Today I found a very interesting map in the WWW, how Earth will look like, when average temperatures rise about 4 degrees Celsius or 7.4 degrees Fahrenheit. Let’s think big (theoretically) for a moment:
In the future cities and agricultural zones will be located in Canada, Alaska, Siberia, West Greenland and West Antarctica. Only a little bit remains in West Africa and West Australia. The arctic passage will be the most important trade route. Todays tropical and temperate zones will change to deserts: South Europe and South America will be deserts, USA, China and India will also be deserts, the Alps and other mountain regions will be ice free. Northern Europe, England and Russia will be the last remains of the historically relevant political and military powers. Raising superpowers like China and India will vanish as fast as they came. Canada will obviously not survive as a nation and will become somehow ‚New America‘.
For anyone who reads this map it becomes very fast completely clear, why India and China are strengthening their activities in space exploration, nuclear power and antarctic research. It also becomes clear why Russia is currently arming and pile up nuclear weapons as fast as they can. This behavior is very rational from the point of view of such a climatic scenario in some decades.
