A Mississippi-Sized Area of Forest Disappeared in 2015

A Mississippi-Sized Area of Forest Disappeared in 2015

A Mississippi-sized chunk of the world’s forests was decimated in 2015 because of wildfire, logging and expanding palm oil plantations, according to a new study. The loss is part of a continuing trend of deforestation that could have devastating implications for the climate. About 49 million acres of forest disappeared worldwide in 2015, mainly in… Read More

Heat Makes It Too Hot for Africa’s Wild Dogs to Hunt

Heat Makes It Too Hot for Africa’s Wild Dogs to Hunt

Rising temperatures are making it too hot for African wild dogs to hunt and the number of their pups that survive is plummeting, according to a new study. The research is among the first to show a direct impact of increased heat on wildlife that appears well adapted to high temperatures. There are only 7,000 African wild dogs left in the wild and… Read More

At Midway Point, 2017 Is 2nd-Hottest Year on Record

At the halfway point of the year, 2017 remains the second-hottest year to date — a surprise given the demise of the El Niño that helped boost temperatures to record levels last year. The continued near-record warmth is a marker of just how much global temperatures have risen thanks to the greenhouse gases accumulating in the atmosphere from fossil… Read More

Countries With Coral Reefs Must Do More on Climate

Countries With Coral Reefs Must Do More on Climate

Countries with responsibility over world heritage-listed coral reefs should adopt ambitious climate change targets, aiming to cut greenhouse gas emissions to levels that would keep global temperature increases to just 1.5°C, the UN agency responsible for overseeing world heritage sites has said. At a meeting of Unesco’s world heritage committee in… Read More

Today’s Extreme Heat May Become Norm Within a Decade

Today’s Extreme Heat May Become Norm Within a Decade

When 2015 blew the record for hottest year out of the water, it made headlines around the world. But a heat record that was so remarkable only two years ago will be just another year by 2040 at the latest, and possibly as early as 2020, regardless of whether the greenhouse gas emissions warming the planet are curtailed. That is the conclusion of a… Read More

Greenhouse Gases Are Rapidly Changing the Atmosphere

Greenhouse Gases Are Rapidly Changing the Atmosphere

Humanity’s grand experiment in the atmosphere continues, and a new report documents just how far it’s gone. On Tuesday, the National Oceanic and Atmospheric Administration released its annual index of 20 key greenhouse gases. It shows that their direct influence on the climate has risen 140 percent since 1750, with 40 percent of that rise coming… Read More

Rising Temps Could Bring Flight Delays Worldwide

Rising Temps Could Bring Flight Delays Worldwide

Imagine boarding a summertime flight at LaGuardia Airport in New York City, only to be told that the airline needs a dozen or so passengers to take a later flight because it’s too hot outside for the plane to take off fully loaded. That could become a common scenario at 19 major airports worldwide as extreme heat caused by global warming disrupts … Read More

This Map Shows Warming’s Fingerprints on Weather

This Map Shows Warming’s Fingerprints on Weather

The field of climate science that looks for the fingerprints of climate change on extreme weather events has been growing rapidly in recent years, making it hard to keep track of the dozens of studies that have been done. A new interactive map put together by Carbon Brief, a UK-based data journalism site, makes that task easier. It rounds up the… Read More
