A new study highlights a critical misunderstanding in how biochar is used to fight climate change and improve soils, warning that oversimplified claims could undermine both scientific progress and carbon markets.

Coastal wetlands are among the planet’s most effective natural carbon sinks, but their ability to store carbon is increasingly threatened by climate change and human activity. Now, a new field study suggests that adding biochar to these ecosystems could significantly boost their carbon storage capacity, with tidal forces playing a surprisingly beneficial role.

Researchers at the University of Massachusetts Amherst recently unveiled a tool to combat climate change, fossil-fuel dependency, skyrocketing home-heating bills and gentrification all at once—a simple fabric treated with a special photothermal dye that, when placed on outside walls, can help keep a home 8.64ºF warmer over the course of a day.

There is a closing 20-year window in which decisions on climate and land use will determine the fate of dozens of native birds, butterflies and plants across Great Britain, which is already one of the most nature-depleted countries globally.

That is the warning in a new study led by the UK Centre for Ecology & Hydrology (UKCEH), which, for the first time, predicts how different combined environmental changes would affect the survival of species within 1km square areas across the country.

For decades, biodiversity has been known to peak near the equator. But a new study reveals a striking exception: certain trematode parasites are more common in cooler, temperate waters. By tracking infections across snails, crabs and fish, researchers found that host movement, local conditions and temperature shape where parasites thrive. In warmer regions, infections are more lethal; in cooler waters, hosts survive longer, allowing parasites to persist – offering new insight into how ecosystems function and how disease may shift with climate change.

A new study shows that systems designed to capture methane from cow manure, called dairy digesters, are highly effective. But on the rare occasions they fail, the leaks are large enough to offset their climate benefits.

Led by scholars from The Hong Kong University of Science and Technology (HKUST), a research team has discovered that, since the early 2000s, both sea surface temperature changes near the equator and the associated atmospheric adjustments over the Pacific have accelerated markedly—becoming a key driver of the increasingly rapid loss of Arctic sea ice during autumn. The findings highlight that, under ongoing global warming, climate linkages between distant regions are far more dynamic and complex than previously understood.
