Re: Sea waterlevels. former Re: Questions

Quoting Wikepedia for a science subject is merely quoting whatever the great
unwashed wish to believe. Several completely different approaches validate
the so called "hockey stick", see last months Scientific American, a
magazine that is peer reviewed.

Please don't go into that discussion again.
Do you realy think it is worse then Inger's e.g. 154m
sealevel rise during the 200 years Early Bronze Age?

Sea level rise in the Mediterranean (Marseilles) was less than 0.5
m through the bronze age, and in the early bronze age the sea
level was not more than 1.5 m lower than today.

That's a very interesting document. Thank you for finding it.

Very easy, just googling on one of the references for the curve
you expressed "grave" concerns about. Actually the way things are
turning out IMHO, you should now be more skeptical about sources
denying global warming than those who accept it. And just for the
record and having nothing to do with global warming, I would have
preferred the Wikipedia author to have provided references to
papers disagreeing with the smooth sea level rise the late
millenia. You have indicated having them, please post them, thank you.


Where do I start?

First, I don't deny global warming. Quite the reverse. It's happening
now and it has happened before. I would be foolish to deny it. See
http://abob.libs.uga.edu/bobk/ccc/ce032599.html which is from the
Cambridge Conference network for 1999.

Second, I am concerned at the extent to which the science has become
politicised and biased in one direction or another. Perhaps the best
known example is the hockey stick curve which is still frequently
cited even though it's statistics are unsoundly based and it produces
a climate history at variance with the historical record. A reasonably
fair discussion of the situation may be found at
http://en.wikipedia.org/wiki/Temperature_record_of_the_past_1000_years

Third, I am not at all convinced that the present warming is solely
due to the effects of man-made CO2. There is no reason to think that
the natural mechanisms which have caused the climate to change in the
past have suddenly ceased to operate and there is every reason to try
and ascertain the extent to which they are driving the present
increase. The obverse of this argument is that it is very likely that
temperatures would have been rising at this period with or without the
modern industrial age.

The point I was previously trying to make is not that I support one
side or the other in the argument but that the arguments have become
so polarised that it is not safe to take any particular any source at
face value without checking to discover whether or not there are any
contradictory opinions. That certainly is the case when considering
matters related to how much the climate may, or may not, have changed
over the last 2000 years.
