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.
These movements enjoy mass popularity, but how effective are they? Greta Thunberg proclaimed that "pretty much nothing [had] been done" since staging school strikes to raise awareness of the climate crisis in 2018, while Micah White, co-creator of Occupy Wall Street, has said that social change as we know it is dead.
As the world now faces the deepest economic downturn since the Great Depression, there will be greater social unrest and calls for a new set of solutions.
Youth movements will need to find a more mature form of activism to counter the popularized puritanism that has prevailed. More precisely, here are 4 considerations for young changemakers as they seek a more just and equitable world:
1. Learn From the Past
Young people tend to be comfortable with change. Their instant adoption of technology is an example. However, they may lack an understanding of the more permanent realities – requiring patience and stoicism.
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 said, "We can educate our youth a lot better. We're not delving deeper into social justice movements from the past."
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.
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.
In fact, King spent his final year mired in public disapproval with over 75% of Americans considering him "irrelevant" including 60% of African Americans.
By studying the legacy of previous efforts, BLM has managed to rally approximately 75% of the American public; a feat that will undeniably ensure the longevity of its cause.
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 indigenous elders that have fought for climate justice before its inception and ultimately signal the nuance and maturity that would activate allies within systems of power.
2. Become Part of Systems Change
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.
Unsurprisingly, this often leads to problematic and incomplete solutions. Take, for example, an app for African farmers developed by students who have neither farmed nor been to Africa.
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 Map the System competition to celebrate some of the most promising youth-led mappings and the World Economic Forum's Global Shapers Community convenes more than 7,000 young people under the age of 30 to address local, regional and global challenges.
To achieve systemic change, young changemakers must first unpack systems into three components; elements, interconnections and functions:
- Elements are essentially the key stakeholders in the system. This can include individuals, land or objects.
- Interconnections are the laws and social norms that bind the elements together.
- Functions are the end-goals.
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.
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.
Today, young changemakers can rely on online resources like Systems-Led-Leadership to analyze any given system of inequality and then direct their unique skills and knowledge towards the most effective intervention.
3. Avoid Heropreneurship
Daniela Papi-Thornton first coined the term heropreneurship to describe a growing trend that credits social change to the "founder" of an organization or movement exclusively.
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.
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.
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.
4. Know Your Place
In 2016, a political action committee entitled Can You Not emerged with the aim of discouraging white men from running for office in minority districts.
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?
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?
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.
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.

A More Targeted, Effective Kind of Activism
Social media has played its critical part in providing young people with a vehicle to advocate for social reform.
Whether it's Greta Thunberg's speech during the United Nations General Assembly in 2019 or Emma Gonzalez rallying crowds for more stringent gun control. younger voices are swaying public opinion and pressuring political systems to operate more inclusively.
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.
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.
Finally, it is pivotal that they invest in a support system and seek to dissolve personal anxieties that may compromise their change-making potential.
It's time for youth activism to grow up.

These longer periods of stratification could have "far-reaching implications" for lake ecosystems, the paper says, and can drive toxic algal blooms, fish die-offs and increased methane emissions.
The study, published in Nature Communications, finds that the average seasonal lake stratification period in the northern hemisphere could last almost two weeks longer by the end of the century, even under a low emission scenario. It finds that stratification could last over a month longer if emissions are extremely high.
If stratification periods continue to lengthen, "we can expect catastrophic changes to some lake ecosystems, which may have irreversible impacts on ecological communities," the lead author of the study tells Carbon Brief.
The study also finds that larger lakes will see more notable changes. For example, the North American Great Lakes, which house "irreplaceable biodiversity" and represent some of the world's largest freshwater ecosystems, are already experiencing "rapid changes" in their stratification periods, according to the study.
'Fatal Consequences'
As temperatures rise in the spring, many lakes begin the process of "stratification." Warm air heats the surface of the lake, heating the top layer of water, which separates out from the cooler layers of water beneath.
The stratified layers do not mix easily and the greater the temperature difference between the layers, the less mixing there is. Lakes generally stratify between spring and autumn, when hot weather maintains the temperature gradient between warm surface water and colder water deeper down.
Dr Richard Woolway from the European Space Agency is the lead author of the paper, which finds that climate change is driving stratification to begin earlier and end later. He tells Carbon Brief that the impacts of stratification are "widespread and extensive," and that longer periods of stratification could have "irreversible impacts" on ecosystems.
For example, Dr Dominic Vachon – a postdoctoral fellow from the Climate Impacts Research Centre at Umea University, who was not involved in the study – explains that stratification can create a "physical barrier" that makes it harder for dissolved gases and particles to move between the layers of water.
This can prevent the oxygen from the surface of the water from sinking deeper into the lake and can lead to "deoxygenation" in the depths of the water, where oxygen levels are lower and respiration becomes more difficult.
Oxygen depletion can have "fatal consequences for living organisms," according to Dr Bertram Boehrer, a researcher at the Helmholtz Centre for Environmental Research, who was not involved in the study.
Lead author Woolway tells Carbon Brief that the decrease in oxygen levels at deeper depths traps fish in the warmer surface waters:
"Fish often migrate to deeper waters during the summer to escape warmer conditions at the surface – for example during a lake heatwave. A decrease in oxygen at depth will mean that fish will have no thermal refuge, as they often can't survive when oxygen concentrations are too low."
This can be very harmful for lake life and can even increase "fish die-off events" the study notes.
However, the impacts of stratification are not limited to fish. The study notes that a shift to earlier stratification in spring can also encourage communities of phytoplankton – a type of algae – to grow sooner, and can put them out of sync with the species that rely on them for food. This is called a "trophic mismatch."
Prof Catherine O'Reilly, a professor of geography, geology and the environment at Illinois State University, who was not involved in the study, adds that longer stratified periods could also "increase the likelihood of harmful algae blooms."
The impact of climate change on lakes also extends beyond ecosystems. Low oxygen levels in lakes can enhance the production of methane, which is "produced in and emitted from lakes at globally significant rates," according to the study.
Woolway explains that higher levels of warming could therefore create a positive climate feedback in lakes, where rising temperatures mean larger planet-warming emissions:
"Low oxygen levels at depth also promotes methane production in lake sediments, which can then be released to the surface either via bubbles or by diffusion, resulting in a positive feedback to climate change."
Onset and Breakup
In the study, the authors determine historical changes in lake stratification periods using long-term observational data from some of the "best-monitored lakes in the world" and daily simulations from a collection of lake models.
They also run simulations of future changes in lake stratification period under three different emission scenarios, to determine how the process could change in the future. The study focuses on lakes in the northern hemisphere.
The figure below shows the average change in lake stratification days between 1900 and 2099, compared to the 1970-1999 average. The plot shows historical measurements (black), and the low emission RCP2.6 (blue), mid emissions RCP6.0 (yellow) and extremely high emissions RCP8.5 (red) scenarios.

The plot shows that the average lake stratification period has already lengthened. However, the study adds that some lakes are seeing more significant impacts than others.
For example, Blelham Tarn – the most well-monitored lake in the English Lake District – is now stratifying 24 days earlier and maintaining its stratification for an extra 18 days compared to its 1963-1972 averages, the study finds. Woolway tells Carbon Brief that as a result, the lake is already showing signs of oxygen depletion.
Climate change is increasing average stratification duration in lakes, the findings show, by moving the onset of stratification earlier and pushing the stratification "breakup" later. The table below shows projected changes in the onset, breakup and overall length of lake stratification under different emission scenarios, compared to a 1970-1999 baseline.
The table shows that even under the low emission scenario, the lake stratification period is expected to be 13 days longer by the end of the century. However, in the extremely high emissions scenario, it could be 33 days longer.
The table also shows that stratification onset has changed more significantly than stratification breakup. The reasons why are revealed by looking at the drivers of stratification more closely.
Warmer Weather and Weaker Winds
The timing of stratification onset and breakup in lakes is driven by two main factors – temperature and wind speed.
The impact of temperature on lake stratification is based on the fact that warm water is less dense than cool water, Woolway tells Carbon Brief:
"Warming of the water's surface by increasing air temperature causes the density of water to decrease and likewise results in distinct thermal layers within a lake to form – cooler, denser water settles to the bottom of the lake, while warmer, lighter water forms a layer on top."
This means that, as climate change causes temperatures to rise, lakes will begin to stratify earlier and remain stratified for longer. Lakes in higher altitudes are also likely to see greater changes in stratification, Woolway tells Carbon Brief, because "the prolonging of summer is very apparent in high latitude regions."
The figure below shows the expected increase in stratification duration from lakes in the northern hemisphere under the low (left), mid (center), and high (right) emission scenarios. Deeper colors indicate a larger increase in stratification period.

The figure shows that the expected impact of climate change on stratification duration becomes more pronounced at more northerly high latitudes.
The second factor is wind speed, Woolway explains:
"Wind speed also affects the timing of stratification onset and breakdown, with stronger winds acting to mix the water column, thus acting against the stratifying effect of increasing air temperature."
According to the study, wind speed is expected to decrease slightly as the planet warms. The authors note that the expected changes in near-surface wind speed are "relatively minor" compared to the likely temperature increase, but they add that it may still cause "substantial" changes in stratification.
The study finds that air temperature is the most important factor behind when a lake will begin to stratify. However, when looking at stratification breakup, it finds that wind speed is a more important driver.
Meanwhile, Vachon says that wind speeds also have implications for methane emissions from lakes. He notes that stratification prevents the methane produced on the bottom of the lake from rising and that, when the stratification period ends, methane is allowed to rise to the surface. However, according to Vachon, the speed of stratification breakup will affect how much methane is released into the atmosphere:
"My work has suggested that the amount of accumulated methane in bottom waters that will be finally emitted is related to how quickly the stratification break-up occurs. For example, a slow and progressive stratification break-up will most likely allow water oxygenation and allow the bacteria to oxidise methane into carbon dioxide. However, a stratification break-up that occurs rapidly – for example after storm events with high wind speed – will allow the accumulated methane to be emitted to the atmosphere more efficiently."
Finally, the study finds that large lakes take longer to stratify in spring and typically remain stratified for longer in the autumn – due to their higher volume of water. For example, the authors highlight the North American Great Lakes, which house "irreplaceable biodiversity" and represent some of the world's largest freshwater ecosystems.
These lakes have been stratifying 3.5 days earlier every decade since 1980, the authors find, and their stratification onset can vary by up to 48 days between some extreme years.
O'Reilly tells Carbon Brief that "it's clear that these changes will be moving lakes into uncharted territory" and adds that the paper "provides a framework for thinking about how much lakes will change under future climate scenarios."

Currently the U.S. Supreme Court has on its docket a case between Texas, New Mexico and Colorado and another one between Mississippi and Tennessee. The court has already ruled this term on cases pitting Texas against New Mexico and Florida against Georgia.
Climate stresses are raising the stakes. Rising temperatures require farmers to use more water to grow the same amount of crops. Prolonged and severe droughts decrease available supplies. Wildfires are burning hotter and lasting longer. Fires bake the soil, reducing forests' ability to hold water, increasing evaporation from barren land and compromising water supplies.
As a longtime observer of interstate water negotiations, I see a basic problem: In some cases, more water rights exist on paper than as wet water – even before factoring in shortages caused by climate change and other stresses. In my view, states should put at least as much effort into reducing water use as they do into litigation, because there are no guaranteed winners in water lawsuits.

Dry Times in the West
The situation is most urgent in California and the Southwest, which currently face "extreme or exceptional" drought conditions. California's reservoirs are half-empty at the end of the rainy season. The Sierra snowpack sits at 60% of normal. In March 2021, federal and state agencies that oversee California's Central Valley Project and State Water Project – regional water systems that each cover hundreds of miles – issued "remarkably bleak warnings" about cutbacks to farmers' water allocations.
The Colorado River Basin is mired in a drought that began in 2000. Experts disagree as to how long it could last. What's certain is that the "Law of the River" – the body of rules, regulations and laws governing the Colorado River – has allocated more water to the states than the river reliably provides.
The 1922 Colorado River Compact allocated 7.5 million acre-feet (one acre-foot is roughly 325,000 gallons) to California, Nevada and Arizona, and another 7.5 million acre-feet to Utah, Wyoming, Colorado and New Mexico. A treaty with Mexico secured that country 1.5 million acre-feet, for a total of 16.5 million acre-feet. However, estimates based on tree ring analysis have determined that the actual yearly flow of the river over the last 1,200 years is roughly 14.6 million acre-feet.
The inevitable train wreck has not yet happened, for two reasons. First, Lakes Mead and Powell – the two largest reservoirs on the Colorado – can hold a combined 56 million acre-feet, roughly four times the river's annual flow.
But diversions and increased evaporation due to drought are reducing water levels in the reservoirs. As of Dec. 16, 2020, both lakes were less than half full.
Second, the Upper Basin states – Utah, Wyoming, Colorado and New Mexico – have never used their full allotment. Now, however, they want to use more water. Wyoming has several new dams on the drawing board. So does Colorado, which is also planning a new diversion from the headwaters of the Colorado River to Denver and other cities on the Rocky Mountains' east slope.

Utah Stakes a Claim
The most controversial proposal comes from one of the nation's fastest-growing areas: St. George, Utah, home to approximately 90,000 residents and lots of golf courses. St. George has very high water consumption rates and very low water prices. The city is proposing to augment its water supply with a 140-mile pipeline from Lake Powell, which would carry 86,000 acre-feet per year.
Truth be told, that's not a lot of water, and it would not exceed Utah's unused allocation from the Colorado River. But the six other Colorado River Basin states have protested as though St. George were asking for their firstborn child.
In a joint letter dated Sept. 8, 2020, the other states implored the Interior Department to refrain from issuing a final environmental review of the pipeline until all seven states could "reach consensus regarding legal and operational concerns." The letter explicitly threatened a high "probability of multi-year litigation."
Utah blinked. Having earlier insisted on an expedited pipeline review, the state asked federal officials on Sept. 24, 2020 to delay a decision. But Utah has not given up: In March 2021, Gov. Spencer Cox signed a bill creating a Colorado River Authority of Utah, armed with a $9 million legal defense fund, to protect Utah's share of Colorado River water. One observer predicted "huge, huge litigation."
How huge could it be? In 1930, Arizona sued California in an epic battle that did not end until 2006. Arizona prevailed by finally securing a fixed allocation from the water apportioned to California, Nevada and Arizona.
Litigation or Conservation
Before Utah takes the precipitous step of appealing to the Supreme Court under the court's original jurisdiction over disputes between states, it might explore other solutions. Water conservation and reuse make obvious sense in St. George, where per-person water consumption is among the nation's highest.
St. George could emulate its neighbor, Las Vegas, which has paid residents up to $3 per square foot to rip out lawns and replace them with native desert landscaping. In April 2021 Las Vegas went further, asking the Nevada Legislature to outlaw ornamental grass.
The Southern Nevada Water Authority estimates that the Las Vegas metropolitan area has eight square miles of "nonfunctional turf" – grass that no one ever walks on except the person who cuts it. Removing it would reduce the region's water consumption by 15%.
Water rights litigation is fraught with uncertainty. Just ask Florida, which thought it had a strong case that Georgia's water diversions from the Apalachicola-Chattahoochee-Flint River Basin were harming its oyster fishery downstream.
That case extended over 20 years before the U.S. Supreme Court ended the final chapter in April 2021. The court used a procedural rule that places the burden on plaintiffs to provide "clear and convincing evidence." Florida failed to convince the court, and walked away with nothing.
