Surprisingly large carbon uptake by North American biosphere during El Niños

New analysis of NOAA’s long-term air samples by NOAA and CIRES scientists finds that the North American terrestrial biosphere takes up unexpectedly large amounts of carbon in response to elevated carbon dioxide levels during El Niño years.

Carbon dioxide levels hit record peak in May

Atmospheric carbon dioxide continued its rapid rise in 2019, with the average for May peaking at 414.7 parts per million at NOAA’s Mauna Loa Atmospheric Baseline Observatory, scientists from NOAA and Scripps Institution of Oceanography at the University of California San Diego announced today.

US methane emissions flat since 2006 despite increased oil and gas activity: study

Natural gas production in the United States has increased 46 percent since 2006, but there has been no significant increase of total US methane emissions and only a modest increase from oil and gas activity, according to a new NOAA study.

Global carbon dioxide growth in 2018 reached 4th highest on record

By the end of 2018, NOAA’s atmospheric observatory at Mauna Loa recorded the fourth-highest annual growth in the concentration of atmospheric carbon dioxide (CO2) in 60 years of record-keeping.

Study sheds light on persistent gap in natural gas methane emissions measurements

It’s a question that’s puzzled policymakers, researchers and regulatory agencies for years: How much methane is being emitted from natural gas operations across the U.S.? And why have the two main estimation methods applied across U.S. oil and gas basins always seem to disagree?

Photo feature: A ‘welcoming’ sun returns to the South Pole

The fall equinox means the end of summer for the Northern Hemisphere, but marks the beginning of spring — and the first glimpse of the sun since March — for scientists at NOAA’s South Pole Atmospheric Baseline Observatory located at the Amundsen-Scott South Pole Research Station.

Another climate milestone on Mauna Loa

Carbon dioxide levels measured at NOAA’s Mauna Loa Atmospheric Baseline Observatory averaged more than 410 parts per million in April and May, the highest monthly averages ever recorded, scientists from NOAA and Scripps Institution of Oceanography at the University of California San Diego announced today.

NOAA’s greenhouse gas index up 41 percent since 1990

NOAA’s Annual Greenhouse Gas Index, which tracks the warming influence of long-lived greenhouse gases, has increased by 41 percent from 1990 to 2017, up 1 percent from 2016 -- with most of that attributable to rising carbon dioxide levels.

Emissions of ozone-destroying chemical controlled by Montreal Protocol rising again, NOAA data shows

Emissions of one of the chemicals most responsible for the Antarctic ozone hole are on the rise, despite an international treaty that required an end to its production in 2010, a new NOAA study shows.
