About the OSU College of Earth, Ocean, and Atmospheric Sciences (CEOAS): The college is renowned for research excellence and academic programs that span the earth, ocean and climate sciences, as well as the human dimensions of environmental change. CEOAS inspires scientific solutions for Oregon and the world.

Freshwater flowing into the North Pacific plays key role in North America’s climate

Massive freshwater river flows stemming from glacier-fed flooding at the end of the last ice age surged across eastern Washington to the Columbia River and out to the North Pacific Ocean, where they triggered climate changes throughout the northern hemisphere, new research published today in Science Advances shows.

Old carbon reservoirs unlikely to cause large greenhouse gas release

Carbon reservoirs found in permafrost and frozen methane hydrates have the potential to emit large quantities of methane, a potent greenhouse gas, as the planet warms, but it is unlikely the gas released from those stores will reach the atmosphere, new research published this week in Science indicates.

Methane emissions from fossil fuel industry underestimated by up to 40%, study finds

The global fossil fuel industry emits 25% to 40% more methane – a greenhouse gas and contributor to global warming – than previously thought, a study published today in Nature found.

More than 22 miles of oceanic sediment cores featured at opening of OSU repository Jan. 31

Oregon State University’s newly renovated and expanded Marine and Geology Repository, one of the nation's largest repositories of oceanic sediment cores, will officially open Jan. 31 with tours and an open house for the public.

New modeling will shed light on how policy decisions affect migration from sea level rise

A new modeling approach can help researchers, policymakers and the public better understand how policy decisions will influence human migration as sea levels rise around the globe, a paper published today in Nature Climate Change suggests.

 

Sea levels to continue rising after current Paris agreement emission pledges expire in 2030

Sea levels will continue to rise around the world long after current carbon emissions pledges made through the Paris climate agreement are met and global temperatures stabilize, a new study indicates.

Two million-year-old ice provides snapshot of Earth’s greenhouse gas history

Two million-year old ice from Antarctica recently uncovered by a team of researchers provides a clearer picture into the connections between greenhouse gases and climate in ancient times and will help scientists understand future climate change.

Large transnational corporations play critical role in global natural resource management

Researchers have identified six corporate actions that, combined with effective public policy and improved governmental regulations, could help large transnational corporations steer environmental stewardship efforts around the world, a new paper suggests.

New observations find Alaskan glacier melt rates significantly higher than predicted by theory

New acoustic observations mapping the changing face of the LeConte Glacier in southeast Alaska show that the rate of submarine melt is much higher than previously predicted by scientific theory.

Study may solve long-standing mystery of why atmospheric CO2 was lower during ice ages

A combination of sea water temperatures and iron from dust helps explain variations in atmospheric carbon dioxide levels during ice ages.
