How much hotter will it get?

For the next two decades a warming of about 0.2°C per decade is projected. If nothing is done to reduce emissions; current climate models predict a global temperature increase of 1.4 – 5.8 degrees C within the next 100 years. Even if we cut greenhouse gas emissions today, scientists say some of the effects would continue because parts of the climate system - particularly large bodies of ice - can take hundreds of years to respond to changes in temperature.
