Briefings

A COP31 report concludes that the Paris Agreement's 1.5°C warming limit has been exceeded, shifting focus to minimizing the duration and magnitude of this breach. This finding, released before the COP31 summit, marks a critical turning point in global climate policy, signaling that the window for effective mitigation has closed. The report emphasizes that the primary challenge is now reducing the speed and extent of the temperature rise rather than merely avoiding the threshold.

Key points

• The Paris Agreement's 1.5°C warming limit has been exceeded, as confirmed by the PNUMA annual report.
• The report prioritizes minimizing the duration and magnitude of the temperature breach rather than just avoiding the limit.

Context

This finding is significant as it marks a definitive end to the Paris Agreement's primary mitigation window, requiring immediate and drastic action to prevent irreversible climate damage.

Limitations

The evidence is limited to a single report from the PNUMA, released prior to COP31. The report does not provide specific data on the exact temperature breach magnitude or duration, nor does it offer a forecast for future climate scenarios beyond the immediate context of the report's release.
