Talk:1379: 4.5 Degrees

Scary thoughts there... Kynde (talk) 05:11, 9 June 2014 (UTC)

I imagine the Earth's axial tilt wouldn't change even if the temperature changed by +2 IAU. So, would palm trees survive the extreme day/night lengths at the poles? 103.22.201.239 05:31, 9 June 2014 (UTC) P.S. Also, wouldn't the North Pole be underwater, so incapable of supporting palm trees? Also, regarding the IAU, is it a reference to the IAU that named an asteroid after Randall?

"While it says it's "probably no big deal," this is probably a joke, because even half of an Ice Age would be a lot of ice." The article has it wrong. It's a 2 degree increase, not decrease. Ice would melt. 108.162.238.134 07:33, 9 June 2014 (UTC)

To prevent global warming, act yesterday! ... or, well, since we already failed to do it, maybe ... just maybe ... we should invest some resources to ADAPTING to the change. Because the USSR communist party wanted to command “wind and rain” and how it worked? ... of course, we SHOULD be trying to lower the CO2 emissions ... not like Germany, which replaced it's nuclear power plants with coal ones ... -- Hkmaly (talk) 10:03, 9 June 2014 (UTC)

Well, this seems like a topic that could generate heated comments. 108.162.208.9 10:09, 9 June 2014 (UTC)

Would anyone care to comment on the +200 meter sea rise? I googled "how much would sea level rise" a bit, and I seem to bump into 60 to 70 meters repeatedly for all glaciers melting. I found nothing direct from IPCC. I wonder if Randall really has another view on this.

I hope the explanation isn't that he made a meter/feet mistake. 103.22.201.239 13:04, 9 June 2014 (UTC)

I would assert that he rounded for a clean read for a relative scale. Also, the '+' denotes the likelihood of a larger actual amount.

60 meters is indeed the amount the sea would rise if all the glacial ice melted. However, that figure presumably does not take into account have much the sea would rise by expansion due to the increased heat. That is, after all, the main reason for rising sea levels today. So I would guess that the +200 figure is the 60 meters of added water from glacial ice plus the amount it would rise due to warming and expanding. Calebxy (talk)

While that's possible, and desalination of water can also cause it to expand (sea water is more dense than fresh), we shouldn't try to justify the numbers if they are incorrect. If we can find some reliable data to suggest the rise would be 200 ft instead of 200m, we should include that. Or at least include a range of estimates from reliable sources. 108.162.238.134 15:42, 9 June 2014 (UTC)
