- Climate change affecting Earth's outermost atmosphere
12-11-2006 · EurekAlert!
Carbon dioxide emissions from the burning of fossil fuels will produce a three percent reduction in the density of Earth's outermost atmosphere by 2017, scientists predict. Recent observations have shown that the thermosphere, which begins about 60 miles above Earth and extends up to 400 miles, is becoming less dense.

- First-ever study to link increased mortality specifically to carbon dioxide emissions
01-03-2008 · EurekAlert!
A Stanford scientist has spelled out for the first time the direct links between increased levels of carbon dioxide in the atmosphere and increases in human mortality, using a state-of-the-art computer model of the atmosphere incorporating scores of physical and chemical environmental processes. The new findings, to be published in Geophysical Research Letters, come to light just after the Environmental Protection Agency's recent ruling against states setting specific emission standards for this greenhouse gas.

- Scientists enhance Mother Nature's carbon handling mechanism
11-07-2007 · EurekAlert!
Taking a page from Nature herself, a team of researchers developed a method to enhance removal of carbon dioxide from the atmosphere and place it in the Earth's oceans for storage.

- Engineered weathering process could mitigate global warming
11-07-2007 · EurekAlert!
Researchers at Harvard University and Pennsylvania State University have invented a technology, inspired by nature, to reduce the accumulation of atmospheric carbon dioxide caused by human emissions. By electrochemically removing hydrochloric acid from the ocean and then neutralizing the acid by reaction with silicate rocks, the researchers say they can accelerate natural chemical weathering, permanently transferring CO2 from the atmosphere to the ocean.

- U. of Colorado study shows massive CO2 burps from ocean to atmosphere at end of last ice age
05-10-2007 · EurekAlert!
A University of Colorado at Boulder-led research team tracing the origin of a large carbon dioxide increase in Earth's atmosphere at the end of the last ice age has detected two ancient "burps" that originated from the deepest parts of the oceans.

- First-ever 'State of the Carbon Cycle Report' finds troubling imbalance
11-14-2007 · EurekAlert!
The first "State of the Carbon Cycle Report" for North America, released online this week by the US Climate Change Science Program, finds the continent's carbon budget increasingly overwhelmed by human-caused emissions. North American sources release nearly 2 billion tons of carbon into the atmosphere each year, mostly as carbon dioxide. Carbon "sinks" such as growing forests may remove up to half this amount, but these current sinks may turn into new sources as climate changes.

- Coral reefs unlikely to survive in acid oceans
12-14-2007 · EurekAlert!
Carbon emissions from human activities are not just heating up the globe, they are changing the ocean's chemistry. This could soon be fatal to coral reefs, which are havens for marine biodiversity and underpin the economies of many coastal communities. Scientists from the Carnegie Institution's Department of Global Ecology have calculated that if current carbon dioxide emission trends continue, by mid-century 98 percent of present-day reef habitats will be bathed in water too acidic for reef growth.

- New evidence of the link between carbon dioxide emissions and climate change in boreal ecosystems
02-18-2007 · EurekAlert!
New research aimed at understanding the link between carbon dioxide emissions and climate change in boreal systems has found clear links between both spring and fall temperature changes and carbon uptake/loss. Dr. Kevin Robert Gurney, assistant professor in the Earth & Atmospheric Science/Agronomy at Purdue University and associate director of the Purdue Climate Change Research Center, presented these results at the American Association for the Advancement of Science meeting in San Francisco, Calif., on December 17.

- Carbon dioxide and the ocean
03-07-2007 · EurekAlert!
Global increases in temperature are just one facet of a much larger issue that scientists at the Rosenstiel School of Marine and Atmospheric Science are dedicated to uncovering. "The Marine Inorganic Carbon Cycle," a paper recently published in the journal Chemical Reviews, attempts to quantify over 60 years of research, reviewing a vast array of science that brings into question the Earth’s natural ability to rebound from the increase in inorganic carbon dioxide in the atmosphere and oceans.

- Acid oceans warning
10-16-2007 · EurekAlert!
The world's oceans are becoming more acid, with potentially devastating consequences for corals and the marine organisms that build reefs and provide much of the Earth's breathable oxygen. The acidity is caused by the gradual buildup of carbon dioxide in the atmosphere, dissolving into the oceans. Scientists fear it could be lethal for animals with chalky skeletons which make up more than a third of the planet's marine life.
