Curated scientific intelligence

Discover

Developments across the published libraries, ranked by evidence, connection, and — if you follow topics — relevance to you. Each card is a movement in the literature: what changed, how the evidence is labeled, and why it matters.

Each development carries an evidence label. What the labels mean

Latest is ordered by when PaperFren added the explanation, not by the study's original publication date.

CMIP6 runs hotter — but its regional extremes scale like CMIP5's

Evidence: Strengthening

What changed

Regional scaling with warming level is robust across generations, and at +1.5 °C the regional term dominates the uncertainty. The CMIP6 archive was still incomplete when this ran, and the analysis does not explain the regional differences it finds.

Storm surge and heavy rain arrive together far more often than independence assumes

Evidence: Emerging

What changed

Their dependence is strong now and strengthens under warming across most of the global coastline. The analysis excludes large river catchments and mean sea-level rise, uses six CMIP5 models at roughly 100 km coastal spacing, and stops short of full inundation modelling.

Aerosols · Ozone

Published 2017 · Explained Sep 2026

The same aerosol feedback cuts winter ozone and raises it in summer

Evidence: Emerging

What changed

The feedback improves model skill in both seasons and produces opposite-signed ozone responses. Heterogeneous N₂O₅ chemistry is not quantified, two months of one year cannot represent all conditions, and urban monitors may not represent rural ozone.

Fine-particle pollution fell about 20% in the southeastern US — measured from orbit

Evidence: Strengthening

What changed

A 1 km surface resolves spatial structure across the region with good cross-validated skill. The maps are statistical predictions rather than speciated measurements, cloud-obscured retrievals leave gaps, and the study relates nothing to health outcomes.
