Australia's average temperature is on the rise, providing compelling evidence of the validity of climate change, claims the country's top group of scientists in a report released on Monday. The Commonwealth Scientific and Industrial Research Organization (CSIRO), in a joint "State of the Climate" report with the Bureau of Meteorology, presented findings that the country's mean temperature has increased by 0.7 degrees Celsius in the past 50 years, though some areas have experienced as much as...

Archaeologists study the challenges faced by ancients in a warming world Since 2004, University at Buffalo anthropologist Ezra Zubrow has worked intensively with teams of scientists in the Arctic regions of St. James Bay, Quebec, northern Finland and Kamchatka to understand how humans living 4,000 to 6,000 years ago reacted to climate changes. "The circumpolar north is widely seen as an observatory for changing relations between human societies and their environment," Zubrow explains, "and...

The melting of glaciers is well documented, but when looking at the rate at which they have been retreating, a team of international researchers steps back and says not so fast. Previous studies have largely overestimated mass loss from Alaskan glaciers over the past 40-plus years, according to Erik Schiefer, a Northern Arizona University geographer who coauthored a paper in the February issue of Nature Geoscience that recalculates glacier melt in Alaska. The research team, led by...

As ESA's Mission Scientist for CryoSat, Mark Drinkwater's role in supporting the preparation of the mission has been to ensure that the satellite and data processing systems are compatible with achieving the mission's objectives of deriving accurate measurements of ice-thickness change. Mark Drinkwater, a British national, trained as a geophysicist and performed early pioneering research in the use of altimeter measurements over polar ice. He currently heads the Mission Science Division at...

A 2009 claim that sea levels would rise up to 32 inches by the end of the century, is being retracted, as the original report's author says the real estimate is still not known. Scientists have discovered mistakes that undermine the projected sea level increase that would be affected by global warming. The study, published in the journal Nature Geoscience, confirmed the conclusions of a 2007 report from the Intergovernmental Panel on Climate Change. The 2009 study collected data from the...

Ice shelves are retreating in the southern section of the Antarctic Peninsula due to climate change. This could result in glacier retreat and sea-level rise if warming continues, threatening coastal communities and low-lying islands worldwide. Research by the U.S. Geological Survey is the first to document that every ice front in the southern part of the Antarctic Peninsula has been retreating overall from 1947 to 2009, with the most dramatic changes occurring since 1990. The USGS previously...

Theories about the rates of ice accumulation and melting during the Quaternary Period -- the time interval ranging from 2.6 million years ago to the present -- may need to be revised, thanks to research findings published by a University of Iowa researcher and his colleagues in the Feb. 12 issue of the journal Science. Jeffrey Dorale, assistant professor of geoscience in the UI College of Liberal Arts and Sciences, writes that global sea level and Earth's climate are closely linked. Data he...

The sea level in Israel has been rising and falling over the past 2,500 years, with a one-meter difference between the highest and lowest levels, most of the time below the present-day level. This has been shown in a new study supervised by Dr. Dorit Sivan, Head of the Department of Maritime Civilizations at the University of Haifa. "Rises and falls in sea level over relatively short periods do not testify to a long-term trend. It is early yet to conclude from the short-term increases in sea...

A major increase in maximum ocean wave heights off the Pacific Northwest in recent decades has forced scientists to re-evaluate how high a "100-year event" might be, and the new findings raise special concerns for flooding, coastal erosion and structural damage. The new assessment concludes that the highest waves may be as much as 46 feet, up from estimates of only 33 feet that were made as recently as 1996, and a 40 percent increase. December and January are the months such waves are most...

In a vivid example of how a small geographic feature can have far-reaching impacts on climate, new research shows that water levels in the Bering Strait helped drive global climate patterns during ice age episodes dating back more than 100,000 years. The international study, led by scientists at the National Center for Atmospheric Research (NCAR), found that the repeated opening and closing of the narrow strait due to fluctuating sea levels affected currents that transported heat and salinity...

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...
