In this wide-ranging conversation with Arati Kumar Rao, Dr. Roxy Koll explains why climate change is no longer a distant, gradual phenomenon but an accelerating cascade of interconnected risks. They discuss El Niño and monsoon dynamics to extreme rainfall, Himalayan hazards, sea-level rise, urban heat, forest-driven rainfall recycling, climate-sensitive disease, agriculture, and the communication gap between science, policy, and the public.
