Huge sea level rises are coming – unless we act now - environment - 25 July 2007 - New Scientist James Hansen heads NASA's Goddard Institute for Space Studies in New York. 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. in Public bookmarkswith changeclimatecryosphereicelevelmeltingriseseasheetswarnings
Losing Louisiana / Science News 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. in Public bookmarkswith changeclimatedeltalevellouisianamississippisea
NASA - Ocean Surface Topography Mission/Jason 2 Begins Mapping Oceans 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. in Public bookmarkswith changeclimateearthglobalheatlevelmappingsatellitescienceseasystemwarming
