Oceans Ten Times More Acidic Than Thought

http://www.morguefile.com/archive/?display=98154
National Geographic has a curious article entitled, Oceans Ten Times More Acidic Than Thought" that contains so many errors it's difficult to know where to begin. For starters, the title implies that the ocean is ten times more acidic that previously thought, like it slipped from 6.5 to 5.5pH, catching researchers off guard. In reality, it's the increase in acidity that is ten times higher than some climate model predicted. Perhaps a better title would have been, "Global Warming Model Incorrect By an Order of Magnitude".

The word "Oceans" in the title implies many of our oceans have increased acidity, but the article cleanly states the research applies to the ocean around one island (or perhaps "Oceans" in the title needs a possessive apostrophe).

A whale of a contradiction in the article is "...carbon dioxide dissolves in the oceans it forms carbonic acid, which in turn has a negative impact on marine life.", but later the article claims, "Larger mussels and barnacles suffered, leaving smaller barnacles and some calcium-based seaweeds better off."
Increased acidity doesn't have a negative impact on all marine life. Under almost any change in environment, some species will do better and other will flounder.

The article ends with a stinging quote: "This is typical of so many climate studies—almost without exception things are turning out to be worse than we originally thought." This clearly is a call to the readers to do something about the tsunami of impending climate change. Although it could be argued from the article that there's something fishy with these climate models which can't make accurate predictions.

The whole article should be taken with a grain of salt.

Arctic Ice Nonsense

iceburg

Argghhh. Are journalists just getting stupid?
From the Oct 1, 2007 issue in Time magazine on page 30:
"This summer, however, saw something new: for the first time in recorded history, the Northwest Passage was ice-free all the way from the Pacific to the Atlantic."

OK, we are all to believe that global warming is real based on this fact.
Later in the magazine they clinch the environmental danger from the opening of the passage with this:

"The idea of Liberian-registered tankers chugging through the Northwest Passage or oil spills that can't be cleaned up--that's what terrifies me," says Mike Beedell, an Arctic adventurer who sailed a small sailboat through the passage 20 years ago.

Wait a minute. This summer is the first time the passage is open, and they are quoting a guy in the same article who sailed the passage 20 years ago?

I can understand the reporter not researching their own Time magazine archives and missing an article from 1944 describing Henry Asbjorn Larsen's trip through the Northwest passage. (which by the way mentions a previous trip through the passage by Roald Amundsen). But to miss something later on in the current article?

So we are to believe this is the first time in history the passage is open when the magazine itself mentions three previous maritime voyages through the Northwest passage?
Do the editors of Time think the excessive heat from global warming is addling our brains and we won't notice? What do you think?
