Stop-and-go traffic on freeway + automatic stop engine, same as covering the "idling at intersection". I once had a car that stalled out randomly sometimes - I had to restart it on the freeway once (dropped to neutral and got it running without too much loss of speed). No one needs to be lying.

Comment Re:Black holes are real, we observe them all the t (Score 1) 356

Nope -- no lift necessary. When you add 2*pi*(additional radius desired) to the circumference, it raises it by that amount all the way around the planet.

It's basic math: Circumference is 2*pi*r, so adding delta_r to the radius, you have 2*pi*(r+delta_r), or 2*pi*r + 2*pi*delta_r. 2*pi*r is what was already there, so you only need to add 2*pi*delta_r (in this case, delta_r is 1 poodle of height) to the circumference.

So you're saying we'll run out of all known sources of fossil fuels fairly soon (even assuming a linear instead of geometric or exponential rise, that's ~25 years to reach 550 ppm and completely exhausting all known reserves), and should therefore move to other technologies as soon as possible to ensure a smooth transition. So without regard for whether the climate is changing or not, the results of pursuing policies which have tended to originate from the climate change movement and that would cap (and eventually end) the use of fossil fuels is a good thing.

You also have a lot of fresh water being added to the oceans around Antarctica due to the land ice melting. That brings down the salinity, and reduces the effects of freezing point depression. That sea ice forms at a higher temperature than it used to, so while the temperature is up a little, the freezing point is up more, hence more sea ice even with higher temperatures.

No, but one is a mix of land and sea ice, and one is entirely sea ice. Note here that the one that is increasing is increasing because the Antarctic land ice is melting. That adds a lot of fresh water to the ocean around Antarctica, so it freezes at a higher temperature. Temperature is up a little, but the freezing point is up much higher, so the sea ice is forming more easily. Look up Freezing Point Depression to understand the science behind this.

It is proof of increased temperature if you understand the scientific principles involved. The sea ice extent is increasing because the Antarctic land ice is melting. That adds a lot of fresh water to the ocean around Antarctica, so it freezes at a higher temperature. Temperature is up a little, but the freezing point is up much higher, so the sea ice is forming more easily and further out in the winter. Look up Freezing Point Depression to understand the science behind this.

"North Polar ice cap" is not "Antarctic sea ice". Wrong side of the planet. Note here that the one that is increasing is increasing because the Antarctic land ice is melting.

Peak Demand is typically the middle of the work day (between ~8AM and ~8PM). Running the A/C for all those office buildings, keeping the factory lines running, and so on. For example, for running this factory. That sounds like an ideal time set for Solar usage to me. So your "production is highest when demand is lowest" is obviously false. A few specific climates with harsh winters will seasonally have increased night-time usage, but it's pretty rare.

Also, Geothermal is solid steady production for base load, and Hydro is good for both on-demand and (with pumps) for storage.

"continue legally mandating suburban development and banning urban development,"
Don't be daft.

I don't think they're being daft, just informed. There really are laws preventing good urban development and encouraging suburban sprawl. Heck, AAA used to (and might still - I haven't checked up on it in a few years) lobby for suburban sprawl, and against urban planning, public transit, and other such measures. There's a lot of legislation around making it much harder to build up instead of out.

As a non-lawyer, I'm going off other posts on this topic from other non-lawyers: They'd just file the case in CA to help ensure CA law was used for case. Also, since the one filing the case is likely to be the guy in CA, it'd be a lot easier for them to file locally. Some sort of Long-Arm statute would likely come into play, and the more restrictive set of laws would be enforced.

Likewise, a lot of drivers more or less don't give a damn and will practically run them over, or off the road, or door them.

Or do give a damn and do those things on purpose. Or will throw things at them. I've only had one or two cases in several years of daily commute cycling where I suspect a driver was maliciously trying to edge me off a road, but in some regions its apparently a frequent hazard, and if anyone brings it up, a lot of victim-blaming happens (e.g. cites story of a time they saw a crazy cyclist similar to yours, then claims the person being harassed by a motorist was probably doing something similarly bad, or attempts to charge the guy for inciting the incident in some fashion (see previous link)).

I try to call out cyclists behaving badly, but I find it isn't all that common. When I'm out and about I notice a lot of cyclists behaving perfectly well -- it's just that the odd one or two that don't are the ones that stick out and you notice. The same is true of any vehicle operator -- it's just that people have gotten so used to seeing several dozen traffic violations every day (e.g. failing to signal, running red lights or stop signs, improper turns, failing to leave appropriate space, various parking offenses) without even touching speeding (which would bring it up to likely some 95% of the traffic on the road -- people failing to exceed the speed limit are more likely to be noticed and considered out of place than people speeding). That one cyclist being crazy (and I agree they exist -- I've seen some pretty egregious cycling behavior before) sticks out more since cyclists in general are more rare, but I suspect fewer cyclists in total behave badly with regard to traffic safety (probably because of the inherent additional danger to cycling).
