Ocean waves slowly eat away coastal cliffs the world over, but in parts of Alaska, these processes have accelerated due to changing climate. These photos document a cliff collapse near Drew Point in the late 2000s.
Add a new item to the list of things that have migrated in response to climate change: the latitude where hurricanes reach their maximum intensity. The shift was accompanied by increasing vertical wind shear near the equator.
Since 2004, researchers in NOAA’s Global Monitoring Division have released the Annual Greenhouse Gas Index: a single value that compares the total warming effect of each year's concentrations of heat-trapping gases to 1990 levels.
In response to recent decades' warming, forests in the eastern United States have been "inhaling" more carbon dioxide through photosynthesis than they've “exhaled” through respiration.
CarbonTracker is a tool for modelling sources and sinks of carbon dioxide. Users can download the code, carbon dioxide data, and the tool's carbon flux estimates to conduct their own analyses or to help improve the system.
Jeanine Jones, Interstate Resources Manager for the California Department of Water Resources, talks about the state's ongoing drought conditions and planning for California's water future.
Ocean water acidified by increasing carbon dioxide is corroding calcium carbonate minerals—an essential ingredient for shell- and skeleton-building that creatures like this tiny snail rely upon.
A lack of snow covering the harsh terrain of the Iditarod this March made the 2014 race especially challenging, and many mushers pulled out of the race due to injuries and broken sleds.
