IPCC – Fourth Assessment Report (AR4) 1 January 2010
The core group of people that are looking into the climate change problem are the Intergovernmental Panel on Climate Change (IPCC). You can see their latest findings at the IPCC website. Their Fourth Assessment Report (AR4) was published in 2007. This is the consensus of all of the world’s leading climate scientists. Its findings are quite worrying, especially how much change has accelerated more than they predicted in the previous report. However, they do make clear that we can make a difference (i.e. mitigate the problem) if we act now. There is a lot of information on their website, you will probably want to start by reading the Summary for Policymakers documents in AR4, starting with “The Physical Science Basis”.

Stern Review: Economics of Climate Change
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!
