For the first time ever, scientists have observed in near real time a cloud of air pollution created as a SpaceX rocket burned up in Earth's atmosphere.

Scientists tracked lithium pollution from a SpaceX Falcon 9 reentry in real time, linking rocket debris to atmospheric changes using LIDAR measurements over Europe.

A new study published in the Journal of Climate reveals how surface warming in Antarctica, particularly over the Antarctic Peninsula, is significantly altering the stability of the lowest layers of ...

The Pacific Ocean is warming so quickly that scientists had to find a new method for detecting and predicting El Niño and La Niña events.

Researchers at the University of Tokyo used isotope-enabled ensemble modeling and 45 years of data to better trace ...

Scientists can now follow the path of a single drop of water across the globe. Water is made of hydrogen and oxygen, and some of these atoms naturally ...

A powerful shift is unfolding deep beneath the Pacific. After months of La Niña dominance, ocean heat is rising fast and trade winds are faltering.

Scientists have developed a powerful new way to trace the journey of water across the planet by reading tiny atomic clues hidden inside it. Slightly heavier versions of hydrogen and oxygen, called ...

Water is made of hydrogen and oxygen, and sometimes these atoms are slightly heavier than usual. These heavier forms are ...

Scientists have found a powerful new way to follow water as it moves around the planet—by tracking subtle “fingerprints” hidden inside its atoms.
