Scientists find Southern Ocean removing CO2 from the atmosphere more...

CIRES-CU-NOAA led research team compile densest carbon data set in Antarctic waters

Since 2002, the Southern Ocean has been removing more of the greenhouse gas carbon dioxide (CO2from the atmosphere, according to two new studies. These studies, out today in the journals Geophysical Research Letters (GRL)and Science, make use of millions of ship-based observations and a variety of data analysis techniques to conclude that the Southern Ocean has increasingly taken up more CO2 during the last 13 years. That follows a decade from the early 1990s to 2000s, where evidence suggested the Southern Ocean CO2 sink was weakening.

New NOAA-led study measures soot from North Dakota flaring in oil and...

Flaring produces an estimated 4 tons of black carbon per day, not considered significant for climate

In the lonely reaches of northwestern North Dakota and across the border into Saskatchewan, the vast Bakken oil field hosts extensive activities to extract both crude oil and natural gas. Business is booming—production increased by 30 percent between May 2013 and May 2014. More than a quarter of the total gas produced from the Bakken operations can’t be processed fast enough, though, and the common industry practice is to flare it—burn it off as it is vented to the atmosphere. Jutting 30 feet upward like enormous lit matchsticks, the flares pose a new question for atmospheric scientists: What do the flares put into the air? A new NOAA-led study has produced the first direct measurements of how much black carbon—a major component of airborne particles that are commonly referred to as soot —is emitted by the Bakken flaring operations.

(September 1) Today NOAA released a free, downloadable flat screen version of its popular Science On a Sphere® (SOS), SOS ExplorerTM. This new way to display the dynamics of Earth’s weather and climate, plate tectonics and more will help teachers bring these stunning science visualizations, usually found at museums and science centers, into the classroom, where students can learn by exploring.


Stratosphere an Accomplice for Santa Ana Winds and California Wildfires

The hot and dry Santa Ana winds are associated with many of Southern California’s destructive wildfires, and even take the blame for tense, ugly moods. Now, NOAA researchers have found that on occasion the winds have an accomplice in contributing to California’s wildfires: atmospheric events known as stratospheric intrusions, which bring extremely dry air from the upper atmosphere down to the surface.
