Topic: Carbon Dioxide
Written by Alan Buis
Pasadena, CA – A team of scientists has launched a series of research flights over the remote seas surrounding Antarctica in an effort to better understand how much carbon dioxide the icy waters are able to lock away.
Called ORCAS, the field campaign will provide a rare look at how oxygen and carbon dioxide are exchanged between the air and the Southern Ocean. The campaign is led by the National Center for Atmospheric Research (NCAR). Michelle Gierach of NASA’s Jet Propulsion Laboratory, Pasadena, California, is a principal investigator, along with other scientists from a range of universities and research institutions.

Pasadena, CA – The amount of methane gas escaping from the ground during the long cold period in the Arctic each year and entering Earth’s atmosphere is likely much higher than estimated by current carbon cycle models, concludes a major new study led by San Diego State University and including scientists from NASA’s Jet Propulsion Laboratory, Pasadena, California.
On November 12th, 2015, NASA’s Carbon in Arctic Reservoirs Vulnerability Experiment (CARVE) completed its final aircraft flight.

Pasadena, CA – NASA technology is all around us, turning trash into oil, saving women from a deadly complication of childbirth, and putting the bubbles in beer.
These technologies and more, including seven connected with NASA’s Jet Propulsion Laboratory, Pasadena, California, are featured in the 2016 edition of NASA’s annual Spinoff publication, highlighting the many places NASA shows up in daily life and the aeronautics and space programs where the innovations got their start.

Pasadena, CA – People the world over are feeling, or will soon feel, the effects of the strongest El Niño event since 1997-98, currently unfolding in the eastern equatorial Pacific Ocean. New NASA satellite observations are beginning to show scientists its impact on the distribution of rain, tropospheric ozone and wildfires around the globe.
New results presented Tuesday, December 15th, at the American Geophysical Union meeting in San Francisco show that atmospheric rivers, significant sources of rainfall, tend to intensify during El Niño events, and this year’s strong El Niño likely will bring more precipitation to California and some relief for the drought.
Pasadena, CA – Mars is blanketed by a thin, mostly carbon dioxide atmosphere — one that is far too thin to keep water from freezing or quickly evaporating. However, geological evidence has led scientists to conclude that ancient Mars was once a warmer, wetter place than it is today.
To produce a more temperate climate, several researchers have suggested that the planet was once shrouded in a much thicker carbon dioxide atmosphere. For decades that left the question, “Where did all the carbon go?”
The solar wind stripped away much of Mars’ ancient atmosphere and is still removing tons of it every day. But scientists have been puzzled by why they haven’t found more carbon — in the form of carbonate — captured into Martian rocks. They have also sought to explain the ratio of heavier and lighter carbons in the modern Martian atmosphere.
NASA’s Wide-field Infrared Survey Explorer spacecraft data shows Carbon Monoxide, Carbon Dioxide in Comets

Pasadena, CA – After its launch in 2009, NASA’s NEOWISE spacecraft observed 163 comets during the WISE/NEOWISE prime mission. This sample from the space telescope represents the largest infrared survey of comets to date.
Data from the survey are giving new insights into the dust, comet nucleus sizes, and production rates for difficult-to-observe gases like carbon dioxide and carbon monoxide. Results of the NEOWISE census of comets were recently published in the Astrophysical Journal.
Tennessee Department of Agriculture says get your Tree from a Christmas Tree Farm or visit for some Natural Fun
Nashville, TN – Are you looking for a way to generate some holiday spirit that doesn’t involve a mall? Between now and Christmas, there’s no better place for an outing than a nearby Christmas tree farm. Even if you already have your tree, tree farms offer all sorts of options from wagon rides and hot chocolate to wreath-making classes and visits from Santa.
Natural trees from local tree farms are completely renewable, recyclable, 100 percent biodegradable and are close to home, leaving a negligible carbon footprint.

Washington, D.C. – Earth’s oceans and land cover are doing us a favor. As people burn fossil fuels and clear forests, only half of the carbon dioxide released stays in the atmosphere, warming and altering Earth’s climate. The other half is removed from the air by the planet’s vegetation ecosystems and oceans.
As carbon dioxide levels in the atmosphere continue their rapid, human-made rise past levels not seen for hundreds of thousands of years, NASA scientists and others are confronted with an important question for the future of our planet: How long can this balancing act continue? And if forests, other vegetation and the ocean cannot continue to absorb as much or more of our carbon emissions, what does that mean for the pace of climate change in the coming century?

Greenbelt, MD – Comet Lovejoy lived up to its name by releasing large amounts of alcohol as well as a type of sugar into space, according to new observations by an international team. The discovery marks the first time ethyl alcohol, the same type in alcoholic beverages, has been observed in a comet.
The finding adds to the evidence that comets could have been a source of the complex organic molecules necessary for the emergence of life.

Washington, D.C. – Imagine a world with extreme temperatures that can wreak havoc on unprotected spacecraft and habitat components; a world where water is so scarce that plants are outfitted with sensors so farmers can avoid overwatering them; a world where precious water supplies are found in underground oases by satellites in orbit; a world where systems filter, recycle and purify air for the survival of inhabitants huddled in shelters.
Although images of human habitation on Mars may have filled your mind, the world just described is actually Earth, and the technologies cited are spinoffs, or technologies developed by the American space program that have gone on to benefit the public.
