Although being a global issue, Climate Change effects by country could be very different.
According to the scenarios obtained from climate models in the IPCC 4th Assessment Report, the temperature rise will be more significant in the higher latitudes of the Northern hemisphere, especially in the North Pole.
Climate Change effects by country are quite different regarding the future precipitation behaviour. There would be a rainfall increment in higher latitudes in both hemispheres in the summer months. Instead, precipitation will decrease in areas already facing water shortages.
