High emission scenarios

I thought I might briefly reflect, again, on the whole RCP8.5 discussion. In case anyone missed it, there has been a lengthy online discussion about RCP8.5, which is a concentration/forcing pathway that leads to a change in forcing of 8.5 … Continue reading

This. Is. Not. Science’s. Job.

My title is a paraphrase of something Michael Tobis said during the marathon Twitter discussion about RCP8.5, which I thought I would use to discuss something about science communication that I’ve mentioned a number of times before. During the RCP8.5 … Continue reading

Climate sensitivity and decadal temperature variability

There are some who argue that natural/internal variability can play a role in driving long-term warming, and – hence – could explain a substantial fraction of recent warming. This, however, creates a bit of a paradox; if the system responds … Continue reading
