Article 1: Warning on warming
Why in news: UNEP’s Limiting Overshoot report warns that 1.5°C warming is being breached, UNEP’s Limiting Overshoot report warns that 1.5°C warming is being breached, urging rapid methane cuts and an “overshoot, peak and decline” pathway, while highlighting India’s climate-finance dilemma. Cuts and an “overshoot, peak and decline” pathway, while highlighting India’s climate-finance dilemma.
Key Details
- 1.5°C breach: Global warming is already exceeding the 1.5°C threshold, making irreversible climate impacts increasingly likely.
- Overshoot pathway: UNEP proposes limiting temperature rise, reaching a peak, and bringing warming below 1.5°C by century-end.
- Methane action: Cutting methane offers one of the fastest ways to slow near-term warming; 155+ countries have joined the Global Methane Pledge.
- India’s dilemma: India has low per-capita emissions but faces pressure as a major developing emitter and climate-vulnerable country.
- Climate finance: India demands greater adaptation finance and affordable technology from developed countries, raising tensions ahead of COP31 in Türkiye.
UNEP Report and the 1.5°C Threshold
- UNEP’s “Limiting Overshoot” report warns that crossing 1.5°C of warming can cause irreversible climate losses.
- Even if all countries fulfil their existing climate pledges, warming could reach around 1.8°C.
- Under current policies, global temperatures could rise to approximately 2.6°C.
- The world has already experienced periods above the 1.5°C threshold, making climate overshoot an immediate concern.
- The report argues that exceeding 1.5°C does not mean climate action has become irrelevant.
Overshoot, Peak and Decline Pathway
- The report proposes an “overshoot, peak and decline” approach to address unavoidable temperature increases.
- Under this pathway, global temperatures temporarily rise above 1.5°C before reaching a peak.
- Countries should collectively ensure that the peak warming is as low as possible.
- Global temperatures should then gradually decline and return below 1.5°C by the end of the century.
- Preventing additional warming is easier than trying to reverse its impacts later, making immediate mitigation essential.
Methane: Key to Near-Term Warming Reduction
- The report places greater emphasis on greenhouse gases other than carbon dioxide, particularly methane.
- Methane contributes significantly to current warming, accounting for roughly 0.5°C of present warming.
- Reducing methane emissions can produce faster short-term climate benefits than relying only on long-term CO₂ reductions.
- More than 155 countries have joined the Global Methane Pledge, committing to cut anthropogenic methane emissions by at least 30% from 2020 levels by 2030.
- India has not joined the Global Methane Pledge, reflecting its concerns about development priorities and mitigation responsibilities.
India’s Development and Climate-Finance Concerns
- India argues that developing countries have contributed relatively less to historical emissions while remaining highly vulnerable to climate impacts.
- India stresses the need for greater climate finance and affordable clean technologies from developed countries.
- Its position reflects the principle of common but differentiated responsibilities and respective capabilities (CBDR-RC).
- The report gives relatively limited attention to adaptation finance, despite developing countries facing increasing climate-related losses.
- India therefore faces the challenge of balancing development needs, mitigation commitments, adaptation and climate justice.
India’s Changing Climate-Diplomacy Challenge
- Ahead of COP31 in Türkiye, disagreements between developed and developing countries over mitigation, finance and responsibility are likely to continue.
- The Bhote Koshi disaster in Nepal has added urgency to concerns about the vulnerability of smaller Himalayan countries.
- Nepal has urged major emitters, including China, the U.S. and India, to recognise the consequences of rising temperatures for vulnerable countries.
- Although India has below-global-average per-capita emissions, some countries increasingly view it as part of the climate problem because of its large aggregate emissions.
- India should therefore acknowledge the reality of a 1.5°C world, strengthen climate action while protecting development interests, and adapt its international messaging accordingly.
Conclusion
A 1.5°C world demands neither climate fatalism nor unrealistic expectations, but faster, equitable action. India must strengthen mitigation, particularly methane reduction, while firmly advocating adaptation finance and technology transfer. Its climate diplomacy should recognise that its developmental needs coexist with growing global expectations. COP31 offers an opportunity to reconcile climate justice with collective responsibility through differentiated, credible and ambitious action.
