Video: UN Predicts Climate Hell in 2050 With Imagined Weather Forecasts

The United Nations is warning of floods, storms and searing heat from Arizona to Zambia within four decades, as part of a series of imagined weather forecasts released on Monday for a campaign publicizing a UN climate summit.

"Miami South Beach is under water," one forecaster says in a first edition of "weather reports from the future", a series set in 2050 and produced by companies including Japan's NHK, the US Weather Channel and ARD in Germany.

The UN World Meteorological Organization, which invited well-known television presenters to make videos to be issued before the summit on 23 September, said the scenarios were imaginary but realistic for a warming world.

A Zambian forecaster, for instance, describes a severe heatwave and an American presenter says: "The mega-droughtin Arizona has claimed another casualty."

Some, however, show extreme change.  One Bulgarian presenter shows a red map with temperatures of 50C (122F) – far above the temperature record for the country of 45.2C (113F) recorded in 1916.
