You've been watching too many reruns of the Day After Tomorrow and 2012. Gear down the DOOMmobile. Per the Fourth Assessment Report (AR4) of the United Nations Intergovernmental Panel on Climate Change (IPCC):
* Low range: best estimate temperature rise of 1.8 °C with a likely range of 1.1 to 2.9 °C (3.2 °F with a likely range of 2.0 to 5.2 °F) resulting in a sea level rise likely range [18 to 38 cm] (7 to 15 inches)
* High range: best estimate temperature rise of 4.0 °C with a likely range of 2.4 to 6.4 °C (7.2 °F with a likely range of 4.3 to 11.5 °F) resulting in a sea level rise likely range [26 to 59 cm] (10 to 23 inches)
Do you REALLY think that a sea level increase of 7 - 23 inches is going to result in "most of the world's great cities will be drowned...". Really? Really? Take a look at the elevation of some world cities: http://en.wikipedia.org/wiki/List_of_cities_by_elevation or http://www.pmiusa.biz/pdf/US%20City%20Elevation%20Chart.pdf . For your claim to be true "most of the world's great cities" would need an elevation of less than 1 meter..actually more like 0.5 meters. And that's for the worst case scenario per the IPCC.
This doomer hysteria is so old.
