NASA’s Scientific Visualisation Studio has some cool information on their site, but two ones I found today were of particular interest.

The first is an animation based on the output of the best of our current climate models, showing what would have happened if we had not enacted the Montréal Protocol banning the emission of CFCs into the atmosphere. The period covered includes actual data collected since 1978 and modelled data from 2009 forward to 2065, showing a side-by-side view of what is happening on the left, and what would have happened without the treaty on the right. Have a look here.

The second animation show the changing extend of Arctic sea ice based on actual satellite observations since 1979. It’s frightening how much it has changed in the last 30 years. That animation can be viewed here.
