Deadly heat + humidity by century end, but Met may fail to predict it

IMD does not take humidity into account though heat-wave deaths have risen three-fold in 23 years

High humidity levels coinciding with high temperatures are likely to create lethal weather conditions and imperil the lives of millions across large parts of India, Pakistan and Bangladesh by the end of the century, according to new research published in the scientific journal Science Advances. Climate change will make such conditions more frequent as the 21st century comes to a close, the study said.

Yet, the Indian Meteorological Department (IMD) does not take humidity into account in characterising heat waves, even though temperatures that fall below IMD’s definition of a heat wave, when combined with a
