– Warnings about ocean acidification are completely misleading – and deliberately so (Ice Age Now, Aug 09, 2014):
“No honest chemist would claim the dissolving of the entire atmospheric mass of CO2 at once would make much difference to the pH of the oceans.”– Rosco Mac
Warnings about ocean acidification are completely misleading – and deliberately so
By Rosco Mac
Firstly, carbon dioxide in water is a very weak acid, whilst the ocean is a very stable buffer with a pH averaging around 8. The concentration of enough CO2 to significantly reduce that pH will not come from the atmosphere – there isn’t enough CO2 in the atmosphere to make much difference.
The mass of the oceans is 268 times the mass of the atmosphere
I can say this with confidence because the mass of the oceans is 268 times the mass of the atmosphere, and CO2 is currently only 0.04% of that.
No honest chemist would claim the dissolving of the entire atmospheric mass of CO2 at once would make much difference to the pH of the oceans.
Secondly, it is well known that an increase in temperature will reduce the solubility of CO2 in water. (The oceans are known as a carbon sink. When they’re cold, they absorb CO2 from the atmosphere. When they warm, they release CO2 into the atmosphere. ed)
Warm up a carbonated drink and see what happens
Warm water naturally contains less CO2 than cold water. Warm up a carbonated drink and see what happens – the CO2 comes out of solution.
The oceans are outgassing CO2 due to the slight warming trend observed. The cause of this trend IS NOT known !
I find alarmists stunningly contradictory and amusing.
They point out the slight increasing trend in temperatures as alarming !
They point out the side effect of this slight increasing trend in temperatures – rising sea levels – as alarming !
Then they claim man’s CO2 emissions will increase ocean acidification as alarming.
But you simply cannot have it both ways – that is an “Inconvenient Truth” !!
Either the oceans are getting warmer and the CO2 concentration in seawater is decreasing – which means that ocean acidification by manmade CO2 from the atmosphere is complete BS !!
– or –
The manmade CO2 from the atmosphere IS dissolving in cooler oceans causing ocean acidification – which means that warming oceans and the associated sea level rises are BS !!
Take your pick – REAL SCIENCE says you can’t have both.
