Atmospheric Carbon Crosses 428 ppm Threshold
Mauna Loa observatory reports a sustained reading above 428 parts per million for the first time in recorded instrumental history. The measurement, corroborated by three independent stations across the Pacific basin, arrived at the beginning of the northern spring drawdown — a period in which values ordinarily decline.
A team at the Institute for Carbon Studies, working with twisted bilayer graphene under ambient pressure, has produced the first peer-reviewed evidence of resistance-free electron transport above 290 K. The finding, if independently replicated, reframes carbon as the substrate of the next computational epoch.

Deep-Ocean Sediment Cores Rewrite the Permian Carbon Record
Drill cores recovered from the Mariana Trough preserve an unbroken isotopic record across the Permian–Triassic boundary, revealing a carbon excursion more abrupt and more asymmetric than the prevailing models had predicted. The archive extends the resolution of deep-time carbon by an order of magnitude.

Direct Air Capture Reaches Cost Parity in Pilot Facility
A twelve-month pilot in the Atacama reports a levelised cost of $89 per tonne CO₂ — the first field deployment to cross the threshold long considered the minimum for credible large-scale carbon withdrawal. Auditors note that the figure excludes permanent geological storage.

A Synthetic Forest: Biochar as Literary Archive
A collaboration between soil scientists and archivists has encoded digital text into the molecular structure of engineered biochar, producing a medium that sequesters carbon while preserving literature across geological timescales. The first inscription: a complete edition of Lucretius.

A City of Carbon
Each structure below is a research programme. Scroll, and the campus grows — a procedural archive of carbon knowledge, one discovery per silhouette.
The grid is ten by ten. Seventy per cent of cells carry a structure. Heights are drawn from a seeded pseudo-random distribution; the city is therefore identical on every reload, a stable archive rather than a shifting skyline.

Editorial Note
tanso.news is composed in Spectral, a serif designed for screen reading, with data and citations set in Inconsolata. The single-typeface discipline reflects a belief that journalism, like scholarship, is strengthened by constraint. No tracking, no advertising, no sidebar — only the narrow column and the record it carries.
Our method: every claim is traced to an observation, every observation to an instrument, every instrument to the carbon it measures. The city you have just scrolled through is not decoration. It is a map of the knowledge on which each dispatch stands.
