Re: uplift???
Kuresu - Uppsala appears to be rebounding at about half a meter per century, according to a map here. I'm guessing, though, that the soil/rock properties have a lot to do with whether a creek is deeply incised like what you seem to be describing - I've seen creeks with mighty steep banks in Oklahoma, which isn't doing much rebounding from either a geological or political perspective.

Re: Birds=Reptiles?
The term "reptiles" includes "lizards, snakes, turtles, crocodiles, and birds,..." but it is a more-or-less obsolete term. Turtles are anapsids, and may not belong with those others, which are all diapsids. And we synapsids are descended from "mammal-like reptiles," which isn't very helpful in deciding if mammals are still reptiles or not.
A situation in flux, from my understanding. Birds are closer kin to crocodiles than to lizards, if that helps at all.

Re: Ocean acidification
There is some dissolved CO2, as CO2, in seawater at the normal pH (around 8.1), and the solubility decreases with increasing temperature. So the acidity will decrease (the pH will rise) with an increase in temperature, if all else is constant.
Pressure enters into this in a big way, as well, as it affects solubility of gasses. So it's only simple in the surface layer where you have the opportunity to establish equilibrium with atmospheric CO2.

Re: Ocean acidification
I don't have a CRC Handbook of the proper age to look that Gibbs Free Energy up - but I'm going to bet that the change in solubility at real ocean temperatures overwhelms any thermodynamic terms anyway.

Re: Ocean acidification
So, you don't even have to have more CO2 dissolved into the ocean to get greater acidity. All it takes is an increase in ocean surface temperatures.
More dissolved CO2 at constant temperature lowers the pH. Higher temperature at constant CO2 content lowers the pH. But solubility of CO2 in water drops by about 50% from 10C to 30C, so I still wonder if a rise in temperature - all alone - might actually raise surface pH.
Of course, when that surface water circulates down to the abyss where it's uniformly cold, the CO2 content will tell the tale. More = lower pH down there at the bottom.

Re: An American Chestnut
Is the pathogen all dead up there in New Hampshire? Moved to Wisconsin, maybe?

A song........
One of you other Old Geezers help me out here.
There was a song on the radio in the late 1960's that my brain will now only return fragments of....perhaps:
"I heard about your quarrels, and how they always end
But I never heard of lovers who could be best friends."
It was one of those hippy freak bands that did country music, but I can't remember who. And Google seems powerless to help me. Can you folks?

Re: A song........
I put that in Google and didn't get doodly-squat.
Of course, this computer HATES me.....
Thanks! And to Percy, too!

Re: Metric System in the Kitchen
Not that many years ago, at least in Arkansas, you could be arrested for possession of a kitchen scale that gave weights in grams. Drug paraphernalia, dontcha know. Somebody could weigh some reefer on it!!!
