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?

New research examines the North Atlantic Oscillation and its influence on global weather

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:

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.
