The data comes from Nasa spacecraft that can detect changes in gravity caused by water as it cycles between the sea, the atmosphere and the land.

Experts stress no firm conclusions should be drawn from the short study.

Professor Jay Famiglietti from the University of California-Irvine said much longer times series were needed to detect real trends and any signal that might indicate a significant shift in climate.

"There are natural climate variations, the natural ups and downs," he explained.
