NASA Study: Human Influence on Global Droughts Goes Back 100 Years

Caption

For the first time, scientists at NASA GISS have linked human activities with patterns of drought around the world. Getting clues from tree ring atlases, historical rain and temperature measurements, and modern satellite-based soil moisture measurements, the researchers found the data "fingerprint" showing that greenhouse gases were influencing drought risk as far back as the early 1900's.
