One of the worst case scenario 'business as usual', which assumes a 500% increase in the use of coal is now considered very unlikely say researchers. Such a model predicts that by 2100, we would see an increase of up to 6C in global temperatures resulting in severe impacts.
Instead, based on current trends, it is stated that by 2100 there is more likely to be an increase of approximately 3C in global temperatures. Many experts state that these lower temperatures are not guaranteed and are based on current commitments made by policies countries have signed up to. Additionally, it is beginning to emerge that the models used to predict these temperatures a re more sensitive to CO2 than originally believed.
So despite the positive impacts certain processes appear to be making on the future of our climate, all is not certain quite yet.
