Global Warming is turning out to be a hoax, this is the next alarmist
wail to come from the environmental lobby.
Vandeman's idiotic rantings aside, global warming is not a hoax,
although it may be somewhat of a misnomer. I even heard about it
years ago in a graduate-level course on E&M (Electricity and
Magnetism) where a quick estimate of the earth's temperature given the
incident energy from the sun and treating the earth as a blackbody
came out too low (the oceans should have been frozen). The properties
of "greenhouse gases", CO2 specifically, was mentioned as the reason
the estimate was off.
The reason it is a misnomer is that what we are really doing is that
we are introducing gases into the atmosphere that are changing the
transparency of the atmosphere to blackbody radiation at around 300K
but not at the much higher temperature for sunlight (close to 6000 K).
We really do know how this part of it works - we can measure the
properties of these gasses in laboratory experiments, and blackbody
radiation was beaten to death in the early 20th century (understanding
it was very useful in the development of quantum mechanics, so there
was a lot of incentive).
What is far less certain is how the weather and climate will
respond. The models, however, are getting better each year, if only
due to have faster computers with more and more memory. If you hear
someone trying to discredit it by saying A said X and B said Y, check
the dates. The more recent results will be the most accurate (all
else being equal) because each year, we can throw more and more
computing resources at the problem.
Unfortunately, if you take a "we aren't 100 percent sure, so lets
ignore the problem" approach, you should also keep in mind that doing
nothing is basically gambling that nothing bad will happen when all
your eggs are in one basket.
That's odd. That's exactly your approach to cell phones and similar
radiation threats.
What threat? And how does individual decisions regarding cell phone
use put all of our eggs in one basket? There's no plausible physical
mechanism that anyone has proposed to date for why electromagnetic
radiation at 1 or 2 gigahertz might be bad for you, and plenty of
reasons to be skeptical about any claims that it is bad..
By contrast, with global warming, it is fairly easy to calculate what
will happen *if* the climate (amount of cloud cover, etc.) stays the
same - we get a temparature increase dependent on the amount of
"greenhouse gases" we add to the atmoshere. The uncertainty is simply
that we don't know how the climate will change, but we do know that
you'd need a substantial change in cloud cover to mitigate the
temperature rise by any significant extent. Either way, someone is
impacted. The only question is who ends up holding the bag.
So they are not analogous at all.
