The Largest Living Thing on Earth in Mortal Peril




It's so big it's plainly visible from space. At 2,300 miles in length it's the largest living thing on the planet.

It could be about to die off.

The Australian people have been told they'll have to choose - coral or coal. I suppose it comes down to one letter, "r."

The Great Barrier Reef will not survive a massive coral die-off if ocean temperatures continue to warm.


The Great Barrier Reef will not survive coral bleaching if current sea temperature trends continue, according to a new report charting increases over the past three decades which blames manmade climate change for the problem.

“The likelihood of the reef being able to survive through that is extremely low,” the report’s co-author, Scott Heron of the NOAA, told Guardian Australia. “If annual severe bleaching was happening across 98% of global reefs, it is very unlikely the Great Barrier Reef would be maintained.”

There's This Story Making the Rounds...



It's an item from Reuters that has been picked up by a number of newspapers, including The Globe & Mail.  It concerns a study that found one species of algae has managed to adapt fairly quickly to warming and more acidic oceans.

What's interesting is that the authors of the study went to great lengths to point out the limits of their discovery and to stress that this wasn't some sort of "all clear" on either the warming or acidification of our oceans.  Having noted that, the reporter went on to simply ignore the cautions and proclaim some sort of miracle.

An essential point that's completely overlooked is that, yes algae or phytoplankton do absorb CO2.  Sure they suck it right up like a sponge.  Great, they're carbon-based life forms.  What the writer ignores is what happens to that absorbed CO2.  It's fixed in these organisms and, being organisms, they eventually die and when they die these tiny little organisms sink to the bottom where they decay and release their fixed carbon into the waters of the ocean depths.  They don't make the acidification vanish.  They're simply a conveyor that carries it to the ocean floor.

We know that algae blooms also suck up enormous amounts of dissolved oxygen.  In large concentrations algae can turn water anoxic giving rise to "dead zones".  None of this makes its way into this "feel good" news report either.

However the giveaway that this is a journalistic con job is apparent in the final two paragraphs.  The writer mentions some "U.N. panel of scientists" that is 95% sure that climate change is man made.  That's followed by this closer:

Opinion polls, however, indicate that many voters believe that natural variations are to blame.  The mismatch between scientific and public opinion complicates a plan by almost 200 governments to work out a deal to limit global warming at a summit in late 2015 in Paris. 

There's a journalistic device that pits a powerful scientific consensus based on extensive and ongoing research into every natural science discipline by accomplished and highly-educated experts in those fields against "many voters" whose only qualification appears to be an ability to cast a ballot and then declares a "mismatch".  No, sorry, it's not a mismatch when you pit one powerful consensus based on knowledge, experience and research against a contrary opinion based on nothing.
