High resolution images from satellite and from eddy-resolving ocean circulation models point to an ongoing decline of the Atlantic overturning circulation, a key ocean current for our climate. Read more about it in my new blog article. 🌊

RealClimate: High-resolution ‘fingerprint’ images reveal a weakening Atlantic Ocean circulation (AMOC)

The #AMOC is the reason for Europe’s mild climate. Evidence that it is slowing has been piling up over the years – it now is likely at its weakest in at least a millennium, and it may even be approach...

This is absolutely staggering.

Record warm ocean temperatures continued in September across the North Pacific Ocean, with a number of consequential impacts (including on downstream weather patterns).

This graph shows the average for a band across the midlatitudes for every September from 1854-2025 using @noaa.gov ERSSTv5 data.

Green line graph time series of average sea surface temperature anomalies for each September from 1850 through 2025 for only the midlatitude region of the North Pacific Ocean. There is large interannual variability, but an overall long-term increasing trend. Anomalies are computed relative to a 1981-2010 baseline. 2025 is a record high.

Probably not quite as old as this though.

Electrification is vastly more efficient than combustion technologies:

🚘 An electric car uses about 75% less final energy than an ICE car.

🔥 A heat pump delivers about 4x more heat for the same energy input.

Note: Of course the exact efficiency and saving will differ between models and context.

At the people’s vote march of over 1 million people, the news crews were huddled around a group of half a dozen noisy brexiters. They’re children in a playground chasing their adrenaline not the news.
