Feb. 17, 2005 --"Scientists at Scripps Institution of Oceanography at the University of California, San Diego, and their colleagues have produced the first clear evidence of human-produced warming in the world's oceans, a finding they say removes much of the uncertainty associated with debates about global warming.Quote by: SeanG
In a new study conducted with colleagues at Lawrence Livermore National Laboratory's Program for Climate Model Diagnosis and Intercomparison (PCMDI),"
"US researchers compared the rise in ocean temperatures with predictions from climate models and found human activity was the most likely cause. In coming decades, the warming will have a dramatic impact on regional water supplies, they predict."--
--"This is perhaps the most compelling evidence yet that global warming is happening right now and it shows that we can successfully simulate its past and likely future evolution," said lead author Tim Barnett, of the climate research division at the Scripps Institution of Oceanography in San Diego, California.
"If you take this data and combine it with a decade of earlier results, the debate about whether or not there is a global warming signal here and now is over at least for rational people."--
"The new ocean study, taken together with the numerous validations of the same models in the atmosphere, portends far broader changes," said Barnett. "Other parts of the world will face similar problems to those expected--and being observed now--in the western U.S. The skill demonstrated by the climate models in handling the changing planetary heat budget suggests that these scenarios have a high enough probability of actually happening that they need to be taken seriously by decision makers."--

We need to take this information in context with another recent news report...
------------------------------------------------------------------------------
--"More than 10,000 scientists, policy analysts and educators from 60 nations are expected at the meeting, which runs through Monday. At least seven sessions will touch on the relationship between science and public policy."--
--"Many researchers say they are speaking up to fight what they view as the politicization of science – efforts by industry, legislators and others to distort science to advance their agendas."--
--"In a 2003 report, the Environmental Protection Agency omitted data linking human activity to global warming."--
Sure, when left to it's own devices. We are definitely not leaving earth to it's own devices.Quote by: asterix
This reminds me of a common arguement I've heard, most memorably by Rush Limbaugh and repeated often here. It states that a single volcano produces more pollutants than all that created by humans combined.
First, volcanos have been belching forth since the earth began, and are well factored into the earth's equilibrium. What we create is on top of that.
Second, while a large volcanic eruption, say like Mt. Pinatubo, can produce around 8 to 10 million tons of pollutants in a year (pretty impressive, huh), humans are now belching forth about 30 billion tons of C02 a year... again, on top of nature's own polluters. I'll link these figures if you insist, although this would be about the 5th time I've done so.
