Weather and Climate — Policy Changes

IPCC Assessment Reports (e.g., AR6)	Ongoing (AR6 in 2021-2023)	The Intergovernmental Panel on Climate Change (IPCC) periodically releases comprehensive assessment reports that synthesize the latest scientific understanding of climate change, its impacts, and future risks. These reports are not 'amendments' in a legal sense but represent significant updates and refinements to the global scientific consensus on climate science.	These reports fundamentally update our understanding of climate change, influencing international climate policy, national climate action plans (like India's NAPCC), and scientific research priorities. They provide the authoritative scientific basis for global climate negotiations and policy decisions, effectively 'amending' or evolving our collective knowledge and approach to climate challenges.
National Monsoon Mission (NMM)	2012 (launched)	While not a constitutional amendment, the National Monsoon Mission (NMM) represents a significant policy 'amendment' or enhancement in India's approach to monsoon forecasting. It was launched by the Ministry of Earth Sciences to improve monsoon prediction capabilities through advanced modeling and observational systems.	The NMM has led to substantial improvements in short-to-medium range and extended-range monsoon forecasts, providing crucial information for agricultural planning, water resource management, and disaster preparedness. It signifies a policy shift towards leveraging cutting-edge science for more accurate and actionable weather and climate information, directly impacting India's economic and social resilience.
