Jonathan M. Gregory is a climate modeller working on mechanisms of global and large-scale change in climate and sea level on multidecadal and longer timescales. He is currently a senior scientist in the Climate Division of NERC's National Centre for Atmospheric Science (NCAS-Climate), located in the Department of Meteorology at the University of Reading, and a Met Office Science Fellow in [delete: the climate-change group] climate change at the Hadley Centre.

A 2004 study, led by Gregory and published in the journal Nature, predicted that [delete: run-away melting of the Greenland ice sheet could start within 50 years] the Greenland ice sheet is likely to eliminated as a consequence of global warming, resulting in [delete: its total meltdown over the next 1000 years and] a rise in global sea-levels by 7 meters over the next 1000 years or more.[1][2]

He was a co-ordinating Lead Author of the IPCC 2001 Third Assessment Report chapter 11 Changes in Sea Level [1], and a contributing author to the [delete: SAR chapter] sea level chapter in the IPCC Second Assessment Report. Gregory was also a [delete: co-] Lead Author of the IPCC 2007 Fourth Assessment Report chapter 5 Observations: Oceanic Climate Change and Sea Level[3] and chapter 10 Global Climate Projections[4]. IPCC was a co-recipient (with Al Gore) of the 2007 Nobel Peace Prize for its work on climate change.[5]

In 2010 Jonathan Gregory was awarded an Advanced [delete: Fellowship] Grant by the European Research Council to carry out research on sea level change.[6][7] In addition to sea level change, Gregory has worked in recent years on climate sensitivity and predicted changes in the Atlantic meridional overturning circulation, among other subjects.
