Climate change odds much worse than thought

ScienceDaily (May 20, 2009) — The most comprehensive modeling yet carried out on the likelihood of how much hotter the Earth's climate will get in this century shows that without rapid and massive action, the problem will be about twice as severe as previously estimated six years ago - and could be even worse than that. The study uses the MIT Integrated Global Systems Model, a detailed computer simulation of global economic activity and climate processes that has been developed and refined by the Joint Program on the Science and Policy of Global Change since the early 1990s. The new research involved 400 runs of the model with each run using slight variations in input parameters, selected so that each run has about an equal probability of being correct based on present observations and knowledge. Other research groups have estimated the probabilities of various outcomes, based on variations in the physical response of the climate system itself. But the MIT model is the only one that interactively includes detailed treatment of possible changes in human activities as well - such as the degree of economic growth, with its associated energy use, in different countries.

  1. Scary!

    The only way to get people to do something at this point is to give them a jolt!

    The results of such observations should be made public on a large scale and reach the decision-makers.

    I'm campaigning to prevent climate change and have made the following video to create awareness.

    Watch it and please RATE it :

    Also pass it on to other like-minded individuals who want to change the world for the better.
