Gina Hebert, Marine Biological Laboratory What do mollusks, starfish, and corals have in common? Aside from their shared marine habitat, they are all calcifiers — organisms that use calcium from their environment to create hard carbonate...

Latest Carbon dioxide in Earth's atmosphere Stories

2014-07-07 09:45:20

UC San Diego Biologists at UC San Diego have solved a long-standing mystery concerning the way plants reduce the numbers of their breathing pores in response to rising carbon dioxide levels in the atmosphere. In a paper published in this week’s early online edition of Nature, they report the discovery of a new genetic pathway in plants, made up of four genes from three different gene families that control the density of breathing pores—or “stomata”—in plant leaves in response...

University of Bristol The impact of the greenhouse gas CO2 on the Earth's temperature is well established by climate models and temperature records over the past 100 years, as well as coupled records of carbon dioxide concentration and temperature throughout Earth history. However, past temperature records have suggested that warming is largely confined to mid-to-high latitudes, especially the poles, whereas tropical temperatures appear to be relatively stable: the tropical thermostat...

Warming Climates Intensify Carbon Dioxide Given Out By Oceans
2014-06-09 03:23:28

University of Edinburgh Rising global temperatures could increase the amount of carbon dioxide naturally released by the world's oceans, fueling further climate change, a study suggests. Fresh insight into how the oceans can affect CO2 levels in the atmosphere shows that rising temperatures can indirectly increase the amount of the greenhouse gas emitted by the oceans. Scientists studied a 26,000-year-old sediment core taken from the Gulf of California to find out how the ocean's...

explaining the Last Glacial Maximum
2014-06-03 05:48:44

redOrbit Staff & Wire Reports - Your Universe Online A team of MIT scientists has turned to the Southern Ocean in search of an explanation for the Last Glacial Maximum (LGM), a period in the Earth's climate history during which the northern continents were covered by ice sheets, according to new research appearing in the Proceedings of the National Academy of Sciences. Plankton fossils in deep-sea sediments contain chemical traces that reveal rearranged ocean water masses, as well...

Dryland Ecosystems Emerge As Driver In Global Carbon Cycle
2014-05-22 03:17:36

Montana State University Dryland ecosystems, which include deserts to dry-shrublands, play a more important role in the global carbon cycle than previously thought. In fact, they have emerged as one of its drivers, says Montana State University faculty member Ben Poulter. Surprised by the discovery, Poulter and his collaborators explained their findings in Nature. At the same time, they urged global ecologists to include the emerging role of dryland ecosystems in their research. Nature...

How Does Your Garden Glow?
2014-05-06 03:02:17

By Laurie J. Schmidt, NASA's Jet Propulsion Laboratory Science is full of serendipity -- moments when discoveries happen by chance or accident while researchers are looking for something else. For example, penicillin was identified when a blue-green mold grew on a Petri dish that had been left open by mistake. Now, satellite instruments have given climate researchers at NASA and other research institutions an unexpected global view from space of a nearly invisible fluorescent glow that...

NASA's Orbiting Carbon Observatory-2 Satellite Arrives At Launch Site
2014-05-02 03:28:08

NASA's Jet Propulsion Laboratory A NASA spacecraft designed to make precise measurements of carbon dioxide in Earth's atmosphere is at Vandenberg Air Force Base, Calif., to begin final preparations for launch. The Orbiting Carbon Observatory-2 arrived Wednesday at its launch site on California's central coast after traveling from Orbital Sciences Corp.'s Satellite Manufacturing Facility in Gilbert, Ariz. The spacecraft now will undergo final tests and then be integrated on top of a...

Antarctica Was A Balmy 72 Degrees Fahrenheit During The Eocene
2014-04-22 13:07:31

Brett Smith for redOrbit.com - Your Universe Online Previous studies have shown that Antarctica was a much warmer continent 40 to 50 million years ago and a new report from a team of American, Dutch and Australian researchers has revealed finer details on the milder temperature that blanketed the region at the time. Published on Monday in the Proceedings of the National Academy of Sciences, the new report revealed that parts of Antarctica were as warm as Coastal California and sea...

By Carol Rasmussen, NASA Earth Science News Team Simply by breathing, humans have played a small part in the planet-wide balancing act called the carbon cycle throughout our existence. However, in the last few hundred years, we have taken a larger role. Our activities, such as fossil fuel burning and deforestation, are pushing the cycle out of its natural balance, adding more and more carbon dioxide to the atmosphere. Natural processes are working hard to keep the carbon cycle in...

long term warming trend
2014-03-11 12:20:13

WASHINGTON, March 11, 2014 /PRNewswire-USNewswire/ -- A new NASA study shows Earth's climate likely will continue to warm during this century on track with previous estimates, despite the recent slowdown in the rate of global warming. This research hinges on a new and more detailed calculation of the sensitivity of Earth's climate to the factors that cause it to change, such as greenhouse gas emissions. Drew Shindell, a climatologist at NASA's Goddard Institute for Space Studies in New...
