As Alaska warms, methane emissions appear stable

Analysis of nearly three decades of air samples from Alaska’s North Slope shows little change in long-term methane emissions despite significant Arctic warming over that time period, according to new research published in Geophysical Research Letters.

Q&A: What do Arctic ice and Atlantic hurricanes have in common?

The journal Nature Geoscience published a paper by Tom Delworth and his colleagues examining how a natural atmospheric force--the North Atlantic Oscillation--may be changing ocean currents in the North Atlantic. Among other impacts, the stronger ocean currents increase the amount of heat flowing toward polar areas, which could speed up Arctic ice melt and affect how hurricanes form. We asked Delworth a few questions about his study:

South Pole is the last place on Earth to pass a global warming milestone

South Pole is the last place on Earth to pass a global warming milestone

The Earth passed another unfortunate milestone May 23 when carbon dioxide (CO2) surpassed 400 parts per million (ppm) at the South Pole for the first time in 4 million years.

Milky Way now hidden from one ­third of humanity

The Milky Way, the brilliant river of stars that has dominated the night sky and human imaginations since time immemorial, is but a faded memory to one third of humanity and 80 percent of Americans, according to a new global atlas of light pollution produced by Italian and American scientists.

NOAA invests $4.5 million to improve ocean observations for weather and climate prediction

NOAA’s Climate Program Office announced today that it is investing $4.5 million in four projects to test technology designed to improve the Tropical Pacific Observing System, an array of buoys in the tropical Pacific used to better understand El Niño Southern Oscillation (ENSO), how it develops, and how it affects Earth’s weather.

Scientists deploy autonomous sailing vessels to study whales, fish and seals

NOAA Research and NOAA Fisheries have teamed up with academic and private sector partners to test innovative technologies that, if successful, will enable researchers to gather information on ocean conditions and marine species in remote areas of the ocean that are costly to reach and difficult to study.  

New study: Sea ice loss likely no factor in cold Northern Hemisphere winters

New study: Sea ice loss likely no factor in cold Northern Hemisphere winters

The rapid loss of Arctic sea ice is a major driver of the warming trend sweeping across the Arctic in recent  years, but melting sea ice is probably not behind recent cold winters in parts of Europe, Asia, and the United States, according to a new NOAA study.
Arctic set for record-breaking melt this summer

Arctic set for record-breaking melt this summer

The record heat baking Alaska is poised to smash a host of climate records in 2016, including the earliest snowmelt date at NOAA’s Barrow Observatory, the northernmost point in the nation.


Warming due to carbon dioxide jumped by half in 25 years

Warming due to carbon dioxide jumped by half in 25 years

Human activity  has increased the direct warming effect of carbon dioxide (CO2) in the atmosphere by 50 percent above pre-industrial levels during the past 25 years, according to NOAA's 10th Annual Greenhouse Gas Index .


North Dakota’s Bakken oil and gas field leaking 275,000 tons of methane per year

North Dakota’s Bakken oil and gas field leaking 275,000 tons of methane per year

The Bakken oil and gas field is leaking a lot of methane, but less than some satellites report, and less than the latest Environmental Protection Agency inventory for petroleum systems, according to the researchers’ calculations. That's the finding of the first field study measuring emissions of this potent greenhouse gas from the Bakken, which spans parts of North Dakota and Montana. The work was published today in the Journal of Geophysical Research: Atmospheres
