The US puts none. https://news.luyml.com/red-40-safe-label-cumulative-exposure https://news.luyml.com/red-40-safe-label-cumulative-exposure The EU requires foods with Red 40 and five other synthetic dyes to warn that they may affect children's activity and attention. The American limit is set one additive at a time — 7 mg per kilo of body weight a day — while a child eats several of them at once.

The trial called that 0.5-point gap statistically significant; the threshold at which a patient notices any change at all is 2.0.

The International Seabed Authority already lists 32 exploration contracts, 17 of them inside that zone. The licensing has run ahead of the naming.

Pteropods — the free-swimming snails at the base of many marine food webs — build their shells out of exactly that carbonate.

The federal record says it has fallen by two thirds. https://news.luyml.com/invisible-yield-soil-degradation https://news.luyml.com/invisible-yield-soil-degradation In June we reported that soil loss on the world’s cropland is accelerating, and gave no source for the figure. The USDA has measured American cropland since the 1930s: 14.9 tons an acre in 1930, 7.8 in 1982, 6.3 in 1992, 4.63 in 2017. Here is what we got wrong, and the harder question underneath it.

In the California Current the horizon rose over 100 metres between the 1994 survey and the repeat, where circulation does much of the work.

Remove every one of those animals and stored carbon falls 2.4 to 3.0 percent — because other, lighter trees grow into the space. The canopy does not fall. It is replaced.

The finding underneath it: as particulate fell, ozone was the pollutant still driving the damage. Sacramento has an ozone problem.

Here is how the AQI in your phone is actually calculated. https://news.luyml.com/variance-protocol-aqi https://news.luyml.com/variance-protocol-aqi In June we described a 'Variance Protocol' that buries hazardous hours inside a 24-hour average. No such protocol exists — we made the term up — and the EPA's real method does close to the opposite: when air quality turns variable, the window shortens toward three hours.

In June 2021 that mechanism produced a 500 hPa height with no precedent since 1948 — an event attribution work puts at 1-in-1000 years now and at least 150 times rarer without human warming.

Those services never had a market price, so they never entered the cost-benefit analysis that approved the build.
