Real Problem?

This is an interesting little 26 second look at 131 years of global warming. Depending on you viewpoint, it may be pure fantasy or a hard look at where were came from and where we're headed.
Take a look---and also look at the comments (still growing) below the video.

The tough part for me was seeing that things were pretty good when I was a young lad--early 50's--AND even into the 60's and 70's---then the warming started accelerating. The last 20 years are disturbing to see. Normal climate cycle? Variation in sun's intensity? Perhaps, but evidence otherwise is substantial. 


What if the warming is being caused by human activities? Is sustaining the sanctity of the institutions and governments worth the grave risks associated with a failure to seriously address the possibility and take all appropriate actions? The institutions seem to believe so--their actions speak quite loudly.
