Considering the past observed data, "consecutive droughts together with heat wave conditions could be ringing the bell of climate change for this otherwise heavenly state," the report by M G Manoj, research scientist, Advanced Centre for Atmospheric Radar Research, CUSAT, said.
"The projections of climate change for Kerala reveals an increase in temperature by 2-3 degrees Celsius by the end of this century," the report appeared in 'Kerala Climate', a publication of Institute of Climate Change Studies, said.
Intense lightning and thunder, gusty winds and rainfall, heat waves, droughts, polluted environment, pattern shifts in crops, reduced plant and animal productivity etc would be some of the consequences of the rising temperature, it said.
Frequency and duration of weak rainfall periods and drought condition is gradually increasing in Kerala, it said.
"Kerala, the most abundant rainfall-receiving state of the country, witnessed the most deficient rain this year," it said.
"The large-scale dynamics driven by warming in the Indian Ocean and changes in rainfall pattern has resulted in a deficient monsoon for Kerala this year," the report, titled 'Concerns on Changing Patterns of Climate over Kerala', said.
Due to increase in anthropogenic activities and emissions, global temperatures have shown a warming trend of 0.85 degree Celsius over the period 1880-2012, it said.
"This is a permanent factor in increasing the surface temperatures, even at our state too," it said, adding that "during the recent years, minimum temperatures (night-time) have increased more than daytime temperatures, suggesting the possible role of moisture and the greenhouse gases.
