- Some folks asked if old climate models were just continuing observed linear increases in temperatures. This misrepresents what physics-based climate models do (they aren't curve fitting), but also ignores that in ~1970 there was little observed warming:
- Scientists have been publishing climate models since ~1970. A good way to evaluate their skill is to compare what they expected to happen in the years after the model was published to observed climate changes. It turns out most models were pretty spot-on:
- This is an updated version of Figure 1.9 in the recent (2021) IPCC 6th Assessment Report Wg1, which in turn is based on my Hausfather et al. 2020 paper, available (open access) here: agupubs.onlinelibrar...

- Back in 2010 there was a pretty outspoken cohort of climate skeptics arguing that natural cycles would lead to warming slowing down or stopping. While its nice to be proven correct, I wish for all our sakes that we had been wrong! www.realclimate.org/...

- Large volcanic eruptions have a major climate cooling effect. But the eruptions we've had in the past 170 years have been relatively mild compared to those in the more distant past. Here are climate model simulations of major eruptions since 1750 using FaIR:
