Hydrological Implications of Rapid Global Warming

Researchers studying a rapid global warming event, around 56 million years ago, have shown evidence of major changes in the intensity of rainfall and flood events.  The findings indicate some of the likely implications should current trends of rising carbon dioxide and global warming continue.

It follows much discussion on the nature of global change in a warmer 21st Century at the COP23 Climate Negotiations in Bonn last week.

The new research, submitted to Climate of the Past Discussions, led by a team at the University of Birmingham, and involving multiple UK institutions and the British Geological Survey, sought to address this question using records from a major warming event in the Earth's past.

The rapid global warming event, ~56 million years ago, known as the "Paleocene Eocene Thermal Maximum" or PETM has provided such insights.
