Human activity is contributing to pollution that is affecting our health.

Engineers at the University of British Columbia have developed a new water treatment that removes “forever chemicals” from drinking water safely, efficiently – and for good.

The 51-square kilometer (20-square-mile) pileup is an important yet poorly quantified part of the carbon cycle, scientists say.

Algae grown in transparent tanks or tubes supplied with carbon dioxide can convert the greenhouse gas into other compounds, such as food supplements or fuels. But the process leads to a buildup of algae on the surfaces that clouds them and reduces efficiency, requiring laborious cleanout procedures every couple of weeks.

On the slender wings of the tiny Pipistrel Velis Electro ride some of the greatest the hopes of the aviation industry — and the Waterloo Institute for Sustainable Aeronautics (WISA). 

Levels of carbon dioxide (CO2), methane and nitrous oxide, the three greenhouse gases emitted by human activity that are the most significant contributors to climate change, continued their historically high rates of growth in the atmosphere during 2022, according to NOAA scientists.

Reducing global carbon dioxide emissions is critical to avoiding a climate disaster, but current carbon removal methods are proving to be inadequate and costly.

Human activities emit many kinds of pollutants into the air, and without a molecule called hydroxide (OH), many of these pollutants would keep aggregating in the atmosphere.

As automobile electrification speeds up, the world faces an overwhelming need for critical metals and minerals to make atmosphere-saving electric vehicles possible.

Nearly 20 percent of today’s electricity in the United States comes from nuclear power.
