Happy to share our paper in ‪@science.org‬ 'Observed trend in Earth energy imbalance may provide a constraint for low climate sensitivity models' | Science www.science.org/doi/10.1126/...
Observed trend in Earth energy imbalance may provide a constraint for low climate sensitivity models
Climate forcings by greenhouse gases and aerosols cause an imbalance at the top of the atmosphere between the net incoming solar radiation and outgoing longwave radiation from Earth. This Earth energy...

It's horrifying to see #Melissa intensifying right up to landfall - I dread to think what will happen in Jamaica, with up to a metre of rain forecast 🧪

But it's clear why Melissa is so powerful - it was fuelled by waters made abnormally warm by global heating:

Hurricane Melissa is being fuelled by exceptional ocean heat
The monster hurricane pummelling Jamaica is powered by abnormal sea surface temperatures in the Caribbean, which were made at least 500 times more likely by global warming

Our climate seems to be more sensitive to greenhouse gases than we thought, which means we have to up our decarbonisation efforts.

A pdf of the paper is now available here: cicero.oslo.no/en/articles/...
Observed trend in Earth energy imbalance may provide a constraint for low climate sensitivity models
Climate models that give a low warming from increases in greenhouse gases do not match satellite measurements. Future warming will likely be worse than thought

The inability to produce a strong positive shortwave and strong negative longwave Earth energy imbalance trend is found to be a robust feature in the low climate sensitivity models, especially for models with a climate sensitivity below 2.5 kelvin.

"Emissions have basically stabilized and accordingly the annual increase in atmospheric CO2 has stabilized (it spiked in 2016 and 2024 due to El Nino events but if you neglect those individual spikes the data show a clear leveling)," Mann.

That, seriously, is about as wrong as it is possible to be:
