Birds Dissapear Due to Global Warming

The global warming has not spared even the birds and many other species too. So well, what difference does it make if the birds are there or not??? Well, to have a balanced ecosystem we need to have all the species to be there, and birds are one among them. We might not see a direct relation between their existence and our survival, but in reality there is.

Chennai, till recently home for sparrows, has seen the bird fast disappearing from the metro, apparently due to global warming as the city has witnessed a significant rise in temperature over the past century. Read on below to find more.

Data collected by the Regional Meteorological Office (RMC) here has revealed that from 1906 to 2008 there was a 'significant rise' in the average temperature in the city during summer.

The centre analysed weather data in the months of March, April, May and June. The temperature variation chart showed an increase of 1.8 degrees Celsius in the mean temperature in March -- meaning that the average temperature of 32.2 degrees Celsius in March 1906 had risen to 34 degrees Celsius at present.

The changing pattern of Chennai's weather assumes significance as a recent survey by an NGO found that the sparrows, which existed in large numbers in the city about 20 years back, had totally vanished due to the rising temperature.

Met officials said the mean temperature in April has risen from 34.1 degrees Celsius to 35.6 degrees Celsius over the past 10 decades, a rise of 1.5 degrees Celsius. Mean temperatures in May and June remained constant at about 36-37 degrees Celsius.
