Context
-
- The UNEP’s Emissions Gap Report: Limiting Overshoot warns that the world is likely to breach the 1.5°C warming threshold, making adaptation increasingly important.
- If countries fully implement their current climate pledges, warming could reach around 1.8°C, while current policies point towards 2.6°C.
- The report accepts the reality of an “overshoot” scenario but argues that crossing 1.5°C does not mean climate action is futile.
- India must therefore balance its legitimate concerns about historical responsibility and climate justice with greater emphasis on adaptation and mitigation.
The “Overshoot, Peak and Decline” Pathway
-
- Global temperatures may temporarily rise above 1.5°C, followed by:
Overshoot → Peak warming → Decline - Keeping the peak as low and short as possible can reduce irreversible climate damages.
- Preventing even a 0.1°C increase is easier than removing that warming later.
- Global temperatures may temporarily rise above 1.5°C, followed by:
Key Insight: Every fraction of a degree matters.
Methane: A Near-Term Opportunity
-
- The report gives greater importance to greenhouse gases beyond CO₂, particularly methane.
- Methane reduction can provide significant near-term climate benefits because of its strong warming effect.
- More than 155 countries, including India, have joined the Global Methane Pledge, committing to reduce anthropogenic methane emissions by at least 30% below 2020 levels by 2030.
India’s Climate Dilemma
India as a Victim
-
- India has below-global-average per-capita emissions.
- It remains vulnerable to climate-induced:
- Floods
- Extreme weather
- Heat
- Himalayan disasters
- India therefore seeks finance and affordable technology from historically high-emitting developed countries.
But India is Also a Major Emitter
-
- India’s large overall emissions mean it cannot completely distance itself from global mitigation responsibilities.
- The article argues that India should recognise this reality while continuing to demand equity and climate justice.
Way Forward
-
- Combine mitigation with adaptation rather than treating them as alternatives.
- Accelerate methane reduction and clean-energy transition.
- Strengthen climate-resilient infrastructure.
- Demand greater climate finance and technology transfer from developed countries.
- Calibrate India’s diplomatic messaging around both historical responsibility and present-day climate action.
- Prepare for an inevitable degree of climate overshoot through robust adaptation.
Conclusion
The 1.5°C threshold should not become an excuse for climate inaction. For India, the appropriate strategy is “climate justice + climate responsibility + climate resilience.” India must continue highlighting historical emissions while simultaneously preparing for a warmer world.
