4 Groundbreaking Announcements From the Global Climate Action Summit
Over the past three days, more than 4,000 people have gathered in San Francisco for the Global Climate Action Summit (GCAS) convened by California Governor Jerry Brown to mobilize regional, local and business leaders around climate change.
Seventeen states and 400 cities, representing together the world's third largest economy, have now joined Brown and summit co-chair and UN special envoy for climate action Michael Bloomberg's "We're Still In" commitment to honor the terms of the Paris agreement despite President Donald Trump's decision to withdraw, and Bloomberg announced at the summit Thursday that the group was making progress, The Nation reported.
"Today, we announce that this 'bottom up' movement will put us within striking distance of the US commitment to the Paris Agreement, even with zero support from our federal government," Bloomberg said, according to The Nation.
That announcement was based on a report written by researchers at the University of Maryland and the Rocky Mountain Institute that found that business, regional and local efforts have taken the U.S. nearly halfway towards meeting its 2025 Paris goal and will carry it two-thirds of the way by 2025 without federal support, according to a GCAS press release.
But that was only one of the many announcements made by cities, states and businesses as they celebrated their progress and reaffirmed their commitment to fighting climate change.
Here is a roundup of some of the highlights.
1. 27 Cities Have Reached Peak Carbon
Scientists have warned that global greenhouse gas emissions need to peak in 2020 and then rapidly decline in order to avoid catastrophic warming.
Luckily, on Thursday, Paris mayor and chair of the C40 network of cities committed to climate action Anne Hidalgo announced that 27 major cities, representing 54 million people, had already passed this milestone, according to a GCAS press release.
Barcelona, Basel, Berlin, Boston, Chicago, Copenhagen, Heidelberg, London, Los Angeles, Madrid, Melbourne, Milan, Montréal, New Orleans, New York City, Oslo, Paris, Philadelphia, Portland, Rome, San Francisco, Stockholm, Sydney, Toronto, Vancouver, Warsaw and Washington, DC have all seen their emissions fall over the last five years to at least 10 percent below peak levels while their economies have continued to grow.
"It is an incredible achievement for these 27 cities, including Paris, to have peaked their emissions," Hidalgo said. "As the greatest custodians of the Paris Agreement, mayors of the world's great cities have once again shown that cities are getting the job done."
2. NYC Puts Its Money Where Its Mouth Is
It is not enough for cities to rest on past accomplishments.
New York City Mayor Bill de Blasio followed up an earlier commitment to divest the New York pension fund from fossil fuels with a new commitment to double the fund's investments in climate change solutions to $4 billion within three years, a GCAS press release reported.
De Blasio was joined in his announcement by Comptroller Scott Stringer and other fund trustees.
"New York City leads from the front when it comes to the fight against climate change," de Blasio said. "We're taking a stand for generations to come with our goal to double our pension investments in job-creating climate solutions. I know that other cities will look to our example, and I implore them to join us."
3. West Coast Represents
The Pacific Coast Collaborative (PCC), representing the states of California, Oregon, Washington, the Canadian province of British Columbia and the cities of Los Angeles, Oakland San Francisco, Portland, Seattle and Vancouver, renewed its commitment to working together against climate change and towards a growing renewable energy economy.
Commitments included reducing carbon emissions, developing a low-carbon, regional transportation system, improving building efficiency and reducing food waste 50 percent by 2030.
"The West Coast represents the world's fifth largest economy and we are creating a blueprint for other regions," Washington Governor Jay Inslee said. "We are building a thriving, innovative economy that combats climate change and embraces a zero-emission future. Our efforts aren't just building a clean energy economy, they're also creating great places to live. Our communities are growing healthier and more prosperous, and attractive to new businesses and workers."
4. EV Innovators Charge Forward
The company announced a pledge to add 2.5 million charging points to its network within the next seven years on Friday, according to a press release emailed to EcoWatch.
The commitment represents a nearly fifty-fold expansion of its charging network, would prevent two million tons of greenhouse gas emissions from entering the atmosphere and would help establish infrastructure for a future in which EVs are expected to represent more than 50 percent of new car purchases by 2040.
ChargePoint President and CEO Pasquale Romano said in a press conference that the company had done the math, and the commitment meant the company was "going to grow in line with the adoption rate of EVS."
The commitment actually only covers a "subset" of ChargePoint's business, Romano said.
ChargePoint has developed a business model of going from business to business and installing chargers in company parking lots, and this is the network it is committed to expanding.
Its home and transportation fleet charging efforts are not included and will represent additional greenhouse gas savings.
Romano said that policy decisions by individual governments, such as Trump's reversal of Obama-era fuel efficiency standards, could be "speed bumps" in the growth of EVs, but policies already established in California and the EU, as well as the quality and falling price of EVs, meant that their use would continue to expand.
"In the long term, this is an unstoppable train," he said.

Farms with just one or a handful of different crops encourage fewer species of pollinating and pest-controlling insects to linger, ultimately winnowing away crop yields, according to a new study.
Up to half of the detrimental impacts of the "landscape simplification" that monocropping entails come as a result of a diminished mix of ecosystem service-providing insects, a team of scientists reported Oct. 16 in the journal Science Advances.

"Our study shows that biodiversity is essential to ensure the provision of ecosystem services and to maintain a high and stable agricultural production," Matteo Dainese, the study's lead author and a biologist at Eurac Research in Bolzano, Italy, said in a statement.
It stands to reason that, with declines in the sheer numbers of insects that ferry pollen from plant to plant and keep crop-eating pests under control, these services will wane as well. But until now, it hasn't been clear how monocultures affect the number and mix of these species or how crop yields might change as a result.
Aiming to solve these questions, Dainese and his colleagues pulled together data from 89 studies cutting across a variety of landscapes, from the tropics of Asia and Africa to the higher latitudes of northern Europe. They tabulated the number of pollinating and pest-controlling insects at these sites — both the absolute number of individuals and the number of species — along with an assessment of the ecosystem services the insects provided.
In almost all of the studies they looked at, the team found that a more diverse pool of these species translated into more pollination and greater pest control. They also showed that simplified landscapes supported fewer species of service-providing insects, which ultimately led to lower crop yields.
The researchers also looked at a third measure of the makeup of insect populations — what they called "evenness." In natural ecosystems, a handful of dominant species with many more individuals typically live alongside a higher number of rarer species. The team found as landscapes became less diverse, dominant species numbers dwindled and rare species gained ground. This resulting, more equitable mix led to less pollination (though it didn't end up affecting pest control).
"Our study provides strong empirical support for the potential benefits of new pathways to sustainable agriculture that aim to reconcile the protection of biodiversity and the production of food for increasing human populations," Ingolf Steffan-Dewenter, one of the study's authors and an animal ecologist at the University of Würzburg in Germany, said in the statement.
The scientists figure that the richness of pollinator species explains around a third of the harmful impacts of less diverse landscapes, while the richness of pest-controlling species accounts for about half of the same measure. In their view, the results of their research point to the need to protect biodiversity on and around crops in an uncertain future.
"Under future conditions with ongoing global change and more frequent extreme climate events, the value of farmland biodiversity ensuring resilience against environmental disturbances will become even more important," Steffan-Dewenter said.

Greenland had quite the summer. It rose from peaceful obscurity to global headliner as ice melted so swiftly and massively that many were left grasping for adjectives. Then, Greenland's profile was further boosted, albeit not to its delight, when President Trump expressed interest in buying it, only to be summarily dismissed by the Danish prime minister.
During that time I happened to be in East Greenland, both as an observer of the stark effects of climate change and as a witness to local dialogue about presidential real estate aspirations, polar bear migrations and Greenland's sudden emergence as a trending topic.

Creepy-crawlies are among the oldest life forms on this planet. Before dinosaurs ever walked the earth, insects were certainly already there. Some estimates date their origins to 400 million years ago. They're also extremely successful. Of the 7 to 8 million species documented on Earth, around three quarters are likely bugs.
But several insect species could disappear for good in the next few decades and that would have serious consequences for humans.
