2100: Climate Change Run Amok January 18, 2007

We all know that the Earth’s climate is changing… its actually in a perpetual state of change, thus the difficulty in predicting weather. However, advances in technology (namely a dramatic increase in computer processing power) have allowed scientists to look further into the future than ever before.

Using three different global climate models, each based on a mid-range forecast for greenhouse gas emissions, they computer the likely change in frequency of these extreme events during the period 2071-2100. The changes were then weighted to provide a single number between 0 and 19 for each of a series of grid squares encompassing the globe. A value of 0 equates to a 1 in 20 year, bad year average; a 19 mean 19 out of 20 years.


These series of images were composed illustrating that method to predict what the climate will be like in the future.

1. One more - January 18, 2007

I’d like this post more if at the end it linked to more than just New Scientist, but also to more sites listing what can be done on an individual level.
