Taking into account all known factors, the planet warmed 0.2 °C more last year than climate scientists expected. More and better data are urgently needed.

    Given that the climate models can’t even agree on the ECS, and we’re having an increasing amount of evidence pointing towards the ECS value being significantly higher than previously estimated, who is surprised, really?

    We’re fucked. We’ve been fucked for a while now. Just sit back and enjoy the ride.

    I thought it was because of the ban on a specific high sulfur fuel from cruisers that was causing short term global cooling.

      From the article:

      In 2020, new regulations required the shipping industry to use cleaner fuels that reduce sulfur emissions. Sulfur compounds in the atmosphere are reflective and influence several properties of clouds, thereby having an overall cooling effect. Preliminary estimates of the impact of these rules show a negligible effect on global mean temperatures — a change of only a few hundredths of a degree. But reliable assessments of aerosol emissions rely on networks of mostly volunteer-driven efforts, and it could be a year or more before the full data from 2023 are available.
