Exam-oriented handwritten-style notes — every page laid out like class notes, with highlighting, boxes and a mind map, built to be read the night before rather than skimmed.
Unit 6 of the CBSE Class 12 Political Science paper carries 6 marks out of 80, checked against CBSE’s own 2026-27 curriculum document. The trap in this unit is answering it as science. The paper is not asking what global warming is; it is asking who should pay to stop it, and why the answer is disputed.
What is inside

- Complete topic-by-topic notes, NCERT-aligned, in CBSE’s own topic order

- The North-South argument set out from both sides — the developed world’s case and the developing world’s case, each given fairly, because a question asking you to evaluate needs both

- A 31-term glossary of every definition the paper can ask for

Written for the 2026-27 syllabus
Nothing from CBSE’s list for this unit is left out — all seven sub-topics are covered. The Cold War Era and US Hegemony in World Politics were removed from the 2026-27 syllabus and appear nowhere in this set.
Figures that change year to year — current emission totals, or the present state of a particular negotiation — are deliberately kept out. The dates and proportions here are the ones NCERT itself uses and the ones the paper asks for, so the file does not go stale between the day you buy it and the day you sit the exam.
