Researchers uncover the surprising cause of the Little Ice Age – “We may be underestimating future ice loss from the Greenland ice sheet”

AMHERST, Massachusetts, 15 December 2021 (University of Massachusetts Amherst) – New research from the University of Massachusetts Amherst provides a novel answer to one of the persistent questions in historical climatology, environmental history and the earth sciences: what caused the Little Ice Age? The answer, we now know, is a paradox: warming. The Little Ice […]

Sierra Nevada snowpack, a crucial water resource, could disappear in 25 years – “A low-to-no-snow future has massive implications for where and when water is stored in the western U.S.”

By Denise Chow 1 December 2021 (NBC News) – The Sierra Nevada snowpack, a major source of water for California, could largely disappear in 25 years if global warming continues unchecked, according to a recent study. The worrisome findings, published 26 October 2021 in the journal Nature Reviews Earth & Environment, have serious implications for California’s […]

Super Typhoon Rai leaves trail of destruction in Philippines – Desperation grows for 400,000 people – “Red Cross emergency teams are reporting complete carnage in the coastal areas. Homes, hospitals, school, and community buildings have been ripped to shreds.”

By Matt Hills 23 December 2021 (The Guardian) – Typhoon Rai has devastated the Philippines, killing at least 375 people, and causing damage in excess of $500m (£375m). The system developed on 13 December, tracked westwards across the Philippines on the 16th and 17th, before crossing the South China Sea on the 18th. Rai reached […]

World Bank’s 2021 Year in Review in 11 Charts: The Inequality Pandemic

By Venkat Gopalakrishnan, Divyanshi Wadhwa, Sara Haddad, and Paul Blake 21 December 2021 (World Bank) – From uneven economic recovery to unequal access to vaccines; from widening income losses to divergence in learning, COVID-19 has had a disproportionate impact on the poor and vulnerable in 2021. It is causing reversals in development and is dealing a […]

(a) Linear sea surface temperature (SST) trend (°C yr-1) for August of each year from 1982 to 2021. The trend is only shown for values that are statistically significant at the 95 percent confidence interval; the region is shaded gray otherwise. White shading is the August 2021 mean sea ice extent, and the yellow line indicates the median ice edge for Aug 1982-2010, (b, c) Area-averaged SST anomalies (°C) for August of each year (1982-2021) relative to the 1982-2010 August mean for (b) Baffin Bay and (c) Chukchi Sea regions shown by blue boxes in (a). The dotted lines show the linear SST anomaly trends over the period shown and trends in °C yr-1 (with 95 percent confidence intervals) are shown on the plots. Mean August SST warming trends from 1982 to 2021 persist over much of the Arctic Ocean, with statistically significant (at the 95 percent confidence interval) linear warming trends of up to +0.1°C yr-1 (a). Overall, Baffin Bay SSTs are becoming warmer in August with a linear warming trend over 1982-2021 of 0.05 ± 0.01°C yr-1 (b). Similarly, Chukchi Sea August mean SSTs are warming, with a linear trend of 0.06 ± 0.03°C yr-1 (c). Mean August SSTs for the entire Arctic (the Arctic Ocean and marginal seas north of 67° N) exhibit a linear warming trend of 0.03 ± 0.01°C yr-1. Graphic: Timmermans and Labe / NOAA

NOAA’s 2021 Arctic Report Card: Rapid and pronounced warming continues to drive the evolution of the Arctic environment

By T. A. Moon, M. L. Druckenmiller, and R. L. Thoman 6 December 2021 (NOAA) – As the influences of human-caused global warming continue to intensify, with the Arctic warming significantly faster than the globe overall, the 2021 Arctic Report Card (ARC2021) brings a broad view of the state of the Arctic climate and environment.

Aceredo was one of five villages that were inundated when the Lindoso Reservoir was built in 1992. Record drought in Spain reduced the reservoir’s water to its lowest level since it was filled.

Drought reveals abandoned Spanish village after 30 years underwater – Lindoso Reservoir level drops to record low

2 December 2021 (Love Exploring) – We’re used to reports that climate change will soon plunge the world’s beloved landmarks underwater. But this curious Spanish village has an opposite story: once engulfed by water, it recently re-emerged due to extremely low rainfall. Read on to discover the fascinating tale – plus see more amazing photos […]

17 December 2021 (CNN) – South Sudan is experiencing its worst floods in 60 years. The deluge began as early as June 2021, swallowing up homes, farms, and markets across swaths of the African nation. For years, South Sudan has seen wetter-than-usual wet seasons, and its dry seasons have become even drier. This twin problem […]

On 13 December 2021, Ice scientists at the American Geophysical Union (AGU) meeting in New Orleans warned that great cracks and fissures had opened up both on top of and underneath the Thwaites glacier, one of the biggest in the world, and it may fracture and collapse, possibly within five years.

Antarctica’s “doomsday” glacier: how its collapse could trigger global floods and swallow islands – “If Thwaites were to collapse, it would drag most of West Antarctica’s ice with it”

By Ella Gilbert 22 December 2021 (The Conversation) – The massive Thwaites glacier in West Antarctica contains enough ice to raise global sea levels by 65 centimeters if it were to completely collapse. And, worryingly, recent research suggests that its long-term stability is doubtful as the glacier haemorrhages more and more ice. Adding 65 centimeters to global sea levels […]

GENEVA, 25 October 2021 (WMO) – The abundance of heat-trapping greenhouse gases in the atmosphere once again reached a new record last year, with the annual rate of increase above the 2011-2020 average. That trend has continued in 2021, according to the World Meteorological Organization (WMO) Greenhouse Gas Bulletin. Concentration of carbon dioxide (CO2), the most […]
