In 1988, James Hansen confidently predicted that the world would be about 1 degree Celsius warmer today than it was then. Actually, he offered three scenarios: A, “business as usual,” with rapidly rising carbon dioxide emissions, which would bring that 1 degree; B, “most plausible,” with emissions remaining constant at 1988 levels, which would make […]

If you run in the right circles, you might encounter someone who breathlessly tells us that the downward trend in estimates of climate sensitivity (how much added warmth comes from added atmospheric CO2) got turned around by a new study in Nature Climate Change, and we’re back to a best estimate of Equilibrium Climate Sensitivity

Just came across this, and it’s stunning. Those who charge CAGW skeptics with being anti-science need to take a look at this and consider carefully: Who’s been trending right about how much warming comes from adding CO2 to the atmosphere? For in-depth discussion, see Nicholas Lewis, “Pitfalls in climate sensitivity estimation,” Part 1, Part 2, and
