Despite Major Melt, Arctic Sea Ice Will Miss Record Low

Despite Major Melt, Arctic Sea Ice Will Miss Record Low

As the sun begins its seasonal descent in the Arctic sky and temperatures drop, the summer melt of sea ice is slowing down. In the next few weeks, the span of the Arctic Ocean covered by ice will reach its annual low. But despite beginning the summer at unprecedentedly low levels, this year’s minimum won’t break the stunning record of 2012, expert… Read More

167 Tiny Maps Tell the Major Story of Climate Change

167 Tiny Maps Tell the Major Story of Climate Change

Climate change just got another telling visual courtesy of the famed temperature spiral creator. But rather than a graph, it’s a series of 167 maps. Alone, they each tell the story of whether a year was mostly hot or mostly cold or mostly average for the planet. Together, they show unequivocally how much our planet has warmed since the 1850s … Read More

Natural Gas Emissions to Surpass Those of Coal in 2016

Natural Gas Emissions to Surpass Those of Coal in 2016

The U.S. is expected to reach a major carbon emissions milestone this year: For the first time, carbon dioxide emissions from burning natural gas for electricity in the U.S. are set to surpass those from burning coal — the globe’s chief climate polluter. Emissions from burning natural gas are expected to be 10 percent greater than those from coal … 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

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

This Is What the Ice-Free Northwest Passage Looks Like

This Is What the Ice-Free Northwest Passage Looks Like

An ice-free Northwest Passage was once the stuff of legend. But it’s now becoming the norm thanks to global warming, and commercial freighters to luxury cruise ships are racing to turn a profit off the newest frontier on earth. An image published by NASA Earth Observatory shows a nearly ice-free path from the North Atlantic to the Pacific… Read More

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

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

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
