Decadal Forecasts with a SMYLE

by Kristopher B. Karnauskas 13 August 202511 August 2025

Scientists use a large suite of simulations with an established climate model to predict the Pacific Decadal Oscillation up to one year in advance, but El Niño can still get in the way.

Iron Emissions Are Shifting a North Pacific Plankton Bloom

by Mark DeGraff 6 August 20256 August 2025

Some of the iron emitted by industrial activity in East Asia is carried by winds into the North Pacific, where it nourishes iron-hungry phytoplankton.

Magnitude-8.8 Earthquake Strikes Western Pacific

by Jennifer Schmidt 30 July 202530 July 2025

One of the strongest earthquakes ever recorded struck off the eastern coast of Russia’s Kamchatka Peninsula Wednesday morning local time. Initially pegged at a magnitude-8.0, the quake was eventually upgraded to a magnitude-8.8. Adjusted magnitude estimates are not unusual for large earthquakes as more data become available.

Characterizing the Space Between Clouds and Clear Sky

by Susan Trumbore 7 February 20257 February 2025

The area near clouds is often classified as ‘clear sky’, but a new study demonstrates the potential biases of misclassifying these transition zones and their significance for Earth’s energy budget.
