With imagined weather forecasts, United Nation recent initiative called 'weather reports from the future' predicted the disastrous climate change by 2050.
The United Nations has warned 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 publicising a UN climate summit, the Guardian reported.
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.
UN secretary general, Ban Ki-moon, said in a statement that climate change has been affecting the weather everywhere and it makes it more extreme and disturbs established patterns, which means more disasters.
Ki-moon has asked world leaders to make "bold pledges" to fight climate change at the meeting in New York. The summit is meant as a step towards a deal by almost 200 nations, due by the end of 2015, to slow global warming.
