal Oscillation and Atlantic thermohaline circulation, which are cyclic natural variations in SST, surface air pressure, and oceanic flow across the North Atlantic. When the AMO is positive (warm) and the THC is strong, the Atlantic pumps out more hurricanes over periods that can range from 25 to 35 years. At other times, unusually cold waters prevail in the far North Atlantic, typically a sign of a slowdown of the THC and a ramp-down in Atlantic hurricane action.

With cold waters widespread across the far north Atlantic in 2014 and 2015, Klotzbach hypothesized in a 2015 Science article that the active Atlantic period that began in 1995 may have already drawn to a close. Now he's not so sure. "I was generally thinking we had moved into a cold AMO, but we haven't yet seen the re-emergence of the cold anomalies in the far North Atlantic like we have the past couple of winters (at least not yet!)," Klotzbach told me in an email. For this analysis, Klotzbach typically uses SSTs across a box roughly bounded by 50 N-60 N latitude and 10 W-50 W longitude. Figure 3 shows that only part of this area currently has below-average SSTs. "We're just now moving into the height of winter, though, so we may still see some reemergence and anomalous cooling in the far North Atlantic this winter," said Klotzbach. "I decided to hedge with the outlook so far, and hopefully we'll have a better idea of what is coming up by the time the April forecast rolls around." Here are the five possibilities (with odds) put forth by Klotzbach in his December update:
40 percent chance: AMO/THC is above average and no El Niño occurs (resulting in a seasonal average Accumulated Cyclone Energy (ACE) activity of ~ 130).
20 percent chance: AMO/THC becomes very strong in 2017 and no El Niño occurs (ACE ~ 170).
20 percent chance: AMO/THC is below average and no El Niño occurs (ACE ~ 80).
10 percent chance: AMO/THC is above average and El Niño occurs (ACE ~ 80).
10 percent chance: AMO/THC is below average and El Niño develops (ACE ~ 50).
3. More Tornadoes and Tornado Deaths in 2017 Than 2016? Probably So
It's been a blessedly quiet year for U.S. tornadoes, climatologically speaking. According to Patrick Marsh (NOAA Storm Prediction Center), the year 2016 delivered a preliminary total of 1060 tornado reports through Dec. 28, with few or none expected through the rest of the year. This may sound like a very high total, but the number of final tornado reports typically drops from the preliminary total by about 15 percent after duplicate reports have been weeded out. The annual number drops even further relative to prior years when it's adjusted for "inflation" against earlier decades, when fewer people were watching and reporting every twister. Using a linear trend adjustment, Marsh estimates that the final, inflation-adjusted tornado total for 2016 will be around 888, which would be the lowest for any year going back to at least 1954 assuming that the database is normalized (inflation-adjusted) through 2015. "Four of the last five years—2016, 2014, 2013 and 2012—have been the quietest years on record when report inflation is accounted for," said Marsh.
This year did produce a few dramatic outbreaks during peak tornado season, but these played out mostly in open country, where few structures were damaged and few people were hurt. The deadliest events of 2016 were "off-season": seven people died in a Southeast and East Coast tornado outbreak on Feb. 23-24--the nation's second-largest February outbreak on record--and five deaths occurred across the South during an overnight outbreak on Nov. 29-30.
All told, tornadoes have killed only 17 people in the U.S. in 2016, well below the average toll of 46 per year over the three prior years. Assuming we make it to Dec. 31 without any additional tornado deaths, which looks almost certain, we'll have been graced with the least-deadly U.S. year for twisters since 1986, when only 15 people were killed. In data going back to 1875 provided by Harold Brooks (National Severe Storms Laboratory), the only other year with fewer than 20 deaths was 1910, with just 12 fatalities.
Figure 5. During El Niño events (top), the frequency of U.S. tornadoes typically drops. When a La Niña phase prevails (bottom), tornado frequency goes up (indicated by red areas). The effect is strongest in the boxed area.Nature Geoscience 2015, courtesy IRI
The strong El Niño of 2015-16 likely helped tamp down tornado activity this year, at least in the heart of Tornado Alley. Researchers at IRI/Columbia University have shown that the most active spring seasons for tornado and hail over the central U.S., especially the Southern Plains, are linked to strong La Niña events, while the very quietest seasons are related to strong El Niño events. In January 2015, the researchers, led by John Allen (now at Central Michigan University), called for better-than-even odds (54 percent) of a below-average number of tornadoes this year, as opposed to the 33/33/33 percent split (below, above, and near average) one would otherwise expect. (See more details at this conference presentation).
As with Atlantic hurricanes, even a mostly quiet season can still produce deadly mayhem if one destructive event, such as a major landfalling hurricane or a family of violent tornadoes, happens to hit the wrong place at the wrong time. "It's an ongoing challenge to think about how to convey this information," Allen told me. "I think it's also worth noting that we still don't have a lot of other climate signals for improving our forecasts when we don't have ENSO-driven predictability." It's thus hard to tell how tornado counts will evolve in 2017, since the ENSO signal is so weak. However, given the very low activity this year, there's a good chance that we will see more twisters prowling the nation in 2017 than we did in 2016.

4. A Very Warm Year Globally, but Likely Short of a Record
Barring a major, sun-blocking volcanic eruption, we can expect 2017 to continue the long-term warming trend of the last few decades attributed to human-produced greenhouse gases. However, 2017 is unlikely to continue the string of global record highs set in 2014, 2015, and (virtually certainly) 2016. The record-strong El Niño of 2015-16, which sent vast amounts of heat from ocean to atmosphere, played a key role in pushing temperatures just enough above the long-term warming trend to set new global highs. Now that this major El Niño is gone, it's no surprise that global atmospheric heat is already subsiding a bit relative to seasonal norms—though it would be a huge mistake to interpret this totally expected dip as any sign that longer-term warming has gone away.
On Dec. 20, the UK Met Office released its official outlook for 2017 (see Figure 6). The agency projects that global temperature will end up between 0.63 and 0.87 C (1.45 – 1.89 F) above the 1961-1990 average of 14.0 C (57.2 F). "This forecast, which uses the new Met Office supercomputer, adds weight to our earlier prediction that 2017 will be very warm globally but is unlikely to exceed 2015 and 2016: the two warmest years on record since 1850," said Adam Scaife, head of long-range prediction at the Met Office. According to research fellow Chris Folland: "2016 was well forecast as the methods used detected the warming influence of the strong El Niño. However, last year's El Niño only accounts for around 0.2 C of the global mean temperature rise for 2016, when compared with the long-term average between 1961 and 1990. Increasing greenhouse gases are the main cause of warming since pre-industrial times."

5. Another New Peak in Global Carbon Dioxide
Sadly, our highest-confidence forecast for the atmosphere is that carbon dioxide concentrations will continue their relentless upward march. The burning of fossil fuels continues to release more than 35 billion metric tons of CO2, an invisible greenhouse gas, every year. (That's about 10,300 pounds for every person on Earth). Just over half of that total is absorbed by plants, soil and the sea each year. The rest stays in the atmosphere, much of it destined to stay there for many hundreds and even thousands of years.
CO2 values measured atop Mauna Loa Observatory in Hawaii are once again rising toward the usual spring peak after hitting their annual low in late September of around 401 parts per million. Because most of Earth's plant life is north of the equator, atmospheric CO2 drops with the growth of CO2-absorbing vegetation in late northern spring and summer, and it increases again each winter and spring as vegetation dies off. We can expect daily and weekly CO2 values in spring 2017 to soar above 410 ppm for the first time in human history, and it's even possible the monthly average will hit that mark as well.
The final weekly value below 400 ppm that we'll see in our lives is virtually certain to be the 399.86 ppm value recorded in late August 2015 during the approach of Hurricane Madeline. As that hurricane approached Hawaii from the east, its circulation is believed to have imported slightly lower-CO2 air from north of Hawaii.

6. Slam-Dunk Forecast: A Spectacular Total Eclipse in August
We can say with rock-solid confidence that a large swath of the U.S. will be treated to one of the most widely viewable total solar eclipses in U.S. history (if the weather cooperates!) on Aug. 21. The band of totality—the region where the sun will be completely obscured by the moon for as long as 2 minutes and 40 seconds—will extend from northern Oregon across the central Plains and mid-South to South Carolina (see Figure 8). Millions of Americans will be within an hour or two's drive of the totality band, and untold numbers of people from across the world are heading to the States for the big show. The timing of totality will range from about 10 a.m. PDT on the West Coast to around 2:45 p.m. EDT on the East Coast. This means that the mid-August sun will be quite high in the sky for the eclipse, enhancing the potential drama.
NASA has a plethora of great material on the upcoming eclipse, including an excellent "Eclipse 101" page with crucial safety tips (for example, never look at an uneclipsed or partially eclipsed sun without specially designed glasses that meet international standards for eclipse viewing). Obviously, there's no telling what the weather will be doing on Aug. 21, but the perfectly named Eclipseophile website has state-by-state breakdowns of where climatology leans toward the best views. As one might expect, the highest odds of cloud-free skies and dry air are toward the western U.S.

The 2008 financial crisis spurred a number of youth movements including Occupy Wall Street and the Arab Spring. A decade later, this anger resurfaced in a new wave of global protests, from Hong Kong to Beirut to London, only this time driven by the children of the 2008 financial crisis.
1. Learn From the Past<p>Young people tend to be comfortable with change. Their instant adoption of technology is an example.<a target="_blank"> However, they may lack an understanding of the more permanent realities – requiring patience and </a>stoicism.</p><p>This wisdom is typically in the hands of individuals who either work within systems or who have accumulated far more tenure. This was effectively echoed by 13-year old activist, Naomi Wadler who <a href="https://www.youtube.com/watch?v=17Aa6XLZe9A" target="_blank">said</a>, "We can educate our youth a lot better. We're not delving deeper into social justice movements from the past."</p><p>Youth movements that are informed by the success and pitfalls of prior efforts offer a more promising outcome. Take for example, the Black Lives Matter (BLM) movement, co-founded by a 32-year old Alicia Garza.<span></span></p><p>Unlike the civil rights movement of the 1960's, BLM lacks central governance. This means that opponents can't attack its leadership as a means to discredit the whole movement. In the 1960's, this is exactly what happened to the civil rights movement, when critics went after Martin Luther King, stalling the collective efforts of the movement.</p><p>In fact, King spent his final year <a href="https://eu.usatoday.com/story/opinion/2018/04/04/martin-luther-king-jr-50-years-assassination-donald-trump-disapproval-column/482242002/" target="_blank">mired in public disapproval</a> with over 75% of Americans considering him "irrelevant" including 60% of African Americans.</p><p>By studying the legacy of previous efforts, BLM has managed to rally approximately <a href="https://www.washingtonpost.com/politics/big-majorities-support-protests-over-floyd-killing-and-say-police-need-to-change-poll-finds/2020/06/08/6742d52c-a9b9-11ea-9063-e69bd6520940_story.html" target="_blank">75% of the American public</a>; a feat that will undeniably ensure the longevity of its cause.</p><p>For the youth climate movement, it too must reconcile the long record of activism that predates its tenure. It ought to model itself as an intergenerational movement by giving greater credence to the activists, environmental scientists and <a href="https://www.weforum.org/agenda/2020/05/juan-manuel-santos-colombia-indigenous-peoples-coronavirus-pandemic-climate-change-environment-nature/" target="_blank">indigenous elders</a> that have fought for climate justice before its inception and ultimately signal the nuance and maturity that would activate allies within systems of power.</p>
2. Become Part of Systems Change<p>From the college campus to the coworking space, you would be hard pressed to avoid the sight of a social impact competition that invites young people to resolve some of the world's most intractable problems.<br></p><p>Unsurprisingly, this often leads to problematic and incomplete solutions. Take, for example, <a href="https://ssir.org/articles/entry/tackling_heropreneurship" target="_blank">an app for African farmers</a> developed by students who have neither farmed nor been to Africa.<br></p><p>Fortunately, there is a growing shift towards empowering young people to better diagnose the systems that uphold inequality. For example, Oxford University hosts the annual <a href="http://www.oxfordglobalchallenge.com/" target="_blank">Map the System</a> competition to celebrate some of the most promising youth-led mappings and the World Economic Forum's <a href="https://www.globalshapers.org/story" target="_blank">Global Shapers Community</a> convenes more than 7,000 young people under the age of 30 to address local, regional and global challenges.</p><p>To achieve systemic change, young changemakers must first unpack systems into <a href="https://wtf.tw/ref/meadows.pdf" target="_blank">three components</a>; elements, interconnections and functions:</p><ul><li>Elements are essentially the key stakeholders in the system. This can include individuals, land or objects.</li><li>Interconnections are the laws and social norms that bind the elements together.</li><li>Functions are the end-goals.</li></ul><p>Take for example, the persistence of sexual harassment in the workplace as a systems issue. The elements in the system would include the victim, perpetrator and other intermediary bodies including line managers and human resource teams. The interconnections could include forced arbitration laws that prohibit employees from seeking public courts and a managerial culture that protects high performing perpetrators and pressures victims into silence. In which case, the ultimate functions (or rather dysfunctions) of the system discourage victims from pursuing action and enable perpetrators and enablers to enjoy the benefits of career progression without due trial.</p><p>Systemic change is about redesigning the interconnections (the cultural norms and laws). In the example above, it involves challenging the use of private arbitrary courts and uprooting a toxic work culture. Reclaiming this intuition opens a pandora's box that ultimately allows for any given system to operate more inclusively.<br></p><p>Today, young changemakers can rely on online resources like <a href="http://systems-ledleadership.com/" target="_blank">Systems-Led-Leadership</a> to analyze any given system of inequality and then direct their unique skills and knowledge towards the most effective intervention.</p>
3. Avoid Heropreneurship<p>Daniela Papi-Thornton first coined the term <a href="http://tacklingheropreneurship.com/" target="_blank">heropreneurship</a> to describe a growing trend that credits social change to the "founder" of an organization or movement exclusively.</p><p>This culture has inspired an entire generation of young change-makers who are swayed by the allure of the "heroic" founder and whose behaviors are validated through youth awards, grants and speaking circuits that glorify a role in the limelight. This pervasive culture undercuts the entire spectrum of actors that really creates social change.</p><p>Social change does not necessarily warrant the creation of a new organization or movement. Change-makers should consider the root causes that perpetuate and uphold inequalities and then map the existing players and solutions. This process might point to scaling up the work of an existing organization or helping a local candidate run for office.<br><br>For young people who wish to create social change, their efforts – while extremely important – may go unnoticed. This is an expectation that needs to be managed.<br></p>
4. Know Your Place<p>In 2016, a political action committee entitled <a href="http://canyounot.org/" target="_blank">Can You Not</a> emerged with the aim of discouraging white men from running for office in minority districts.</p><p>Despite the comical graphics, the campaign highlights an important question for young changemakers, particularly if they advocate for issues that they have not lived: in the quest for social change, can the actions of change-makers unwittingly perpetuate injustices, even as they seek to end them?<br></p><p>In the example above, could the notion of a white man effectively assuming the role of a translator between minority communities and government only reinforce their structural underrepresentation in political decision-making? Could the desire to assume office without lived experience also signal little faith in the leadership of the very communities being served?<br></p><p>A more effective approach to social change may be to encourage such actors to take stock of the unintended consequences of misrepresentation. In doing so, they may come to appreciate the importance of "stepping back" to allow others to "step forward." More concretely, this could result in building trusted relationships with the community and eventually empowering more local voices to consider public leadership.<br></p><p>For young changemakers, it is pivotal that they assess their own standing in a given system and avoid perpetuating the very inequalities they wish to tackle.</p>

A More Targeted, Effective Kind of Activism<p>Social media has played its critical part in providing young people with a vehicle to advocate for social reform.</p><p>Whether it's <a href="https://www.theguardian.com/environment/2019/sep/23/greta-thunberg-speech-un-2019-address" target="_blank">Greta Thunberg's speech</a> during the United Nations General Assembly in 2019 or <a href="https://variety.com/2018/politics/features/emma-gonzalez-parkland-interview-1202972485/" target="_blank">Emma Gonzalez</a> rallying crowds for more stringent gun control. younger voices are swaying public opinion and pressuring political systems to operate more inclusively.<br></p><p>The impact of these extraordinary young people is inspiring, but arguably they struggle to provide a course of action for the average young person who is motivated to pursue social change. The inconvenient truth is that social reform is difficult and even more so for a young person who wrestles with challenges related to experience and credibility.<br></p><p>To be more effective, young changemakers must forge greater bonds with late-stage activists as well as potential allies within systems of power. They must also understand the systems that uphold equality and pinpoint the intervention that would most likely inspire systemic change.<br></p><p>Finally, it is pivotal that they invest in a support system and seek to dissolve <a href="https://www.weforum.org/agenda/2020/06/this-is-how-wellbeing-drives-social-change-and-why-cultural-leaders-need-to-talk-about-it" target="_blank">personal anxieties</a> that may compromise their change-making potential.</p><p>It's time for youth activism to grow up.</p>

For 20 years, the Colima fir tree (Abies colimensis) has been at the heart of many disputes to conserve the temperate forests of southern Jalisco, a state in central Mexico. Today, the future of this tree rests upon whether the area's avocado crops will advance further and whether neighboring communities will unite to protect it.
The Nevado de Colima volcano stands 4,260 meters (13,976 feet) above sea level. Agustín del Castillo<p>According to biologist José Villa Castillo, the director of Nevado de Colima National Park and Nevado de Colima Cloud Forest State Park, it is imperative to stop the commercialization of the tree's timber and to create policies that conserve the forests in which it lives. Villa Castillo also supported the inclusion of the tree on the endangered species list.</p><p>Villa Castillo acknowledged the enormous challenge of conserving this tree, and he said the pressure to exploit its timber without sustainable management is far from the only problem. The expansion of the nearby avocado industry also threatens its survival.</p><p>When allowed to grow, the Colima fir tree can become monumental: It can reach 60 meters (196 feet) in height and 2 m (6.5 ft) in diameter. To protect this giant, specialists and communities often promote ecotourism and conservation projects inside the national and state parks that surround the Nevado de Colima volcano.</p>
Fires That Clear Land for Avocado Crops<p>In 2012, a group of researchers from the University of Guadalajara proposed to the Secretariat of Environment and Natural Resources (SEMARNAT) the recognition of the <em>A. colimensis</em> as a unique species to differentiate it from the sacred fir (<em>A. religiosa</em>), which is the dominant fir tree in the Trans-Mexican Volcanic Belt, a collection of volcanoes in central Mexico.</p><p>The Colima fir tree "has extremely low genetic diversity; it has the lowest known genetic diversity among all the species in the Abies genus in Mesoamerica and one of the lowest among all the species of trees on the planet," according to the authors of the proposal to recognize the tree as an endangered species. The area it occupies "is very limited": just 15,002 hectares (37,071 acres), or 0.007% of the territory of Mexico.</p><p>The Nevado de Colima volcano, which stands 4,260 meters (13,976 feet) above sea level, is one of only eight peaks that exceed 4,000 m (13,123 ft) in Mexico. It is only 40 kilometers (25 miles) from the Pacific Ocean and is considered an "evolutionary island" because the ecosystems in its high-altitude areas drive unique adaptations in species and are cut off from other ecosystems by hundreds of kilometers. The Colima fir tree is an example of the area's biological differentiation, according to Libertad Arredondo, a researcher and expert on the ecology of high mountains.</p>
The fir forests are mainly located in the middle of slopes or in ravines. Agustín del Castillo<p>Even though the tree has remained on that "evolutionary island," its situation has become increasingly complicated by the impact of deforestation, which was propelled by the issuance of permits for forest exploitation. Fires, started to convert the land to agriculture or other uses, also present a threat to the ecosystem, according to the experts who suggested the tree should be considered endangered.</p><p>The researchers said the tree's future prospects are further complicated by its slow growth rate, its high degree of genetic erosion, the effects of climate change, and the movement of clouds to higher altitudes. The position of clouds is crucial because they act as an essential source of moisture for fir trees.</p><p>Villa Castillo, an expert in pine genetics and reproduction, said the Colima fir tree has never been successfully reproduced in nurseries, which would likely make it impossible to conduct reforestation efforts to help repopulate the species.</p><p>The forests that contain the Colima fir tree are in cold, humid climates, with very little light reaching the understory, and they're mainly located in the middle of slopes or in ravines. The species thrives when surrounded by oak trees, coniferous trees and other types of vegetation common in mountainous cloud forests. The tree also requires a primary habitat with little disturbance from humans.</p><p>According to Villa Castillo, fire kills most Colima fir tree seedlings, as it kills seedlings of other species in the <em>Abies</em> genus. In recent years, more fires have been started in the forest to clear the way for avocado trees.</p>
A tree and other vegetation in the cloud forest surrounding the Nevado de Colima volcano. Agustín del Castillo<p>Sonia Navarro Pérez, a researcher from the University of Guadalajara who has monitored and conducted biological inventories in the area, has seen firsthand how the growth of the avocado industry has led to the loss of important forested areas.</p><p>She described the case of the indigenous community of San José del Carmen, which is in the municipality of Zapotitlán de Vadillo, near one of the patches of forest.</p><p>"We were working with them to establish productive alternatives that are good for nature," Navarro Pérez said. "But when the avocado came, it overwhelmed us completely."</p><p>Since 2013, the coniferous forests around the Nevado de Colima volcano have lost nearly 6,600 hectares (16,300 acres) due to illegal logging, livestock rearing and intentionally set fires, according to Mexico's deforestation risk index developed by the <a href="https://www.gob.mx/inecc" target="_blank">National Institute of Ecology and Climate Change</a>.</p>

Agustín del Castillo<p>"[What was once] an original area of 7,000 hectares [17,300 acres] of fir-specific forest is now cut in half," said Villa Castillo, the director of the Nevado de Colima national and state parks.</p><p>The expansion of the avocado crops is the most recent threat in a series of events that have negatively impacted the conservation of the forests in the area.</p><p>Between the 1940s and the 1990s, the Atenquique Industrial Company had exclusive rights to use the timber from these forests under a concession from the Mexican government. The result was "that the forests were skimmed — that is, they took the best parts," Villa Castillo said.</p><p>When the concession expired in 1995, the forests did not experience a transition to a sustainable timber extraction method. Those who, along with landowners who held small plots, had rights to the shared land were limited to selling the forested areas, at very low prices, to the new logging industries located in Ciudad Guzmán. "Then, there were many abuses against the communities. The money was given to the caciques" — families who have always controlled the shared land — "alms were left for the community, and our forests were very poorly managed," said Rafael González Merín, the former president of Huescalapa, a collective of communally owned farmland known as an <em>ejido</em>.</p><p>As a result, many residents of the community believe the solution is to conserve the forests with productive projects.</p>
Communities Pitch in to Save Their Trees<p>Unlike the communities that have been overtaken by the avocado industry, Huescalapa has largely managed to resist its arrival. The community of shared land, which spans more than 1,200 hectares (3,000 acres), is home to pine and fir trees within its shady temperate forests.</p><p>The residents of Huescalapa have also set aside the proposals they've received from the forestry industry, which has expressed interest in buying their trees.</p><p>According to Gerardo Bernabé Aguayo, logging activity in this area of Jalisco "has been very negative because the industry has managed delicate areas — with very limited species — poorly, so we are supporting and launching projects with the communities." Bernabé Aguayo is the president of the board of trustees of Nevado de Colima and Adjacent Basins, a civil association created about 20 years ago after being promoted by the government of the state of Jalisco. To support the conservation of the national and state parks, the board has financing from the regional private sector.</p><p>The board manages about 6 million pesos ($268,000) contributed by the federal government in 2020. With resources from the private sector, it has been able to access an additional 1.5 million pesos ($67,000).</p>
An area of fir trees that has been destroyed by logging. Agustín del Castillo<p>Rodrigo Cantera Hernández, the president of the El Alcázar Ecotourism Center, said that in Huescalapa, the caciques removed timber from the fir forests, "but they did not report any money to the other community members, so we fought to eject them and were able to do so a couple of years ago."</p><p>In Huescalapa, three main conflicts over timber have taken place in the past 20 years. First, in 1999, a group of community members sold part of the forest to a forestry industry from Ciudad Guzmán. A movement led by citizens put an end to the logging five months later.</p><p>Next, in 2012, environmental authorities granted permission for forest exploitation in these areas, so fir trees continued to be cut down. An opinion by the <a href="https://www.ideaac.org.mx/" target="_blank">Institute of Environmental Law</a>, a civil society organization, cited scientific evidence that demonstrated the uniqueness of mountain fir trees and forced SEMARNAT to withdraw these permissions.</p>
The citizens of Huescalapa formed a cooperative to launch the El Alcázar Ecotourism Center. El Alcázar Ecotourism Center<p>Then, in 2015, a federal judge suspended a new authorization to exploit timber in the cloud forest.</p><p>For communities like Huescalapa to have economic options that do not involve the use of timber because of the detrimental effects that this may have on the remaining population of Colima fir trees, ecotourism and similar activities are promoted.</p><p>According to Bernabé Aguayo, the goal is for the natural forest to be conserved as "a key area for contemplation, enjoyment, the preservation of environmental services, and research."</p><p>In 2019, the cooperative in El Alcázar received 1 million pesos ($44,600), which allowed it to have the basic infrastructure for the ecotourism center. The cooperative may receive an additional 3 million pesos ($133,800) in 2020 to purchase more equipment and improve the roads, but support for this funding was blocked in a community assembly. "They have not understood that it is for the benefit of everyone, that it is not money for our pockets," said Cantera Hernández, the president of the cooperative.</p><p>In Huescalapa, one of the challenges that interferes with efforts to promote the ecotourism center is the division that exists between community members. Many seek to use the timber, but others are already convinced of the importance of conservation.</p><p>Villa Castillo, the director of the Nevado de Colima national and state parks, emphasized that projects similar to the El Alcázar Ecotourism Center are being promoted in San José del Carmen and Zapotitlán de Vadillo, which are very close to the border between the states of Jalisco and Colima.</p>
María de la Luz Cortés Reyes, the leader of the Amixtlán cooperative, which was created in San José del Carmen. Agustín del Castillo<p>The Amixtlán Ecotourism Center is located in the community of San José del Carmen. A cluster of cabins marks the entrance to the cloud forest, designated a state park since 2009.</p><p>"We decided to protect our forest long before they declared the state park, 20 years before then," said María de la Luz Cortés Reyes, a community leader in San José del Carmen. She recalled that when loggers came with offers to buy the forest, members of the community believed that they offered very little payment and that "the damage [that the loggers left] was too much." For that reason, they decided "not to touch the forest, because it produces water for the crops and for our houses."</p><p>Cortés Reyes said the community was able to construct the ecotourism center because it had resources managed by the Nevado de Colima Cloud Forest State Park and by the Board of Trustees of Nevado de Colima and Adjacent Basins. However, she said it is important that more promotion is given to the area and that urgent problems, such as those with the water supply system, are resolved.</p>

Agustín del Castillo<p>In the community of Zapotitlán de Vadillo, citizens also promoted the Puerta de la Hacienda Ecotourism Center, where administrators support the biocultural production of mezcal, an alcoholic beverage made from agave. The drink is made by two <em>mezcaleros</em>, or people who are experts in creating mezcal: Marcario Partida from Zapotitlán de Vadillo, and Rosario Pineda from Tetapán, a small community in Zapotitlán de Vadillo.</p><p>Other productive projects that are promoted in the communities include the organic production of eggs, such as by Efigenia Larios, a small producer from the community of El Tecuán. Additionally, the shared land communities of Zapotitlán de Vadillo, San José del Carmen and Huescalapa are provided with equipment for fire prevention and materials to help restore the forest soil.</p><p>Artists have painted murals that shine a spotlight on forest conservation in San José del Carmen and Zapotitlán de Vadillo.</p><p>The intention of these efforts is to allow those who own land or have rights on this fragile mountain to "understand that there are other options besides logging, and that they, too, can generate development," said Arredondo, the researcher who specializes in the ecology of high mountains.</p><p>Despite the strong pressure for land use changes brought by the avocado agroindustry and fostered by the high level of impunity that often prevails in rural areas, many of the area's landowners continue to search for a model in which their forests can remain standing.</p><p>"Many neighbors say that we are foolish for not wanting to sell this beautiful forest that we have, but that money only lasts for a short time," said José Avalo Lino, a farmer in San José del Carmen. "We are so certain of [the importance of] preventing logging that, long before the declaration of the natural protected area, our community assembly had already decided to save this forest. We will continue to be 'foolish' in this decision."</p>

This summer's high street fashions have more in common than styles and colors. From the pink puff-sleeved dream going for just €19.99 ($22.52) at H&M, to Zara's elegant €12.95 ($14.63) halter-neck dress, clothing stores are alive with cheap organic cotton.
"Sustainable" collections with aspirational own-brand names like C&A's "Wear the change," Zara's "join life" or H&M's "CONSCIOUS" are offering cheap fashion and a clean environmental conscience. Such, at least, is the message. But is it really that simple?
Going Green, or Just Greenwashing?<p>"Fashion brands are capitalizing on the fact that consumers are interested in buying fairly and ecologically produced items," said Katrin Wenz, an expert in agriculture at Friends of the Earth Germany (BUND). "Organic cotton is certainly a step in the right direction, because neither <a href="https://www.dw.com/en/patents-on-plants-is-the-sellout-of-genes-a-threat-to-farmers-and-global-food-security/a-49906072" target="_blank">genetic modification</a> nor synthetic pesticides can be used in its production. But these own-brand sustainability labels rarely tell us anything about what happens later on in the production chain."</p><p>Viola Wohlgemuth, a textiles expert at Greenpeace, says companies create their sustainability labels and criteria themselves. "Sustainability is not a protected or specific term, which leaves the door wide open for so-called greenwashing," she told DW.</p>
Independent Certifications Trustworthier<p>Both experts emphasize that independent environmental certifications offer a better indicator of a product's eco credentials, including labor conditions for workers involved in production. Examples include the Global Organic Textile Standard label (GOTS) and the IVN Best certification, which is awarded by the International Association of Natural Textile Industry (IVN).</p><p>Heike Hess, head of IVN's Berlin branch, says using organic cotton alone "is not enough to make fashion really sustainable," and that producing clothes involves a more involved production chain. After being grown in the fields, cotton fibers have to be separated from their seeds, spun, dyed, printed and sewn to create finished items of clothing.</p><p>"Ecological and social standards are important at every stage of production," Hess said. "That includes minimizing the use of harmful chemicals, managing water usage and waste, limiting CO2 emissions and ensuring human rights, fair wages, protections for workers and much more. Only then can fashion really be called sustainable."</p><p>And that comes at a price. <a href="https://www.dw.com/en/heres-why-your-next-t-shirt-should-be-made-of-organic-cotton/a-39083921" target="_blank">Organic cotton</a> summer dresses certified with the GOTS label usually cost somewhere between €60-100 (about $67-113). </p>
Water Polluted and Wasted<p>Textile production often uses harmful chemicals, especially during the wet processing stage when threads are formed, dyed and woven, says Wohlgemuth. According to the UN Environment Program, around 20% of global wastewater is generated during textile dyeing and processing. Communities and ecosystems in <a href="https://www.dw.com/en/bangladeshs-textile-industry-works-towards-becoming-more-eco-friendly/a-50983898" target="_blank">textile producing countries across Asia</a> are worst affected.</p><p>Since launching its <a href="https://www.greenpeace.org/international/act/detox/" target="_blank">'Detox My Fashion'</a> campaign in 2011, Greenpeace has secured commitments from some 80 global companies in the fashion industry to eliminate hazardous chemicals by the end of this year.</p><p>But that alone doesn't imply sustainability. Growing cotton also requires a huge amount of water and vast areas of land, says Sabine Ferenschild from the Südwind Institute for Economics and Ecumenism in Bonn.</p><p>"Organic cotton is only sustainable when grown in rainy regions such as India, and planted in combination with food crops rather than in competition with them," she said. "But we have seen that cotton farming is increasingly being shifted to desert regions. That can never be sustainable."</p>
Eco Collections Remain a Market Niche<p>Ferenschild is critical of major fashion brands' attempts to go green with their own criteria and labeling for certain products, while the majority of what they're selling is still produced conventionally.</p><p>Germany is pursuing a new approach to green certification with its government-backed <a href="https://www.bmz.de/en/issues/textilwirtschaft/gruener_knopf/index.html" target="_blank">'Green Button' label</a>. A company can only use the label if all its products comply with high environmental and labor standards. These standards are not as strict as those demanded by organic certifiers, but experts say the 'Green Button' label is a step in the right direction, as it prevents producers offloading responsibility to subcontractors in the production chain.</p>
An 'Eco' Dress for €20 ($22.60): Too Good to Be True?<p>According to the Bremen Cotton Exchange, organic cotton costs between 10 and 50% more than conventional cotton. Premium fibers boost prices the most; the raw material is not necessarily the most important factor in terms of cost.</p><p>Global fashion brands like H&M are able to keep their prices down, even for the products in their "sustainable" ranges, due to the huge volume of items they produce, textiles expert Ferenschild told DW.</p><p>H&M uses its own "CONSCIOUS" label for products which contain "at least 50 percent sustainable materials, such as organic cotton and recycled polyester." It is not clear to consumers what percentage of organic cotton is used in the items labeled as such. In response to DW's request for clarification, H&M wrote: "Across our entire range, H&M uses 16 percent organic cotton according to our most recent figures."</p><p>According to the Bremen Cotton Exchange, just 0.7 percent of the global cotton harvest in the 2017/18 season was organic.</p><p><strong>The Real Problem Is One of Quantity</strong></p><p>Even if the big fashion brands wanted to move further towards truly sustainable production, current consumption habits would make that almost impossible. The real problem is that far too many clothes are being produced. According to a 2015 Greenpeace study, there are more than five billion items of clothing in German wardrobes alone. </p>
