Beach erosion, fisheries, oil companies and other various industries are very interested in these data. Power plants use sea water for cooling, so care about its temperature. pdboyer Tue, 14 Jul 2009 13:07:41 GMT http://climate.jpl.nasa.gov/evidence presents many lines of reasoning to support the reality of global climate change; great images and graphics pdboyer Tue, 14 Jul 2009 12:25:37 GMT http://climate.jpl.nasa.gov/SeaLevelViewer/seaLevelViewer.cfm Use of satellite ocean height data to understand Hurricane Katrina, La Nina, El Nino. Taller regions may be warmer regions. This also has implications for global warming/climate change forecasting.

A physicist and astronomer by training, he began his career studying the clouds on Venus. Since the late 1970s he has been studying and modelling the human impact on Earth's climate, and has published more than 100 papers. He entered the public spotlight in the 1980s with his outspoken testimony to congressional committees on climate change. Last year he made headlines when he spoke out against attempts by the US administration to gag climate scientists. pdboyer Tue, 30 Jun 2009 21:37:37 GMT http://www.sciencenews.org/index/generic/activity/view/id/45059/title/_Losing_Louisiana Residents of Louisiana, take note: If engineers don’t divert sediment-rich waters from the Mississippi River to help replenish a sinking river delta, about 10 percent of your state will slip beneath the waves by the end of this century. However, even if the engineers do try to abate the subsidence, the Mississippi doesn’t carry enough sediment to offset more than a small fraction of that loss, a new analysis suggests. pdboyer Tue, 30 Jun 2009 02:29:56 GMT http://www.nasa.gov/mission_pages/ostm/news/ostm-20081216.html Jason 2 satellite data shows increase of 3 mm/yr pdboyer Tue, 14 Jul 2009 13:14:58 GMT http://www.nasa.gov/mission_pages/ostm/news/ostm-20080730.html Less than a month after launch, the NASA-French space agency Ocean Surface Topography Mission (OSTM)/Jason 2 oceanography satellite has produced its first complete maps of global ocean surface topography, surface wave height and wind speed. The new data will help scientists monitor changes in global sea level and the distribution of heat in the ocean. This information is used to monitor climate change and ocean circulation, and to enable more accurate weather, ocean and climate forecasts. The data reveal patterns of sea level anomalies, which are used by scientists to calculate the speed and direction of ocean surface currents. pdboyer Tue, 14 Jul 2009 13:11:27 GMT
