https://www.economist.com/science-and-technology/2026/07/15/the-rate-at-which-earth-is-absorbing-energy-is-alarming-climate-scientistsReto Knutti, a climate scientist at ETH Zurich, says the rate at which the EEI is going up suggests that near-term warming could be anywhere from 10% more to 30% more than the current consensus.

Late last year more than 50 researchers in the field published a paper which asserted that the strong upward trend in the imbalance is difficult to reconcile with climate models. [We are now left in] little doubt that the real world signal has left the envelope of model internal variability.
This is not just a problem for science. As Maria Rugenstein of Colorado State University puts it, Lots of people are using these models for impact assessment, for carbon budgetsfor anything we say about the future, we use these models which cannot reproduce the currently observed energy imbalance.

[James Hansen's] projections see warming since the 19th century reaching 2°Cand thus surpassing the limit enshrined in the Paris agreement on climate in 2015by the end of the 2030s.

(5,427 posts)the difference between energy in and energy out. Earth is currently trapping energy by the Greenhouse Effect and not reflecting or emitting it as much as it takes in. The EEI (in Watts) is very large. per wiki, "During 2005 to 2019 the Earth's energy imbalance averaged about 460" terawatts (10^12)*. In 2012 to 2024, the imbalance is about twice as large as the period 1971-2006.
The imbalance between energy-in and energy-out has grown in the 21 century, and the rate of increase of the imbalance is accelerating. It looks like positive feedback processes (like melting ice exposing darker seawater which absorbs more heat than ice) are kicking in. The rate of change is now greater than ANY model predictions, per the article. Something is contributing to the imbalance that we don't know about, and it's a biggie.
Like the saying goes, reality is what takes you by surprise.
*to put that 460 terawatt imbalance into perspective, wiki says the total installed global solar capacity is a little over 1 terawatt.

This study is the first I've heard of that tries to quantify "reality", in the sense of reality surprising us. We will see unexpected unknown variables manifest themselves in unpredicted ways. With any luck we'll get some negative feedbacks slowing the rate of change, but with any luck I'll also hit the lotto.
For those who can: install solar panels and storage batteries. Community resources like that saved lives after Maria flattened Puerto Rico and the power failed. Medical equipment and communications were powered that way.
DISTRIBUTE THE POWER! electrical and political.

The oceans will boil and all life on earth will perish.
Our last chance was ruined by Trump.

We had a slim chance, and blew it.
