August becomes the hottest month ever recorded globally, with Copernicus finding record-high average temperatures across both land and ocean. The data add to a year of exceptional heat and underscore how marine temperatures as well as surface conditions are helping drive the global climate system into unprecedented territory.

The August heat also pushes global temperatures beyond a key benchmark, with scientists attributing the record to long-term human-driven warming amplified by a strong El Niño. The extreme warmth is visible not only worldwide but across the Northern Hemisphere, showing how broadly the heat is now distributed.

Separate analyses put August as tied for the hottest month on record, with global temperatures nearing 1.65°C above pre-industrial levels. Even with slight differences in datasets, the overall picture is the same: the planet remains in an extended spell of unusual heat that began earlier in the year.

Anthropic says it blocks several uses of its Claude model linked to biological research that could aid bioweapons development. The company says it intervenes when requests appear dangerous, while acknowledging that some of the same methods can also serve legitimate medical or vaccine research, making intent hard to judge.

Authorities in South Australia test a juvenile whale carcass for H5 bird flu after it washes ashore near Victor Harbor. Officials cordon off the beach while they examine whether the animal is connected to the wider avian influenza threat that has raised concern about transmission into marine wildlife.

NATO allies say they thwart a Russian operation aimed at undersea data cables in the Arctic after detecting and intercepting naval activity. The incident highlights the scientific and strategic importance of seabed infrastructure in polar regions, where communications links are increasingly exposed to geopolitical tension.

Gateway Mining identifies a new 3-kilometre gold target at its Yandal project ahead of drilling. The company says the undrilled zone resembles its earlier Cowza discovery, setting up the next exploration phase as it tests whether the target can add a significant new mineralized trend to the project.
