Greenhouse Gases From Reservoirs Fuel Climate Change

Greenhouse Gases From Reservoirs Fuel Climate Change

Hydropower reservoirs are considered to be major sources of low-carbon electricity that can be used to cut greenhouse gas emissions to combat climate change. But those same reservoirs emit global warming gases, and a team of researchers has now tallied just how much those gases impact the climate. Globally, reservoirs are responsible for about 1.3… Read More

Appeals Court Mulls Challenge to Clean Power Plan

Six hours and 42 minutes.

The Biggest Loser in Last Night’s Debate? Climate Change

Monday’s presidential debate featured spirited back-and-forths on tax returns, how to heal divides in the U.S. and the candidates’ economic plans.

The World Passes 400 PPM Threshold. Permanently

The World Passes 400 PPM Threshold. Permanently

In the centuries to come, history books will likely look back on September 2016 as a major milestone for the world’s climate. At a time when atmospheric carbon dioxide is usually at its minimum, the monthly value failed to drop below 400 parts per million.

What 2 Million Years of Temps Say About the Future

What 2 Million Years of Temps Say About the Future

That the climate has changed before is a given. So is the reality that humans are changing it now by dumping carbon pollution in the atmosphere. The deep history of temperature changes can inform us about what comes next for our fair planet and new research published Monday in Nature provides a continuous 2-million-year record of the past. It … Read More

America’s Climate Plan Falls Short of its Promises

America’s Climate Plan Falls Short of its Promises

The federal government will need to ramp up its fight against climate pollution if it wants to keep a key promise under a United Nations pact, new research from the Lawrence Berkeley National Laboratory shows. The U.S. pledged during United Nations meetings in France last year to reduce its greenhouse gas pollution by a little more than a quarter … Read More

Terns Flee Warming Temps in Epic Migration to Alaska

Terns Flee Warming Temps in Epic Migration to Alaska

Eyebrows would be raised if American crocodiles, found on the southern tip of Florida, decided to relocate to New York’s Fifth Avenue or Moroccan camels suddenly joined the tourist throng outside Buckingham Palace in London. Yet this is the scale of species shift that appears to be under way in Alaska. In July, researchers in Cape Krusenstern… Read More
