Includes sea level rise; extreme weather; changes to ecosystems, plants and animals; melting ice and permafrost; ocean wamring; impacts to water resources, agriculture, public health and national security
Models project that extreme dust events combined with global warming could advance the spring thaw in the mountains of the Upper Colorado River Basin by as many as 6 weeks by 2050. The earlier disappearance of snow could amplify water disputes, extend the fire season, and stress aquatic ecosystems.
Stunned by Sandy's devastation, the city of New York undertook an ambitious project: to update its long-term sustainability plan using the latest climate science. Their goal was to understand how much sea level could rise, how soon, and just how vulnerable the city would be if some of the more extreme climate change projections turn into reality.
Developed by the NOAA Coastal Services Center, the sea level rise viewer offers access to data and information about the risks of sea level rise, storm surge, and flooding along the coastal United States. The Web-based map has the potential to help people build (or rebuild) in a more resilient way.

Since 2002, Octobers in Barrow, Alaska—America's northernmost town—are regularly near the warmest on record, thanks to the retreat of sea ice. The warming hinders traditional hunting activities, makes the town more vulnerable to storm surge flooding, and thaws the frozen ground to greater depths, which destabilizes roads, house foundations, and traditional underground freezers.
Maps of changes in the saltiness of the surface waters of the ocean over time can reveal natural climate cycles, human-caused changes in evaporation and rainfall, and variation in the strength and location of currents. This map of changes in surface salinity between 2004 and 2012 provides clues to how climate variabiity and change have influenced the global water cycle in the past decade.
The Spring Outlook encompasses temperature, precipitation, drought, and flooding expectations for the coming three months, and Mike Halpert, Acting Director of the Climate Prediction Center, discusses the outlook and its implications.
