Famine Weed Becomes More Toxic, Invasive in Carbon-Rich Atmosphere

by Fionna M. D. Samuels 22 September 202129 March 2023

A noxious weed’s success in Australia could indicate that some plants are benefitting from our carbon-rich atmosphere, becoming more invasive, competitive, and toxic.

A New Focus on the Neglected Carbonate Critical Zone

by J. B. Martin, P. C. De Grammont, M. D. Covington and L. Toran 20 September 202128 January 2022

Studies of Earth’s critical zone have largely focused on areas underlain by silicate bedrock, leaving gaps in our understanding of widespread and vital carbonate-dominated landscapes.

Minimal Evidence of Permafrost Carbon in Siberia’s Kolyma River

by Terri Cook 20 September 202120 September 2023

New research finds that Arctic rivers currently transport limited permafrost-derived dissolved organic carbon, which has implications for understanding the region’s changing carbon cycle—and its potential to accelerate climate change.

Forest Recovery in the Amazon Is a Slow Process

by Meghie Rodrigues 14 September 202129 April 2022

For the first time, a study analyzes Amazon forest loss and recovery at national and subnational levels. One finding shows that new plantings offset less than 10% of emissions associated with deforestation.

How Long Do Black Carbon Particles Linger in the Atmosphere?

Sarah Derouin, Science Writer by Sarah Derouin 10 September 20218 March 2022

Researchers uncover how black carbon evolves from hydrophobic particles to cloud nucleation sites, eventually removing the heat-absorbing particles from the sky.
