Ensuring a Sustainable Future

Based on climate simulations we know that global warming is caused by human
activities that produce greenhouse gas emissions (mostly CO2). Figure 1 shows the results of climate simulations for a “business as usual” scenario, and for the case when the greenhouse gas emissions are greatly reduced. The validation of the models was the historical climate data set. Based on the validated models we know that the warming-up process will not slow down if we don’t reduce our CO2 emissions or extract enormous
amounts of CO2 from the atmosphere.
