Special Report on Emission Scenarios (SRES) 1 January 2014
The greatest source of uncertainty for anyone trying to predict how the climate will change is us. How will we behave in the future? Will we take the issue seriously and rapidly cut our emissions of greenhouse gases? Or will it be business as usual? There are a number of Emission Scenarios, which have been modelled to try and understand this. This section has been updated to include the new AR5 scenarios.
Stern Review: Economics of Climate Change 1 January 2010
The IPCC received a Nobel Peace Prize in 2007, which is a strong recognition of their work for humanity. You will now find that every political leader in the world knows that climate change is happening. Some of them may be paying lip service to the issue but they know it is important. One of the key things that convinced politicians was an economic paper: the Stern Review on the Economics of Climate Change. The conclusions of this paper were that climate change will cost between 5% and 20% of global GDP(Gross Domestic Product), each year (now and forever), if we don’t do anything about it. This compares to a cost of 1% of global GDP to do something about it if we start now. There is nothing quite like hitting our leaders in the wallet to persuade them to start taking it seriously!
