NASA DATA MINING REVEALS A NEW HISTORY OF NATURAL DISASTERS
"NASA is using satellite data to paint a detailed global picture of the interplay among natural disasters, human activities and the rise of carbon dioxide in the Earth's atmosphere during the past 20 years.
According to a new scientific study that appears in the July issue of the journal Global Change Biology, scientists used satellite observations to estimate the amount of leafy cover worldwide and sudden decreases in 'greenness.' Greenness is a measure of the amount of chlorophyll in live plants.

"The new results come from a technique called 'data mining,' which sorts through a huge amount of satellite and scientific data to detect patterns and events that otherwise would have been overlooked,"
added Kumar, the principal investigator of a joint project of the University of Minnesota, California State University and NASA Ames to develop data-mining techniques to help Earth scientists discover changes in the global carbon cycle and climate system.
