Understanding past climate events and trends to constrain near-future climate risk
The global mean surface temperature record —combining sea surface and near-surface air data— is central to understanding climate variability and change.

High warming rate fuels record-breaking weather
The longer our measurements, the fewer record-breaking events we should observe.
The opposite is the case - many more records and higher record margins
I summarise the key takeaways of our @natrevearthenviron.nature.com article in a guest post.

How long does it take until we detect forced signals in global and regional land carbon fluxes?
And can we use dynamical adjustment to reduce the noise and shorten the detection time?

A new paper led by Sebastian Sippel just appeared in Nature arguing that ocean temperature measurements in the early 20th century have a cold bias.
It's a fun story illustrating the process of scientific discovery, so let me talk about it a bit. 🧵

In a new paper led by Sebastian Sippel published in Nature today, we show that the early 20th century global ocean surface temperatures and thereby global mean surface temperature were warmer than previously thought.
