Explainer: What is decarbonization?
Lowering carbon levels in our atmosphere to stabilize the climate may start with switching from fossil fuels to greener energy sources.

Explainer: All about carbon dioxide
Animals and other life on Earth exhale carbon dioxide, which plants use for photosynthesis. But too much of this gas can perturb Earth’s climate.

Microplastic pollution aids viruses and prolongs their infectivity
The tiny plastic bits give these germs safe havens. That protection seems to increase as the plastic ages and breaks into ever smaller pieces.

Greenland’s inland ice is melting far faster than anyone thought
Inland melting of the Northeast Greenland Ice Stream is accelerating — and may contribute far more to sea level rise than earlier estimates suggested.
