Andrew Bolt has posted some comments Prof. Judith Curry made to the US House of Reps. Committee on Science, Space and Technology hearing this week here
“The climate has been warming since the 1700s, okay, since the end of the ‘Little Ice Age,’” Curry explained. “We don’t know what’s causing that warming in the 18th Century, in the 19th Century — it’s not attributed to humans.”
Much as I respect Prof. Curry, she has explained the fact rather badly. It isn’t the unusual warming that is the problem but the fact of what caused the Little Ice Age (LIA) that is the unusual and inexplicable problem.
What is causing the warming in the 18th Century etc, is not being caused by anything but that the cause of the previous cooling has disappeared, which is the explanation.
Just imagine throwing someone into an icy pond of water, and then afterwards, thinking better of it, rescuing them and watching them warm back to normal body temperature as their metabolism works overtime. So too the Earth recovering from the previous ice age, here a little one.
What Prof. Curry has not stressed is that it’s the ice ages that are the unusual events which cause the cooling and species extinctions, not the utterly predictable warming that happens when the cause of the ice age is no longer present.
It’s the ice ages that are the mystery, not the subsequent warming!
They have it exactly back to front.
Update: As the Earth warms back to its previous state before the LIA, so too will the human population increase in number. Population levels are driven by temperature, not levels driving temperature; they have it exactly back to front.
