As a science - climate change is not "done and dusted". It is an ever changing field and there are so many variables that often scientists can only make predictions that are based on best guesses. There is technical jargon for this including "limitations of methodology" or "assumptions" or "degree of correlation" but scientists operate within degrees of certainty. This makes the whole subject fascinating for me and it is impossible to second guess nature which has so many checks and internal balances that we know very little about and find difficulty in predicting accurately - like a medium range weather forecast. Weather and climate are different but that is for another post ..
I was fascinated to read in Nature News that a reduction in the amount of water vapour high in the Earth's atmosphere could be responsible for causing average global temperatures to flatten out over the past decade. This is despite ever-increasing greenhouse-gas emissions. It is important to focus on the "could be" i.e. this is a hypothesis not a proven fact as yet.
Check out the nitty-gritty of this fascinating article.
