Map data using @CopernicusEU ERA5 reanalysis. Comparing temperature to 1981-2010 average.
USA 🇺🇸 preliminary data suggests they had 5th hottest year on record. Strongest heat in the west. Note USA recorded a new world record for reliable hottest world temperature, 54.4 °C (129.9 °F) on 16 August.
Awaiting official verification from neighbouring countries.
Parts of Canada were among few places in the world which showed slightly cooler than normal for 2020. Not that warm in parts of Alaska either.
Some tremendous heat in 2020 for South America. Paraguay 🇵🇾 set a new all time heat record and likely recorded hottest year on record (awaiting something more official though). Brazil 🇧🇷 also saw countless records broken.
Argentina 🇦🇷 officially had 2nd hottest year on record.
Africa was warmer than normal almost everywhere.
Not seeing any official country reports for 2020 yet. If you know of any, please do speak up 👍
India 🇮🇳 recorded 8th warmest year on record. Central Asia was one of the few places which recorded some very cold weather in 2020.
Oh Siberia...
Off the scale. Some places average around 7 °C warmer than normal for the entire year of 2020.
The Arctic Circle heat record was broken here. Siberian town, Verkhoyansk recorded 38° C (100.4° F) on June 2020.
Brutal and record breaking cold spell ongoing in Asia (late December into early January 2021) but 2020 as a year was still hottest on record for Japan 🇯🇵
South East Asia...
Maritime continent heavily influenced by surrounding sea surface temperatures. It was warmer than normal across the board. Awaiting verification for country specifics.
2020 will be remembered for devastating typhoon in the Philippines and flooding in Vietnam.
Australia 🇦🇺 made world headlines early in 2020 (seems like a lifetime ago), mainly for devastating wildfire. Also some record breaking heat to end the year. Cooler than normal in the south for 2020 average, hot interior.
Should get New Zealand 🇳🇿 verification soon.
Arctic and Antartica.
I think the images speak for themselves. Official Polar rankings coming soon.
5 years in a row of category 5 hurricanes. This has not happened in recorded history going back to 1851.
#Iota is about to make landfall as a powerful category 5 storm. Nicaragua and Honduras can't take another major hurricane. It was only 2 weeks since category 4 #Eta.
The track of #Eta overlaid projected landfall of #Iota is insane. Two major hurricanes within a fortnight in November. Eta struck Nicaragua on 3 November.
