Map showing the age of sea ice in the Arctic at winter maximum in 2000 (left, week of March 18) and 2020 (right, week of March 21). Ice older than 5 years (white) is very rare today; only a small ribbon remains along the islands of the Canadian Arctic. Age is a stand-in for ice thickness and durability; young ice is thinner and more likely to melt in the summer. NOAA Climate.gov map, based on data from the National Snow and Ice Data Center.

Sea ice loss and extreme wildfires mark another year of Arctic change – “The transformation of the Arctic to a warmer, less frozen, and biologically changed region is well underway”

8 December 2020 (NOAA) – NOAA’s 15th Arctic Report Card catalogs for 2020 the numerous ways that climate change continues to disrupt the polar region, with second-highest air temperatures and second-lowest summer sea ice driving a cascade of impacts, including the loss of snow and extraordinary wildfires in northern Russia. The Arctic Report Card is […]

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 […]

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 […]

Falling up: A look back at the 2019 Arctic summer – New record daily lows for sea ice extent in July and early August

3 October 2019 (NSIDC) – Arctic sea ice began its autumn regrowth in the last 12 days of September, with the ice edge expanding along a broad front in the western Arctic Ocean. Overall, the summer of 2019 was exceptionally warm, with repeated pulses of very warm air from northern Siberia and the Bering Strait. […]

If warming exceeds 2°C, Antarctica’s melting ice sheets could raise seas 20 meters in coming centuries

By Georgia Rose Grant and Timothy Naish 2 October 2019 (The Conversation) – We know that our planet has experienced warmer periods in the past, during the Pliocene geological epoch around three million years ago. Our research, published today, shows that up to one third of Antarctica’s ice sheet melted during this period, causing sea levels to rise […]

Honest Government Ad: We’re Fucked

2 Sep 2019 (Juice Media) – The Government™ has made an ad about the state of the world as we enter the third decade of the 21st century, and it’s surprisingly honest and informative. Global Climate StrikeWorldwide Rebellion A feedback loop is the scientific term for when a species uses its own ignorance to screw […]

Large rivers of melting water form on an ice sheet in western Greenland on 1 August 2019 and drain into moulin holes that empty into the ocean from underneath the ice. The heat wave that smashed high temperature records in five European countries a passed over Greenland, accelerating the melting of the island's ice sheet and causing massive ice loss in the Arctic.

Bizarre happenings in the Arctic: Lightning, tropical moisture, and more

By Bob Henson 14 August 2019 (Weather Underground) – You’ll have to forgive the Arctic. It’s had a rough summer. Sea ice is running neck and neck with 2012 for the lowest values on record for this time of year. Wildfires are ringing the Arctic, pouring more carbon dioxide into the air than in any comparable period in 17 […]

Arctic fires fill Northern Hemisphere skies with soot

By Kasha Patel 1 August 2019 (NASA) – In June and July 2019, more than 100 long-lived and intense wildfires blazed within the Arctic Circle. Most of them burned in Alaska and Siberia, though a few raged even in Greenland. As these fires lofted thick plumes of smoke into the skies, they also launched megatons of tiny, harmful particles into the […]

WMO: July 2019 equaled or surpassed hottest month globally – World is on track for the 2015-2019 period “to be the five hottest years on record”

1 August 2019 (WMO) – According to the new data from the World Meteorological Organization and Copernicus Climate Change Programme, July 2019 at least equalled, if not surpassed, the hottest month in recorded history. This follows the warmest ever June on record. The data from the Copernicus Climate Change Programme, run by the European Centre […]

Siberia forest fires spark potential “disaster” for Arctic – 12 million hectares have burned in Russia this year – “The most important event on the planet right now? Arctic climate chaos.”

30 July 2019 (AFP) – Gigantic forest fires have regularly raged through the vast expanses of Russia’s Siberia, but the magnitude of this year’s blazes has reached an exceptional level with fears of a long-term impact on the environment. As fires sweep across millions of hectares enveloping entire cities in black smoke and noxious fumes, […]
