2015, the year gone by has set its own record as the third hottest year in India since 1901, especially the last quarter sweeping the country with warmest temperatures ever recorded, said Indian Meteorological department (IMO) and at global level the year 2015 remains the hottest year, according to the World Meteorological Organization (WMO).
India’s annual mean temperature remained at 0.67 degree celsius more than the 1961-1990 average, while the 12 of the country’s 15 warmest years were witnessed since 2001 and the past decade was the warmest on record, showcasing the exponential growth of pollution and green house effect on Mother Nature.
Despite refusal by the Climate Change minister, the country had seen many natural calamities including extreme heavy rainfall, heat and cold waves, snow fall, thunderstorm, dust storm, lightening and massive floods in the last 15 years.
Severe hailstorm over northwest, central and adjoining peninsular India in March 2015 to severe heat waves in May in the South to lightning in Odisha, Maharashtra and Telangana to heavy rains in Madhya Pradesh, Gujarat, Rajasthan during southwest monsoon, besides unprecedented rainfall in Tamil Nadu and Andhra Pradesh during northeast monsoon are some of the highlights listed by the IMD in its report.
However, at the global level 2015 remains the hottest ever year with 1 degree celsius above the average since the pre-industrial era, said WMO. “An exceptionally strong El Nino and global warming caused by greenhouse gases joined forces with dramatic effect on the climate system in 2015,” said WMO Secretary General Petteri Taalas.
“The power of El Nino will fade in the coming months but the impacts of human-induced climate change will be with us for many decades,” Taalas cautioned.
Echoing similar view, D.S. Pai of IMD said, “There is an increasing trend in temperatures in the last 100 years in line with global warming. Important observation is that the last four months were the warmest on record.”
Howevver, 2015 also remains a hallmark for climate change talks with the Paris Summit of several country heads including India vowing to push solar energy and reduce green house effects considerably on voluntarily declared targets. Otherwise, the global weather will see a drastic change by 2050, warn environmentalists.
Global annual average temperatures anomalies (relative to 1961-1990) based on an average of three global temperature data sets (HadCRUT.184.108.40.206, GISTEMP and NOAAGlobalTemp) from 1950 to 2015. Bars are coloured according to whether the year was classified as an El Niño year (red), a La Niña year (blue) or an ENSO-neutral year (grey). Note uncertainty ranges are not shown, but are around 0.1°C.
