According to the UK's Hadley Centre and University of East Anglia, 2007 is the seventh warmest year on record, despite the cooling influence of La Nina. So what is La Nina? Take a look...

...also, the Met Office has some good links from their climate change page that are worth a look too.

Savanna Ecosystems

Savannas are extensive tropical grassland areas that cover more than 10 million square kilometres of the Earth. The largest expanses are found in Africa (nearly 4 million square kilometres), South America, and, to a lesser degree, Asia and Australia. The dominant vegetation in savannas is usually grasses, intercalated with shrubs and trees. In some cases, savannas evolve into other ecosystems.

Tackling Climate Change

At the UN climate convention meeting in Bali, discussions have taken place concerning possible solutions to climate change, including biofuels. But who is responsible, and who emits what? Also, what can be done to help reduce emissions in the UK? Could wind power be an option?

Climate Change

What are the consequences of global warming and how do we know? Climate change will have a severe impact across the globe. However, according to the BBC, climate change targets are 'unreachable' , as it is unlikely that levels of greenhouse gases can be kept low enough to avoid a projected temperature rise of 2C. Despite the fact that many nations will fail their targets, it is thought that goals should made for developing countries to reduce their emissions.
