Looking for Climate Clues in China’s Great Wall
Looking for Climate Clues in China’s Great Wall
In northwestern China, desert conditions have preserved the farthest reaches of the Great Wall. Scientists are now exploring 2,000-year-old building materials for signs of the region’s past climate.
Microplastics Are the Not-So-Secret Ingredient in Marine Snow
Particles of tiny, degraded plastics coated with biofilms sink to the seafloor, carrying carbon with them.
Ecosystem Observations from Every Angle
Proximal remote sensing provides a bridge between ecosystem flux data at Earth’s surface and optical data from satellite sensors, improving our grasp of feedbacks between terrestrial ecosystems and climate.
A Transformative Carbon Sink in the Ocean?
Water-rock reactions in some hydrothermal systems produce both hydrogen, which could be tapped for clean energy, and alkaline solutions that could help draw down atmospheric carbon dioxide.
Measuring Carbon’s Flow from Land to Sea
A new study catalogs how dissolved inorganic carbon moves through southeast Alaska’s waterways.
Gently Down the Stream: Carbon’s Journey from Land to Sea and Beyond
Movement of carbon from land to ocean and atmosphere plays an important, but understudied, role in the global carbon cycle.
New Aerosol Model Better Represents Black Carbon Properties
An improved representation for black carbon microphysical and optical properties alleviates overestimations of aerosol absorption efficiency in global climate models.
How You Make Money Matters When It Comes to Carbon Emissions
Investment income is associated with more carbon emissions in the United States.
Our Evolving Understanding of Biological Carbon Export
The array of processes and organisms that make up the biological carbon pump has immense influence on Earth’s carbon cycle and climate. But there’s still much to learn about how the pump works.
