A new NOAA and University of Michigan study using an instrumented airplane has found unexpectedly large emissions over five major cities along the East Coast - twice the total amount of methane and almost 10 times the amount estimated from natural gas.
Carbon dioxide levels reached the highest seasonal peak recorded in 61 years of observations at NOAA's Mauna Loa observatory. This the seventh consecutive year of steep global increases in concentrations of this important greenhouse gas pollutant.
Weather conditions were ripe for a big ozone hole this year. But declining levels of ozone-depleting chemicals kept it to near-average size.
The warming influence from long-lived greenhouse gases rose again in 2017, reflecting ongoing changes to the atmosphere associated predominantly with human activities, NOAA scientists announced today.
A deep sea fishing rod is probably not the first tool that comes to mind when thinking about how to study air pollution in a remote inland desert, but it’s the heart of a new NOAA system that has given scientists a minute-by-minute look at how quickly the sun can convert oil and gas facility emissions to harmful ground-level ozone.
Spring came early this year, breaking several records at the top of the world in Barrow, Alaska, according to a new report that combines observations from NOAA, the North Slope Borough and a scientist who has tracked an Arctic bird for the last four decades.
The American Chemical Society will designate the Keeling Curve – a long-term record of rising carbon dioxide in the planet’s atmosphere -- as a National Historic Chemical Landmark in a ceremony April 30 at NOAA’s Mauna Loa Observatory in Hawaii.
A global report released this week on changing carbon dioxide levels in Earth’s atmosphere, oceans, and land environment draws heavily from data and observations by NOAA research scientists and their partners. For the first time, the annual assessment by the Global Carbon Project uses data obtained from autonomous instruments installed by NOAA scientists on its ships and other ships of opportunity and moorings to determine the variability of carbon dioxide in the surface ocean.
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.
Oceanic and Atmospheric Research (OAR) - or "NOAA Research" - provides the research foundation for understanding the complex systems that support our planet. Working in partnership with other organizational units of the NOAA, a bureau of the Department of Commerce, NOAA Research enables better forecasts, earlier warnings for natural disasters, and a greater understanding of the Earth. Our role is to provide unbiased science to better manage the environment, nationally, and globally.
