Over 150 scientists from 10 different countries are meeting in Denver, Colorado, to discuss rain and snow and how to measure them from space. Only once a year members of the Precipitation Measurement Missions (PMM) Science Team come together to discuss the science surrounding both the current Tropical Rainfall Measuring Mission (TRMM) and the upcoming Global Precipitation Measurement (GPM) mission that will launch in 2014.
One of the great challenges facing mankind in the 21st century is the threat of global climate change due to increased levels of carbon dioxide and other greenhouse gasses in the atmosphere. Is the threat real? Computer models that predict the future climate still differ in some very substantial ways with some models predicting little or no warming, while others predict temperature increases that would substantially alter our way of life.
