Towards a Global, Integrated View of Carbon Stocks Across Land, Ocean, and Atmosphere
Why an Integrated Carbon Perspective Matters As climate change continues to reshape carbon dynamics, understanding how carbon stocks are distributed and transferred among the land, ocean, and atmosphere becomes crucial. Recent Editors’ Highlights from AGU Advances emphasize that managing carbon stocks effectively requires a globally integrated view of carbon cycle processes that span local to…

Integrated Carbon Cycle: Managing Stocks Across Lands, Oceans, and Atmosphere
Understanding a Global Challenge As climate change accelerates, the world’s carbon stocks are shifting in complex ways across land, oceans, and the atmosphere. The challenge for policy makers, scientists, and land managers is to adopt an integrated view of the carbon cycle—one that connects carbon sources, sinks, and storage over different timescales and spatial scales.…

Integrated Carbon Stocks: A Global View of the Carbon Cycle
Overview Managing carbon stocks effectively requires more than isolated actions in one domain. Recent editors’ highlights from AGU Advances emphasize a globally integrated view of the carbon cycle—spanning land, ocean, and atmosphere—to understand how carbon moves, where it is stored, and how it can be manipulated or preserved in a warming world. This perspective helps…

Anatomy of a Phytoplankton Bloom North of Hawai’i
Introduction: A recurring ocean spectacle Every summer, satellite sensors reveal a vast, swirling bloom of microscopic life north of the Hawaiian Islands. These phytoplankton blooms, though invisible to the naked eye, color the surface of the Pacific and play a pivotal role in marine food webs and the global carbon cycle. Recent research from scientists…

Chemistry in Pictures: Tiny Ocean Engineers
Introduction: The Micro Architects of the Sea From the shimmering surface to the dark depths, the ocean hosts countless tiny builders whose work quietly sustains the global climate. Coccolithophores are among the most remarkable of these microscopic engineers. These single-celled marine algae construct intricate calcium carbonate shells—the unmistakable plates, spines, and lattice-like coverings that give…

Chemistry in Pictures: Tiny Ocean Engineers and the Carbon Sequestration Plankton
Introduction: The quiet architects of the carbon cycle In the vast and dynamic marine realm, microscopic algae perform outsized roles. Among them, coccolithophores—tiny, single-celled plankton with plated, spiky exteriors—stand out for their chemistry-rich contributions to Earth’s climate system. These “tiny ocean engineers” pull carbon dioxide from seawater and convert it into calcium carbonate shells, constructing…

After 40,000 Years, Microbes Are Awakening From Thawing Permafrost
Waking the Long-Frozen Microbes: A Window into the Arctic’s Hidden Life In a discovery that blends microbiology with climate science, researchers report that microbes buried in Alaskan permafrost for tens of thousands of years are reawakening as the freezer-like ground thaws. Some of these organisms have been trapped for as long as 40,000 years, yet…

Permafrost Microbes Awake After 40,000 Years
Ancient life in thawing ground raises climate questions In a striking reminder that the Arctic is not just cold but also a living archive, researchers report that microbes trapped in Alaskan permafrost for up to 40,000 years have reawakened. The discovery comes from samples taken from a deep, dark corridor known as the Permafrost Tunnel…

Permafrost Awakening: Microbes Reignite Arctic Emissions
Ancient Life Comes Back to Life in a Modern Climate Experiment In a startling glimpse of how the Arctic may respond to a warming world, researchers have revived microbes trapped in permafrost for up to 40,000 years. The study, conducted with samples from a deep underground Permafrost Tunnel Research Facility near Alaska, shows that frozen…

Hidden Climate Thermostats Could Accelerate or Alter the Timing of the Next Ice Age
Overview: A Two-Thermostat View of Earth’s Climate Scientists have long explored how Earth naturally regulates its climate on geological timescales. The classic model centers on the silicate weathering feedback: when the planet warms and rain increases, CO2 is drawn down through chemical reactions with silicate rocks, ultimately storing carbon in oceans and sediments. This slow…
