Flathead catfish are rapidly reshaping the Susquehanna River’s ecosystem. Once introduced, these voracious predators climbed to the top of the food chain, forcing native fish like channel catfish and bass to shift diets and habitats. Using stable isotope analysis, researchers uncovered how the invaders disrupt food webs, broaden dietary overlaps, and destabilize energy flow across the river system. The findings show how a single invasive species can spark cascading ecological consequences.

Tiny ocean microbes called Prochlorococcus, once thought to be climate survivors, may struggle as seas warm. These cyanobacteria drive 5% of Earth’s photosynthesis and underpin much of the marine food web. A decade of research shows they thrive only within a narrow temperature range, and warming oceans could slash their populations by up to 50% in tropical waters.

Labor’s grassroots environmental action network wants the Albanese government to adopt a 2035 emissions reduction target of at least 70% as a show of global climate action leadership, countering warnings from big business about the cost of such a goal.
In her first interview as the new co-convener of Labor Environment Action Network (Lean), Louise Crawford also said she had faith the government would finally deliver long-awaited reforms to the Environment Protection and Biodiversity Conservation (EPBC) Act after plans collapsed in the previous term.

Figure calculated by Oil Change International has more than doubled since 2017 but is likely a vast understatement
The US currently subsidizes the fossil-fuel industry to the tune of nearly $31bn per year, according to a new analysis.
That figure, calculated by the environmental campaign group Oil Change International, has more than doubled since 2017. And it is likely a vast understatement, due to the difficulty of quantifying the financial gains from some government supports, and to a lack of transparency and reliable data from government sources, the group says.

World Cup may be forced into winter in future
Reports also looks at risks for 2030 and 2034 editions
The 2026 World Cup could be North America’s last without urgent climate adaptation, according to a new study highlighting extreme weather threats.
The Pitches in Peril report, published by Football for Future and Common Goal, found that 10 of the 16 venues are at very high risk of experiencing extreme heat stress conditions. By 2050, nearly 90% of North America’s host stadiums will require adaptation to extreme heat while one third will face water demand equalling or exceeding supply.

New rules come into force from 30 September in order to restore habitats and reduce flooding
Burning on England’s deep peat will be banned in order to restore habitats for rare wildlife and reduce air pollution and flooding, the government has said.
England’s peatlands are in poor shape due to having been burned, intensively drained and used as grouse moors. They naturally act like a sponge, with layers of moss and other vegetation, and store vast amounts of carbon: an estimated 3.2bn tonnes in the UK alone.
