On average, Americans spend about 90% of their time indoors, and the air we breathe at work, school or home affects our overall health and well-being.

A critical ocean layer for El Niño–Southern Oscillation (ENSO) dynamics.

Project CETI and Harvard have established a new reinforcement learning framework for rendezvous with whales using autonomous robots, combining sensing from diverse sensor streams.

Using data from an instrument designed by NASA’s Jet Propulsion Laboratory in Southern California, the nonprofit Carbon Mapper has released the first methane and carbon dioxide detections from the Tanager-1 satellite. The detections highlight methane plumes in Pakistan and Texas, as well as a carbon dioxide plume in South Africa.

The meteorological data recorded over the past two decades by sensors of the Roque de los Muchachos astronomical observatory facilities point to a rise of 1.1 ºC in the average temperature. 

A new study in Nature finds that up to 215 million hectares of land (an area larger than Mexico) in humid tropical regions around the world has the potential to naturally regrow. 

New scalable, robust surface prevents 100% of frost formation on flat areas for a week.

Trees and forests are often seen as symbolic of nature, and for good reason: They are vitally important to both the planet and to people.

A hole that opens annually in the ozone layer over Earth’s southern pole was relatively small in 2024 compared to other years.

In perhaps the first long-term study of CO2 fluxes in northern forests growing on permafrost, an Osaka Metropolitan University-led research team has found that climate change increased not only the sources of carbon, but also the CO2 sinks.
