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

Study Suggests Earlier Onset of Human-Driven Warming

Study Suggests Earlier Onset of Human-Driven Warming

To fully understand the warming of the planet that is being driven by human emissions of greenhouse gases, scientists need to examine the history of climate changes on Earth. Hampering this effort is the fact that direct measurements of temperature and other climate data only go back to about the late 19th century. But by using records kept by the… Read More

In Streak of Extreme Storms, What’s the Role of Warming?

The staggering rains that swamped some 60,000 houses in southern Louisiana and shattered the previous state rain record are the latest — and perhaps most remarkable — in a string of jaw-dropping rain events across the U.S. over the past year. From South Carolina to Houston to West Virginia and Ellicott City, Md., each instance of extreme rainfall a… Read More

After Scorching Heat, Earth Likely to Get Respite in 2017

The Earth is likely to get relief in 2017 from record scorching temperatures that bolstered governments' resolve last year in reaching a deal to combat climate change, scientists said on Wednesday. July was the hottest single month since records began in the 19th century, driven by greenhouse gases and an El Niño event warming the Pacific. And… Read More

With Warming, Western Fires May Sicken More People

With Warming, Western Fires May Sicken More People

Shrouded by smoke from a fire in California’s parched San Bernardino Mountains, schools in the Victor Valley closed their doors last week. The Pilot Fire was contained on Monday — shortly before the Blue Cut Fire broke out, billowing soot and ash over the valley afresh, forcing further closures. “This is a pretty unprecedented situation,” said … Read More

Alaskan Village Votes to Relocate Due to Climate Change

Alaskan Village Votes to Relocate Due to Climate Change

A Native American village in Alaska has voted to relocate its entire population of some 600 people due to the threat of rising seas, officials said on Thursday. Shishmaref, located on a tiny island north of the Bering Strait that separates the United States and Russia, is losing up to 10 feet of shoreline each year, according to … Read More

Biomass Power Slumps as EPA, Industry Spar on Science

Biomass Power Slumps as EPA, Industry Spar on Science

With the biomass power industry in financial tumult, its leaders are pinning hopes for revival on Congress’s potential willingness to interfere with climate science. The legislative language, introduced by some Republicans in the House and Senate and by a Democrat-aligned independent Senator, varies slightly. But it all requires that most wood… Read More

Stagnant Air on the Rise, Upping Ozone Risk

Stagnant Air on the Rise, Upping Ozone Risk

Summers in the U.S. bring more than just searing, dangerously hot days. When the air is stagnant and there is little air circulation, hot weather can trigger high levels of air pollution that can have health consequences for millions of Americans. With stagnant air now occurring more frequently in much of the country, and projected to continue incr… Read More
