How Climate change and global warming form Hurricane and its disaster to the Economy.

Hurricane  formed  when warm humid air rises from the ocean.Convergent winds force the warm air into the atmosphere,where it releases latent heat as it condenses into clouds and rain.The exchange of heat from the surface creates a pattern of wind that spirals up around the eyes of the storm and hurricane grows,powered by ocean's heat and evaporating water.Hurricanes are assigned with different names depending upon the area where they have occurred.For example Hurricane storms are are called hurricanes, if  they start over caribbean sea,the northeast pacific ocean and north atlantic ocean,where as storm are called tropical cyclones ,if they occur in the Indian ocean or Australia.And in east africa the called cyclones always start at Reunion and Mauritius Islands[border of warm and cold water].In China they called   typhoons.A storm is classified as a hurricane when the speed  of wind reaches 74 mile [119 km]per hour.Hurricane storms usually starts over warm sea[ more greenhouse gases] near equator and are accompanied by fierce winds,flash,flood,mudslide and huge waves.Keep in mind that OCEAN act as "buffer" or absorber of carbon dioxide.The more we add it to the atmosphere  the more the ocean warm up.So as result more EXTREMES weather occur.Example of recent powerful hurricane are ,Hurricane katrina on August 29,2005 which struck the United states ,causing death of more than 1,800 people and property damage worth $81 billion. And  Hurricane sandy.And more Hurricanes are  expecting  to hit the world if we does not reduce global carbon dioxide concentration[CO2].Let us Plant more trees[carbon absobers] ,use clean energy like ,solar power ,wind and other green energy power.
