Aurorae such as the southern lights, seen here over Antarctica, show the geomagnetic field in action. Some areas of the field, which shields Earth’s surface from charged solar particles, are stronger ...

The ocean has helped mitigate global warming by absorbing around a quarter of anthropogenic carbon dioxide (CO 2) emissions, along with more than 90% of the excess heat those emissions generate. This ...

Lead is a neurotoxin that can damage multiple body systems and lead to learning and developmental problems. The element has been phased out of use in paint, gasoline, and other industrial applications ...

Coupling an AI-driven model of the atmosphere with a model of the ocean could help scientists create highly efficient emulations of the entire Earth system. Modelers have demonstrated that artificial ...

McDougall and Argall now report observations of a switchback-shaped structure in Earth’s magnetic field, suggesting that switchbacks can also form near planets. The researchers discovered the ...
