TS.C.3.1 Climate change will increasingly add pressure on terrestrial food production systems with every increment of warming . Some current global crop and livestock areas will become climatically unsuitable depending on the emissions scenario . Compared to 1.5℃ global warming level, 2ºC global warming level will even further negatively impact food production where current temperatures are already high as in lower latitudes . Increased and potentially concurrent climate extremes will increase simultaneous losses in major food-producing regions . The adverse effects of climate change on food production will become more severe when global temperatures rise by more than 2°C . At 3ºC or higher global warming levels, exposure to climate hazards will grow substantially , further stressing food production, notably in sub-Saharan Africa and South and South East Asia .
