I only doubt the contribution man has made to it and therefore man's ability to halt it.
this is one of the classic smoke screen arguments from Exxon sponsored 'scientists'. There's an awful lot of science behind this that I'm really not going to attempt to type out here, but going back to my slighty feeble home heating anaology, if you keep burning lots of fuel, the house gets warmer. What else could it do. 1degC in the atmosphere is equivalent to all the energy being generated around the world - that's why the weather patterns are larger and more extreme, lots of extra energy. Article below is quite good

When I look at the efforts made in countries like ours and then work in the USA where I see everyone is driving around in V8's and V6's it makes a mockery of our efforts. China continues with it's coal fired power stations as in USA, all of them producing cheap electricity putting UK and the rest of the world at a financial disadvantage.
this is one of the most disheartening things about the current picture, but, if our governments had taken more notice sooner, we wouldn't be so in the **** with energy now. We are lucky in that we have very good wind resources, and on-shore wind is the cheapest form of energy production. The great thing about most renewable energy sources are that they are relatively easy, quick, and cheap to build. We could easily be a net exporter of energy to Europe and earn some good money for the UK economy, as well as giving our own businesses a cost advantage - a bit like Iceland, the home of Aluminium smelting because of cheap thermal energy. I also believe you can't lecture the likes of China without sorting your own house out.
This also brings me back to an earlier point about politics, with the likes of Edwina Curry making comments about 'why would we make things ourselves if it's cheaper from abroad', well the environmentalists have long argued that purchase price is not the whole picture. We should be applying taxation to recognise disposal costs and CO2 emmissions, because the true cost of a product is not just what it takes to make it, but it's impact on the planet as well. But politicians wouldn't want to put prices up would they. Platics is a classic, it's now so widely spread through the entire planet on land and sea the cost of cleaning it up is astronomical / basically impossible
there are varying ideas of what 1.5 or 2degC means for the planet, but this seems a resonable version ie not an extremist viewpoint. What is worrying is the permafrost is starting to melt in polar regions, worrying because it releases shed loads of methane, 58 times worse than CO2. Go too far and we risk a runaway heating of the planet that will be out of our control. Currently I'm trying tp persuade the wife to move somewhere colder, like Iceland
