Wildfire Drives Carbon Levels in Northern Forests
October 31 — Researchers simulated the carbon balance of almost 400,000 square miles of the Canadian forest over the past 60 years, to determine the relative impacts of climate and disturbance by wildfire on the forest's carbon balance. (University of Wisconsin-Madison press release) More

U.S. Fires Release Large Amounts of Carbon Dioxide
October 31 — Large-scale fires in a western or southeastern state can pump as much carbon dioxide into the atmosphere in a few weeks as the state's entire motor vehicle traffic does in a year, according to new research. (National Center for Atmospheric Research press release) More

Mineral Ages Show Blue Mountain Rocks Related to Klamath, Sierra Nevadas
October 29 — New evidence, based on mineral dating, suggests that rocks of the Blue Mountains, the oldest geological formation in Oregon, may have been derived from the Klamath and Sierra Nevada mountain chains, University of Oregon researchers report. (University of Oregon press release) More

Uncertainty and Climate Change go Hand-in-Hand
October 25 — Despite decades of ever more exacting science projecting Earth's warming climate, there remains large uncertainty about just how much warming will actually occur. (University of Washington press release) More

Agricultural Soil Erosion not Adding to Global Warming
October 25 — Agricultural soil erosion is not a source of carbon dioxide to the atmosphere, new research suggests. (University of California - Davis press release) More

"Breathable" Atmosphere Originated Half a Billion Years Ago
October 25 — Earth may have first supported an oxygen-rich atmosphere 500 million years ago when upheavals in Earth's crust initiated a kind of reverse-greenhouse effect that cooled the world's oceans, spawned giant plankton blooms and sent a burst of oxygen into the atmosphere. (Ohio State University press release) More

Study Reveals Lakes a Major Source of Prehistoric Methane
October 24 — A team of scientists has identified a new likely source of a spike in atmospheric methane coming out of the North during the end of the last ice age. (University of Alaska Fairbanks press release) More

Massive California Fires Consistent With Climate Change
October 23 — The catastrophic fires that are sweeping Southern California are consistent with what climate change models have been predicting for years, and they may be just a prelude to many more such events in the future, experts say. (Oregon State University press release) More

Decline in Uptake of Carbon Emissions Confirmed
October 23 — A decline in the proportion of carbon dioxide emissions absorbed by land and oceans is speeding up the growth of atmospheric CO2, according to new research. (CSIRO Australia) More

North Atlantic Slows on the Uptake of CO2
October 22 — Further evidence for the decline of the oceans' historical role as an important sink for atmospheric carbon dioxide is supplied by new research by environmental scientists, who have taken measurements for a decade from merchant ships plying the North Atlantic. (University of East Anglia press release) More

Green Alga Genome Project Catalogs Carbon Capture Machinery
October 11 — The analysis of a tiny green alga has uncovered hundreds of genes that are uniquely associated with carbon dioxide capture. (DOE/Joint Genome Institute press release) More

Newly Discovered Ancient African Megadroughts May Have Driven the Evolution of Humans and Fish
October 8 — From 135,000 to 90,000 years ago tropical Africa had megadroughts more extreme and widespread than any previously known for that region, according to new research that is providing insights into humans' migration out of Africa and the evolution of fish in Africa's Great Lakes. (University of Arizona press release) More

Researchers Find Evidence of Warming Climate in Ohio
October 8 — Summer nights in Ohio aren't cooling off as much as they used to, and it's likely a sign of climatic warming across the state, researchers say. (Ohio State University press release) More

Geologists Recover Rocks Yielding Insights Into San Andreas Fault
October 4 — For the first time, geologists have extracted intact rock samples from two miles beneath the surface of the San Andreas Fault, the infamous rupture that runs 800 miles along the length of California. (Stanford University press release) More

New Projections for Australia's Changing Climate
October 2 — A comprehensive assessment of Australia's climate, jointly released today, projects the changes in temperature, rainfall and other aspects of climate that can be expected over coming decades as a result of continued global emissions of greenhouse gases. (CSIRO Australia press release) More
