Why is future sea level rise still so uncertain?

Real Climate

Meanwhile, note that the factors listed above involve the whole Earth system: the oceans, the cryosphere, the atmosphere, the solid earth and lithosphere, and a full range of scales, from the city block and shoreline, to ice dynamics that change over kilometers, to GRD footprints, to the whole global ocean. 2020) or Sadai et al.

The CO2 problem in six easy steps (2022 Update)

Real Climate

For some parts of the spectrum, the IR can be either absorbed by CO 2 or by water vapour or by clouds, but taking those overlaps into account we find that 50% of the greenhouse effect is from water vapour, 25% from clouds, and about 20% from CO 2 and the rest absorbed by ozone, aerosols, and other trace gases ( Schmidt et al, 2010 ).

“It’s [the albedo is] kept the same” [False – for instance here is a paper (Loeb et al, 2020) comparing the changes in albedo in models to the CERES observations]. It is still the case that variations in cloud feedbacks are the dominant source of variability of climate sensitivity in models (Zelinka et al, 2020).
