With the United Nations climate change conference in Copenhagen looming at the beginning of December, the Science Museum in London has opened a new exhibition called PROVE IT! which runs until January 2010.
Visitors will be able to find out why climate change is happening and what the world is planning to do to combat it. PROVE IT! will also emphasize the importance of the Copenhagen talks to man’s future.
On October 22nd, the opening day of the exhibition, the UK government published a new map of the world. It shows what the world will look like after an average 4 degrees Centigrade global rise in temperatures, something that could happen as early as 2060 if there is no binding agreement to cut carbon emissions.
The map was produced by the British Meteorological Office’s Hadley Centre, which keeps track of global temperatures and produces the latest climate predictions based on its state-of-the-art climate models. Its latest map shows that the 4C rise in temperatures won’t be spread evenly across the world. Temperatures will increase more in higher latitudes such as the Arctic. The average land temperature will rise by 5.5C, reducing yields for all major cereal crops in every single major production area. Supplies of fresh, potable water would also be reduced and the oceans would absorb 40% less carbon than they do now.
The map was launched by David Miliband, the British Foreign Secretary and his brother Ed Miliband, who is the Energy and Climate Change secretary. This high-profile launch indicates that the British government is going all out to persuade the world that the Copenhagen talks are the last opportunity to protect us all from this 4C global rise in temperatures.
