On May 27, 2009, headlines across most national daily read about 200 people being dead in Bangladesh and eastern India with India alone accounting for 82 of those deaths. The reason behind the sudden catastrophe was not another terrorist attack but Cyclone AILA, a threat bigger than any terrorist organization can ever be. As per Associated Press, more than 2.3 million people have been affected by the cyclone. More than the human loss, large areas of crops have also been affected in both the countries. Many farmers have lost their rice just ready to be harvested.
Forest wardens in the Sunderbans fear that the flooding across the mangrove forests might have killed at least a dozen of the highly endangered Bengal Tigers. As per the last census, there were only 265 tigers left. Some tigers have sneaked into the nearby villages and are creating problems for the local residents.
And as the cyclone water would recede the death toll is only expected to rise due to spread of epidemics like cholera, diarrhoea etc.
However, majority of the people would look at those facts and say, “ Kya Farak Padta Hai”. This is just another cyclone, a natural tragedy and no one can do anything to prevent it. And this is exactly where one needs to understand that this is not a natural tragedy but an event which is created by humans and could have certainly been averted.
If you look at the basic physics of cyclones, it is very simple to understand. A storm gets its potential energy from the oceans and the warmer the ocean is, the more energy the storm should be able to draw in. Climate Scientist, Kerry Emanuel from MIT published a report stating that warming ocean temperatures are making hurricanes more powerful.
The data from 1855 to 2005 throws some very interesting results. If you look at the data during this period you can clearly see that the number of cyclones per year have doubled in that time from an average of 6 to an average of 14 over the past decade. And going forward, with increasing temperatures, scientists are estimating an average of at least 15 storms every year.
More importantly, globally, the areas of warmer oceans have nearly tripled in size since the beginning of the 20th century from roughly 17 million square miles to more than 46 million square miles. There has been an average of one additional cyclone for each 0.1 degree Celsius increase in sea surface temperature and one hurricane for each 0.2 degree Celsius rise.
The current average temperature of earth is around 14 degree Celsius and in the coming times it is expected to go up to 18 degree Celsius. And who is to be blamed for all that. Certainly not the nature alone. If we want, we can bring the temperature down and with it bring down the number of cyclones, hurricanes affecting us and ultimately bring down the number of so many innocent deaths around the world.
