Eat Those Turkey Leftovers, Reduce Greenhouse Gases

Eat Those Turkey Leftovers, Reduce Greenhouse Gases

In the days after feasting on Thanksgiving dinner, Americans will be throwing away millions of tons of leftovers, and that waste comes with a potentially unappreciated environmental cost: emissions of potent greenhouse gases. Food disposed of in landfills slowly rots and releases methane, a greenhouse gas 25 times more powerful than carbon dioxide… Read More

States May Drive U.S. Climate Policy Under Trump

States May Drive U.S. Climate Policy Under Trump

Donald Trump could scrap the Obama administration’s plans to combat climate change once he takes office, a move that could shift climate policy making to local lawmakers instead of national ones, experts say. Throughout his campaign, Trump made his vision for federal climate policy clear: He has promised to reverse Obama’s climate agenda … Read More

Oil, Gas and Cows Culprits in Methane Spike, Study Says

Oil, Gas and Cows Culprits in Methane Spike, Study Says

When trying to figure out why atmospheric concentrations of methane — a potent greenhouse gas driving climate change — have been rising continuously since 2007, fingers often point to North America’s shale oil and gas boom over the last decade. But a National Oceanic and Atmospheric Administration study published Thursday in the journal Nature … Read More

Obama Just Tied Climate Change to National Security

Obama Just Tied Climate Change to National Security

On Wednesday, President Obama took another step toward securing his climate legacy. This time his focus wasn’t on energy, public lands or international diplomacy. It was on national security and making sure the U.S. military is prepared for a more unstable future. The White House published a presidential memorandum setting up a timetable for more … Read More

Study Finds Biofuels Worse for Climate than Gasoline

Study Finds Biofuels Worse for Climate than Gasoline

Years of number crunching that had seemed to corroborate the climate benefits of American biofuels were starkly challenged in a science journal on Thursday, with a team of scientists using a new approach to conclude that the climate would be better off without them. Based largely on comparisons of tailpipe pollution and crop growth linked to biofu… Read More

Climate Pollution Can Complicate Fishes’ Sex Lives

Climate Pollution Can Complicate Fishes’ Sex Lives

The mating rituals of male ocellated wrasses are as intricate as their shimmering scales, and new research showing that carbon dioxide pollution can affect those rituals has some scientists fretting for the future of fish. Elevated levels of carbon dioxide — which dissolves from the atmosphere into oceans, where it changes acidity levels — can … Read More

Local Efforts to Save Coral Reefs May Be Futile

Local Efforts to Save Coral Reefs May Be Futile

Scientists agree that coral reefs will continue to be decimated if climate-changing pollution from fossil fuels, farming and deforestation is not addressed. They disagree, however, over whether local efforts to restrict fishing and reduce water pollution will make meaningful differences in a world of fast-rising temperatures.… Read More

Global Climate Spending Focusing on Forest Protection

Global Climate Spending Focusing on Forest Protection

Forests straddling the equator are critical to a stable climate because they store vast amounts of carbon, and a new study finds that the U.S. and four other developed countries are spending billions of dollars to keep those forests intact. An analysis of how the U.S., Japan, Germany, France and Norway have donated money to climate change … Read More
