- What is the news?
The Centre for Science and Environment (CSE) and the magazine Down To Earth released the State of India’s Environment (SoE) 2026 report at the Anil Agarwal Dialogue 2026.Â
- Two big warnings: 7 of the 9 planetary boundaries have been crossed, and India saw extreme weather on 99% of the days in 2025.
- What are ‘planetary boundaries’? Think of them as nine safety limits for the Earth. Staying inside them keeps the planet safe for human life.
-     Crossed (7): climate change, biosphere integrity (loss of living variety), land-use change, freshwater use, biogeochemical flows (too much nitrogen & phosphorus), novel entities (plastics, chemicals), and the newest — ocean acidification.
- Â Â Â Â Still safe (2): the ozone layer and air-borne aerosols.
Fig: Seven of the nine planetary boundaries are now crossed (bar lengths are only indicative).
- Other key findings:
-     The sea is now 30-40% more acidic than before industries began — this harms corals and shellfish.
-     India’s land is about 0.9°C warmer (2015-24) than in the early 1900s.
- Â Â Â Â Only about 15% of Indians live where air quality is continuously monitored.
-     The world is close to crossing the 1.5°C warming line set by the Paris Agreement.
UPSC Value Box
| Term | Meaning |
| Planetary Boundaries | A 2009 idea (Stockholm Resilience Centre) of 9 Earth limits we should stay within to stay safe. |
| Ocean acidification | The sea turns more acidic as it absorbs COâ‚‚; this harms shell- and coral-forming life. |
| Biosphere integrity | The health and variety of living things; losing it makes nature unstable. |
| 1.5°C threshold | The Paris Agreement’s safer limit for global warming above pre-industrial levels. |
 Prelims Practice Question
- With reference to the “planetary boundaries” framework, consider the following statements:
- It was developed by the Stockholm Resilience Centre.
- Ocean acidification is the most recent boundary judged to have been crossed.
- The framework lists twelve planetary boundaries.
(a) 1 and 2 only
(b) 2 and 3 only
(c) 1 and 3 only
(d) 1, 2 and 3
Answer: (a) 1 and 2 only
Why: Statement 1 is right — it was developed by a team led by Johan Rockström at the Stockholm Resilience Centre (2009). Statement 2 is right — SoE 2026 says ocean acidification is the seventh and latest boundary crossed. Statement 3 is wrong — there are nine boundaries, not twelve.
