Committed warming delays stabilization
Key Questions
What does the Earth Energy Imbalance study imply for warming timelines?
Observed EEI data suggests heating reversal is unlikely before the early 2040s even under low emissions, more than 10 years later than many current models project.
How do UN and Met Office forecasts affect Paris Agreement goals?
Global temperatures are expected to stay near record levels for the next five years, with a high likelihood of temporarily exceeding 1.5°C and closing the window for Paris targets.
What is the WMO's latest probability for a new record year?
The WMO now assigns an 86% chance of a new global temperature record by 2030, with 2027 identified as the likely next peak due to El Niño.
How is regional warming in Korea compared to the global average?
Korea is warming at twice the global average rate, increasing risks of both extreme heat and potential winter cold snaps.
What are the implications for carbon budgets and adaptation?
The delayed stabilization timeline reinforces urgency for faster mitigation and more robust adaptation planning worldwide.
WMO forecasts 91% chance of temporarily exceeding 1.5°C in next 5 years, 86% chance of new record year by 2030, with 2027 likely next record (El Niño-driven). Arctic warming at 2.8°C above baseline. New study using observed Earth Energy Imbalance (EEI) constrains climate projections, finding that heating reversal is unlikely before early 2040s even under low emissions—more than 10 years later than current models suggest. This directly challenges optimistic timelines and has major implications for carbon budgets and adaptation planning, reinforcing urgency for both mitigation and adaptation. Korea warming twice global average adds regional specificity.
