UNEP pathway for global warming limit breach

UNEP has introduced an 'overshoot, peak, and decline' pathway to manage global warming beyond the 1.5 degrees Celsius limit set by the 2015 Paris Agreement.
The 1.5 degrees Celsius limit is now projected to be breached in the next few years.
Current global policies suggest a warming trajectory of 2.6 degrees Celsius by 2100; even full implementation of national climate plans leads to a 1.8 degrees Celsius peak.
The 'Global Mutirão' (collective effort) consensus from COP30 (2025) officially acknowledged the likelihood of a temporary overshoot.
Consequences of exceeding 1.5 degrees Celsius include faster sea-level rise, coral reef collapse, glacier loss (over 25% by 2100), and a potential 14% decline in global food production by 2050.
Irreversible tipping points include the collapse of West Antarctic and Greenland ice sheets, the Atlantic Meridional Overturning Circulation, and the Amazon rainforest.
Mitigation strategies include deep, rapid emission cuts and large-scale nature-based removals like reforestation.
The United States has formally exited the Paris Agreement and withdrawn from the UNFCCC, IPCC, and the Green Climate Fund.

UNEP report 'Limiting Overshoot' highlights that breaching 1.5°C global warming causes irreversible losses.
Current climate pledges put the world on track for 1.8°C warming; current policies suggest 2.6°C.
The 1.5°C limit has already been breached; strong El Niño events (e.g., 2027) threaten further spikes.
The 'overshoot, peak and decline' pathway involves exceeding 1.5°C temporarily before returning below it by century-end.
Neutralising heating is significantly more difficult than preventing it.
Methane is responsible for 0.5°C of current warming; reducing it is a key near-term mitigation strategy.
Global Methane Pledge aims for 30% reduction in anthropogenic methane by 2030 from 2020 levels; over 155 countries have joined, excluding India.
Developing economies emphasize historical carbon responsibility, the need for climate finance, and technology transfer.
India faces a complex position: it is a victim of climate change with low per capita emissions, yet is increasingly viewed as a major emitter by smaller, vulnerable nations.
