Wait, do those help you grow hair?

It happened from the 1930s to 1970s. No reason it can't happen again.

I was merely pointing out that there were HVDC lines coming in from the north which you didn't appear to know about.

As far as coal power in California I believe that all of the states utilities have been mandated to eliminate any coal power from their portfolios and although that is not complete yet they are well on their way to the goal.

And for the CONUS as a whole the amount of coal power has been dropping, largely as a result of increasing natural gas generation and I think in 20 or 30 years coal will be a miniscule piece of the nations energy supply.

Any serious gun nut is going to have the equipment and supplies to do their own hand loading and can keep going until their supplies run out.

Personally I prefer light-fortnights.

Pluto's orbit is the most eccentric of any planet (or former planet :). Its distance from the Sun varies from about 30 AU to 49 AU. Any planet with that kind of eccentricity would have considerable climate change as it traveled along it's orbit.

I'm not the AC but there are some HVDC lines that go through Central Oregon to California. It's called the Pacific DC Intertie.

I replaced a toilet about 3 years ago that was plugging at least once a week with one recommended in Consumer Reports. It cost me about $260 plus installation. The new toilet uses 1.28 gallons/full flush and 0.8 gallons for a partial flush. I've had it for 2.5 years now and it's only plugged once in all that time. And I never have to flush it more than once (except the time it plugged where I let it sit for an hour or so and flushed it again which cleared the plug). So, if you get a quality low flow toilet it works just fine, if you go cheap expect problems.

I completely disagree with this. It's like the old adage "Give a man a fish and you feed him for a day; teach a man to fish and you feed him for a lifetime." Same thing with learning --- unless you think the only place that learning takes place is in school.

Sorry for the messed up formatting. That should have read:

This is an important point. Standardized tests assume everyone is like a cog coming off an assembly line. Good education should be tailored to needs of the student, not the needs of an industrial education system.

We know there were Polynesians on Easter Island which is closer to South America than it is to Australia. Maybe some of them made it to South America long ago.

That's close to but not exactly true. Biological processes such as photosynthesis tend to prefer the lighter C12 isotope over the heavier C13 and C14 isotopes so the ratio of C12 to C13 & C14 is higher in plants than it is in the atmosphere.

Breathing is not the way humans (and other animals) take up carbon. It comes from the food we eat. So burning coal to heat your home doesn't have any direct effect on your personal C14 level.

I only care about people who disagree with science when they interfere with us facing the reality that science tells us about.
