Countries around the world pledged in the Paris Agreement to limit warming to 1.5 degrees Celsius, or, at most, 2 degrees Celsius. 

North Carolina State University researchers found they could filter carbon dioxide from air and gas mixtures at promising rates using a proposed new textile-based filter that combines cotton fabric and an enzyme called carbonic anhydrase – one of nature’s tools for speeding chemical reactions.

Eastern monarch butterflies covered 35 percent more ground in the mountain forests of central Mexico this past winter than they did the year before, according to a survey from the World Wildlife Fund.

A total knee replacement can greatly improve a patient’s quality of life, but first the procedure itself will create nearly 30 pounds of waste, about half of which presents a biohazard and requires energy-intensive treatment for safe disposal.

A new study by a team of scientists and policy analysts from across the nation suggests that there are multiple pathways to achieve this goal – but big commitments will need to be made, immediately.

New research, recently published in the Proceedings of the National Academy of Sciences and led by the University of Massachusetts Amherst, finds that the ecological effect of invasive species alone is comparable to the combined effects of invasives plus warming temperatures, drought or nitrogen deposition. 

Sparse data often make it difficult to track how climate change is affecting populations of insect species. 

Personal exposure to heat is an environmental hazard that might not make the same headlines as hurricanes or wildfires. But its effects are devastating. 

Scientists have come up with a new classification scheme for mountain belts that uses just a single number to describe whether the elevation of the mountain belt is controlled mainly by weathering and erosion or by properties of the Earth’s crust, i.e., the lithospheric strength: the “Beaumont number” (Bm). 

Giant kelp forests around the world have struggled to stay healthy in recent decades, with some vanishing altogether.
