MWP I take to be the Medieval Warm Period. Not sure what you mean by RWP.Sorry, I don't agree with you. The scenarios you propose didn't happen in the MWP or RWP so I see no reason why they would happen now.
The MWP at least is within the Holocene, hence part of our current period of climate stability.
Bracket the oceans for the moment. Something like 90% of excess global warming heat goes into the oceans, but most of the remaining 10% goes into the atmosphere.Oceans do have lag periods and enertia but once the heat goes in there are few ways to get it out again. Besides, oceans have their own regulating feedbacks, especially at the equator where most of the energy comes in.
That is enough to cause changes to the tipping points, described above. The 10% or less is sufficient to greatly reduce the Arctic ice (), threaten the Amazon rainforest, and cause melting of methane in the permafrost. None of this is controversial.
So granted what you say about the oceans, and I agree with you about the feedbacks etc, but they do not absorb all of the excess heat.
Well, maybe so. I would like to think so. Honestly.I think you have been sold a scary scenario that has little resemblance to reality.
I am not a climate scientist. I have advanced degrees in physics, but they are not directly relevant.
But, the large majority of climate scientists are convinced that we are going to a Very Bad Place, so to speak.
These are scientists, for chrissakes, and at recent conferences etc, they trade notes about shrinks, and how to sleep at night, etc. This is not normal behavior.
Call it all some kind of mass derangement phenomenon, if you wish. But it makes a lot more sense to suppose that it's what they know that makes it hard for them to sleep at night.
