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. However, there are two huge ice reservoirs that are not on the water and whose melting will transfer their volume towards the oceans, leading to their rising. It deals with the ice caps of Antarctic and Greenland on the one hand, and the continental glaciers on the other hand. Another reason of the ocean rising, that does not have anything to do with the ice melting is the water dilatation under the effect of the temperature. 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. Energy Conservation (CO2 Reduction: About 30%) At 1,000m above the equator, the temperature is around a comfortable 26°C. Power Generation Using Natural Energy (CO2 Reduction: About 30%) We will fully employ a range of natural energy sources including space solar power satellites, ocean thermal energy conversion, waves, wind and solar power.

CO2 Recovery and Ocean Sequestration (CO2 Reduction: About 30%) The CO2 absorption capacity of the ocean is thought to be orders of magnitude greater than terrestrial forests. A Bustling Botanical City Where People Live in a Harmonious Balance with Nature. 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.

Wetropolis

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. Courtesy of S+PBA The project examines the entirely supra-marine stilt home community of Koh Pan Yii, a settlement that floats on the Andaman sea in Southern Thailand, successfully sustaining all of the typical functions of an urban community—schools, public spaces, hospitals, utilities, industry.

Silent Ocean - Perspectives on Ocean Science. 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.

La hausse du niveau de la mer devrait être bien plus importante que prévu. L'élévation du niveau de la mer due au réchauffement climatique pourrait se révéler deux à trois fois plus importante que prévu au cours de ce siècle, indique une étude publiée vendredi 22 juin par le Conseil national de la recherche américain.

La hausse du niveau de la mer devrait être bien plus importante que prévu

Les experts se sont penchés sur des estimations des Nations unies et les ont mises à jour avec de nouvelles données concernant l'état de la calotte glaciaire, dont la fonte serait responsable de l'accélération de la montée du niveau des océans. Dans leur étude, ils prévoient une montée des eaux tout autour du globe allant de 8 à 23 cm d'ici 2030, par rapport au niveau de 2000, de 18 à 48 cm d'ici 2050, et de 50 cm à 1,40 m d'ici 2100.

Cette dernière estimation est nettement supérieure à celle avancée par le Groupe d'experts des Nations unies sur l'évolution du climat (GIEC) dans leur rapport de 2007. A l'époque, le GIEC avait tablé sur une hausse de 18 à 59 cm d'ici la fin du XXIe siècle. Prospective en Océan Atmosphère 2006-2011.

Ocean Acidification, Today and in the Future. « Le futur des océans est entre nos mains à tous » selon N. Guichoux (Dir. Europe label MSC) 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. And yet, we may be the last generation to do so.

Entire species of marine life will never be seen in the Anthropocene (the Age of Man), let alone tasted, if we do not curb our insatiable voracity for fish. Last year, global fish consumption hit a record high of 17 kg (37 pounds) per person per year, even though global fish stocks have continued to decline. Around 85% of global fish stocks are over-exploited, depleted, fully exploited or in recovery from exploitation. Large areas of seabed in the Mediterranean and North Sea now resemble a desert – the seas have been expunged of fish using increasingly efficient methods such as bottom trawling.
