Most studies predict a rise between 2 and 6 degrees by 2100, having impacts ranging from severe to catastrophic. One such model study is reported in the attached video. It may look a bit boring at first, but please put it on HD, notice the scale at the bottom and really focus on what happens to the planet with and without CO2 emission reductions.
This particular model shows a lot of warming especially on the poles and on the continents in general. How would you like to live in an Africa 8 degrees hotter than it is today? What do you think will happen to the ice at the poles with a full 16 degrees temperature rise? Scary thoughts…
At this stage, we all still hope that these models are overly pessimistic and perhaps over-estimate the greenhouse effect. But in any case, we cannot say that we have not been warned…
