Tamil Nadu – Very High Heat Risk
▪ According to a recent study by the Council on Energy, Environment and Water (CEEW), Tamil Nadu ranks fifth among States with high to very high heat risk.
▪ In fact, none of Tamil Nadu’s districts falls under the very low or low heat risk categories.
▪ About 11% of the districts face moderate heat risk, while 43% are classified as high risk, and 46% fall under the very high heat risk category, indicating that much of the State is confronting severe and widespread heat vulnerability
▪ According to the CEEW study, national data from 1981 to 2022 shows that the frequency of very
warm nights is increasing faster than very hot days, particularly in the last decade.
▪ This trend is influenced by natural climate cycles such as El Niño and La Niña.
▪ In Tamil Nadu, vulnerability to heat is exacerbated by the high prevalence of non-communicable diseases such as hypertension and diabetes.
Neolithic age grooves discovered near Boothapandi in Kanniyakumari district
▪ The Archaeological Survey of India recently discovered one of first rock grooves in Kanniyakumari district which were created during the neolithic age, where people used to sharpen their weapons.
▪ During the study, several grooves made by the neolithic age which were around 4,000 years old, were discovered.
▪ These grooves were created by neolithic people to sharpen their tools which were used for multiple purposes such as hunting, ploughing and digging.
▪ Similar grooves were found in other parts of Tamil Nadu such as Krishnagiri, Tiruvannamalai and Villupuram.
▪ The Neolithic Period, also called the New Stone Age, is the final stage of cultural evolution or
technological development among prehistoric humans.
