Colloquium: How Do We Know That Human Activities Have Influenced Global Climate?

Estimates of the amount of atmospheric water vapor over oceans from the satellite-based Special Sensor Microwave Imager. Results are for August 28, 2005 (top panel) and August 29, 2005 (bottom panel). Locations with high atmospheric moisture content are denoted by red and white colors. The highest water vapor values are associated with typhoons Talim and Nabi in the Pacific and with Hurricane Katrina in the Gulf of Mexico.
