El Niño-Southern Oscillation and Radiation Two-Way Coupling

by Suzana Camargo 9 February 20221 August 2022

Changes in sea surface temperature during ENSO events and radiation are related, suggesting a two-way coupling between sea surface temperature and radiation in coupled climate variability.

Tropical Climate Change Is a Puzzle—Could Aerosols Be a Piece?

by Andrew Chapman 9 September 202114 April 2022

The eastern tropical Pacific Ocean hasn’t warmed as much as climate change models projected. A new study shows that aerosols in the atmosphere could be responsible.

Corals Make Reliable Recorders of El Niño Fluctuations

by Terri Cook 24 July 202029 September 2021

A new tool that reconciles modeling and paleoclimate data builds confidence that tropical Pacific corals reliably archive natural variability in the El Niño–Southern Oscillation climate pattern.
