Scientists used 22 climate models to determine exactly how much summer temperatures would be.

Scientists have concluded that by the end of the 21st century, temperatures will be "very severe and we have not seen them before."

The researchers concluded that developing countries and small islands will be hardest hit by this heat, which will rise monthly.

The researchers said the increase in temperature was directly related to the rise in global greenhouse gas emissions.

Greenhouse gases exist in the atmosphere and are capable of absorbing the infrared radiation lost by the Earth; reducing heat release into space, which helps to increase the planet's heat; thus contributing to global warming and global warming.
