Ok comms gurus… if we’re talking about ocean heat content and earth’s energy imbalance which units are preferable: ZJ and ZJ per year or W/m²year and W/m². Or something else. Or putting everything in terms of some energy equivalent like how much energy humans use each year.

🚨The most important NASA graph in the world has another 6 months of data, and it looks even worse. 🚨 NASA CERES satellites measure how much sunlight Earth absorbs and how much heat is radiated back to space. The difference is heat accumulation, which has more than tripled over the past 26 years!

Are calling me an elephant? 😅 I expect discussions might have been somewhat similar to those described in the minutes of the IPCC AR6 SR SPM talks. When aerosols were left out, because "INDIA called for deleting it" And adding the invaluable figure WG1 SPM.2 was "opposed by SAUDI ARABIA and INDIA"

"Overshoot" is where you first exceed a threshold (say 1.5C) and return later. Yes, yes, there are / were no overshoot pathways. These are the "no overshoot" scenarios from AR6. One can question whether they were ever feasible, but they now involve time travel. 3/

According to this modeling atudy, aerosols limited warming of the Mediterranean Sea by about 1°C. The aerosol termination shock from land and shipping desulphurization is resulting in a permanent temperature increase. And the greenhouse gas forcing is still increasing at a record rate.
