Cyclone Nivar hits Puducherry, weakens after landfall

Cyclone Nivar made landfall near Puducherry late Wednesday night. The region, along with parts of neighbouring Tamil Nadu reported heavy rainfall. My Thursday morning, however, the cyclone had weakened significantly, and was downgraded to a ‘severe cyclonic storm’ by the India Meteorological Department (IMD) as it moved to north coastal Tamil Nadu. No loss of life has been reported so far.

2°C rise could lead to five-fold increase in global exposure to extreme events: Study 

A recent study revealed that global warming has more than doubled the land area and population that is annually exposed to six categories of extreme events – tropical cyclones, droughts, river floods, wildfires, droughts and heatwaves. And it will get worse as global warming increases. The study estimated that a temperature rise of 2°C above pre-industrial levels could lead to a five-fold increase in global exposure to such extreme weather events. Tropical and sub-tropical areas would face larger increases than areas in higher latitudes, according to the study. South Asia is likely to be the worst affected, the study predicted. 

Policy intervention, climate education key to encouraging low-carbon behaviour: Study

With nearly two-thirds of global greenhouse gases linked to daily human activities, a new study attempted to delve into changes in individual behaviour that could be key to mitigating climate change. The study, published in ScienceDirect, made four key recommendations that could trigger low-carbon behaviour – policy intervention such as carbon tax or energy tax, upgrading infrastructure geared towards low-carbon activities such as green transportation, improving climate education and implementing better incentive measures.
