Can We Observe How Cloud Clustering Affects the Radiation Budget?

by Sarah Kang 20 August 20208 March 2022

Satellite observational analysis confirms that lower-atmospheric stability and cloud clustering are major factors modulating the tropical radiation budget that had been suggested by modeling studies.

Soil Carbon May Not Remain Bogged Down in a Warmer World

by Eric Davidson 27 July 20201 April 2022

Carbon was lost from an experimentally warmed boreal peatland much faster than it took to accumulate. Elevated CO₂ had little effect on stored carbon, requiring re-evaluation of model assumptions.

Effects of Particles on Climate Remain Unsettled

by D. Wuebbles 27 July 202023 July 2020

Major advances have been made in the understanding of the physics and chemistry of particles, but major uncertainties remain in determining their radiative forcing effects on climate.

The Perils of Computing Too Much and Thinking Too Little

by B. Stevens 25 June 202021 September 2022

Big steps forward are synonymous with new ideas – a thought that merits mindfulness if we aspire to train students to do more than merely train machines.

Eruption and Emissions Take Credit for Ocean Carbon Sink Changes

by Eileen Hofmann 3 June 202028 February 2023

A new model explains why the ocean’s capacity to take up carbon was reduced on a decadal scale, by accounting for reduced pCO₂ emissions and ocean state changes due to the eruption of Mt. Pinatubo.

Using Saturn’s Rings as a Seismometer

by F. Nimmo 12 May 202024 May 2023

The Cassini spacecraft observed spiral density waves in the rings of Saturn which can be used to probe its interior structure and rotation.

Explaining Cold and Fresh Southern Polar Ocean Surface Waters

by P. Rizzoli 6 May 202017 August 2022

Global climate models do not reproduce observed trends of the Southern polar ocean surface, but an increase in wind-transported sea ice that melts and inhibits mixing may account for the disparity.

Health Concerns from Combined Heat and Pollution in South Asia

by D. Wuebbles 24 April 202014 April 2023

Little research has studied the impacts of combined climate conditions. Together, heat events and poor air quality in South Asia amplify the imminent health challenge.
