Absorbing Aerosols Mediate High Temperature Extremes in India

Greenhouse gas-induced global warming is primarily believed to accentuate high temperature extremes, while anthropogenic aerosols, largely radiation-scattering sulphate, are believed to cause an overall cooling in most world regions. However, the Indian region is marked by an abundance of absorbing aerosols, such as black carbon and dust. Using analyses based on GCM simulations from 1981-2010, as well as, satellite and ground-based observational data from 1979-2013, there is emerging evidence that absorbing aerosols play a role in mediating pre-monsoon hot extremes in north-central India.
