Well, I'm not an expert on glaciers, but I wouldn't be surprised if it were
true. IMHO, the real science behind the global warming debate can
accurately be summarized as follows:
1) The computer models used in pro-warming forecasts are utterly worthless.
We barely know enough about climate change to make rough, short-term
estimates. Detailed predictions about changes decades in the future are
simply not possible - if you try to make a program to do that, all you get
is an automated copy of your own biases.
2) The experimental error in our global temperature measurements is at least
as large as the changes that are being "measured". This means that we
really can't tell if anything is happening or not.
3) Climate changes have so many different effects that it is not at all
clear whether a moderate warming would work out to be good or bad. There
are lots of scary-sounding theories, but we have no idea if any of them are
true or not.
4) Improvements in the data over the last decade have tended to result in
lower estimates for global warming. At this point the changes that most
pro-warming scientists are predicting are smaller than the normal
year-to-year climate variation, which leads me to suspect that the whole
thing isn't worth worrying about.
If we really want to know what is going on here, we'll have to wait until
the climatologists actually know enough to start making predictions
(probably another decade or two given their current rate of progress). Of
course, climate change is such a slow process that it shouldn't be a big
issue to us anyway (that is, if you actually believe that nanotech & AI will
happen in the next few decades).
