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...

The warming effect of black carbon must be reassessed in light of observational constraints

Warming from BC stays uncertain despite observational constraints.

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:

Repost this if you’re old enough to remember when they tried to convince us that “global warming stopped in 2008” (or whenever).
