Global warming, the idea that the world is getting hotter, is a story which is often in the news in one form or another. Richard Black There's really a wealth of evidence that the world is getting warmer. First of all we have actual climate research stations where temperature is recorded. Some of those have been in existence for over a hundred years, and they show overall that things are getting warmer. We're seeing for example the melting of sea ice, particularly at the Arctic, also at the Antarctic. We see for example differences in the growth rings of trees, we see that trees are now growing faster - that's dependent on temperature. We're seeing differences in the growing season, differences in where birds and insects live, and that's really all because our climate is changing.
