It is absurd to use ten years of data to predict climate trends. Let me show you what I mean:Skyhunter said:This graph shows a warming trend in the Bering Sea.

The timeline is 722 pixels tall and it represents 2 billion years of history. One pixel is therefore about 2.8 million years of time. That red line is one pixel wide. Does that put things in perspective?
A graph may look like this:

...but when it is put on our two billion year timeline, it looks like this:

Can you see it? It is the same blue line as the graph above, but put on the same scale as the two billion year timeline (and I am even being generous with one pixel, it should be about 1/7th of a pixel). The Earth's recent timeline may show abrupt changes in climate, but in the grand scheme of things - millions and billions of years - abrupt changes in climate are only microscopic deviations from a very well-defined curve.
Now, I am not ruling out the possibility that human emissions are to blame for observed warming trends, I have no way to make an absolute judgment. This is why I am so disturbed when a person makes a statement of fact one way or the other.
And on a less serious note:
Looking at http://www.clearlight.com/~mhieb/WVFossils/PageMill_Images/image160.gif one can see that, 10,000 years ago, uncivilized man's SUVs, coal power plants, aggressive deforestation and campfires were enough to cause drastic climate change over a short time.
