who are not convinced are by and large not doing sciance in the

transportation. We have a debt we best start paying it now because we
are going to be paying intrest for a long while. so yes starting today
is better than letting the debt get bigger.

How much long-term Data do you need we have almost 500 years of
observed data that can be varified and another thousand in unvarified
observation. and then we have Ice core data back 60.000 years. how
much longer do you want to wait? I have kids and soon will have grand
kids I figure taking care of this now means my grand kids have a
chance.



No problem! There is data going back millions of years. That data
indicates that we are in a typical global warming cycle that is not much
different than the last seven cycles. In fact, its not as rapid as
three of the cycles.

In relation to the CO2 levels in the ice cores, there is a measurement
problem. The CO2 levels taken from the cores are raw levels and do not
allow for any outgasing of CO2 for the thousands of years the ice
existed. Outgasing will reduce the amounts in the ice and will
partially mask the actual amount of atmospheric CO2 at the time of the
ice was formed. (If you leave an open can of sparkling water, the CO2
will eventually escape leaving a can of flat water.)

So if we can't prove that CO2 levels are at a historic high now (which
they aren't anyway) and the temperature rise in consistent with previous
trends, where does that leave global warming?

Global warming is big business. Its not about developing alternative
energy sources. People are making a lot of money doing research and
others are being publicly funded to develop countermeasures to "stop
global warming". So the battle cry is to shout down anyone who
threatens that money source. if that money were spent on developing
alternative energy sources to coal/oil/natgas, we'd all be a lot better off.


The BBC has a special on a few weeks ago where a number of scientists
were interviewed. Though not necessarily addressing the above points,
they presented quite a bit of information that contradicts some of the
theories about global warming. I don't have a link for the video, but
if someone can provide one, it would make for an interesting discussion.


Anyone my age or older certainly can remember the scare of 40 years ago
or so when it was predicted that all the CO2 man was putting into the
atmosphere would thrust the earth into an ice age by 2010. Maybe the
electron spin on carbon atoms reversed itself. Bad electrons!!
