There are many who fear that the sea may very well devour Kochi, within 25 years
Rising sea levels are a big concern to those living in the coastal areas. Global Warming theorists say that 1.5 meters of coast will be devoured by the sea, if the rise is 1 mm. By 2030, the rise will be 72 mm more and 108 meters will be devoured by the sea. A bitter truth ?
The cold winds from the ocean determines both Kala Varsha ( The S W Monsoon ) and the Thula Varsha ( the North East ) Monsoons.
If the wind speed is 12 kt, then the intensity of the Kala Varsha or the South West Monsoon will be less than half ! If more than 20, the Kala Varsha will be 150% and if it is more than 28 kt, the Kala Varsha will be 400%.
Climate Change has altered the speeds of Winds and we find that sometimes the SW Monsoon is intense and sometimes it is not !
Lands 8 meters below the sea level are under threat. Not only Kochi, but the coastal areas of Trichur, Calicut, Trivandrum etc are under threat. It is to be noted that some great complexes of Kerala, like Naval Academy of Tvm, the Naval Base of Kochi, the Cochin Airport, Kochi ePort and Tvm Airport are all under threat !
