The lowest hanging fruit as far as lowering CO2 emissions is to get more people cycling. The two biggest obstacles to cycling are lack of bike lanes and flat tires. Most buy a bicycle, ride for a couple of weeks, get a flat, park the bike in the garage and next trip they use the motor vehicle. They never ride the bike again.
The combination of cycling and riding public transportation provides for a lot of options. For example, say you are planning to put your bike on the bus's bike rack and ride the bus to the next town where you'll need the bicycle. You pedal up to the bus stop but before you slow down you discretely glance over to see what kind of characters will be getting on the bus with you. Often you suddenly remember it's been 6 hours since your last aerobic workout. You need more exercise and can save some change by cycling to your destination. This phenomenon happens even after you get on the bus and you spot a big enough crowd at a subsequent stop.
Bob Dole got handicap ramps in all over the U. S. Showers in offices could be mandated as well, at least in humid areas.
Even including accidents cyclists come out ahead. A recent study of Copenhagen commuters showed that riding hard for 30 minutes, the optimum, extended your life by 5 years.
You should be able to ave. 15 mph if you are in any shape at all. Power increases with the square of velocity. If a competitive cyclist can average 25 mph @ 500 watts you should be able to average 15 mph @
As the price of fuel soars, it will become more and more cost effective to live in town.
Row houses weren't built in the early part of the 20th Century because there was no land. They were build because fuel was relatively expensive.
According to an excellent article in _Forbes_ taxes should never be a problem because you can always "taxpatriate" yourself.
"Gas, grass or ass, no one rides for free."
Use a recumbent bicycle which is much more aerodynamic and 5 mph faster for the same effort.
Most do but there is certainly a need for more bike lanes. Visit Tucson, AZ, Davis, CA or Golden, CO for exemplary cycling lane cities.
That's also true for motorists. There is no question a lot of cyclists as well as motorists could use a few tips.
nettiquette is a horrible waste of cola-fired electricity; what was the question?... also, coal-fired.
anyway, the whole thing about bike lanes is silly, since we can ride quite well in the interstices, and California's Vehicle Code applies the same as for automobiles. yes, teh first roadways in teh USA were apparently promoted by a rich bicyclist!
I have ridden around L.A. since the 3rd grade, and I've never had any problem ... but a) use reflectors at night, more than lights,a nd b) wear at least one glove, more than a helmet.
thus: sounds like a good program d'espace for NOAA, but it'd be good to compare heh results of INQUA, as for presumed sea-level changes, qua erosion and "isostasy" and so on.
thus: it was a long while ago, that I last read a journal article that mentioned the state of the art in actually measuring ClO, and it had not been done, then (or, some preliminary measure, I forget), and not even any mention of detection of CFCs (but that could be very hard, if they are mainly to be found on ice-clouds).
not saying that it has had no effect, but that the natural sources are too-easily discounted.
thus: I'm sure that in particular, with the hypothesized/simulated chemistry of CFCs/ClO/ice, that it really is effected by T., although apparently volcanoes can & do produce the first, and possibly the second ... so, Mt. Erebus?
thus: I would love to see a graph of any of the activity of Mt. Erebus, compared with the changes of ozone around the Southern Polar Vortex, or "hole" as you quaintly refer. so, how many "holes in the ozonosphere" are there?
yeah, at least one, except when they break-up, as do the polar ones in the local springtime, when there is virutally no UV to deal with.
now, if you combine the two models of the "holes" in the ozonosphere, with "global" warming, you get a (some what) better GCM.
The biggest obstacle by far to cycling in an urban/suburban are is THEFT.
I would take my bike everywhere if I could leave it parked outside a store or a mall and expect to find it still there when I return. Even a lock will not deter thieves who can cut any lock, cable, or chain very easily with a bolt cutter.
The number one obstacle is THEFT.
The number two obstacle is INCLEMENT WEATHER.
For the cyclist, nothing else matters. Nothing. Nada. Zip.
When you leave it unlocked everyone just thinks it's an abandoned bicycle, you know, like the way people leave stuff they don't want by the road for pickup.
A lock just makes it look like an abandoned bike with a lock on it.
In some places a bicycle will often take on an abandoned appearance if you aren't pedaling fast enough.
In Tucson the time before it's stolen is a statistical combination of factors, how many and what kinds of locks and where it's parked.
2 locks, 1 heavy cable and one shackle, at the down town library: 4 hours during day light hours; 1 shackle lock behind the UA law library: 2.5 hours; 1 medium duty lock in front of the police station: 35 minutes.
The secret is to not park it anywhere very long. After you swim 18 laps at the YMCA on Alameda, go out to the bike rack and move it around the corner. Then go back in and swim 18 more laps.
One student on the 3rd St bike way told me he had a dozen bikes stolen in just 3 years.
In his case you are correct. a Hummer would have been greener.
Not a problem in the desert. Just rig up a lot of water bottle cages.
Quick release wheels really help thieves but they aren't necessary or desirable with the 2 tube system:
