Precise proposition checked
Cleaner air, not CO₂, is driving Europe's heat, and net-zero policy is making temperatures rise.
Full post context: Net Stupid Zero is contributing to rising temperatures not helping… Cleaner air = higher temps, not CO2.
Scope of this check: This verdict separates the supported aerosol-cooling effect from the unsupported claims that it replaces greenhouse-gas forcing or ties recent heat to net-zero policy.
What the evidence shows
Reducing sulfate pollution removes some regional cooling and can add to European summer warming. The cited research does not show that CO₂ stopped driving warming or that net-zero policy caused the heat.
- Roldán-Gómez and colleagues associate sulfate-aerosol reductions since about 1980 with circulation changes and additional European summer warming; the paper does not identify net-zero policy as the cause of recent heat.
- IPCC Working Group I assesses anthropogenic aerosols as a net cooling influence that has offset part of the warming caused by greenhouse gases.
- The IPCC identifies greenhouse-gas forcing as the dominant driver of observed increases in hot extremes, with aerosol forcing providing a partial offset rather than an alternative explanation.

What is true
Sulfate aerosols reflect sunlight and affect clouds, producing a net cooling influence. Cleaning up air pollution can therefore reveal some warming that aerosols had masked and can change regional circulation. That effect can operate alongside greenhouse-gas warming and does not make pollution a safe climate strategy.
Where the claim fails
The post turns a real secondary climate effect into a replacement for the primary driver. The cited study examines how declining sulfate aerosols can alter regional circulation and add European summer warming; it does not attribute recent heatwaves to net-zero policy, nor does it overturn the measured warming effect of accumulated greenhouse gases.
Limits and uncertainty
This legacy case predates ACC's separate limitations field. Its original verdict, scope, sources, and revision record are preserved without adding a retroactive certainty estimate.
Assessment after the evidence
Reducing sulfate pollution removes some regional cooling and can add to European summer warming. The cited research does not show that CO₂ stopped driving warming or that net-zero policy caused the heat.
How the framing works
How scientists know
Scientists compare observed temperature and circulation patterns with climate-model experiments that vary individual forcings such as greenhouse gases and aerosols. Multiple lines of evidence, including radiative physics, atmospheric composition measurements, detection-and-attribution studies, and assessed model ensembles, separate each contribution and its uncertainty.
Editorial boundaries
ACC evaluates the claim. It does not infer intent, coordination, funding, or representativeness without direct evidence specific to that attribution.
