Research shows CO2 radiative forcing causes summer cooling in India due to unique topography.
Himalayas and Hindu Kush Mountains increase cloud cover, reducing solar radiation and cooling India.
CMIP6 simulations confirm a cooling pattern south of the Himalayas during boreal summer.
CO2 radiative forcing induces summer cooling over India
Recent research published in *Nature* reveals that CO2 radiative forcing induces summer cooling over India, a phenomenon not observed in East Asia. India's unique topography, particularly the Himalayas and Hindu Kush Mountains, plays a crucial role. These mountains promote moisture convergence and ascent, leading to increased cloud cover that reduces incoming solar radiation. This cooling effect is most pronounced during the boreal summer months (June-August).
