Latest Future sea level Stories

Sea levels around the world can be expected to rise by several meters in coming centuries, if global warming carries on The study is the first to give a comprehensive projection for this long perspective, based on observed sea-level rise over the past millennium, as well as on scenarios for future greenhouse-gas emissions. "Sea-level rise is a hard to quantify, yet critical risk of climate change," says Michiel Schaeffer of Climate Analytics and Wageningen University, lead author of the...

Novel Method To Identify Sources Of Global Sea Level Rise
2012-04-24 11:08:34

As the Earth's climate warms, a melting ice sheet produces a distinct and highly non-uniform pattern of sea-level change, with sea level falling close to the melting ice sheet and rising progressively farther away. The pattern for each ice sheet is unique and is known as its sea level fingerprint. Now, a group of geophysicists from the University of Toronto, Harvard and Rutgers Universities have found a way to identify the sea level fingerprint left by a particular ice sheet, and possibly...

Image 1 - Global Sea Level Could Rise As Much As 70 Feet In The Future

Scientists looked back in time - in the geologic record - to see the future Even if humankind manages to limit global warming to 2 degrees Celsius (3.6 degrees Fahrenheit)--as the Intergovernmental Panel on Climate Change (IPCC) recommends--future generations will likely have to deal with a completely different world. One with sea levels 40 to 70 feet higher than at present, according to research results published this week in the journal Geology. The scientists, led by Kenneth...

Image 1 - Paleoclimate Record Points Toward Potential Rapid Climate Changes
2011-12-10 04:29:55

New research into the Earth's paleoclimate history by NASA's Goddard Institute for Space Studies director James E. Hansen suggests the potential for rapid climate changes this century, including multiple meters of sea level rise, if global warming is not abated. By looking at how the Earth's climate responded to past natural changes, Hansen sought insight into a fundamental question raised by ongoing human-caused climate change: "What is the dangerous level of global warming?" Some...

NASA researchers have created the first complete map of the speed and direction of ice flow in Antarctica. The space agency said the map will be critical for tracking future sea-level increases from climate change. The researchers created the map using integrated radar observations from a consortium of international satellites. "This is like seeing a map of all the oceans' currents for the first time. It's a game changer for glaciology," Eric Rignot of NASA's Jet Propulsion Laboratory in...

WASHINGTON, Aug. 18, 2011 /PRNewswire-USNewswire/ -- NASA-funded researchers have created the first complete map of the speed and direction of ice flow in Antarctica. The map, which shows glaciers flowing thousands of miles from the continent's deep interior to its coast, will be critical for tracking future sea-level increases from climate change. The team created the map using integrated radar observations from a consortium of international satellites. (Logo:...

A consistent link exists between changes in global mean surface temperature and sea level, resulting in a greater rate of sea-level rise along the U.S. Atlantic coast than that of the past 2,000 years, says an international research team. "Sea-level rise is a potentially disastrous outcome of climate change, as rising temperatures melt land-based iced and warm ocean waters," says Benjamin Horton, associate professor and director of the Sea Level Research Laboratory at the University of...

Ice sheets have been losing mass at an accelerated rate over the past two decades, and these changes could soon become the dominant contributor to rising global sea levels, a NASA-funded study has discovered. The results of the nearly 20-year satellite research project--the longest study ever to track changes in polar ice sheet mass--showed that ice sheets in Greenland and the Antarctic lost an average of 475 gigatons of combined mass annually. Each gigaton is roughly equal to 2.2 trillion...

Hotter summers may not be as catastrophic for the Greenland ice sheet as previously feared and may actually slow down the flow of glaciers, according to new research. A letter published in Nature on 27 January explains how increased melting in warmer years causes the internal drainage system of the ice sheet to 'adapt' and accommodate more melt-water, without speeding up the flow of ice toward the oceans. The findings have important implications for future assessments of global sea level...


Word of the Day
omphalos
  • The navel or umbilicus.
  • In Greek archaeology: A central boss, as on a shield, a bowl, etc.
  • A sacred stone in the temple of Apollo at Delphi, believed by the Greeks to mark the 'navel' or exact center-point of the earth.
'Omphalos' comes from the ancient Greek.
