New NASA Data Show Brazil's Drought Deeper than Thought

New satellite data shows Brazil's drought is worse than previously thought, with the southeast losing 56 trillion liters of water in each of the past three years - more than enough to fill Lake Tahoe, a NASA scientist said on Friday.

The country's most severe drought in 35 years has also caused the Brazil's larger and less-populated northeast to lose 49 trillion liters of water each year over three years compared with normal levels, said NASA hydrologist Augusto Getirana.

Brazilians are well aware of the drought due to water rationing, power blackouts and empty reservoirs in parts of the country but this is the first study to document exactly how much water has disappeared from aquifers and reservoirs, Getirana said.

"It is much larger than I imagined," Getirana told the Thomson Reuters Foundation.  "With climate change, this is going to happen more and more often."
