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.[http://news.bbc.co.uk/2/hi/science/nature/3607335.stm Greenland's ice cap under threat], BBC News, 7 April 2004.

He was a co-ordinating Lead Author of the IPCC 2001 Third Assessment Report chapter 11 Changes in Sea Level [http://www.grida.no/climate/ipcc_tar/wg1/408.htm], 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[http://www.ipcc.ch/publications_and_data/ar4/wg1/en/ch5.html Chapter 5: Observations: Oceanic Climate Change and Sea Level], IPCC Fourth Assessment Report, 2007, Intergovernmental Panel on Climate Change.

Accessed July 29, 2011 . IPCC was a co-recipient (with Al Gore) of the 2007 Nobel Peace Prize for its work on climate change.[http://www.innovations-report.com/html/reports/earth_sciences/report-92886.html Scientists from the National Centre for Atmospheric Science Share in the Nobel Peace Prize], Innovations Report, October 16, 2007.

In 2010 Jonathan Gregory was awarded an Advanced [delete: Fellowship] Grant by the European Research Council to carry out research on sea level change.[http://www.metoffice.gov.uk/research/people/jonathan-gregory Jonathan Gregory, researcher profile], Met Office.

Accessed June 18, 2011 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.
