Jump to Year: In press Sea-Level Rise for the Coasts of California, Oregon, and Washington: Past, Present, and Future Tide gauges show that global sea level has risen about 7 inches during the 20th century, and recent satellite data show that the rate of sea-level rise is accelerating. As Earth warms, sea levels are rising mainly because ocean water expands as it warms; and water from melting glaciers and ice sheets is flowing into the ocean. Sea-level rise poses enormous risks to the valuable infrastructure, development, and wetlands that line much of the 1,600 mile shoreline of California, Oregon, and Washington. As those states seek to incorporate projections of sea-level rise into coastal planning, they asked the National Research Council to make independent projections of sea-level rise along their coasts for the years 2030, 2050, and 2100, taking into account regional factors that affect sea level. Sea-Level Rise for the Coasts of California, Oregon, and Washington: Past, Present, and Future explains that sea level along the U.S. west coast is affected by a number of factors.
Global winds could explain record rains, tornadoes Two talks at a scientific conference this week will propose a common root for an enormous deluge in western Tennessee in May 2010, and a historic outbreak of tornadoes centered on Alabama in April 2011. Both events seem to be linked to a relatively rare coupling between the polar and the subtropical jet streams, says Jonathan Martin, a University of Wisconsin-Madison professor of atmospheric and oceanic sciences. But the fascinating part is that the change originates in the western Pacific, about 9,000 miles away from the intense storms in the U.S. midsection, Martin says. The mechanism that causes the storms originates during spring or fall when organized complexes of tropical thunderstorms over Indonesia push the subtropical jet stream north, causing it to merge with the polar jet stream. The subtropical jet stream is a high-altitude band of wind that is normally located around 30 degrees north latitude. The polar jet stream is normally hundreds of miles to the north.
Geomagnetic storm in progress! Many observers, especially in the deep south, commented on the pure red color of the lights they saw. These rare all-red auroras sometimes appear during intense geomagnetic storms. They occur some 300 to 500 km above Earth's surface and are not yet fully understood. The storm is subsiding now. Nevertheless, high-latitude sky watchers should remain alert for auroras as Earth's magnetic field continues to reverberate from the CME impact.
Science & Environment - How the world’s oceans could be running out of fish Global fish stocks are exploited or depleted to such an extent that without urgent measures we may be the last generation to catch food from the oceans. It has been some time since most humans lived as hunter-gatherers – with one important exception. Fish are the last wild animal that we hunt in large numbers.

Environment "For the global South, and especially Africa, environmental issues are not a luxury. Arresting the world's warming and protecting and restoring our natural systems are issues of life and death for much of the world's population" 2004 Nobel Peace Laureate Wangari Maathai (Kenya's Business Daily, Dec. 14, 2007) Wetropolis According to the head of Thailand’s National Disaster Warning Center, Meteorologist Smith Dharmasaroja, by 2030 much of Bangkok will lie under 1.5 meters (5 feet) of seawater. With the city sinking 10 cm below sea level, the latter rising by 40 cm annually, the safest place to create architecture is above water. Thus, a Bangkok-based architecture firm S+PBA recently unveiled drawings for a self-sustaining community that can thrive with the ebb and flow of rising tides. Dubbed “A Post Diluvian Future”, the “wetropolis” allows Bangkok to live with natural flooding instead of resisting it while creating a homeostasis that detoxifies the region’s polluted waters.
GREEN FLOAT/Shimizu's Dream - Shimizu Corporation Going Beyond CO2 Reduction to Carbon Negative To create a city that absorbs CO2 like a plant, we will employ environmental technologies to achieve a carbon negative system. Switch to a Compact City and Conversion of Industrial Structure (CO2 Reduction: About 40%) Reduce CO2 through more efficient transportation and distribution resulting from the shift to a compact city.
Vincent Callebaut Architecte LILYPAD PROGRAM : Floating Ecopolis for Climate Refugees / Mixing Uses LOCATION : Oceans SURFACE AREA : 500.000 m² PERSPECTIVES : Philippe Steels / www.pixelab.be Further to the anthropogenic activity, the climate warms up and the ocean level increases. According to the principle of Archimedes and contrary to preconceived notions, the melting of the arctic ice-floe will not change the rising of the water exactly as an ice cube melting in a glass of water does not make its level rise.
