- Climate
How to make recyclable plastics out of CO2 to slow climate change
Companies are turning atmospheric CO2 from smokestacks and landfills into plastics to shrink their carbon footprint.
- Climate
A carbon footprint life cycle assessment can cut down on greenwashing
As companies try to reduce their carbon footprint, many are doing life cycle assessments to quantify the full carbon cost of their products.
- Climate
A coral pollution study unexpectedly helped explain Hurricane Maria’s fury
Tracking coral reef pollution in Puerto Rico, conservation researchers discovered by chance how the coastal ocean fueled Hurricane Maria.
- Earth
In 2021, a deadly volcano erupted with no warning. Here’s why
Before the Nyiragongo eruption, underground magma was already close to the surface and so didn’t trigger instruments that look for lava movement.
