Climate Science Weekly — 2026-09-03
A new United Nations report warns that the world is on track to miss its 1.5-degree Celsius climate target, identifying carbon removal combined with emissions reduction as the only remaining pathway to avert catastrophic warming. Meanwhile, new research indicates global warming has accelerated, with the planet warming at roughly 0.35°C per decade over the past ten years, compared to just under 0.2°C per decade from 1970 to 2015. Additionally, attribution analyses highlight how climate change boosted United States temperatures in August 2026.

Key Research & Findings
Acceleration of Global Warming Rates
- Published in: ScienceDaily (Reporting on peer-reviewed research)
- Key finding: After removing the effects of El Niño, volcanic eruptions, and solar cycles, researchers found that the planet has warmed at roughly 0.35°C per decade over the past ten years, compared with just under 0.2°C per decade from 1970 to 2015.
- Why it matters: This sharp acceleration suggests that feedback loops may be intensifying faster than previously modeled, requiring more aggressive near-term mitigation strategies.
August 2026 Temperature Attribution Analysis
- Published in: Europe Says (Aggregation of attribution studies)
- Key finding: An analysis of how climate change boosted United States temperatures in August 2026 was released, detailing the specific contribution of anthropogenic warming to recent heat anomalies.
- Why it matters: Rapid attribution studies provide immediate evidence linking extreme weather events to climate change, informing adaptation policy and public awareness.
CMIP7 Emissions Scenarios Explained
- Published in: Carbon Brief
- Key finding: A detailed explainer on the new CMIP7 emissions scenarios was published, unpacking how climate modelling groups designed these coordinated simulations to explore future climate change and how they differ from previous generations.
- Why it matters: These scenarios form the backbone of future IPCC reports and national climate strategies; understanding their design is critical for accurate risk assessment.
Climate Data & Observations
| Metric | Value | Source |
|---|---|---|
| Global Warming Rate (Past 10 Years) | ~0.35°C per decade | |
| Global Warming Rate (1970–2015) | Just under 0.2°C per decade | |
| US Temperature Anomaly Attribution | Boosted by climate change in Aug 2026 |
The data indicates a significant divergence in warming rates, with the current decade showing nearly double the rate of warming observed during the late 20th and early 21st centuries when natural variability factors are excluded. This acceleration underscores the urgency highlighted by recent UN warnings about overshooting temperature targets.
Policy & Action
- UN Report on 1.5-Degree Target: The United Nations released a report stating the world will miss its 1.5-degree climate target, warning that carbon removal combined with emissions reduction is the only remaining pathway to avert catastrophic levels of warming.
- Beef Industry Influence on Science: New investigative reporting highlights how the beef industry captures climate science by pairing scientists with industry mentors, potentially distorting research and foreclosing possibilities for limiting sector growth.
What to Watch Next
- CMIP7 Model Implementation: Researchers and policymakers will be closely monitoring how the newly explained CMIP7 emissions scenarios are integrated into national climate models and upcoming assessment reports.
- Ongoing Attribution Studies: Continued release of rapid attribution analyses for extreme weather events, such as those following the August 2026 heatwaves, will provide further evidence for climate liability and adaptation funding discussions.
- Carbon Removal Policy Development: Following the UN's warning, expect increased legislative and corporate focus on scaling carbon removal technologies as a critical component of remaining climate pathways.
