Why a 2°C Target for Paris?

You're likely to hear the term 2°C a lot during the next two weeks as world leaders, scientists and policymakers meet in Paris in one of the most important climate change conferences in years. They seek to come to a binding agreement that keeps the planet from warming 2 degrees Celsius from pre-Industrial temperatures. But why that target? And what… Read More

America’s Global Plan for Warming Has Domestic Roots

America’s Global Plan for Warming Has Domestic Roots

If the U.S. gets its way in Paris, as many think is likely, then humanity will pursue a strategy for curbing global warming that would differ entirely from that of the Kyoto Protocol. The Kyoto Protocol was an unprecedented but unsuccessful 1990s climate pact that attempted to force wealthy nations to reduce emissions of climate-changing pollution … Read More

Global investment in activities to reduce planet-warming emissions and vulnerability to climate change grew 18 percent to $391 billion in 2014, as private backing for renewable energy technologies surged, researchers said. More money than ever before was channelled into action to curb climate change and its impacts, after funding leveled off in … Read More

Paris Talks Could Improve Climate Pledges

Paris Talks Could Improve Climate Pledges

Following years of failed efforts to force specific climate pollution reductions on developed countries, most nations completed unprecedented climate assignments this year, which they submitted to the U.N. They drafted climate pledges, which are known as intended nationally determined contributions, or INDCs. These INDCs describe high-level, but mo… Read More

Interactive Map Unveils the Mystery of Wind Turbines

A road trip through Iowa, Wyoming or eastern Colorado features plenty of twirling wind turbines, and they might beg a question: How much wind power can those turbines generate? And how big are those turbine blades, anyway? A new U.S. Geological Survey mapping tool, using data published Tuesday in the journal Scientific Data, lifts the veil … Read More
