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

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.

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

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.

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

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.
