The years 2015 and 2016 saw record levels of excess carbon dioxide in the atmosphere, even though human carbon emissions have stabilized in recent years. Now, scientists think they know why.

Scientists, Students in Prescott, Arizona, Help LIGO Detect Gravitational Waves

This year’s Nobel Prize in Physics was awarded to three men, but the detection of gravitational waves was the work of a thousand scientists and students — 10 of them from Embry-Riddle Aeronautical University in Prescott.

Worth Doing Right: How Climate Change Could Throw a Wrench Into Road repairs

Repairing with the wrong materials for shifting climates could be a road to nowhere, like this spot in the Suffolk village of Covehithe. Picture by Timothyansell123.

The American Society of Civil Engineers has given America’s roads a D rating. But a recent study shows that trying to raise that grade without accounting for climate change could put the country’s roadways at risk.

The pipeline leak that spilled sewage into Arizona’s Santa Cruz River is sealed, but another pollution problem persists — one many other American waterways share.

Contaminants of emerging concern, or CECs, are chemicals from drugs and personal care products that most wastewater treatment plants don’t filter out. Some, including estrogenic compounds from products like synthetic birth control, disrupt the hormones of aquatic wildlife, harming reproduction.
