This April many leading experts will come together for the World Adaptation Forum in Budapest to talk about our rapidly changing planet.

My talk will be titled:
Beyond Known Climate: Adapting to Unprecedented Change

Please join us in Budapest or online.

Ocean Heat Content Sets Another Record in 2025

'Global ocean warming continued unabated in 2025 in response to increased greenhouse gas concentrations and recent reductions in sulfate aerosols'

I'm hoping this preliminary @mercatorocean.bsky.social estimate for 2025 is wrong...🫣

10 years after the Paris Agreement, we have reached a '3-year average global temperature anomaly of +1.5°C in 2 or more datasets'!

And we can't blame El Niño for this, as ENSO was on average negative during this period.

The Paris Agreement was doomed from the start..

1/ We were thrilled to see 50+ MPs and Peers at the Overlapping Illness Alliance drop-in last week.

Thanks to your emails, nearly 80% of MPs got an invite, one even said it was the most letters they'd ever had about an event. Your support genuinely made a difference.

The last time a month was below the 1850-1900 average is now 589 months ago!

October 1976 was -0.14°C:

This seems important‼️

Also with regards to impacts of IMO 2020 shipping desulphurization:

"This shift in the dynamic response of the climate system to Marine Cloud Brightening (MCB) appears to be linked to the Atlantic Meridional Overturning Circulation (AMOC) response to climate change."

We probably need to go back to ~350 ppm CO₂ equivalent for temperatures to stop rising.

We are now above 573 ppm (GHG forcing of +4.1 W/m²).

That's without aerosols cooling things down.

There's too much uncertainty to be sure, but going back to 350 ppm is already a Herculean task.

No one should be surprised when a planet that accumulates heat more than twice as fast starts to see temperatures go up more than twice as fast.

This isn't rocket science, but we do need more of these NASA satellites. 🌍🛰

To keep us from going blind.
