Global warming model. Computer-generated map of the world showing the effect of carbon dioxide (CO2) on global temperatures. The map shows how much warmer surface air temperatures would be in northern winter (December to February) if the man- made CO2 load in the atmosphere were twice the present value. Temperature increases are colour- coded from pale yellow (0-2 Celsius) to red (8-12 Celsius). The model clearly predicts a dramatic warming of northern hemisphere winters,with the largest warming seen in western USA & Canada,northern Eurasia and in the Arctic circle. This is a result of the so-called 'Greenhouse Effect' | |
