The world is vastly underestimating the benefits of acting on climate change. Recent research from the Global Commission on the Economy and Climate finds that bold climate action could deliver at least $26 trillion in economic benefits through 2030. This ground-breaking research, produced by the Global Commission and more than 200 experts, highlights proof points of the global shift to a low-carbon economy, and identifies ways to accelerate action in five sectors: energy, cities, food and land use, water and industry. Our blog series, The $26 Trillion Opportunity, explores these economic opportunities in greater detail.
If you need motivation to skip the straw at lunch today, consider this: Scientists found that even Arctic sea ice—far removed from most major metropolitan areas—is no longer plastic-free. According to Dr. Jeremy Wilkinson of the British Antarctic Survey, "this suggests that microplastics are now ubiquitous within the surface waters of the world's ocean. Nowhere is immune."
Cape Town is running out of water. After three years of intense drought, South Africa's second-largest city is just a few months away from "Day Zero," the day when the city government will shut off water taps for most homes and businesses.

Two years after the world joined together to forge the Paris agreement on climate change, representatives from around the globe will convene in Bonn, Germany, on Nov. 6 for the next round of United Nations talks. The summit marks a critical stepping stone for global climate action.
This year's wave of climate-related natural disasters—hurricanes, floods and wildfires in developing and developing countries alike—drives home the urgency to move full speed ahead at the 23rd Conference of Parties to the UN Framework Convention on Climate Change, known informally as COP23. Increasing public and private investment in the transition to clean energy and transport, in restoring forested areas, and in more sustainable cities demonstrate that significant inroads towards tackling climate change are being made at the national and local level. Countries are also reaffirming their commitment to climate action as a priority—both at home and internationally—including support for the Paris agreement demonstrated at the G7 and G20 summits and at the African Ministerial Conference on the Environment (AMCEN).
Hansen/UMD/Google/USGS/NASA tree cover data displayed on Global Forest Watch. Green pixels represent tree cover with greater than 20 percent canopy density but do not count trees outside of these pixels. Note, coarse pixels as shown above may be more efficient for rapidly detecting large scales of deforestation, while individual mapping techniques as described below may be more effective for monitoring land restoration and degradation.

No single person could ever hope to count the world's trees. But a crowd of them just counted the world's drylands forests—and, in the process, charted forests never before mapped, cumulatively adding up to an area equivalent in size to the Amazon rainforest.
Current technology enables computers to automatically detect forest area through satellite data in order to adequately map most of the world's forests. But drylands, where trees are fewer and farther apart, stymied these modern methods. To measure the extent of forests in drylands, which make up more than 40 percent of land surface on Earth, researchers from UN Food and Agriculture Organization, World Resources Institute and several universities and organizations had to come up with unconventional techniques. Foremost among these was turning to residents, who contributed their expertise through local map-a-thons.
