Mitigation, adaptation, suffering
I’ve been struggling, more than usual, to find things to write about. Everything seems to just be a bit of a mess. The pandemic itself, how it’s been handled in some cases, and the protests in the USA, especially how … Continue reading
Constraining unforced variability
Pages 2k has a new Nature paper called Consistent multidecadal variability in global temperature reconstructions and simulations over the Common Era. What they do is present 2,000-year-long global mean temperature reconstructions using seven different statistical methods that draw from a … Continue reading
Early 20th century warming
I’ve noticed that Judith Curry is discussing the early twentieth century warming. The idea is that there was a period of warming during the early twentieth century that was similar to the warming we’ve experienced since the second half of … Continue reading
Confounding ECS estimates
Kate Marvel and colleagues have just published an interesting paper on how [i]nternal variability and disequilibrium confound estimates of climate sensitivity from observations. Essentially they compare three different ways of estimating Equilibrium Climate Sensitivity (ECS): atmosphere-only simulations with observed sea … Continue reading

Energy budgets
Stoat highlights an interesting paper that suggests that the rates of ancient climate change may be underestimate. I haven’t had a chance to really look at it, so if anyone has looked at it, and has any views, that would … Continue reading
Some thoughts on internal variability
Given that there’s been some discussion about internal variability in my previous post, and because there seems to have been interest elsewhere, I thought I would post some thoughts. A paper I was reading recently is Internal variability of Earth’s … Continue reading
Models don’t over-estimate warming?
I thought I might write about the new paper by Jochem Marotzke and Piers Forster called Forcing, feedback and internal variability in global temperature trends. It’s already been discussed in a Carbon Brief post called claims that climate models overestimate … Continue reading
A minimal model for climate sensitivity
I’ve written a number of times about energy balance models. I think these are nice ways to estimate effective climate sensitivity (both transient and equilibrium) but they are quite simple and do suffer from some issues. For example, they are … Continue reading
The length of the “pause”?
In a recent post, Judith Curry highlighted a new paper by Shaun Lovejoy called Return periods of global climate fluctuations and the pause. This is a follow-up of an earlier paper that concluded that the probability of a centennial scale … Continue reading

What does Judith mean by natural?
Gavin Schmidt recently addressed Judith Curry’s 50:50 argument in a Realclimate post. In Judith’s response (which doesn’t really say much) she finishes with, I do regard the emerging realization of the importance of natural variability to be an existential threat … Continue reading
