For those of you on coral-list who are interested in the discussion of Ocean Acidification and whether it is affecting reefs and whether it will have major effects on reefs in the future or not, there is a new post on coralreef-freeforall that you will find interesting, I predict.  Check it out.    Cheers, Doug

In 2010, a survey of more than 1,000 of the world's most cited and published climate scientists found that 97 percent believe climate change is happening and primarily caused by humans.  Anderegg, W.R.L. et al 2010.  Proc.. Natl. Acad. Sci. USA 107: 12107.

The technical word is appropriate but those opposed will identify that the word acid is loaded like the word kill but both (A&K) may be correct
Remember the impact of "Acid Rain" or was it "Purple Rain", and remember long ago "Acid" (=LSD) 
 
I watch the "Global Warming" vs "climate change" which has the same loadings Acidification vs Reducing pH and Killing vs Adversely Affecting
I also watch the "Fracking" vs "Unconventional Gas and Oil"
 
Use acidification it is Correct but also Loaded, and explain as needed lower pH

  I have been using 'acidification' in this context for decades in association
  with the titration of seawater samples with HCl to measure alkalinity. I add
  HCl to the water and the pH goes down, and if I add enough acid the pH falls
  below 7.0 (I titrate to pH 4.0; I would also note here that the neutral pH
  of pure water varies inversely with temperature, being 7.0 only at 25 C). I
  suspect I adopted this use from a chemistry book, or methods paper, or from
  talking with a chemist. I never encountered any opposition to my use of
  acidification until 'ocean acidification' came along and skeptics started
  arguing that it is an incorrect and misleading use of 'acidification,'
  apparently in an attempt to deny that ocean surface pH (and alkalinity) is
  decreasing measurably.
