Several years back when I first paid attention to global warming I initially wrote it off as a measurement problem largely due to urban heat islands.
Then after I read a bit and found that not to be the reason temperatures were increasing I went quickly to the other side and became very concerned about things like sea level rise. I was worried about my sister's house in Florida going under in the near following years.
With more reading I climbed down off that ladder. I found myself jerked to and fro over the next few years by someone "who had the real story" and talked a good game. And then others punched holes in their game balloon. I needed a reliable climate change warning system.
As much as I dislike some of the the things that the US military has done from time to time, I do believe that they take the job of protecting the country very seriously. And I think they have a collection of smart people along with access to the best information. I think if we were close to the edge of the cliff the Joint Chiefs would be telling us in no uncertain terms.
I've decided that as long as the military brass and the world's leading climate science organizations are not jumping up and down and screaming at us, then we've still got time to avoid the worse.
Avoid the worse, he emphasized.
