Los beneficios climáticos de los bosques van mucho más allá del secuestro de carbono

by Santiago Flórez 23 May 202227 March 2023

Los bosques son “esencialmente sistemas de aire acondicionado” gracias a procesos biofísicos como la evapotranspiración y la rugosidad del dosel forestal.

Open and Fair Data in Tropical Forests

Rishika Pardikar, Science Writer by Rishika Pardikar 6 May 202230 May 2024

People who gather ground data on tropical forests are highly disadvantaged compared to the users of such data. A new paper suggests long-term collaborations as a path forward.

Climate Benefits of Forests Go Far Beyond Carbon Sequestration

by Santiago Flórez 26 April 20221 June 2023

Forests are “essentially air-conditioning systems” thanks to biophysical processes like evapotranspiration and canopy roughness.

Extreme Lithium Isotope Fractionations During Intense Weathering

by Lixin Jin 18 April 202221 December 2022

Extreme lithium fractionation is observed when primary minerals in andesite are transformed to secondary clay minerals and then to oxides with intensive chemical weathering in a tropical climate.

Understanding Abrupt Climate Change in the Late Quaternary

by Raymond S. Bradley and Henry F. Diaz 18 November 20212 July 2024

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?

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.

Raising Central American Orography Improves Climate Simulation

by Sarah Kang 9 June 20218 March 2022

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

Convective Transport Explains “Missing” Ice near the Tropical Tropopause

by David Shultz 10 May 202129 March 2022

Spaceborne lidar shows that more ice than expected is leaving the tropical tropopause layer in the atmosphere.
