This report examines the potential impact of future climate change for the food security of vulnerable groups in the UK. Food security3 is a critical element of societal stability and prosperity, and its attainment is potentially influenced by climate in many ways. Globally, we are already committed to some climate change from emissions currently in the atmospheric-oceanic systems and looking ahead to the 2090s, assuming continuation of current emission trajectories, we can expect global warming of between 2.8 and 4 C (Solomon et al., 2007). Changes in climate at the global level over the coming century include (Solomon et al., 2007): very likely increase in frequency of heat waves and heavy precipitation events with a reduction in cold episodes and the diurnal temperature range. Tropical cyclones will increase in intensity and precipitation generally is very likely to increase at higher latitudes coupled with likely decreases in precipitation across subtropical regions. The chance of drought will increase in mid-continental areas, and sea level rise is expected. All of these changes will have implications for food production, infrastructure, trade and consumption. This commitment to certain levels of warming, and the potential for much greater warming in the future, means it is vital to consider localised impacts and think about adaptation to climate change as well as mitigation.
