"It's" not tough to read at all, nor is it tough for me to write, as long as I have my coffee.  ;)  It looks like you're correct about the sloppiness and you have to do a little more digging into each and every link to get the correct timeline.  It was much easier to follow Cracktus' link.

My thought on global climate change is this:  With 7 billion people living all over the world, I would find it very difficult to believe that we don't have an impact on it.  I'd also bet most of it is negative.  Having said that, I still think Alaska needs a means to make revenue.  I'd like to think we could do so while trying to minimize any negative impacts.
