New research could improve the efficiency of electrochemical carbon-dioxide capture and release by six times and cut costs by at least 20 percent. MIT researchers added nanoscale filtering membranes to a carbon-capture system, separating the ions that carry out the capture and release steps, and enabling both steps to proceed more efficiently.

The Arctic is one of the coldest places on Earth, but in recent decades, the region has been rapidly warming, at a rate three to four times faster than the global average. However, current climate models have been unable to account for this increased pace. Now, researchers at Kyushu University have reported in a study, published April 29 in Ocean-Land-Atmosphere Research, that clouds may be to blame.

A novel analysis suggests more than 3,500 animal species are threatened by climate change and also sheds light on huge gaps in fully understanding the risk to the animal kingdom.

Corals are the architects of reefs throughout tropical seas, providing protection and sustenance for the species that depend on them. Coral reefs protect coastlines from storm surge, put tourist dollars in coffers, and provide cultural richness in the way of food and fishing practices.

The loss of coral ecosystems is a critical problem that has propelled coral scientists into action to save species that may not survive the rapid pace of climate change and environmental degradation.

Just one hundred corporations are behind a fifth of the documented extractive conflicts worldwide, exposing how companies from the Global North seize resources and profits, while social and ecological harms are imposed on the Global South, according to a recent study by Institute of Environmental Science and Technology at the Universitat Autònoma de Barcelona (ICTA-UAB).
