Lime in Oceans for CO2 Free Environment
As we know the oceans already absorb megatons of atmospheric carbon, but dash of lime - a new twist that may cut CO2 levels back to pre-industrial levels say some scientist. Scientists say they have found a workable way of reducing CO2 levels in the atmosphere by adding lime to seawater. And they think it has the potential to dramatically reverse CO2 accumulation in the atmosphere, reports Cath O’Driscoll in SCI’s Chemistry & Industry magazine published today.

The answer sounds like a cocktail recipe but it worth checking out more information about the open source project here

Maldives

It all begin when 2004 tsunami hit the Maldives islands, submerging for several minutes. Those waters retreated, but rising sea levels from global warming won’t be so transient. I saw some comments under this topic that the Dutch have been doing this for 700 years or more, as have it in UK, and peoples ask what’s new?

I just saw very interested video that shows Sydney Inundation and how Sea Level Rises video made in Google Earth on carbonplanet.com.

Sydney Inundation

The author said : I received an email the other day from Rex Rowley at Haskell Indian Nations University and the University of Kansas who pointed me to the work they have been doing with sea level rise mapping. They have Google Earth streaming data files for sea level rises of 1 to 6 meters. Their original data is red so I had to use Photoshop to make it a more pleasing blue tone, and then decided I may as well animate it together with an ominous soundtrack. I’ll make a few more of these in other cities. If anyone wants the high-res versions I’ll happily send it to you.

Glaciers And Ice Caps Dominate for the Sea Level Rise This Century.By the scientists at the National Center for Atmospheric Research (NCAR) and the University of Arizona, by 2100 the Arctic summers may be as warm as they were nearly 130,000 years ago when sea levels rose to 20 feet (6 meters) higher than they are today!! For the year 2025 the range might become from 5
to 21 inches above current sea level, while estimates of the rise by 2100 range from 2 to ll
feet. The glaciers and ice caps are currently contributing about 60 percent of the world’s ice to the oceans and it is well known now that Greenland is nowadays contributing about 28 percent of the total global sea rise from ice loss!
“One reason for this study is the widely held view that the Greenland and Antarctic ice sheets will be the principal causes of sea-level rise,” said Meier, former INSTAAR director and professor in geological sciences.
Using satellites to measure changes in elevation, Curt Davis, MU professor of electrical and computer engineering, and his team of researchers observed 7.1 million kilometers of the ice sheet for the period from 1992 to 2003. For this period they discovered that the ice sheet’s interior was gaining mass by about 45 billion tons per year, which was enough to slow sea level rise by .12 millimeters per year. NASA’s Cryospheric Processes Program and the National Science Foundation’s Antarctic Glaciology Program, suggests that increased precipitation was somehow or likely cause of the gain.
“While this is a dynamic, complex process and does not seem to be a direct result of climate warming, it is likely that climate acts as a trigger to set off this dramatic response,” said Anderson, also an INSTAAR researcher. More information on this global warming and climate changing topic here

That water, that is flowing from the North Atlantic Ocean into the Arctic provides evidence that the Arctic Ocean is warming! How the SSTs (sea surface temperatures) reflect to this global warming problem, we are trying to get after that Igor V. Polyakov’s report, made with his colleagues at the International Arctic Research Center at University of Alaska. AS Terry Gerlach from the Cascades Volcanoes Observatory in Washington state, USA says: “global volcanic CO2 output at 0.2 billion tons a year. This is less than 1% of man-made CO2 pollution.” Some third oppinion, that of Michael Storey from the Roskilde University in Denmark “There are obvious lessons from this,” he says. “The rate at which greenhouse gases are now being added to the atmosphere exceeds by far the rate of 55 million years ago,” he warns.
Half of the years after 2009 should be warmer than any time in recorded history, British scientists claim, as it was told few hours ago. That strong substained theory alarm how El Nino takes warm water from its usual home in the western Pacific and moves it to the coasts of North and South America and how this process reflect to the Pacific SSTs. The Pacific Decadal Oscillation makes high- and low-pressure zones in the atmosphere over the North Pacific flip-flop back and forth, which also causes shifts in warm and cold ocean water, as the british sciencists are continuing their long term observing of this global problem.
And..if the global warming is responsible for that increasing hurricane frequency in the North Atlantic, how come we’ve had only one tropical storm and one sub-tropical storm so far this year;is that a sign for something that may comes?!? By the Greg Holland’s of the National Center for Atmospheric Research in Boulder, Colorado circumstantial report, there is subjection between that scale of hurricanes for the last century. Holland and his colleague Peter Webster of the Georgia Institute of Technology, Atlanta ” the two hikes are clear ” (see Philosophical Transactions of the Royal Society A, DOI: 10.1098/rsta.2007.2083).
The National Science Foundation (NSF) and affiliated with the University of Wisconsin-Madison and NOAA’s National Climatic Data Center (NCDC) in Asheville, N.C., reported that “It’s going to serve a purpose as being the only globally consistent data set around. The caveat of course, is that it only goes back to 1983.”
