Summary:
A leading U.K. climate scientist has presented new research findings on the increasing potential for a 4 degrees Celsius rise in global temperatures if the current high emissions of greenhouse gases continue. "If greenhouse emissions are not cut soon, then we could see major climate changes within our own lifetimes," said Dr. Richard Betts, Head of Climate Impacts at the Met Office Hadley Centre.

The conference at Oxford University is the first to consider the global consequences of climate change beyond 2 degrees Celsius, and is jointly sponsored by University’s Environmental Change Institute, the Tyndall Centre for Climate Change Research and the Met Office Hadley Centre.

Speaking at the international conference called ‘4 degrees and beyond’ at Oxford University, Dr Richard Betts, Head of Climate Impacts at the Met Office Hadley Centre, described the possibility of a 4 degree warming happening ‘before the end of the century’. He added that a scenario of very intensive fossil fuel burning could bring this forward by 20 years.

Conference convenor Dr Mark New, from the Oxford University School of Geography and the Environment, and the Tyndall Centre, said: "Since the late 1990s, greenhouse gas emissions have increased at close to the most extreme IPCC scenarios, meaning that rates of warming will be faster than most people expect. The conference will review the best science on the consequences of these large climate changes and what we can do about it."

In this presentation Dr Betts warned that 4 degrees of warming could have extreme regional implications along with major changes in rainfall. He said: "If greenhouse emissions are not cut soon, then we could see major climate changes within our own lifetimes."

Other speakers are Professor John Schellnhuber, Director of the Potsdam Institute for Climate Impact Research, on 4 degrees warming and the potential for tipping points; Professor Yadvinder Mahli, from Oxford University’s Environmental Change Institute, on the impact on tropical forests; Dr Philip Thornton, International Livestock Research Institute, Nairobi, on sub-Saharan agriculture; Dr Pier Vellinga, from Wageningen University, on sea-level rise; and Professor Kevin Anderson, Director of the Tyndall Centre for Climate Change Research, on global emission pathways.

The Environmental Change Institute (ECI) at Oxford University focuses on environmental change across the natural and social sciences with an orientation to applied and public policy. ECI plays a leading role in three of the UK Government's main climate research initiatives: the UK Climate Impacts Programme, the Tyndall Centre for Climate Change Research, and the UK Energy Research Centre.

Topics from over 50 other conference research papers included: food and water security, vulnerable populations, human health, migration, wild fires, sea level rise, wildlife conservation, and ecosystem services. Regional case studies will include Amazonia, Australia, Bangladesh, Brazil, Ethiopia, Finland, Mauritius, Siberia, Vietnam, and the monsoon region.
