“Losing the remaining Arctic sea ice and its ability to reflect incoming solar energy back to space would be equivalent to adding one trillion tons of CO2 to the atmosphere, on top of the 2.4 trillion tons emitted since the Industrial Age, according to current and former researchers from Scripps Institution of Oceanography at the University of California San Diego.”
“At current rates, this roughly equates to 25 years of global CO2 emissions.”
We’re actually heading for a 10C global mean temperature increase in the coming decade or two. Probably much sooner.
“The analysis of climate sensitivity by David Wasdell is very important. I have been through it with him several times and am convinced of its validity. I mentioned it in “A Farewell to Ice”. The point is that here is a big difference between the short term sensitivity, which is used to calculate warming over a few years, and the long term sensitivity which represents how much warming the earth is going to be subjected to if you don’t add more CO2 but let the effects of the present levels work their way fully through the climate system. Short term sensitivity is 2-4.5 C, but long term is more like 10C. The crime of IPCC and other modelling outfits is that they are aware of this difference between short and long term, but still use the short term value even when they are doing hand-waving studies of what is going to happen over the next century or two. In fact it;’s not just the case that the magic 1.5C or 2C warming is already “baked in” to the global system – in fact the baked in figure is more like 4-5 C. Hence the vital need for carbon drawdown. Best wishes Peter Wadhams”

John Doyle mentioned the term Wet Bulb, I have covered that boiling issue here’ Wet Bulb Temperature Soon to Become Leading Cause of Death
We discussed the work of Dr Natalia Shakova, I highly recommend this interview with this great scientist; Methane Hydrates extended Interview Extracts With Natalia Shakhova
We discussed the issue that even Shell Petroleum admits that 5C is baked in, the evidence is embedded here; Oil Giants admit to a 5C Temperature Increase being baked in but no one else will!

“Looking further forward to when all the methane will be released from under the World’s thawing permafrost Sir David warns us to expect not a few degrees of warming but as much as 20 degrees over the next few centuries.” Few Centuries, where have I heard that before ?
