[MCN] 90F in the Arctic? A reminder

[Lance Olsen]

Google AI Overview
Yes, temperatures of 90°F (32.2°C) and higher have been recorded in the Arctic Circle. Driven by climate change, these extreme temperatures are becoming more frequent as the Arctic warms at a rate nearly three times faster than the rest of the planet.

Specific instances of these extreme temperatures include:
Verkhoyansk, Russia: This Siberian town, normally one of the coldest places on Earth, officially recorded an all-time Arctic high of 100°F (38°C) in June 2020. This record was officially verified by the World Meteorological Organization.
Anchorage, Alaska: Though located in the subarctic, the city shattered its all-time record high, reaching 90°F (32.2°C) in July 2019.
Deadhorse, Alaska: Situated near the Arctic Ocean, this town reached an unprecedented 89°F (31.6°C) during a severe summer heatwave.

These extraordinary heatwaves have major environmental consequences, including massive sea ice loss, widespread wildfires, and the thawing of permafrost, which releases trapped greenhouse gases like methane into the atmosphere.

“Extreme downpours are now happening 30 percent more often nationwide than in 1948 ….. 
Moreover, the largest annual storms now produce 10 percent more precipitation, on average” 
(Madsen and Willcox, 2012).

And

“Despite uncertainties in total precipitation changes, extreme daily precipitation averaged over 
both dry and wet regimes shows robust increases in both observations and climate models over 
the past six decades. Climate projections for the rest of the century show continued intensification 
of daily precipitation extremes. Increases in total and extreme precipitation in dry regions are 
linearly related to the model-specific global temperature change, so that the spread in projected 
global warming partly explains the spread in precipitation intensification in these regions by the 
late twenty-first century. This intensification has implications for the risk of flooding as the climate 
warms, particularly for the world’s dry regions” (Donat et al 2016).
