The atmospheric level of carbon dioxide — a gas that is great at trapping heat, contributing to climate change — is almost double what it was prior to the Industrial Revolution, yet it only constitutes 0.0415% of the air we breathe.

A study of adolescents aged 11-16 in London has found long-term exposure to PM2.5 is associated with higher blood pressure, with stronger associations seen in girls.

In two studies, researchers at the University of Turku have found that carbon sequestration and plant resilience as well as forage pasture yield can be increased through key adjustments in agricultural management.

Small isolated wetlands that are full for only part of the year are often the first to be removed for development or agriculture, but a new study shows that they can be twice as effective in protecting downstream lake or river ecosystems than if they were connected to them. 

As plastic pollution continues to mount, with growing risks to ecosystems and wildlife, manufacturers are beginning to make ambitious commitments to keep new plastics out of the environment.

Volcanoes draw plenty of attention when they erupt.

While microplastics have received significant attention in recent years for their negative environmental impacts, a new study from Oregon State University scientists found microfibers from synthetic materials as well as cotton impacted the behavior and growth of water organisms.

Electric vehicles are widely hailed as a key way to mitigate climate change through reduced emissions, but research on the dual benefits of reduced air pollution and improved health has been largely hypothetical.

In the study of human impact on the environment, there are few negative or stabilising feedbacks on climate change.  

Withstanding high temperatures and the light of 160 suns, a new catalyst is 10 times more efficient than previous sun-powered water-splitting devices of its kind.
