New study links changes in global water cycle to higher temperatures

An international group of experts from across the globe sought to investigate how water levels may be affected by changing global temperatures and used reconstructions from the past to try and predict future movements. 

A study from the Past Global Changes Iso2k project team, including Professor Matthew Jones at the University of Nottingham, takes an important step toward reconstructing a global history of water over the past 2,000 years.

Using geologic and biologic evidence preserved in natural archives — including 759 different paleoclimate records from globally distributed corals, trees, ice, cave formations and sediments — the researchers showed that the global water cycle has changed during periods of higher and lower temperatures in the recent past.
