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.

Canada's last intact ice shelf collapses due to warming

Aug. 7, 2020 3:38 PM EDT

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 July when ice...

Lake Tahoe's fluctuating clarity took a dive last year, worsening by about 8 feet during an especially cold and wet winter as sedimentation, algae growth and a tiny invasive shrimp continue to pose restoration challenges.

Lake Tahoe's fluctuating clarity worsens amid wet winter

Jul. 31, 2020 4:32 PM EDT

RENO, Nev. (AP) — Lake Tahoe’s fluctuating clarity got worse last year during an especially cold and wet winter as sedimentation, algae growth and a tiny invasive shrimp continued to pose restoration challenges for the famed clear water of the mountain lake straddling the California-Nevada line.

A bumblebee flies near a lavender bush in the International Peace Gardens in Salt Lake City, Utah, on Friday, July 17, 2020. A federal review of existing data unveils an alarming trend for the western bumblebee population, which has seen its numbers dwindle by as much as 93% in the last two decades. The Deseret News reports the find by the U.S. Geological Survey will help inform a species status assessment to begin this fall by the U.S. Fish and Wildlife Service, which may ultimately add the insect to its endangered species list.(Kristin Murphy/The Deseret News via AP)

Dramatic decline found in Western bumblebee populations

SALT LAKE CITY (AP) — A federal review of existing data unveils an alarming trend for the western bumblebee population, which has seen its numbers dwindle by as much as 93% in the last two decades.

FILE - In this Friday, July 10, 2020 file grab taken from video provided by Russian Emergency Ministry, shows a Russian Emergency Ministry's Beriev plane BE-200 Be-200 multipurpose amphibious aircraft releasing water in the Trans-Baikal National Park in Buryatia, southern Siberia, Russia. 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)

Siberian heatwave: Wildfires rage in Arctic, sea ice melts

Jul. 24, 2020 10:03 AM EDT

GENEVA (AP) — The U.N. weather agency warned Friday that average temperatures in Siberia were 10 degrees Celsius (18 Fahrenheit) above average last month, a spate of exceptional heat that has fanned devastating fires in the Arctic Circle and contributed to a rapid depletion in ice sea off Russia's Arctic...

Wealthier neighborhoods can claim a greater share of pollution primarily because they have larger homes.

Rich Americans spew more carbon pollution at home than poor

Jul. 20, 2020 3:47 PM EDT

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 by income,...

Climate change makes freak Siberian heat 600 times likelier

Jul. 15, 2020 5:15 PM EDT

Nearly impossible without man-made global warming, this year’s freak Siberian heat wave is producing climate change’s most flagrant footprint of extreme weather, a new flash study says. International scientists released a study Wednesday that found the greenhouse effect multiplied the chance of the...

Burger King addresses climate change by changing cows' diets

Jul. 14, 2020 12:07 PM EDT

Burger King is staging an intervention with its cows. The chain has rebalanced the diet of some of the cows by adding lemon grass in a bid to limit bovine contributions to climate change. By tweaking their diet, Burger King said Tuesday that it believes it can reduce a cow's daily methane emissions by about 33%....
