Rusting Fool’s Gold in Glaciers a Sign of Increased Carbon

According to a new study published by USC scientists in the Proceedings of the National Academy of Science, rock and soil breakdown in glaciers generates more acidity and releases more carbon than other forms of natural weathering. Perhaps most interestingly, it is the elevated oxidation of pyrite, popularly known as “fool’s gold,” in the glacial

Peat Bogs: From Fire Break to Fire Hazard

The peat bogs of the world, once waterlogged repositories of dead moss, are being converted into fuel-packed fire hazards that can burn for months and generate deadly smoke, warns a McMaster researcher.

Carbon Dioxide Biggest Player in Thawing Permafrost

Carbon dioxide emissions from dry and oxygen-rich environments will likely strengthen the climate forcing impact of thawing permafrost on top of methane release from oxygen-poor wetlands in the Arctic, according to a study in Nature Climate Change led by Northern Arizona University assistant research professor Christina Schädel. Schädel’s meta-analysis of 25 Arctic soil incubation studies

USGS Assesses Carbon Potential of Alaska Lands

In comparison to the lower 48 states, Alaskan forests, wetlands and permafrost contain larger stores of carbon, according to the first-of-its-kind assessment recently completed by the U.S. Geological Survey, the U.S. Forest Service and the University of Alaska at Fairbanks. “This benchmark assessment establishes significant baseline information to better understand carbon dynamics in Alaskan ecosystems,”

Clear-Cutting Destabilizes Carbon in Forest Soils, Dartmouth Study Finds

Clear-cutting loosens up carbon stored in forest soils, increasing the chances it will return to the atmosphere as carbon dioxide and contribute to climate change, a Dartmouth College study shows.

Fire and Ice: Gaging the Effects of Wildfire on Alaskan Permafrost

USGS scientists, in collaboration with researchers at the University of Minnesota and University of Alaska Fairbanks, have mapped belowground permafrost in areas of Alaska that have been affected by wildfire, years-to-decades after the fires occurred. “There has been global concern for many years about the effects of the warming climate on high-latitude permafrost and its

Warmer Pacific Ocean Could Release Millions of Tons of Seafloor Methane

Off the West Coast of the United States, methane gas is trapped in frozen layers below the seafloor. New research from the University of Washington shows that water at intermediate depths is warming enough to cause these carbon deposits to melt, releasing methane into the sediments and surrounding water.

New Evidence Highlights the Carbon-regulating Capacity of the Ocean

Gland, Switzerland, Dec. 9, 2014 – Protecting key carbon-absorbing areas of the ocean and conserving fish and krill stocks are critical for tackling climate change. This is one of the findings of a report released today by the International Union for Conservation of Nature (IUCN) in which top marine scientists describe how atmospheric carbon is captured, stored and

NASA and ESA Team to Test Greenhouse Gas Measurement Techniques

Scientists met in California this summer to test new methods for measuring greenhouse gases. This joint effort helps to show how ESA’s CarbonSat candidate satellite mission could identify sources of carbon dioxide and methane and how they disperse in the atmosphere. CarbonSat is a candidate for ESA’s eighth Earth Explorer mission.

Perú’s Carbon Quantified: Economic and Conservation Boon

Today scientists unveiled the first high-resolution map of the carbon stocks stored on land throughout the entire country of Perú. The new and improved methodology used to make the map marks a sea change for future market-based carbon economies. The new carbon map also reveals Perú’s extremely high ecological diversity and it provides the critical
