Alaska’s coastal waters are especially vulnerable to the drop in pH—acidification—that comes when excess carbon dioxide dissolves into the ocean from the atmosphere. These maps show relative risk levels for commerical and subsistence fisheries.
Despite uncertainties around future precipitation change, it is clear that as temperatures rise in Colorado, the state is expected to face significant challenges to managing water resources, according to a new report.
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 April 2011, Texas was in the midst of what may have been its worst fire season in history. As the season began, NOAA outlooks and observations helped fire managers think strategically about where their resources could be most effective.
