Ho Hum! The ocean "acidification" scare again

The Warmist claim below  -- from an alleged "Science" magazine -- that CO2 Pollution could erase Coral Reefs ignores the Warmists' own  theory that CO2 causes warming!   A warmer ocean would hold LESS CO2 and there would therefore be LESS "acidification"!  Basic physics indeed.  You can demonstrate it in a school science lab using nothing more than two cans of Coke, one warm and one cold.

It's hard to get more more dishonest or impervious to facts  than these ocean acidifiers but for what it is worth, there are some additional facts on their nonsense following the excerpt below

Coral reefs, nature’s most lively architecture, could come tumbling down and it could take millions of years for them to return, if carbon dioxide emissions aren’t cut quickly, scientists warned today.

The world’s oceans have absorbed 40 percent of the carbon dioxide emissions produced by humans in the industrial age, but that buffering is changing the chemistry of the oceans. Already, the acidity of ocean waters, which are generally basic, has shifted about 0.1 on the pH scale, or 10 percent, since pre-industrial times, and could get far more acidic by mid-century.

In a editorial in the journal Science, the researchers also noted that unlike CO2′s climate impacts, which vary between models to some extent, ocean acidification is based on basic chemistry and is nearly sure to occur if we continue burning fossil fuels, with disastrous consequences for some marine life.

"What we’re doing in the next decade could mean that for the next two million years, there are no coral reefs in the ocean," said Ken Caldeira, a Stanford professor, and recent Wired profilee.

While most of the attention on the impacts of carbon dioxide emissions has focused on its ability to act as a greenhouse gas, that warms the earth’s climate, the changes CO2 emissions will bring to the world’s oceans are receiving increasing attention. The more CO2 in the atmosphere, the more of it that dissolves into surface ocean water. That small chemistry change could cause huge changes in marine biology.

Marine organisms, like coral, that build skeletons out of calcium could find themselves unable to do so. If current emissions trends continue over the next decade, the world’s marine creatures will be dealing with what’s essentially an alien ocean. The last time ocean conditions like those predicted for mid-century existed was long before humans walked the earth.


Coral reef history

Corals evolved during the Cambrian Era, when CO2 levels were eight to twenty times higher than today. The great coral reefs of the Permian era formed when CO2 was as high as 3,000 ppm CO2.

Obviously corals like high levels of CO2.
