30% more acidic! :shock: I wonder what 30% means; isn't pH a log scale?

Valid point Monty, but to put it in perspective, if I was to turn around and reduce your salary (or increase your taxes) by 30% you'd cry foul.

30% is 30%, whatever scale you operate on.

Talk about your selection pressure, could this usher in the age of the nudibranch?
Interesting that you should make that suggestion as a diver/collector I work with has mentioned seeing a major colony of some of the nudis that they had only seen on rare occassions and are not listed as a Caribbean species.

Really? There could be a whole range of reasons for that but its a bit spooky. I reckon I am seeing much more green algae when i dive these days (than when I started in the 70's) but I put that down to fertilizers and maybe climate change.

Who knows how much of an impact we are going to have on evolution and what the higher life forms in 10,000 years will make of us. Lets hope its not all negative, but I do worry.

There seems to be a lot of "invasions" occuring right now. One of the most feared on our East Coast is the large and growing population of Lionfish. Some of the news print attributes it to a personal aquarium that held 6 of them that were freed during a hurricane. I don't hold much to that idea, especially since they seem to be coming from the Bahammas and suspect more of a migration like we are seeing with the Humbolt squid. Not only do we not know if global warming, farming run-off and over-fishing are causing these changes in habitat but we really don't know how often migrations occur normally since we haven't (partially due to technology) been paying much attention.
