Bullshit

shadowcast

Did anyone catch Penn & Tellers episode of "Bullshit" on global warming? Reason is, I did some fact checking on it and there are equally interesting facts that global warming just might be over blown (Jesus I might get hammered on this). But, take into fact the studies by Univ. of Illinois on the effect it has on the ocean.

how does acidity levels prove climate change is not caused by man??

first of all - do you even believe the climate is changing (as significant parts of the world are under water now)?

Did you read the article? Do you really know what all intalls to Global warming. I mean did you look at both sides of the debate or do you just side with one side right off the bat. The ocean does not take up carbon uniformly. It breathes, inhaling and exhaling carbon dioxide. In addition to the wind-driven currents that gently stir the center of ocean basins (the waters that are most limited by stratification), the ocean’s natural, large-scale circulation drags deep water to the surface here and there. Having collected carbon over hundreds of years, this deep upwelling water vents carbon dioxide to the atmosphere like smoke escaping through a chimney. The stronger upwelling brought by the cold phase of the Pacific Decadal Oscillation apparently enhanced the size of the chimney and let more carbon escape to the atmosphere.

After 30 years of measurements (By NASA), the ocean carbon community is realizing that tracking human-induced changes in the ocean is not as easy as they thought it would be. It wasn’t a mere matter of measuring changes in carbon concentrations in the ocean over time because the natural carbon cycle in the ocean turned out to be a lot more variable than they imagined. “We discovered that natural processes play such an important role that the signals they generate can be as large as or larger than the anthropogenic signal,” says Feely. “Now we are trying to address how these decadal changes affect the uptake of carbon. Once we account for these processes, we can remove them from the data set and calculate the anthropogenic carbon dioxide as the residual.” But to track the increasingly complicated carbon balance sheet, the ocean community needed models, mathematical simulations of the natural world. Hence unknown.

i read about the first 3 paragraphs but at that point it said nothing about whether man was causing climate change ...

i've worked for the climate change centre of canada and have an environmental studies degree - take it as you see fit ...

again - nothing you posted nor what i read of the article says that man is not causing climate change - so, i ask you again: do you believe the climate is actually changing?
