Q. 2016 was the warmest year: Comment on increasing global temperature in a last three years.
Jan 21, 2017 Related to : GS Paper-3

Ans :


Recently USA’s two leading science agencies jointly declared that, 2016 was the hottest year on record, surpassing the previous record set just last year, which itself had topped a record set in 2014. 2016 was the warmest year on the instrumental record since the late 19th century, and the hottest of three record-breaking years in a row.


  • The rise in temperature as being largely driven by increased carbon dioxide and other human-made emissions into the atmosphere. The growing temperature was aggravated by the El Nino phenomenon of 2015-16.
  • The global warming pattern must be seen in the context of declining sea ice cover in the Arctic, compounding the loss of ice sheets in Greenland and the Antarctic. 
  • In the Arctic, which is witnessing a decline in the extent of sea ice cover in the lowest month at the rate of about 13% every decade, melting creates a vicious circle of more exposure of dark areas to sunlight, higher melting and more dark surface absorbing heat. 
  • Such phenomena accelerate the rate of global warming, with consequences through climate change for coastal areas, access to water, farming and human health.
  • A global warming with climate change in the form of altered rainfall, drought, floods, lost biodiversity and reduced crop yields would affect millions across the globe.
  • Hence increasing trend of warming is a warning to all countries that they cannot afford to rely on carbon-intensive growth any longer. All countries across the globe must strengthen with clear and unambiguous actions against global warming, which should lead to a scaling up of renewable energy and measurable decline in use of fossil fuels.


The increasing global temperature is cause of concerns for all stakeholders across the globe. Last three years in a row have witnessed record highest temperatures since industrial times. Hence all countries across globe must effectively implement their commitments to reduce carbon emissions and should promote renewable energies effectively.
