Senate Approves Trimmed-Back Energy Bill
Global Warming on FreeRepublic

Adding dry ice to the water is a quick way to add more carbonic acid to the system. But the flask should be sealed to increase CO2 in the headspace, so more dissolves in the water over time.
“Coral Reefs under Rapid Climate Change and Ocean Acidification, co-authored by seventeen marine scientists from seven different countries, reveals that most coral reefs will not survive the drastic increases in global temperatures and atmospheric CO2 unless governments act immediately to combat current trends.”
Such crap. Coral reefs have survied way warmer environments then we presently have and that these clowns are forecasting.
Finally, a compelling reason to keep the entire Third World poor and miserable, from lack of access to fossil fuels, until WE get it “right.”

Adding dry ice just increases the CO2 pressure to 14.7 and an equilibrium conc. will be reached. If the flask is sealed it will most likely explode. Any drift seen on the pH meter is drift in the glass and reference electrodes.
Evolution in action. Atmospheric CO2 concentration is not going down this century, it is only going up. If this will kill coral then goodbye coral. These guys are telling horror stories about bad things happening over which we have minimal control.
Pure Eco-Porn...

Have you ever had a taste of soda water? If so, why is it "tart"?
If you put dry ice in an open glass, let it melt (actually sublimate), then taste the water, you'd discover that the water tastes tart -- because of the carbonic acid that dissolves in the water from the dry ice. The pH has to change when this happens. Seawater pH will change less, because of the buffer system. But it will change.
Hunble, this brings up a safety factor. I'd suggest doing this experiment in a plastic soda bottle. Add the dry ice in little pieces, then put a balloon around the neck of the bottle and affix it tightly with a rubber band. The ballon will inflate some, but this will keep the headspace charged with CO2 while greatly reducing the explosion risk.
Coral still has a chance if the maximum CO2 concentration in the atmosphere can be limited. It's another reason for energy efficiency and reduction of CO2 emissions.
I would argue that the American central section needs to be saved from ‘climate change’.
And if that doesn’t get people willing to comply and give up their freedoms, what will they choose next?
We’re actually well below the average temp of the earth for most of its geologic history. As it stands now, any warming is just the earth returning to its naturally warmer state. Why would we want to interfere and keep it cooler than average?
Give me global warming..... please.....
They say that we can keep global temperatures from rising 2C by cutting CO2 emissions by 25% to 80% (depending on which shaman you listen to) over 1990 levels by 2050. Do you really believe that this is even remotely possible given most of the world is over 1990 levels and the developing world is 2-3 times their 1990 levels.
Soda water is a supersaturated solution of CO2 in water. It's pH is 5 something, as is distilled water that's been exposed to the atmosphere. Once the cap's off the soda water it will release CO2 until the equilibrium conc. corresponding to the atmospheric conc. is reached.
"Seawater pH will change less, because of the buffer system. But it will change."
Seawater pH is 8.1+/-0.1, that's good enough. Calling a change within that range acidification for the purposes of justifying "serious problems" for coral is flat out BS. That's the findings of the research, which is mentioned in that paper above, which fails to include mention of the complete local system in fig2.
Once all the components of the system are included, there is no net change in CO32-, because the increase in CO2 causes an increase in dissolution. As I pointed out, the same increase in dissolution occurs locally when alkaline carbonates precipitate to form the corals. IOWs pH does not depend on alkalinity in the real system, it depends on the saturation conc of the alkaline earth components Ca and Mg and all the various dissociation constants.
Who said they did?
My point was simply that this lesson was typical of what our 6 year olds receive as their global climate change primer in schools today.
Wiki has this to say;
“Compositional differences from fresh water
Seawater is more enriched in dissolved ions of all types than fresh water. However, the ratios of various solutes differ dramatically. For instance, although seawater is ~2.8 times more enriched with bicarbonate than river water based on molarity, the percentage of bicarbonate in seawater as a ratio of all dissolved ions is far lower than in river water; bicarbonate ions constitute 48% of river water solutes, but only 0.41% of all seawater ions. Differences like these are due to the varying residence times of seawater solutes; sodium and chlorine have very long residence times, while calcium (vital for carbonate formation) tends to precipitate out much more quickly.”
Not that that enters into your tautology, yet I often wonder if you are after definition or simply attribution.
Boy, if that don’t make you humble, I can’t imagine what would. :>)
Seriously, those were the most enjoyable times of my early adventures in bacon-bringing; still miss being surrounded by people smarter than me.
“Global warming” hoax BUMP.
Pass the salt,please....thank you
