I've been hearing a lot of news lately about global warming. What is it all about?

Global warming is the long-term increase in the Earth's average temperature due to human activity, such as burning fossil fuels and deforestation. The effects of global warming are already being felt around the world, including rising sea levels, more extreme weather events, melting glaciers and ice caps, and changes to ecosystems. Scientists predict that if we continue to burn fossil fuels at current rates, temperatures could rise by an additional 2°C (3.6°F) by the end of this century. This would have devastating consequences for the planet and its inhabitants.
