Event Description 

The warming of mean temperatures is well established, but there is much more to climate change. Is the weather becoming more stormy? Are there more droughts? What is happening to temperature extremes? These have been the subject of speculation, largely unmoored from data. I will present results of statistical studies of historic trends in the variance of hourly rainfall (a proxy for storminess), drought, and the frequency of all-time record high and low temperatures. These are mostly based on data from the 48 contiguous United States, where extensive data exist, but the temperature record data are world-wide. World averages conceal large, and unexpected, regional differences.
