A game where you are president of the European Nations. You must tackle climate change and stay popular enough with the voters to remain in office.
Another game about helping the community reach some specific climate goals. You have to create a climate plan to reduce greenhouse gas emissions by a certain percentage in a certain time frame. Your plans can include setting up alternative energy sources, reducing human consumption etc.
Sceptics have long argued that there are other explanations for climate change other than man-made CO2 and here we look at some of the arguments put forward by those who believe that global warming is all a hoax.
This title may come as a bit of a surprise, so too might the fact that the warmest year recorded globally was not in 2008 or 2007, but in 1998. But it is true.
What are some of the reasons why "climate sceptics" dispute the evidence that human activities are bringing potentially dangerous changes to the Earth's climate, ant their counter-arguments?
