Kelp’s Carbon Sink Potential Could Be Blocked by Coastal Darkening
Coastal darkening, an environmental threat researchers are only beginning to study, is found to dramatically reduce the productivity of kelp.
西伯利亚科雷马河的多年冻土碳元素含量极小
新的研究发现,北极河流目前运输的多年冻土来源的溶解有机碳有限,这对理解该地区变化的碳循环及其加速气候变化的潜力具有启示意义。
Famine Weed Becomes More Toxic, Invasive in Carbon-Rich Atmosphere
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.
Earthly Lava Tubes May Offer Insights into Extraterrestrial Life
New research finds that Actinobacteria in lava caves fix carbon and survive independent of surface inputs, offering a fresh perspective in the search for life beyond Earth.
A New Focus on the Neglected Carbonate Critical Zone
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
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.
Small Climate Changes Could Be Magnified by Natural Processes
A new study uses modeling techniques to uncover how small incidents of warming may be turned into hyperthermal events lasting thousands of years.
Forest Recovery in the Amazon Is a Slow Process
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?
Researchers uncover how black carbon evolves from hydrophobic particles to cloud nucleation sites, eventually removing the heat-absorbing particles from the sky.
