Climate Change: 50 Years Past And Possible Futures

Summary:
A new NASA-funded study used a computer climate model to simulate the last 50 years of climate changes, projects warming over the next 50 years regardless of whether or not nations curb their greenhouse gas (GHG) emissions soon. If no emission reductions are made and they continue to increase at the current rate, global temperatures may increase by 1-2 Celsius (1.8-3.6 Fahrenheit). But if the growth rate of carbon dioxide does not exceed its current rate and if the growth of true air pollutants (things that are harmful to human health) is reversed, temperatures may rise by only 0.75C (1.35F).
