If you want to build a fire, you need three things: Ignition, fuel and oxygen. But wildfire in California is a much more complex people-stoked witch’s brew. The state burns regularly because of fierce autumn winds, invasive grasses that act as kindling, fire-happy native shrubs and trees, frequent...

According to a study released on Thursday, Aug. 20, 2020, Greenland lost a record amount of ice during an extra warm 2019, with the melt massive enough to cover California in more than four feet (1.25 meters) of water.

Greenland lost a record amount of ice during an extra warm 2019, with the melt massive enough to cover California in more than four feet (1.25 meters) of water, a new study said. After two years when summer ice melt had been minimal, last summer shattered all records with 586 billion tons (532...

California sizzled to a triple-digit temperature so hot that meteorologists need to verify it as a planet-wide high mark. Death Valley recorded a scorching 130 degrees (54.4 degrees Celsius) Sunday, which if the sensors and other conditions check out, would be the hottest Earth has been in more...

This July 2015 photo taken by University of Ottawa glaciology professor Luke Copland shows Canadian Ice Service ice analyst Adrienne White taking a photo of cracks of the Milne Ice Shelf, which just broke apart. The Milne ice shelf was on of the Arctic's few remaining intact ice shelves, but at the end of July 2020 about 43% broke off. Scientists say that without a doubt it's man-made global warming.

Much of Canada's remaining intact ice shelf has broken apart into hulking iceberg islands thanks to a hot summer and global warming, scientists said. Canada's 4,000-year-old Milne Ice Shelf on the northwestern edge of Ellesmere Island had been the country's last intact ice shelf until the end of...

The U.N. weather agency is warning that average temperatures in Siberia came in 10 degrees Celsius (18 Fahrenheit) above average last month, a spate of exceptional heat that has fanned devastating fires in the Arctic Circle. The high heat has also contributed to the rapid depletion of ice sea coverage off the Russian Arctic coast. World Meteorological Organization Secretary-General Petteri Taalas said the Arctic is heating more than twice as fast as the global average. WMO says the extended heat is linked to a large “blocking pressure system” and northward swing of the jet stream. (Russian Emergency Ministry Press Service via AP, File)

Rich Americans produce nearly 25% more heat-trapping gases than poorer people at home, according to a comprehensive study of U.S. residential carbon footprints. Scientists studied 93 million housing units in the nation to analyze how much greenhouse gases are being spewed in different locations and...
