Quoting Chuck Hards <chuck.hards@gmail.com>:
Nobody on this list (that I'm aware of, anyway, my apologies if someone here is doing the science) is a practicing environmental scientist with the means to conduct meaningful research on the causes of global warming.
Well, no, but I do have some recent experience. Let me shine a different more personal light on the subject. Anyone who has ever been to Blue Lake diving knows that it is a thermal lake. The average temperature of the water is 72-78 degrees year round. The underwater weed beds are thick and healthy. They are teaming with largemouth bass and bluegills. There is a large population of fresh water sponges that grows on everything near the numerous bubbling and rolling thermal hot pots that litter the bottom. It had been 4 years since I last visited the lake, but this past week when I went back out to dive, something had changed. The lake didn't look the same. The walk to the lake was more swamp than I recall. Upon doing a "classic" slip and fall entry into the water it became very apparent that the water temperature had changed. The computer said 57 degrees. Underwater, the horror unfolded as I swam looking for something familiar. The once healthy weed beds were all but gone, and there were no huge blugills or bass. There is a fair population of small fry though, but that is about it. Most of the really big underwater thermal rivers and hot pots are now quiet. I couldn't see any sponges. The bottom of the lake looked like a moonscape and deep with silt. The slightest fin kick brought forth a cloud of thick silt that blocked out the view. Even the depth had changed. In disbelief I did a controlled emergency swimming ascent and through my regulator yelled "Why God why???" And then it hit me, I was in the wrong lake. Okay that's my global warming experience. Anyone care to share?
