Volcanos Hot – CO2 Not

mtetna01Per an article by John O’Sullivan on Suite 101 a new study proves volcanos are hot and CO2 is not!

Global warming and acid oceans have been blamed on greenhouse gases from human fossil fuels. Now growing evidence proves Mother Nature is the most likely cause.

Mother nature?  Not AGW?

A study by Australian geology researcher, Timothy Casey disproves the recent claims by alarmist environmentalists that man-made emissions of carbon dioxide have been causing ocean acidification.

Oops!  What? No acidification?

These disturbing claim has been perplexing geologists, among other researchers, that have failed to detect any increase in acidification in the word’s rivers, lakes, reservoirs and aquariums.

So CO2 is so selective it gets into the world’s oceans, but ignores lakes, streams, rivers, reservoirs, aquariums, not to mention my hot tub? Yeah right!

This study supports what we’re talking about now.

Researchers have looked again at the numbers obtained by oceanographers (i.e. Hillier & Watts (2007)) that surveyed 201,055 submarine volcanoes. From this they concluded an astounding total of 3,477,403 submarine volcanoes must reasonably exist worldwide. They based this finding on the earlier and well-respected observations of Batiza (1982) who found that at least 4 per cent of seamounts are active volcanoes.

As per the usual the IPCC conveniently ignores all these volcanos and cherry picks data to fit their AGW theory…

None of the more than 2,000 active submarine volcanoes have even been discussed in Kerrick (2001), a paper referred to by the IPCC and used to eliminate volcanoes as an important factor in Co2 output into the atmosphere.

Furthermore, Kerrick (2001) justifies the omission of mid oceanic ridge emissions by claiming that mid oceanic ridges discharge less Co2 than is consumed by mid oceanic ridge hydrothermal carbonate systems. There is no evidence to support such a conclusion.

There seems to be increasing volcanic activity, too.

Casey’s study looked at examples such as the Blue Lake in the crater of dormant volcano, Mount Gambier now acidifying due to volcanogenic CO2 input. It lies in the regional centre of the Limestone Coast in the South East of South Australia. It has now been found Mount Gambier is not quite so dormant as some alarmist studies suggested. If this fact was repeated world-wide then it would dispel concerns that human emitted greenhouse gases were the cause of rising levels of sea acidity. The real culprit seems to have been Nature all along.

(I will add that similar is occurring in the Mammoth Mountain area in California  There are areas where gases are seeping out of the ground and killing trees and other vegetation.  More evidence of CO2 venting into the atmosphere).

The conclusion is therefore becoming very clear that atmospheric carbon dioxide can not be the cause of oceanic acidification as we once thought.Thus we may fairly infer it is a non-problem.

In addition to this I have always wondered why they measure CO2 on Mauna Loa because it’s an active volcano.  I wonder how much this inflates the amount of CO2 they claim is in the atmosphere?

Yet another faux pas by the IPCC and their buddies.  The lies just keep on coming.

You Have to Drop a Lot of Acid to Kill Coral

I’ve been reading the alarmist articles about the coral, that will soon be disappearing from an ocean near you, due to ocean-acidification caused from CO2 that’s supposedly caused by AGW.

CO2 Science reports on an experiment about just how much CO2 will it take to create enough acidification to actually kill coral.

What was done
The authors employed controlled infusions of pure CO2 to create mean pH values of 8.03 ± 0.03, 7.64 ± 0.12 and 7.31 ± 0.11 (corresponding to atmospheric CO2 concentrations of 400-475, 905-1660 and 2115-3585 ppm, respectively) in filtered seawater that flowed continuously through three sets of multiple tanks into which they had introduced the gametes of two Acropora coral species (A. digitifera and A. tenuis) they had collected during a natural spawning event, after which (seven days later) they determined their percent survival. Then, after ten more days, they documented the size of the developing polyps; and after 14 days they documented the percentage of polyps that had acquired zooxanthellae that the researchers had collected from the giant clam T. crocea and released into the several treatment tanks.

Wow – sounds like real science!  Not consensus,  magazine articles, or wild-assed guesses.  Here’s what happened.

What was learned
Suwa et al. report that “A. digitifera larval survival rate did not differ significantly among pH treatments,” and the graphs of their data indicate that survivorship in A. tenuis was actually about 18.5% greater in the lowest pH (highest CO2) treatment than in the ambient seawater treatment. At the end of the subsequent ten-day study, however, polypsize was reduced in the lowest pH treatment, but by only about 14%, which is not too bad for an atmospheric CO2concentration in the range of 2115-3585 ppm. And in the A. tenuis coral, this reduction in individual size was more than compensated by the even greater percentage increase in survivorship. In addition, after only four days of being exposed to the zooxanthellae derived from giant clams, all polyps in all treatments had acquired a full complement of the symbiotic zooxanthella.

What it means
In discussing their findings, the seven scientists say they indicate that “the survival of coral larvae may not be strongly affected by pH change,” or “in other words,” as they continue, “coral larvae may be able to tolerate ambient pH decreases of at least 0.7 pH units,” which, in fact, is something that will likely never occur, as it implies atmospheric CO2 concentrations in the range of 2115 to 3585 ppm. In addition, if such high concentrations ever were to occur, they would be a long, long time in coming, giving corals far more than sufficient time to acclimate — and even evolve (Idso and Idso, 2009) — to adequately cope with the slowly developing situation.

CO2 concentrations in the range of 2115 to 3585 ppm.

That’s a lot of CO2!  So quit screaming CO2 is killing the coral  It’s not!
