Dust from Sahara has turned Andorra into a martian landscape! #andorra

🎥 @montpackers

You can see how the jet stream meanders south into North Africa, ideal setup for transporting plumes of dust into Europe.

Very impressive.

Insanely impressive satellite imagery from @eumetsat captures the plume of Saharan dust erupting north out of Africa.
Dust is bad for the snow pack. The albedo changes and the snow is able to melt faster.
It is all linked to the extreme contrast setup in Europe.

Remarkable with blizzards on the way this weekend further north.

Skiing in the sand... I mean snow.

Truly remarkable scenes emerging from parts of Europe as thick layer of Saharan dust blankets ski resorts today.

Saharan dust blanets parts of Europe today.

Ski resorts are turning a remarkable brown. Extreme warmth reported in southern Europe while cold builds in the north.

This is how things looked in Andorra today.

Nearly 30°C in Palermo, Sicily today.

A fraction short of the February record.

How is 2021 going for you?

This is how January 2021 went for the Northern Hemisphere. Exceptionally warm in North America and Arctic. Some places average more than +10°C warmer than normal.

Very cold Russia, Asia and cool western northern and western EU.

THREAD
For the rest of the world, North Africa, Middle East and Black Sea areas stood out as very warm, some impressive records there. Tibetan plateau also was remarkably warm.

La Niña signature still present with a slightly cool month for Antarctic.
Canada 🇨🇦 in more detail...

This is just insane. The whole country warmer than normal, by a lot.

It is official. 2020 was the joint hottest year on record for Planet Earth 📈

This was the hottest year on record for Europe.

Data @CopernicusEU

[THREAD]

Official report from @CopernicusEU ⬇️

climate.copernicus.eu/copernicus-202…
So 2020 was ties hottest with 2016?

This is what 2016 looked like. Exceptional Arctic warmth like 2020 but slightly different places to 2020.

There is an important difference between 2016 and 2020 though.

Hottest year on record for Europe?

The following countries so far have confirmed 2020 as:

Hottest year on record: 🇳🇴🇸🇪🇫🇮🇪🇪🇱🇻🇨🇭🇫🇷🇳🇱🇧🇪

2nd hottest: 🇵🇱🇩🇰🇩🇪
3rd hottest: 🇬🇧
5th hottest: 🇦🇹

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.

Earth has a fever in more ways than one. Some places averaged + 5-7 °C warmer than normal for the ENTIRE YEAR of 2020.

An enormous area of anomalous warmth plagued Arctic Siberia effectively all year but it was not just the Arctic where we saw record shattering warmth.

THREAD
Another way of looking at it... Very few cold blobs left. La Niña developed and shows up in the Pacific.

The climate is not changing uniformly, the Arctic is warming much faster than the rest of the world.

Data: @CopernicusEU and compares to 1981-2010 average.
JANUARY was joint hottest January globally on record according to NASA GISTEMP v4 (joint record with 2016).

Profound winter warmth for North America plus Europe and Asia.
