A new study suggests that Antarctica is rising in temperature, despite previous claims it was the only continent not suffering from global warming. Research in the past indicated that temperatures on much of Antarctica were staying the same or even cooling. But a review of satellite and weather records for the continent, which contains 90 percent of the world's ice and would raise world sea levels if it thaws, proves that freezing temperatures had risen by about 0.8 Fahrenheit since the...

The Environmental Protection Agency said on Friday rising seal levels on the United States' mid-Atlantic coast are happening faster than the global average because of global warming.The continued rise is threatening the future of coastal communities.The EPA released a report detailing coastal waters from New York to North Carolina have crept up by an average of 0.09 to 0.17 inches a year, compared with an average global increase of 0.07 inches a year.The report was commissioned by the Climate...

Increased rainfall on the Antarctic Peninsula is rapidly melting glaciers like the Sheldon, which has recoiled 1.2 miles in 20 years and is raising world sea levels, a leading expert announced."Rain is very corrosive to glaciers and at least in part the reason this glacier is retreating," said David Vaughan, a British Antarctic Survey glaciologist."The glacier has retreated since 1989 and left this open water. That's the same pattern for 87 percent of 400 glaciers along the Antarctic...

New research indicates that the ocean could rise in the next 100 years to a meter higher than the current sea level "“ which is three times higher than predictions from the UN's Intergovernmental Panel on Climate Change, IPCC. The groundbreaking new results from an international collaboration between researchers from the Niels Bohr Institute at the University of Copenhagen, England and Finland are published in the scientific journal Climate Dynamics.According to the UN's...

In an effort to seek clues to world ocean level rises in one of the most inaccessible places on earth, scientists are sending a yellow robot submarine to dive under an ice shelf in Antarctica. A U.S. research vessel will launch the 22 ft submarine to probe the underside of the ice at the end of the Pine Island glacier, which is moving faster than any other in Antarctica and already brings more water to the oceans than Europe's Rhine River. Large icebergs have been breaking off Antarctica's...

Satellites that were designed to measure sea level over the world's oceans can serve a valuable purpose over land, a new study has found. Researchers used NASA's TOPEX/Poseidon satellite and the European Space Agency's ENVISAT satellite to measure the height and extent of flooding in North America, South America, and Asia. The study shows that satellites can supplement the measurements that the United States Geological Survey (USGS) gathers from flood gauges on the ground -- at little or no...

Recently-reported NASA satellite data shows that Greenland, Antarctica and Alaska have shed more than 2 trillion tons of land ice since 2003. Scientists said the data collected by NASA's GRACE satellite show signs of global climate change. NASA geophysicist Scott Luthcke said more than half of the loss of landlocked ice in the past five years has occurred in Greenland, based on measurements of ice weight. That's enough melted water to fill up about 11 Chesapeake Bays, he said, and the...

As ice melts away from Antarctica, parts of the continental bedrock are rising in response -- and other parts are sinking, scientists have discovered. The finding will give much needed perspective to satellite instruments that measure ice loss on the continent, and help improve estimates of future sea level rise. "Our preliminary results show that we can dramatically improve our estimates of whether Antarctica is gaining or losing ice," said Terry Wilson, associate professor of earth sciences...

The latest image of sea-surface height measurements from the U.S./French Jason-1 oceanography satellite shows the Pacific Ocean remains locked in a strong, cool phase of the Pacific Decadal Oscillation, a large, long-lived pattern of climate variability in the Pacific associated with a general cooling of Pacific waters. The image also confirms that El Niño and La Niña remain absent from the tropical Pacific. The new image is available online at:...

Scientists have developed computer models that are useful in predicting how fast icebergs break off Antarctica and Greenland. Researchers hope the discovery will enable them to predict rising sea levels due to global warming caused by the burning of fossil fuels. "To predict the future of the ice sheet and to understand the past, we have to put the information into a computer," says Richard B. Alley, the Evan Pugh professor of geosciences at Pennsylvania State University. "The models we have...

Current Sea Level Rise
2013-04-01 10:39:21

The sea levels all around the world are rising. Current sea-level rise has the potential to affect human populations and the natural environment. Two key factors have contributed to the observed sea level rise. The first is thermal expansion: as the ocean water warms, it expands. The second is from the influence of land-based ice because of increased melting. The major store of water on land is found in the glaciers and the ice sheets. The rising of sea levels is one of several lines of...

A radar altimeter measures altitude above the terrain beneath an aircraft as opposed to a barometric altimeter which provides the distance above a pre-determined datum, usually sea level. Radar is the underpinning principle of the system. Radio waves that are reflected back from the ground are timed in order to calculate speed, distance, and time which are related to the each other and can be used to calculate the distance from one point to another. Lloyd Espenschied invented the radar...

Cthulhu
  • A gigantic fictional humanoid alien god being described with a head resembling an octopus and dragon wings and claws, around whom an insane cult developed.
  • Pertaining to the mythos of Cthulhu and additional otherworldly beings created by H. P. Lovecraft or inspired by his writings and imitators.
This word was invented in 1926 by H.P. Lovecraft for his short story, 'The Call of Cthulhu.' 'Cthulhu' may be based on the word 'chthonic,' which in Greek mythology refers to the underworld.
