The Pacific Ocean is so acidic that it’s dissolving Dungeness crabs’ shells

The ocean is acidifying because it’s absorbing more carbon dioxide from the atmosphere, which lowers pH levels in the water.

…Ocean acidification changes the coasts, releasing excess nutrient that can create algae blooms and increasing sea temperatures and salinity, according to NOAA.

…For crustaceans and coral that rely on carbonate ions -which are less abundant in more acidic waters- to build their shells and coral skeletons, it becomes more difficult to build strong shells is the pH drops.

…The acidification corroded the young shells of Dungeness crab larvae.

…This could cause developmental delays that could mess with their rate of maturation.

The tiny hair-like structures crabs use to navigate their environments were damaged by the low pH levels, too — something scientists had never seen before. Crabs without these mechanoreceptors could move more slowly and have difficulty swimming and searching for food.

…The acidity wasn’t predicted to damage the crabs this quickly.

“If the crabs are affected already, we really need to make sure we pay much more attention to various components of the food chain before it is too late,” said study lead author Nina Bednarsek, a senior scientist with the Southern California Coastal Water Research Project.

Throwback: Clinton Rallies Her Troops to Fight for Obama

Mr. Clinton remains angrier than people realize about the Obama campaign’s portrayal of his wife as deceitful and of his administration as middling and his political tactics as, at times, racially charged.

…“I want you to ask yourselves: Were you in this campaign just for me?” Mrs. Clinton said. “Or were you in it for that young marine and others like him? Were you in it for that mom struggling with cancer while raising her kids? Were you in it for that boy and his mom surviving on the minimum wage?”

Mr. Clinton became teary at several points during his wife’s speech, and even Mrs. Clinton, who has been so steady this week, seemed to grow misty a couple of times as she thanked her supporters profusely and recalled some of the Americans she met along the trail. Some parts of the speech devoted to Mr. Obama and Mr. McCain, in turn, had a bit of a workmanlike quality, but on the whole her speech echoed with the emotional lyricism that she showed in June when she dropped out of the race and told supporters, “It would break my heart if, in falling short of my goal, I in any way discouraged any of you from pursuing yours.”

…When Kelly Friendly, a Clinton supporter from Wellesley, Mass., was asked if she would vote for Mr. Obama, she said, referring to Mrs. Clinton: “Absolutely. She just told us to, didn’t she?”

Two things….

One: Undermining Democrats who came before but were better than what came before them never serves the party well. Obama’s criticisms of the Clintons (and amplifications of others’ criticisms) came back to bite the party on the ass in 2016.

Two: That’s what supporting the nominee looks like.
