Changing climate? The future of historical weather data

The globe has become about 0.6 C warmer during the last century, and 
climate models suggest a further increase in the range of 1-3.5 C. 
This is unprecedented in relation to millenium-scale climate 
reconstructions but a hardly noticeable change on a geological time-
scale. The major impact on human activities and the environment of 
this increase will probably come from extreme climate events. The 
question is thus what do we know about climate extremes, their 
natural variability, and how well do the climate models reproduce 
them. And what can we do to improve our knowledge? I will discuss 
these questions and present some work we are doing here in Lund.
