Why in news: World Weather Attribution (WWA) reported that human-caused global heating increased the intensity of heavy rain in the Cyclone Senyar-affected region by 28-160%.
The WWA study found that heavy rain periods in Sri Lanka are now 9% to 50% more intense due to climate change. These extreme weather events, including Cyclone Ditwah and Cyclone Senyar, resulted in over 1,750 deaths.

EnvironmentWestern tragopan: A rare pheasant species found in the Himalayan region.
FactIUCN estimate: 3,000-9,500 western tragopans remain in the wild.
BodyIUCN: International Union for the Conservation of Nature, provides population estimates for the species.
Mains angle
Q. Examine the role of captive breeding and community-based tourism in the conservation of endangered Himalayan species like the western tragopan.
Ecological bottleneck: Stalled reintroduction due to lack of established protocols and research
Economic incentive: Community-based tourism as a tool to reduce habitat disturbance
Fiscal constraint: Budgetary limitations hindering the transition from captive breeding to wild reintroduction
Why in news: The Commission for Air Quality Management (CAQM) informed the Supreme Court that a lack of enforcement and specific court orders have allowed over 63 lakh over-aged vehicles to continue operating in Delhi
The CAQM reported that over 63 lakh vehicles exceeding their designated BS standards are currently on the road. The Commission proposed phasing out diesel auto-rickshaws in the National Capital Region (NCR) by 2026.
