Climate change: The evidence

Our world is getting warmer. Over the last 100 years the average global surface temperature has risen by about 0.74C.

This seemingly small rise has already had a significant effect on our planet.

For example, the record books have had to be re-written recently, as 11 of the 12 hottest years recorded so far have all taken place since 1995.

It is "very likely" that the rising level of carbon dioxide in the atmosphere is the cause of climate change, according to the Intergovernmental Panel on Climate Change (IPCC).

Human activities, such as burning fossil fuels, are the primary source behind this increase.
