Climate change. A worldwide and interesting topic for discussion, but one of the challenges associated with it is presenting research data in a way the the general public will understand. Google have teamed up with the British government to add new layers to Google Earth that highlight how climate change could potentially affect the planet. One layer, developed with the Met Office Hadley Centre illustrates temperature modelling data for the next hundred years, while the British Antarctic Survey have produced a layer which shows how they measure climate change in that region of the world. More detail, and a video of British Prime Minister Gordon Brown talking about the initiative (well, more about the global economy) can be found on Google's LatLong blog.
