2020 has been truly unprecedented year in northern Siberia. Year-to-date temperatures are up to 7.7°C warmer than normal.

This persistent warmth will be one of the main stories of the global climate in 2020.

@myytinkertojat haha. Do you have any arguments supporting your claims or are you just hand-waving? November 1998 featured La Nina in Pacific with extensive cold in Siberia.

The first 10 months of the year have been up to 7°C warmer than normal in northern Siberia. That is a huge anomaly for such a long stretch of time.

Europe is under #heatwave. Increasing trends of heatwaves due to global warming is one of the most established fact in the climate change attribution studies.

This is how much hot days (Tmax > 30°C) have increased in Europe in 1961-2019:

June 2020 temperature anomalies in Arctic Siberia were striking.

The maximum temperature anomaly in ERA5 0.25° gridded data was 10.3°C, which is the highest value in the Northern Hemisphere at any summer month since 1979 (so in the whole dataset).

How much faster is the #Arctic warming than the global average? Locally up to 5 times faster, but in general 3-4 times.

Inspired by @anttilip and @ClimateOfGavin tweets on this topic.

Extremely anomalous warmth expected near the Arctic Circle in Western Siberia in the coming days.

Temperatures can rise 25-30°C higher than normally at this time of the year.

Possibly the most positive 5-day period of Arctic Oscillation you have ever seen.

Anomalously low pressures inside the Arctic circle, surrounded by high pressures at mid-latitudes all over the globe.

Brrr! Cold morning across Fennoscandia. -8.1°C recorded in Salla is now the season's lowest reading in Finland so far.

Tens of millions people in the Western Europe are now probably experiencing the most concrete effect of human-induced climate change during their lifetime so far.
