Indeed. Things especially appear complex before good physical laws
are formulated that explain and predict properly. Then the mystery
and complexity gives way to straight-forward calculations.
This issue of global warming is interesting and is a charged topic to
be sure. A few observations:
1) some measurements used to indicate warming are spurious. A PBS
show showed a data collection point used in Phoenix, Arizona. The
data for the past many years show much higher temperatures than in
previous years. Then somebody went to find the data collection
point, which is now located in the middle of airport tarmac! Early
years, no tarmac surrounding it. That asphalt is worth at least 10
or 20 degrees... so there is some bad science going on.
2) With so much written supporting global warming, I looked for any
writing against it. There is an interesting book published in 2001
by Cambridge University Press: "The Skeptical Environmentalist", by
Bjorn Lomborg with a lot of statistics and data that give a bit more
balance to the issue. Recommended reading.
3) Frank's back of the envelope work about sea level rise and volume
are what we need more of. Nice work Frank!
4) One good volcano eruption can really change the atmosphere far
more than what man can do in many years time. Many volcanos can do
more.
5) I agree that we should make more efficient cars (I have two
diesels that get much better mileage), and that we should do more
with solar and wind power to avoid our reliance on oil.
6) I like sextants. (This is my nod to traditional navigation.
Thanks to Marc B. for the idea!)
