This visualization shows the sea level change between 1992 and 2014. Since 1992, seas around the world have risen an average of nearly 3 inches. Regional differences in sea levels are caused by ocean currents and natural long-term ocean cycles.2. Scientists estimate one-third of the ocean rise is caused by the melting of the Greenland and Antarctic ice shelves. The big concern now is that the ice sheets are ‘waking up’ to the warming climate and will contribute more and more to sea level rise in the coming decades.3. An intense research effort by NASA and others is now underway to measure and analyze how Greenland and Antarctica will respond to Earth's warmer air temperatures and the changing ocean currents along the edges of the ice shelves.TAG: Faster melting of the polar ice caps could mean sea rise of 3 feet or more by the end of the century. || NASAONAIR_Sea_Level_Rise-10-iPad3_print.jpg (1024x576) [92.3 KB] || NASAONAIR_Sea_Level_Rise-10-iPad3_searchweb.png (320x180) [67.4 KB] || NASAONAIR_Sea_Level_Rise-10-iPad3_thm.png (80x40) [5.9 KB] || NASAONAIR_Sea_Level_Rise-1_Weather_Channel_30_fps.mov (1920x1080) [493.1 MB] || NASAONAIR_Sea_Level_Rise-2_Weather_Channel_60_fps.mov (1280x720) [592.5 MB] || NASAONAIR_Sea_Level_Rise-3_NBC_Today.mov (1920x1080) [232.3 MB] || NASAONAIR_Sea_Level_Rise-4-WeatherChannel.wmv (1280x720) [8.8 MB] || NASAONAIR_Sea_Level_Rise-5-Accuweather.avi (1280x720) [6.7 MB] || NASAONAIR_Sea_Level_Rise-6_Baron_Services_MP4.mp4 (1920x1080) [23.8 MB] || NASAONAIR_Sea_Level_Rise-7_APR_422_1920_30.mov (1920x1080) [464.0 MB] || NASAONAIR_Sea_Level_Rise-8-iPad1.m4v (960x540) [13.7 MB] || NASAONAIR_Sea_Level_Rise-9-iPad2.m4v (1280x720) [7.2 MB] || NASAONAIR_Sea_Level_Rise-10-iPad3.m4v (1920x1080) [7.2 MB] || NASAONAIR_Sea_Level_Rise-10-iPad3.webm (1920x1080) [3.4 MB] || ", "hits": 73 }, { "id": 11966, "url": "https://svs.gsfc.nasa.gov/11966/", "result_type": "Produced Video", "release_date": "2015-07-31T00:00:00-04:00", "title": "A Tale Of Two Extremes Live Shots", "description": "The accumulated precipitation product visualized here begins on January 1, 2015 and runs through July 16, 2015.

As water moves around the globe — for example, due to flooding in some regions and drought in others — GRACE acts like a 'scale in the sky,' mapping the regions of Earth that are gaining or losing water each month. The GRACE mission has been particularly successful in monitoring the melting of the Greenland and Antartic ice sheets, and in mapping changing freshwater storage on land. This animation shows how the total amount of water (all of the snow, surface water, soil moisture and groundwater) varies in space and time, with the passage of dry seasons and wet seasons as well as with flooding, drought and transport due to water management Blue colors represent wetter than average conditions (relative to the 2002-2013 time period) and the red colors represent drier than average conditions. The graph at the left shows the monthly changes for the average of map region outlined in yellow. The yellow line in the graph at the left shows interannual variations.The Sacramento and San Joaquiin River basins are outlined in yellow and the rivers and their tributaries are shown by the blue lines. The basins include California's Central Valley, the most productive agricultural region in the United States. Ongoing drought in California has drained the state of nearly 15 cubic kilometers (12 miillion acre feet; 4 trillion gallons) of water in each of the last 3 years. Much of the loss is a result of groundwater depletion. Limited rainfall and snowmelt throughout the state has forced agriculture and cities to rely more heavily on groundwater reserves, resulting in rapid depletion of the aquifer beneath the Central Valley.

Orange and red shades indicate areas that lost ice mass, while light blue shades indicate areas that gained ice mass. White indicates areas where there has been very little or no change in ice mass since 2003.

The Tropical Rainfall Measurement Mission (TRMM) Multisensor Precipitation Analysis (TMPA) provides three-hourly estimates of rainfall rate across much of the globe. Here we see the seasonal cycle of monthly precipitation derived from TMPA for Africa, including the Nile Basin. The annual migration of the Intertropical Convergence Zone (ITCZ) from the Nile Equatorial Lakes region around Lake Victoria, source of the White Nile, northward into Sudan and the highlands of Ethiopia, headwaters of the Blue Nile, and back is evident in the seasonal cycle in precipitation. This precipitation cycle drives flow through the Nile River system. The Nile basin, however, is intensely evaporative, and the majority of the water that falls as rain leaves the basin as evaporation rather than river flow—either from the humid headwaters regions or from large reservoirs and irrigation developments in Egypt and Sudan. The Atmosphere Land Exchange Inverse (ALEXI) evapotranspiration product, developed by USDA scientists, uses satellite data to map daily evapotranspiration across the entire Nile basin, providing unprecedented information on water consumption. The balance of rainfall and evapotranspiration can be seen in seasonal patterns of soil moisture, as simulated by the NASA Nile Land Data Assimilation System (LDAS), which merges satellite information with a physically-based land surface model to simulate variability in soil moisture—a critical variable for rainfed agriculture and natural ecosystems. Finally, the twin satellites of the Gravity Recovery and Climate Experiment (GRACE) can be used to monitor variability in total water storage, including surface water, soil moisture, and groundwater. The annual cycle in GRACE estimates of water storage anomalies clearly shows the seasonal movement of water storage due to precipitation patterns and the movement of surface waters from headwaters regions into the wetlands of South Sudan and the reservoirs of the lower Nile basin.The Nile is the longest river in the world and its basin is shared by 11 countries. Reliable, spatially distributed estimates of hydrologic storage and fluxes can provide critical information for water managers contending with multiple resource demands, a variable and changing climate, and the risk of damaging floods and droughts. NASA observations and modeling systems offer unique capabilities to meet these information needs. || ", "hits": 80 }, { "id": 4042, "url": "https://svs.gsfc.nasa.gov/4042/", "result_type": "Visualization", "release_date": "2013-02-12T11:00:00-05:00", "title": "Freshwater Losses In The Middle East", "description": "The visualization shows variations in total water storage from normal, in millimeters, in the Tigris and Euphrates river basins, as measured by NASA's Gravity Recovery and Climate Experiment (GRACE) satellites, from January 2003 through December 2009.
