The UNEP 'Limiting Overshoot' report warns that global warming will exceed 1.5°C, projecting 1.8°C under current pledges and 2.6°C under active policies. Highlighting methane reduction as a critical near-term climate lever, the report sets a high-stakes agenda for COP31, intensifying global debates over climate justice, adaptation finance, and India's position on international environmental pacts.
The release of the United Nations Environment Programme’s (UNEP) 'Limiting Overshoot' report underscores a stark climate reality: the 1.5°C global warming limit has effectively been breached under current trajectories, with the planet on course to warm to 1.8°C by 2100 under optimal pledges and 2.6°C under existing policies. Rather than abandoning climate targets, the report outlines an 'overshoot, peak and decline' pathway. Crucially, it identifies rapid reduction of methane emissions—which contribute roughly 0.5°C to current warming—as the most potent near-term mitigation lever. While over 155 countries have signed the Global Methane Pledge to cut emissions by 30% by 2030, India remains a notable non-signatory, prioritizing food security and smallholder farmer livelihoods. Developing economies continue to emphasize the principle of Common But Differentiated Responsibilities and Respective Capabilities (CBDR-RC), highlighting historic emissions of developed nations and demanding robust climate finance and technology transfer. The upcoming COP31 negotiations face intense pressure to bridge mitigation and adaptation finance gaps, especially in light of escalating climate-induced disasters like the Bhotekoshi flash-flood in Nepal. For UPSC aspirants, this issue sits at the heart of global environmental governance, climate diplomacy, and India's delicate balancing act between rapid economic development and net-zero commitments.
