Apparently you've never heard of tribes such as the Creeks, Alabamas, Natchez, Chitimachas and Choctaws. They left ruins of their civilizations, many older than the Romans, all over the American southeast. All the Southwest states contain countless ancient remains and Native American sites. In the Texas panhandle you can visit the Alibates Flint Quarries National Monument, which contains some ancient flint excavation pits thought to have been used for up to 12,000 years.

Hmmm... CO2 concentrations in liquid, sure. But what does that have to do with PH? You indicate that it's self-evident, but it's not to me. Maybe you can explain that relationship in high-school sciencey language. There are actually 3 different ways to measure PH, one of which is specific to ocean chemistry (the PH Seawater Scale - sws).

No, it's not, actually. Especially in science (not the scientific community that is awash in politic, but the work of science it certainly is).

Nice try. See above.

I can't understand everything, certainly, but much of it is accessible to me. Much of it because I'm good at maths. And language.

I think you are misreading it. They are using the data from the lake in Japan to demonstrate specific relationships. For 280,000 years. It's no more an extrapolation than "More CO2 increases the greenhouse effect." Physical properties are physical properties.

Most of that is a review of the ONE study on ocean acidification that keeps getting quoted. And those reviews are pretty damning to that study, IMHO.

From ad hominem to straw man, I guess. I never made any such claim - the topic is ocean acidification. I don't even know where you're getting any of this from - unless it's simply an extension of the "attack the messenger" argument that I have already ignored.

More ad hominems to ignore.

You seem to be more familiar with this aspect of the science than I am. I have not looked into those claims although I've skimmed some of the arguments on both sides.

What I found interesting was the critique of the published numbers of PH readings. There are a lot of questions in the detail of what is being measured. Most of all, the most often-quoted studies that extrapolate changes BACKWARD - to the turn of the century - using trends from only 15 - 20 years of data. I haven't seen an explanation for this, but the EPA's website only shows readings from 1980 - 1985. They don't do the backward extrapolation, though.

Google filters those. But peer-reviewed papers are what I look for as an ultimate source. That's the reason I posted the links above. They include many references to the peer-reviewed work.

They are saying it, but is it true. The EPA's website only shows data from about 1985, at the earliest, but PH has been measured fairly accurately since the mid-19th century. And it doesn't match the extrapolated history.

You're right - exaggeration works better. We call it "propaganda". Effective for making Americans afraid of terrorists, too, even though they are 10,000 times more likely to be killed by a hail storm.

No, it turns out the PH scare was false. The original study, it turns out, didn't even use real data - it extrapolated 80 years of PH levels from about 15 years of data. Lots more details.

Not voting for any Democrats, then?

You seem to be another victim of the failing American public education system. While the term "free market" may have been coined after the Constitution, it was a well-known concept to the founders. They were, many, heavily influenced by the writings of John Locke, and while he may not have used that term specifically, his philosophy very much involved what we now call free market principles. Even more so, in fact, because the idea of taxing labour was anathema to him and the founding fathers that he influenced. Property rights and freedom were inseparable.

Yea, he didn't even point out this leftist tendency to come to a conclusion based on a biased viewpoint, without even attempting to review facts.

Well, I can correct you one point (although you may disagree with me anyway). The Una-bomber (a.k.a. Ted Kaczynski) is probably defined most accurately as a luddite more than anything else. If you read his Manifesto, it's clear that he had both extremist left-wing views as well as a right-wing views. If you read how he defines "leftism", I think you will note that very few leftists would agree with his definition. And he calls conservatives "fools". There is certainly nothing in his manifesto that is in sync with right-wing ideology.

Second,

Pretty much. Case in point. In this technique, the individuals under attack are first assumed to be "incredibly racist/sexist/homophobic", and anything flowing from that as an assumed fact sounds reasonable.

This will start happening soon in the US, now that the FCC has passed rules that only protect "lawful" content from getting blocked...

I TOLD you to be careful what you ask for. Everything will be scanned and known. How else will ISPs determine what is "lawful" content and "lawful" protocols (yes, that's in the language, too - "lawful protocols").

Not the only one. I have one that has several non-functional keys because enough of the plastic rivets that hold the metal plate to the internal plastic board have failed, producing a warp. There is probably some technique to re-attach it, but I haven't found one yet. 30 years ain't bad for plastic rivets, but clearly they have a limited lifespan.
