Do You Want to avoid Warming..! Just lock CO2 in rocks

Co2 warming
We know well that entire world community is worried about rising warming level of the earth and our scientist community is obsess with various potential solution to at least get some break.In a major such a effort was made recently this year in Iceland.

Earlier in this year, on the steaming fringes of an Icelandic volcano, an international team of scientists will begin pumping "seltzer water" into a deep hole, producing a brew that will lock away carbon dioxide forever. Chemically disposing of CO2,the chief greenhouse gas blamed for global warming, is a kind of 21st-century alchemy that researchers and governments have hoped for to slow or halt climate change.

The American and Icelandic designers of the "CarbFix" experiment will be capitalizing on a feature of the basalt rock underpinning 90% of Iceland: It is a highly reactive material that will combine its calcium with a CO2 solution to form limestone - permanent, harmless limestone. Researchers caution that their upcoming 6-to-12-month test could fall short of expectations, and warn against looking for a climate "fix" from CarbFix any year soon.

In fact, one of the objectives of the project, whose main sponsors are Reykjavik's city-owned utility and US and Icelandic universities, is to train young scientists for years of work to come. A scientific overseer of CarbFix - the man, as it happens, who also is credited with coining the term "global warming" four decades ago - says the world's failure to heed those early warnings, to rein in greenhouse-gas emissions from coal, gasoline and other fossil fuels, is driving scientists to drastic approaches.

"Whether we do it in the next 50 years, or the 50 years after that, we're going to have to store CO2," Columbia University's Wallace S Broecker said in an interview in New York. The world is already storing some CO2. As a byproduct of Norway's natural gas production, for example, it is being pumped into a sandstone reservoir beneath the North Sea. But people worrysuch stowed-away gas could someday escape, while CO2 transformed into stone would not. The experiment will take place below the landscape of this place 29 kilometers southeast of Reykjavik.

The experiment leads various enthusiastic and of course serious question like, would such practices if followed world wide,pose a potential threat for entire planet. What could be its potential consequence if anything goes wrong.Only time will clear the picture and the scope of the experiment.
