[holding answer 13 June 2008]: An evaluation of the implications of such an increase in global temperatures on provisions of food and water and flooding, can be found in the Fourth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC). This is available online.

To ask the Secretary of State for Environment, Food and Rural Affairs what research he has assessed on the likely level of stabilisation of global temperatures in relation to pre-industrial mean temperatures; what estimate he has made of the likely range of stabilisation temperatures; and what steps he plans to take to reduce the probability of stabilisation at the upper end of the temperature range.

Our assessment of future climate change comes from the Intergovernmental Panel on Climate Change’s (IPCC) 2007 Fourth Assessment Report (AR4). Warming over this century will be dependent on future human emissions of greenhouse gases.
