Precipitation Trends in Greenland During the Past Thirty Years

Tornado Trends over the past Thirty Years

Dr. Stanley Changnon has done extensive work in climatological studies that included tornado frequency. He studied these frequencies using tornado statistics across Illinois using data from storms that occurred between 1916 and 1980 (Changnon, 1982). He also guided work done at the Illinois State Water Survey on the significance of long-track tornadoes (Wilson and Morgan, 1971). One of the conc...

Trends in global monsoon area and precipitation over the past 30 years

[1] The analysis of the GPCP and CMAP datasets during the past 30 years (1979–2008) indicates that there are consistent increasing trends in both the global monsoon area (GMA) and the global monsoon total precipitation (GMP). This positive monsoon rainfall trend differs from previous studies that assumed a fixed global monsoon domain. Due to the increasing trends in both the GMA and GMP, a glob...

Natural variability of Greenland climate, vegetation, and ice volume during the past million years.

The response of the Greenland ice sheet to global warming is a source of concern notably because of its potential contribution to changes in the sea level. We demonstrated the natural vulnerability of the ice sheet by using pollen records from marine sediment off southwest Greenland that indicate important changes of the vegetation in Greenland over the past million years. The vegetation that d...
