If tropical deforestation were a country, it would rank third in global emissions behind China and the United States. Tree cover loss is on the rise, but channeling climate mitigation finance towards forests could change the course of the world's climate.
New research assesses subnational and nonstate climate actions in the United States as part of America's Pledge.
Short-lived climate pollutants like hydrofluorocarbons, black carbon and methane aren't as well-known as carbon dioxide. But they have a powerful impact on the climate and on human health, and more countries need to develop plans to cut their emissions.
There is now widespread recognition that the poorest are at the frontline of climate change impacts. Low-income households have less capacity to adapt than those who are wealthier, and 75 percent of the extreme poor depend on activities such as agriculture that are highly sensitive to climate impacts. Unless we drastically change course, an additional 100 million people could live in extreme poverty by 2030 because of climate change,...
Governance issues and unpredictable funding are holding back the world's most important climate fund. Reform and objective criteria for replenishment can set it on the right track.
Scientists have known for years that global warming can exacerbate storms. But our understanding of the connection between hurricanes and climate change has evolved significantly in just the past year.
Scientists estimate that by managing the world's land more sustainably, such as by protecting forests and investing in reforestation, we could achieve up to 37 percent of emissions reductions necessary to limit the global rise in temperature to 2 degrees Celsius by 2030.
Talks in Bangkok, meant to set the stage for COP24, made some progress—and laid bare the many issues that negotiators must find the will to resolve for a successful 2018 COP in Katowice, Poland.
