The results of a new scientific assessment on the physical impacts of climate change for more than 20 countries show that if greenhouse gas emissions are left unchecked global temperatures will rise between 3-5°C this century. This could be accompanied by significant changes in rainfall patterns, leading in many cases to increased pressure on crop production, water stress and flood risks.
