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

A bit more about clouds

A few years ago I posted a video by Andrew Dessler that was discussing whether or not Equilibrium Climate Sensitivity could be less than 3oC. The bottom line was that the best estimate for ECS is about 3oC. Given that … Continue reading

Kate Marvel on clouds

Although we are confident that adding greenhouse gases to the atmosphere will cause the planet to warm, exactly how much we will warm is uncertain (the IPCC likely range for a doubling of atmospheric CO2 is 1.5oC to 4.5oC). A … Continue reading

What a surprise …. not

To the surprise of no one, Nic Lewis has found many serious problems with the recently published Marvel et al. paper (also discussed here and here). Even less of a surprise is Andrew Montford lapping up Nic’s claims with glee. … Continue reading

Forcing efficacy

There’s a new paper, discussing climate sensitivity, by Marvel, Schmidt, Miller & Nazarenko called Implications for climate sensitivity from the response to individual forcings. Before I discuss the paper, I should really advertise the lead author’s blog, arguably one of … Continue reading
