From unprecedented wildfires across the US to the extraordinary heat of Siberia, the impacts of climate change were felt in every corner of the world in 2020. We have come to a "moment of truth", United Nations Secretary General Antonio Guterres said in his State of the Planet speech in December. "Covid and climate have brought us to a threshold."
BBC Future brings you our round-up of where we are on climate change at the start of 2021, according to five crucial measures of climate health.
1. CO2 levels
The amount of CO2 in the atmosphere reached record levels in 2020, hitting 417 parts per million in May.
2. Record heat
The past decade was the hottest on record. The year 2020 was more than 1.2C hotter than the average year in the 19th Century.
3. Arctic ice
Nowhere is that increase in heat more keenly felt than in the Arctic.
4. Permafrost
Across the northern hemisphere, permafrost – the ground that remains frozen year-round for two or more years – is warming rapidly.
5. Forests
Since 1990 the world has lost 178 million hectares of forest (690,000 square miles) – an area the size of Libya.
As well as showing how much the climate has changed already, these five climate indicators also point the way to the solutions that can curb global warming to safer levels by the end of the century.
As Guterres noted in his December State of the Planet speech, "Let's be clear: Human activities are at the root of our descent towards chaos. But that means human action can help solve it."

Riots.. Don’t forget the riots brought about by climate change.

Good morning, America.
I think I’ll have a shot of whisky for breakfast because I’m an American.

Not even close to a record. For most of the history of life on Earth CO2 levels were well above 1,000 ppm and as much as 7,000 ppm.
#FakeScience vs #RealScience
: ) They’d call that a fake chart and ban you from the information superhighway.
Hey wait a minute now...you’re an old timer too. You’re non-essential.
Circling back to #1...CLASSIC
At this point, all truth is non-essential. Real science is non-essential.
The way the Dems are playing it earning a living is non-essential.
That's usually the first talking point.
TRUE. Socialists/Totalitarians are non-essential. Despite history, most don’t see it yet.
Newbie on thread is smart. : )
Where’s my Michael Mann autographed hockey stick?
BS
Letr's hope so. The 1800's were the tail end of the Little Ice Age.
