Just for a change....

I don't think it matters, all of them and most of the public had this one licked 30 years ago. This has received so much coverage I assumed it wasn't a genuine question so apologies if NormanS has somehow missed the messaging.

Archimedes had it licked more tha 30 years ago! The ice at the North Pole is floatinhg so if/when it melts it will not affect sea level. The much greater volume of ice on Greenland and Antartica will raise sea levels considerably along with thermal expansion.

Further, melting the sea ice will decrease the albedo (ice is white, seawater is (more or less) black)! So less of the sun's radiation is reflected back into space. Therefore, the Arctic Ocean will become warmer, with major effects on oceanic circulation. The immediate effects might well be to plunge Europe into an ice age!

The effects of global warming are by no means always obvious. But oceanic circulation is the major way by which heat is transferred between the equator and the poles; water carries far more heat than air.

I forget the exact reasoning, but melting sea ice does have a small effect on sea-level, as well. But it is small.

A number of folk on this thread are expecting the UK to become more like northern Canada due to the future effects of climate change. While they seem to be focussing on snow and ice as a likely (and, by inference, unpleasant) outcome for the UK, the reality will be much worse. Vast tracts of the Canadian north are inhabited by immeasureable hordes of midges, mosquitoes, black flies, and deer and moose flies. Each of these species specialize in collecting blood from different places across the human anatomy and all seem to enjoy flying into open mouths and nostrils which tends to make breathing a challenge. It is no coincidence that the human population density in the north of Canada is about 1 person per 3 sq.km. and none of them remain stationary any longer than necessary.

Will We all be migrating back to Africa were the troublesome migrants are coming from now😂

Unlikely, it’ll be 50C in most of Africa by that point so while there may not be flies, there probably won’t be humans either. We’ll all be fighting over a small patch of inhabitable land somewhere in France.

Sounds to me like Skye in August...!

Something to do with the ice being fresh water and the sea being salty. Must fit the plimsoll line? Or freezing water expanding so it floats?
