Humans have been causing droughts for 100 years
Today’s Video of the Day from NASA reveals that human activities were affecting global drought patterns as far back as the year 1900.
Researchers at NASA’s Goddard Institute for Space Studies (GISS) combined observational data such as precipitation with data found in tree rings to explore the climate response to greenhouse gases.
The study has produced the first historical evidence which links human-generated emissions to drought risk at near-global scales.
