In the aftermath of historically severe wildfires in 2020, a study of Cascade Range watersheds found that stream vertebrates are doing surprising well, highlighted by flourishing fish populations.

A new study co-led by the University of Oxford has found that global aviation emissions could be reduced by 50-75% through combining three strategies to boost efficiency: flying only the most fuel-efficient aircraft, switching to all-economy layouts, and increasing passenger loads. Crucially, the study shows that around a 11% reduction in global aviation emissions is achievable immediately, by using the most efficient aircraft that airlines already have more strategically on routes they already fly.

Industrial waste, dyes and chemicals all potentially pollute our waters.

Evaporative cooling is far from new – it has been used to cool living spaces and drinking water for centuries – but the Matter of Tech Lab at Cornell Tech has come up with a new way to deploy an old idea.

Artificial intelligence is getting more powerful – but it’s also racking up a massive energy bill.

From land–borne pathogens to high–speed vessel strikes, Pacific whales and dolphins are caught in a “perfect storm” where human-caused trauma and infectious diseases were found in more than 65% of investigated strandings.

Engineers at the University of California San Diego have developed a spray-on polymer coating that could help plants resist harmful bacterial infections and survive drought.

Carbon removal projects could prove vital in offsetting methane emissions – the second largest contributor to global warming.

The Glacier Mass Balance Intercomparison Exercise, or GlaMBIE—a European Space Agency project launched in 2022—aims to strengthen global glacier monitoring by combining field observations with satellite-based data from remote sensing technologies.

Since New York City introduced congestion pricing in January 2025, the state has heralded significant reductions in traffic and rush hour delays, fewer crashes and noise complaints, and toll revenue projected to hit $500 million by the end of the year.
