Research shows ocean acidification is spreading rapidly in the Arctic
Ocean acidification is spreading rapidly in the western Arctic Ocean in both area and depth, potentially affecting shellfish, other marine species in the food web, and communities that depend on these resources, according to new research published in Nature Climate Change by NOAA, Chinese marine scientists and other partners.
Q&A: Is Arctic warming fueling severe winter weather in the mid-latitudes?
We caught up with James Overland, oceanographer at NOAA's Pacific Marine Environmental Lab, to hear about his latest research on whether Arctic warming is fueling more severe winter weather in the mid-latitudes, the temperate zone of the Earth between the tropics and the Arctic, and the part of the United States where most Americans live.
NOAA is transforming science with unmanned systems
At first glance they might be mistaken for toys, but these remote-controlled devices aren't for play. Unmanned aircraft and watercraft are being put to work by NOAA scientists to gather astonishing new data from our wildlands and waterways.
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:
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
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
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.
NOAA's Science On a Sphere® animations coming to your desktop
(September 1) Today NOAA released a free, downloadable flat screen version of its popular Science On a Sphere® (SOS), SOS ExplorerTM. This new way to display the dynamics of Earth's weather and climate, plate tectonics and more will help teachers bring these stunning science visualizations, usually found at museums and science centers, into the classroom, where students can learn by exploring.
Recording climate change from the top of the world
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.
