Oct 13, 2014 Climate: sensitivity Royal Society The Royal Society is to hold a meeting on climate feedbacks at the start of December:
The response of Earth’s climate system to a perturbation depends on the sign and strength of several feedback processes. This meeting will present critical assessments of major feedbacks, including those (such as ice sheets and the carbon cycle) operating over long timescales. For each, their role in past and present climate change, and their expected future effects will be discussed.
Details here, including a detailed programme.

I hope they will post all the presentations and the text of the lectures on line - they will, won't they?
Now if those are actually going to be critical assessments, in the proper meaning of the word, we might well be onto something.
However, I'm still not planning to hold my breath.
I wonder if they will look at the 4C 'perturbation' that jolts global mean surface temperature every year? The climate system does not go haywire, shows no sign of tipping, and people, plants, and animals cope. So that's clearly not of interest.
I'm encouraged by their use of 'perturbation'. Too few people understand that the apprehensions about Catastrophic Warming are premised on so-far unprovoked positive feed-back mechanisms. If this topic gets a fair airing, it should be quite interesting.

Pessimists seem to see the wildly swinging paleo records as proof that small perturbations have large effects on a fragile planet so we need to stop poking it with our emissions. Optimists though see the same data as proof that the planetary climate can change without our help and so likely produces many natural micro-cycles of 0.6K/century or more within those natural macro-cycles. Alas in fact the ice core data tell us zero about climate change manmade or otherwise beyond confirming our biases. But unless and until the climateers can tell us convincingly what causes the cooling periods then they cannot pretend they have the heating periods nailed.
I'm shocked.
Stunned.
Flabbergasted.
After 30 years; they seem to have stopped abusing the term forcing and are adopting the more appropriate term perturbation.
Surely that can't be right.
'Tisn't what we would like to hear and see.
So soon after the latest AR and supposedly RoyalSociety is going to have a conversation? More like a propagandza lollypalooza by the bamboozlers.
I hope some scientists attend who force the presenters into making hard cold statements from the presenters for the everlasting joy of History. Piltdown climate man of the twentieth first century!
WTF !!
I thought the science was settled.
