Understanding Abrupt Climate Change in the Late Quaternary
During the late Quaternary period, a series of abrupt climate changes in the tropics and sub-tropics driven by changes in ocean circulation were both dramatic and disruptive.

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

Raising Central American Orography Improves Climate Simulation
Elevation of Central American orography significantly reduces the pervasive tropical rainfall bias by blocking the easterlies and consequently warming the northeastern tropical Pacific.
