National Capital has received scanty rainfall in the first four months of this year. As per the rainfall data of Indian Metrological Department (IMD), Delhi’s recorded rainfall is at deficient stage.
Environment scientists have raised alarm as the unusual rise in temperature has led to health hazards while also disturbing the available natural water resources. Considering the database of IMD, this year, total deficiency in rainfall from March to May 15 has been recorded at 21 per cent.
“Drastic changes have been measured in local weather this year. There is no rainfall in February, March , April and May month, and it is due to global climate change. The over industrialisation in city is also contributing to local climate change and the nearby States also comes under the loop of global warming effects,” said a scientist at Ministry of Earth Sciences (MoES).
According to the Weather wunderground.com website the average maximum temperature of May2015 oscillated between 38 degree Celsius and 40 degree Celsius. However this month, the maximum temperature has broken the record of past 22 years.
