Continued growth in population will lead to further use of fossil fuels and a rapid increase in the atmospheric pollution. Notice a morning smog above Kohima, a relatively smaller town as compared to our megalopolises.
Abstract: There appears to be a consensus now among climate scientists that man has significantly altered his environment by indiscriminate burning of fossil fuels; and this anthropogenic effect on climate has exceeded solar heating of the earth in the past two decades. Advanced models of climate have clearly shown that the unprecedented high temperatures recorded in the late nineties could not be explained if man made changes in the atmospheric chemistry are not taken into account. Therefore, it is time that we think about possible ways of coping with a warmer world in the near future.

Heatwaves are no longer climate anomalies; they are the new normal. As India enters an era of prolonged, intense, and unpredictable thermal extremes, its rural backbone is showing signs of distress. I...
India, a nation perched precariously on one of the most active seismic belts in the world, faces a curious paradox: despite mounting geological evidence and rising urban vulnerability, public understa...
Heatwaves have become one of the most lethal and least acknowledged consequences of climate change in India. What was once an occasional extreme is now a defining feature of India’s seasonal climate,...
India’s coastal regions, stretching thousands of kilometers, are on the frontlines of a creeping environmental crisis—saltwater intrusion. Unlike cyclones or tsunamis, this is a disaster that doesn’t...
