We hear a lot about central outcomes of climate change. For example, under the new "medium" scenario (e.g. current policies continuing), the world warms around 2.9C by 2100. But these numbers mask some massive uncertainties in how the climate actually responds to our emissions.

@hausfath@fediscience.org This is a shicking analysis. I thought, we were on a path to 2.8 degrees. But obviously, 3 or more degrees are likely as well.

These arise from two factors: carbon cycle feedbacks – how the biosphere and ocean's ability to absorb carbon changes as we emit more and the world warms, and climate sensitivity – how the interplay of feedbacks like water vapor, clouds, snow and ice, etc. respond to warming.
