Long description

This is a map of the world showing the mean average temperature change in different parts of the world between the years twenty-fifteen and twenty-nineteen, relative to a baseline from the years eighteen-fifty to nineteen hundred. The temperature change, given in degrees Celsius, is colour coded relative to the baseline as follows: dark blue is four degrees cooler, light blue is two degrees cooler, no colour is no change, orange is two degrees warmer, and red is four degrees warmer. The colours across the world are yellow to pale orange in the southern hemisphere, representing a mean temperature increase of 1 to 2 degrees Celsius relative to the baseline. Moving north, the colours change to darker shades of orange, indicting warming above two degrees, and become red around the Arctic regions, indicating three to four degrees warming. This shows that temperature rise has not been evenly distributed across the world; it has been greater in the northern hemisphere compared to the southern hemisphere, and has been greatest in the Arctic regions.
