Image of the Day: Antarctica melts under its hottest days on record

By Kasha Patel 21 February 2020 (NASA) – On 6 February 2020, weather stations recorded the hottest temperature on record for Antarctica. Thermometers at the Esperanza Base on the northern tip of the Antarctic Peninsula reached 18.3°C (64.9°F)—around the same temperature as Los Angeles that day. The warm spell caused widespread melting on nearby glaciers. The warm […]

“Fast and dramatic” permafrost thaw will double previous estimates of potential carbon emissions – “Forests can become lakes in the course of a month”

By Natacha Larnaud 4 February 2020 (CBS News) – Rapidly thawing permafrost in the Arctic has scientists worried. According to a new study published Monday in the journal Nature Geoscience, the ice that holds the soil together is melting, causing hillsides to collapse and massive sinkholes to open up as a result. And that dramatic disruption to […]

Precipitation averages in the contiguous U.S. for overlapping two-year calendar periods, 1895-2019. The period 2018-19 was the wettest of these, with 69.43” coming in well above the previous record of 68.62” from 1982-83. Graphic: NOAA / NCEI

Second wettest year in U.S. history – Warmest year on record in Alaska

By Bob Henson 8 January 2020 (Weather Underground) – Capping a spectacularly soggy period that spanned parts of two calendar years, the contiguous United States saw its second wettest year on record in 2019, according to NOAA’s annual summary issued on Wednesday. The national average temperature wasn’t especially hot by recent standards, but there were […]

New Zealand glaciers turn brown from Australian bushfires’ smoke, ash and dust – May increase glacier melt in 2020 by 30 percent

By Eleanor Ainge Roy 1 January 2020 WANAKA (The Guardian) – Snow and glaciers in New Zealand have turned brown after being exposed to dust from the Australian bushfires, with one expert saying the incident could increase glacier melt this season by as much as 30 percent. On Wednesday many parts of the South Island woke […]

2010-2019: Earth’s hottest decade on record marked by extreme storms, deadly wildfires – “The climate of the 20th Century is gone. We’re in a new neighborhood.”

By Bob Berwyn 19 December 2019 (InsideClimate News) – Deadly heat waves, wildfires and widespread flooding punctuated a decade of climate extremes that, by many scientific accounts, show global warming kicking into overdrive. As the year drew to a close, scientists were confidently saying 2019 was Earth’s second-warmest recorded year on record, capping the warmest […]

2019 was hottest year on record in Russia, 2nd hottest in Arctic Circle – Warmest New Year’s Eve on record in Anchorage

MOSCOW, 30 December 2019 (AFP) – This year was the hottest ever registered in Russia, the country’s weather chief said on Monday, as climate change pushes global temperatures to record highs. “This year in Russia was the hottest for the entire period of instrumental observations,” the head of the Gidromedtsentr weather service, Roman Vilfand, told […]

World’s supply of fresh water in trouble as mountain ice vanishes – 1.9 billion people at risk from mountain water shortages – “The most important water towers are also among the most vulnerable”

By Alejandra Borunda 9 December 2019 (National Geographic) – High in the Himalaya, near the base of the Gangotri glacier, water burbles along a narrow river. Pebbles, carried in the small river’s flow, pling as they carom downstream. This water will flow thousands of miles, eventually feeding people, farms, and the natural world on the vast, […]

Alaska’s Columbia glacier began rapidly retreating around 1980, and its leading edge has moved more than 20 kilometers inland. These images, captured by the joint NASA / U.S. Geological Survey Landsat satellites, were stitched together into a video to show the glacier’s dynamic evolution from 1972 to 2019.

Video: 47 years of satellite images show retreat of Alaskan’s Columbia glacier

By Carolyn Gramling 10 December 2019 SAN FRANCISCO (Science News) – A mesmerizing new series of images shows the retreat of Alaska’s Columbia glacier over the last 47 years in gorgeous, excruciating detail. The images were presented December 10 at the American Geophysical Union’s annual meeting. Landsat satellites operated by NASA and the U.S. Geological […]

Greenland losing ice seven times faster than in the 1990s – Sea level rise from Greenland melt tracking highest climate projections

10 December 2019 (Utrecht University) – Greenland is losing ice seven times faster than in the 1990s and is tracking the IPCC’s high-end climate warming scenario, which would see 40 million more people exposed to coastal flooding by 2100. The findings, published in Nature today, show that Greenland has lost 3.8 trillion tonnes of ice […]

New photos vs old: comparisons show dramatic Swiss glacier retreat – “We have never seen such a fast rate of glacial decline since the measurements have started”

By Denis Balibouse 25 November 2019 THE FURKA PASS, Switzerland (Reuters) – On the hairpin bend of a Swiss mountain pass, a Victorian-era hotel built for tourists to admire the Rhone Glacier has been abandoned now that the ice has retreated nearly 2 km (1.2 miles) uphill. Where mighty glaciers once spilled into Swiss valleys […]
