Climate Science Weekly — 2026-11-06
As the world braces for COP31 in Turkey, a new study reveals that global warming has accelerated to nearly double the historical average pace since 2015, while Carbon Brief analysis indicates 2026 is on track to tie with 2024 as the warmest year on record. Simultaneously, research into ice-age climate shifts challenges previous assumptions about the speed of ocean circulation recovery, offering new perspectives on future Atlantic circulation stability.

Key Research & Findings
Acceleration of Global Warming Rates
- Published in: ScienceDaily (via Potsdam Institute for Climate Impact Research)
- Key finding: Scientists have detected a major acceleration in global temperatures since around 2015. The warming rate has surged to approximately 0.35°C per decade, which is nearly double the average pace observed from 1970 to 2015 (which was just under 0.2°C per decade).
- Why it matters: This sharp acceleration, confirmed after removing the effects of El Niño, volcanic eruptions, and solar cycles, suggests the planet is entering a faster warming phase than previously modeled, raising urgent concerns for climate mitigation timelines.
Reassessment of Ice-Age Abrupt Climate Shifts
- Published in: Phys.org (via high-resolution speleothem records from China and India)
- Key finding: New high-resolution speleothem records and isotope-enabled climate models indicate that abrupt glacial ocean circulation recoveries took centuries, not decades.
- Why it matters: This finding fundamentally alters how scientists assess the potential speed of future Atlantic Meridional Overturning Circulation (AMOC) changes, suggesting that while abrupt shifts are possible, their recovery mechanisms operate on much longer timescales than previously thought.
2026 Temperature Record Projections
- Published in: Carbon Brief
- Key finding: Analysis across six global temperature datasets gives 2026 a 67% chance of surpassing 2024 as the warmest year on record.
- Why it matters: If confirmed, this would mark another extreme outlier in global temperature records, reinforcing the trend of accelerating heat accumulation in the Earth system.
Climate Data & Observations
| Metric | Value | Source |
|---|---|---|
| Current Global Warming Rate | ~0.35°C per decade | |
| Historical Warming Rate (1970–2015) | Just under 0.2°C per decade | |
| Probability 2026 is Warmest Year | 67% |
The data indicates a stark divergence between historical warming trends and current observations, with the recent decade showing a near-doubling of warming velocity compared to the 1970–2015 baseline. This acceleration is occurring despite the natural variability factors like El Niño being accounted for, pointing to underlying systemic drivers.
Policy & Action
- COP31 Focus on Electrification: Organizers of the UN climate summit (COP31), taking place in Antalya, Türkiye from November 9–20, 2026, are aiming for an agreement on electrification to bring down global emissions. The head of negotiations states that a commitment to significantly boost the electrification of economies would define the summit's success.
- Paris Agreement Ten-Year Review: As COP31 convenes, analysts are reviewing the ten-year legacy of the Paris Agreement. Nearly 200 countries pledged to limit warming to 1.5°C, but assessments show mixed results on delivery versus pledges, with many falling short.
- COP31 Agenda and Carbon Markets: The summit will address Article 6 talks and climate finance. There is significant pressure to translate diplomatic pledges into tangible action, particularly as projections indicate the world is on track to overshoot the 1.5°C threshold.
What to Watch Next
- COP31 Negotiation Texts: Countries in Antalya are currently negotiating the wording of legal agreements. Tracking these texts is crucial as they determine the operational rules for carbon markets and finance mechanisms.
- Article 6 Implementation: The progress of Article 6 talks at COP31 will be a key indicator of whether international carbon markets can function effectively without double-counting emissions.
- Verification of 2026 Temperature Records: As the year concludes, final data from NASA, NOAA, and Copernicus will confirm whether 2026 indeed surpasses 2024, which would have significant implications for climate model calibration and policy targets.
