I'm rather taken with this elegant visualization of @ClimateChange from the BBC. Particularly as it clearly shows how anomalous 2023 was.

It's a Ridgeline plot (also sometimes called a joyplot, after the iconic album cover from the band #JoyDivision).

I just wish they'd used a pre-industrial average as the baseline. 2023 was 1.48°C warmer than pre-industrial times according to the Copernicus data.

@steve
Gorgeous, gorgeous plot!

But I agree, the appropriate baseline is not a WMO 30 year sliding baseline such as this one, 1991-2020. Correct interpretation might require the baseline be the last 10,000 years.

Perspective is everything.

As the most abundant greenhouse gas in our atmosphere, CO2 levels have varied widely over the course of the Earth’s 4.54 billion year history.

@ScottAkenhead @steve To me, the amazing thing is how stable Earth's temperature has been. Millions of years, never outside the range that can support carbon-water based life.

Perhaps this is one planet in billions. Perhaps any number of things could have made us like Mars or Venus. But we are like a gambler who has flipped a coin and it has come up heads 100 times in a row. If it had ever come up tails, we wouldn't be here thinking 100 heads in a row is normal.

@Paul_Friesen @ScottAkenhead @steve IIRC if it weren’t for the evolution of life Earth’s atmosphere would be like that of Mars
@stuvx @Paul_Friesen @ScottAkenhead @steve and we have a magnetic field which Mars really doesn't have.
