A Post-Impact Deep Freeze for Dinosaurs

by Aubrey Zerkle 2 September 202222 February 2023

New research supports the hypothesis that dinosaurs were done in by climate change after an asteroid impact kicked up a massive plume of sulfur gases that circled the globe for several decades.

How Did Diatoms Evolve to Swap Zinc for the Toxic Metal Cadmium?

Sarah Stanley, Science Writer by Sarah Stanley 17 March 20213 May 2022

New network analysis suggests that zinc and cadmium sulfides weathered simultaneously in geological history, making cadmium a suitable substitute in photosynthetic pathways when zinc was scarce.

Martian Dust Activities Induce Electrochemistry

by Mariek E. Schmidt 7 January 202115 March 2023

Amorphous materials generated from sulfur and chloride salts by electrostatic discharge in a Mars chamber suggest widespread electrical processes during dust activities.

The Overlooked Role of Sulfur Dioxide Emissions from Volcanoes

by Lynn Russell 10 March 202022 April 2022

Volcanoes can warm as much as they cool. Prior simulations have neglected the important warming effects of sulfur dioxide emissions, making some results colder than they should be.

Can Water Vapor Help Forecast When a Volcano Will Blow?

by E. Underwood 10 July 201715 November 2022

A widely used technique to monitor sulfur dioxide was tweaked to focus on water vapor at Peru’s Sabancaya Volcano. Results show that the volcano steamed up prior to its 2016 eruption.

Air Pollutant Plays Lesser Role in Climate Change Than Expected

Lucas Joel by L. Joel 26 October 20167 July 2022

Satellite data indicate that pollution control efforts that curbed levels of sulfur dioxide gas did not cause a major decrease in carbon dioxide absorption by plants.

Scientists use balloons to measure atmospheric ash and assess how volcanic eruption eruptions affect climate.

Evaluating the Impact of Maryland's Healthy Air Act

by Terri Cook 12 May 201627 February 2023

Reducing emissions of short-lived gaseous sulfur pollutants from power plants had an immediate, local benefit, but controlling longer-lasting harmful particulate matter will require regional action.
