If climate change is having an effect on Britain's weather, then our plants and animals will be among the first harbingers of it. Every year recorders make a note of tell-tale signs of spring in their area to help scientists build a picture of what is happening to our flora and fauna, and you can join in by going to naturescalendar.org.uk and help to contribute to Springwatch.
