New global assessment examines air pollutants falling on the Earth’s ...

We sat down with Richard Artz, environmental scientist at NOAA’s Air Resources Laboratory, to learn more about the new global assessment of air pollutants that fall to the earth in precipitation and in dry form. The assessment is available online in the journal Atmospheric Environment.

Carbon dioxide in the tropical Pacific Ocean is increasing faster than ...

New NOAA research has revealed unprecedented changes in ocean carbon dioxide in the tropical Pacific Ocean over the last 14 years, influencing the role the oceans play in current and projected global warming and ocean acidification. Natural variability has dominated patterns in ocean CO2 in this region, but observations now show human activity contributes to increasing CO2 levels.

Heat-trapping gas concentrations top 400 ppm, two months earlier than ...

Over the last five days beginning on March 16, 2014, carbon dioxide levels have surpassed 400 parts per million at NOAA’s Mauna Loa Observatory in Hawaii. This is nearly two months earlier than last year when the concentration of this greenhouse gas was first recorded above 400 parts per million on May 9, at the historic NOAA observatory. 

We caught up with James Butler, Ph.D., Director of NOAA’s Global Monitoring Division, to ask about what it means that we reached this milestone earlier than last year. To track carbon dioxide concentrations daily click here.
