    When deciding how much to cut global greenhouse gas emissions, governments look at scientists’ estimates of the possible impacts of different amounts of global temperature rise. Policy-makers examine the ways climate change could affect our food and water resources, our health and our homes and buildings, and assess the associated risks as far as is possible. This helps them to weigh up the costs of emissions-cutting measures against the costs of the alternative approach of adapting to the impacts of climate change – the aim is to strike a sensible balance between the two.
