2015 Sets a Record Low for Antarctic Ozone Hole in October

NOAA’s measurements of ozone at South Pole registered a record low for the month of October. This year, the average amount of ozone measured by a Dobson instrument at South Pole in the second half of October was 114 Dobson Units (DU), or 60 percent below the pre-ozone hole conditions.

Scientists find Southern Ocean removing CO2 from the atmosphere more efficiently

Since 2002, the Southern Ocean has been removing more of the greenhouse gas carbon dioxide (CO2) from the atmosphere, according to two new studies. These studies 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.

Measuring methane loss in Texas' Barnett Shale

About 170,000 pounds (76,000 kg) of the greenhouse gas methane leak per hour from the Barnett Shale region of Texas, including the urban areas of Dallas and Fort Worth, according to a new study led by NOAA/ESRL and Cooperative Institute for Research in Environmental Sciences (CIRES) researchers.

Bottled air from all over the world tells story of ozone-depleting gases and their connection to climate change

If you’re like me, when you hear the word “flask,” you’re likely to picture a grizzled, trail-weary cowboy gulping down a mouthful of whiskey from a tarnished, dented tin. But say “flask” to atmospheric chemist Steve Montzka, and he sees something more like a fire extinguisher or a stainless steel, two-liter soda bottle.
Recent adjustments to the Montreal Protocol help protect ozone layer, but newer chemicals contribute to warming

Recent adjustments to the Montreal Protocol help protect ozone layer, but newer chemicals contribute to warming

An international agreement in 2007 to deal with the last remaining ozone-depleting chemicals used in large quantities is working, according to a new analysis published today. Atmospheric emissions of those chemicals, called hydrochlorofluorocarbons (HCFCs) and used in refrigeration and air conditioning, are no longer increasing, after having increased consistently over the past few decades, according to NOAA measurements published in the Journal of Physical Chemistry

Greenhouse gas benchmark reached

For the first time since we began tracking carbon dioxide in the global atmosphere, the monthly global average concentration of this greenhouse gas surpassed 400 parts per million in March 2015, according to NOAA’s latest results.

Scientists probe methane mystery in Four Corners

A team of scientific investigators is now in the Four Corners region of the U.S. Southwest, an area where the states of Arizona, New Mexico, Colorado and Utah meet at one point, aiming to uncover reasons for a mysterious methane hotspot detected from space by a European satellite. The joint project is working to solve the mystery from the air, on the ground, and with mobile laboratories.
