Successful Predictions

According to this article from the Goddard Institute for Space Studies, a prediction made in the 1980's about the number of warmer seasons is now being observed around the world.

What we do know is that "normal" is slowly changing. The National Weather Service defines the warmest 30% of the seasons in the period of climatology as "warmer than normal" and the coldest 30% as "cooler than normal". In the 1980s it was predicted that, because of increasing human-made greenhouse gases, the percentage of "warmer than normal" seasons would increase to 60-70% by the beginning of the 21st century. That is just what has happened, as typically 60-70% of the meteorological stations around the world now report "warmer than normal" in any given season.
