Many Pacific Island nations will lose 50 to 80 percent of marine species in their waters by the end of the 21st century if climate change continues unchecked, finds a new Nippon Foundation-Nereus Program study published in Marine Policy. This area of the ocean is projected to be the most severely impacted by aspects of climate change.

Deforested areas of the Amazon Basin have a limited ability to recover because of recent changes in climate, a study shows.

Traditional toxicity testing underestimates the risk that pharmaceutical and personal care product pollution poses to freshwater ecosystems. Criteria that account for ecological disruption – not just organism death – are needed to protect surface waters, which are under pressure from a growing population and escalating synthetic chemical use. So reports a new study published this week in Elementa.

The presence of artificial sweeteners in rural groundwater shows evidence for contamination by local septic system wastewater, researchers from the University of Waterloo have found.

Pesticides significantly reduce the number of pollen grains a bumblebee is able to collect, a new University of Stirling study has found.

Fossil leaves from Africa have resolved a prehistoric climate puzzle — and also confirm the link between carbon dioxide in the atmosphere and global warming.

We need to pay more attention to the health of the planet to save lives, and improve global health, now and in the future, Dr Samuel Myers said at The 2017 Academy of Medical Sciences & The Lancet International Health Lecture

We’re all familiar with tipping points, when crossing what might seem a minor threshold can lead to drastically different outcomes—the Super Bowl favorite that falls to last place with injury to a single lineman, a tomato seedling that surges skyward the moment it tops the shadowy confines of its clay pot.
