How to cover climate change, biodiversity, and environmental conventions for UPSC?

To cover these topics, adopt a thematic and institutional approach. For Climate Change, master the science (Greenhouse effect) and global responses like the UNFCCC and the Paris Agreement.
For Biodiversity, focus on the IUCN Red List, National Parks, and the Wildlife Protection Act.
For Conventions, create a table for major treaties—like CBD, CITES, and Ramsar—tracking their objectives, India's status, and recent COP (Conference of Parties) outcomes.
Use PMF IAS or Sleepy Classes to link these static conventions to current global climate debates and India's "Net Zero" targets.
