Climate change will strongly influence human well-being through changes in food production, water availability, spread of infectious diseases, and frequency of heat waves.
This map shows the pattern of thermohaline circulation also known as "meridional overturning circulation". This collection of currents is responsible for the large-scale exchange of water masses in the ocean, including providing oxygen to the deep ocean. The entire circulation pattern takes ~2000 years.

Ocean acidification troublesLast Updated on 2012-08-09 00:00:00
The seas in which corals and other calcifying species dwell are turning acidic, their pH slowly dropping as Earth's oceans acidify in response to increased carbon dioxide in the atmosphere.
Trouble in Paradise:
Ocean Acidification This Way Comes
Sustainability of tropical corals in question, but some species developing survival mechanisms

Sea Level Rise and Coastal Flooding Impacts Viewer Last Updated on 2012-07-25 00:00:00
Sea Level Rise and Coastal Flooding Impacts Viewer
Being able to visualize potential impacts from sea level rise is a powerful teaching and planning tool, and the Sea Level Rise Viewer brings this capability to coastal communities. A slider bar is used to show how various levels of sea level rise will impact coastal communities. Completed areas include Mississippi, Alabama, Texas, Florida, and Georgia, with additional coastal counties to be added in the near future. Visuals and the accompanying data and information cover sea level rise inundation, uncertainty, flood frequency, marsh impacts, and socioeconomics.
Features of the Sea Level Rise Viewer include:
Displaying potential future sea levels
Providing simulations of sea level rise at local landmarks
Communicating the spatial uncertainty of mapped sea levels
Modeling potential marsh migration due... More »
State of the Climate in 2011Last Updated on 2012-07-11 00:00:00
Worldwide, 2011 was the coolest year on record since 2008, yet temperatures remained above the 30 year average, according to the 2011 State of the Climate report released online by the National Oceanic and Atmospheric Administration (NOAA).

NOAA-led report examines climate conditions experienced around the world
The lead character of the 2011 climate story was a double dip La Niña, which chilled the Pacific at the start and end of the year. Many of the 2011 seasonal climate patterns around the world were consistent with common side effects of La Niña. More information.

Global Sea Surface Currents and TemperatureLast Updated on 2012-07-09 00:00:00
This visualization of the world's oceans was produced using NASA/JPL's computational model called Estimating the Circulation and Climate of the Ocean, Phase II or ECCO2. ECCO2 is high resolution model of the global ocean and sea-ice. ECCO2 attempts to model the oceans and sea ice to increasingly accurate resolutions that begin to resolve ocean eddies and other narrow-current systems which transport heat and carbon in the oceans.The ECCO2 model simulates ocean flows at all depths, but only surface flows are used in this visualization. There are 2 versions provided: one with the flows colored with gray, the other with flows colored using sea surface temperature data. The sea surface temperature data is also from the ECCO2 model. The dark patterns under the ocean represent the undersea bathymetry. Topographic land exaggeration is 20x and bathymetric exaggeration is... More »
Bathymetric Data ViewerLast Updated on 2012-05-10 13:46:21
NOAA has made sea floor maps and other data on the world’s coasts, continental shelves, and deep ocean available for easy viewing online through its Bathymetric Data Viewer. Anyone with Internet access can now explore undersea features and obtain detailed depictions of the sea floor and coasts, including deep canyons, ripples, landslides, and likely fish habitat.
The new online data viewer compiles sea floor data from the near shore to the deep blue, including the latest high-resolution bathymetric (sea bottom) data collected by NOS’s Office of Coast Survey primarily to support nautical charting.
“NOAA’s ocean bottom data are critical to so many mission requirements, including coastal safety and resiliency, navigation, healthy oceans and more. They are also just plain beautiful,” said Susan McLean, chief of NOAA’s Marine Geology and... More »
