There are many here that are much more knowledgeable about the science of pollution, climate change and off shore drilling her than I am but there are two facts that the media, environmentalists and the pundits seem to be unaware of:
1) Currently the world is undergoing its largest expansion, a veritable explosion, of off shore drilling and these additional leases are just not very significant in the world wide context (in fact the demand for off shore platforms is so high these fields may not get platforms for a decade).
Example: Brazil

By Alan Clendenning, Associated Press Writer
SAO PAULO, Brazil — A monster offshore oil discovery could help Brazil join the ranks of the world's major exporters, but full-scale extraction is unlikely until 2013 and will be very expensive.
The "ultra-deep" Tupi field off the coast of Rio de Janeiro could hold as much as 8 billion barrels of recoverable light crude, and initial production should exceed 100,000 barrels daily, says Guilherme Estrella, exploration and production director of Brazilian state oil company Petroleo Brasileiro (PBR).
Petrobras, as it is known, will start pilot pumping in 2010 or 2011 but full production would take several more years, Estrella said late Thursday.

On a regular basis oil exploreration is finding more and more, for example they have announced that this off shore platform has just struck oil yesterday:
RIO DE JANEIRO – OGX Petróleo e Gás Participações SA reports the find of an oil-bearing interval in the Aptian strata of well 1-OGX-8-RJS in shallower waters of Santos basin block BM-C-41 offshore Brazil. Drilling continues below the carbonate pay.
The well, named Fuji, is 82 km (51 mi) offshore state of Rio de Janeiro in 125 m (410 ft) water depth. Diamond Offshore’s Ocean Star is doing the drilling.
These off shore fields in Brazil will account for hundreds of more offshore platform operations than those off the shore of the US. They also may create a such a demand that rigs may not be available for a long time.
The second fact is that while off shore drilling represents a potential harm currently the oceans are going through a much faster chemical change by reaching a maximum absorption of CO2 increasing the accidity of the Ocean.
http://environmentalism.suite101.com/article.cfm/ocean-acidificationIt’s no secret that greenhouse gas emissions are causing global warming. But there is another equally devastating environmental consequence of humanity’s large carbon footprint that is much less widely understood: how fossil fuel emissions are changing the chemistry of the oceans.
“Ocean acidification is the ‘sleeper’ environmental issue of our time, the wet underbelly of climate change, or its evil twin,” report the filmmakers of A Sea Change (aseachange.net, FAQs), an award-winning documentary that provides a compelling overview of ocean acidification, including scientific research and a humanistic story of one family's personal concern about the future of the oceans.
The Oceans' Chemistry is Changing
According to the Energy Information Administration, slightly more than
30 billion metric tons of carbon dioxide (CO2) will be released into the air this year by vehicle exhaust and other fossil-fuel emissions (see eia.doe.gov: Figure 9: World Carbon Dioxide Emissions 2006-2030). About one-quarter of that amount will be absorbed by the oceans. ("The Ocean Carbon Cycle," Harvard Magazine, Nov./Dec. 2002) While this balancing process curbs the rate of global warming, it does come at an ecological cost.
CO2 absorption makes the seas more acidic, compromising the health and viability of the ocean's food chain, notes Victoria Fabry, an ocean biologist at the Scripps Institute of Oceanography in San Diego, California (scripps.ucsd.edu): “Essentially, you put CO2 in sea water and the pH declines and also the carbonate ion decreases, and that is a very important building block for the shells and skeletons of organisms such as corals, mussels, clams, scallops and different types of plankton.” (Scripps Oceanography at COP-15 blog; sio.ucsd.edu/cop15: posted in "ocean acidification," Jan. 5, 2010).

http://environmentalism.suite101.com/article.cfm/ocean-acidification#ixzz0jy8D3X0x Here are the facts that are frequently overlooked:
1) Whatever offshore drilling happens offshore the US will be a "drop in the ocean" compared with other offshore efforts.
2) That drilling will happen in the future.
3) Currently the oceans are absorbing about
100 million metric tons of CO2 every week. CO2 absorption is a much greater and more immediate threat to the life of the Ocean than offshore drilling so if it takes trading offshore drilling to get Senate action on CO2 reduction, EVEN IF ITS ONLY A START, it would be a trade that I would take any day of the week.
