Two degrees in all reality in my opinion will soon appear as wishful thinking. The Arctic is already at 10-12 deg C warmer and the Antarctic is also melting faster than scientists thought possible, with massive as yet invisible undercutting by warming sea water into the ice massif itself. But its not ‘how we feel’ as humans in a warmer environment it is the effect upon individual and cascading and interconnected feedback loops and weather systems and hard to believe they could be so sensitive! Each exacerbates the other. Already the jet stream is looping over and crossing the Arctic, also looping onto and below the Equator, this should not be happening! This all brings about a much changed situation and all for the worst, none of hundreds of points of consequence is a move for the better. We have lost sea ice, therefore turbulence increases, subsea permafrost releases increased methane and there are vast deposits that at the moment are relatively stationary of this most unwelcome visitor at 20-100 fold the potency of CO2 depending upon timescale.
It is shameful and sad that a distorted White House is heeding so easily the lobbying of the soon to be extinct coal and oil industries ie companies wanting to extract whatever profits remain to be made and contrary to the will and desire of the worlds population. The American Environmental Protection Agency, the EPA, with Scott Pruitt has been gutted and castrated, scientists dismissed or placed in menial or irrelevant job positions and no free exchange of information; the denial of the facts, of data. Even the term ‘climate change’ is banned. This is chaos and evil of the order of magnitude that would serve as storyline for a Marvel comic; theres no limit to where trump will get his claws into and wreck all good sense.
Last year ie 2017 dipped below the upwardly curving mean, so in all probability 2018 will see many horrible weather events.
All this will happen much quicker than most mainstream predictions want to forecast as ‘likely’. For instance what the IPCC forecasted as total loss of summer Arctic sea ice as 2080 is already here.

James Lovelocks book ‘Gaia’ as mentioned in I think page two here on my climate-change-briefing.com blog is a most valuable primer for the layman. If you can read it and understand and memorise it then you will be able to take part in many and most discussions re climate change. He discovered the gas DMS the product of oceanic plankton and which influences planetary cloud formation; a man of breadth as well as depth. His biography is a most fascinating read, originally self taught, naturally talented; NASA have utilised him as an independant scientist. Here below he tells us that with the loss of Arctic sea ice the absorption rate will escalate and heat the worlds oceans as much or more than all or any CO2 emissions. Ice in a sense was our ally, it reflected sunlight.
