Attribution constraints reveal stronger future intensification of the upper‑level Hadley circulation
Attribution constraints reveal stronger future intensification of the upper‑level Hadley circulation Gaby Clark Scientific Editor Robert Egan Associate Editor The Hadley circulation, a key atmospheric conveyor belt transporting heat and moisture from the tropics to the subtropics, directly influences subtropical aridity, the positions of tropical rainfall belts, and extreme weather risks. However, climate models have long shown inconsistencies in simulating its upper-level intensity...
The sliding door moment for 'awestruck' Diamonds bolter
analysis Super Netball Round-Up: 'Awestruck' Grenvold bolts into the Diamonds squad Mon 1 Jun 2026 at 6:51pm With two rounds left of the regular season, there are still eight teams in the running for the Super Netball premiership. Even if the chances for two of them are quite slim.
The American Missile Crisis
Recent global conflicts, from Russia and Ukraine to Iran and Israel, have seen a resurgent awareness of the frailty of US munitions stock, which has been drawn down by both direct and indirect involvement in these events. While exact stockpile volumes are not disclosed, it is estimated that supplies of US warheads and the missiles that carry them have declined by nearly an order of magnitude since their peak during the Cuban Missile Crisis. Analysts have estimated that in the event of a...
Record wildfire losses rocked 2025 even as global burned area neared all-time lows
Record wildfire losses rocked 2025 even as global burned area neared all-time lows Sadie Harley Scientific Editor Robert Egan Associate Editor A new analysis of global wildfire activity in 2025 reveals the world experienced some of the most destructive and deadly fire events in recent history, despite the second lowest area burned since 2002. It highlights a continued trend toward fires becoming increasingly extreme, costly, and disastrous—both economically and in lives lost. Led by the...
Atmospheric Predictability Beyond 30 Days with Machine Learning
arXiv:2504.20238v2 Announce Type: replace Abstract: Atmospheric predictability research has long held that rapid error growth at small spatial scales imposes an intrinsic limit of roughly two weeks on deterministic weather forecast skill. We challenge this limit using GraphCast, a machine-learning weather model, by optimizing initial conditions for twice-daily forecasts spanning 2020. This approach yields an average error reduction of 86% at ten days relative to control forecasts from...
The looming El Niño could be bad – but much worse is to come
A “Godzilla El Niño” is coming, according to some newspaper headlines. The actual story is that there is an 80 per cent chance of an El Niño developing by September. Most models forecast a moderate event – but some suggest it could be very strong, perhaps even a so-called super El Niño.
