Hello,
This recent discussion about global warming and the changes necessary
to avoid dire consequences has been very interesting. I am troubled by one
thing, though. As far as I have read (perhaps I missed something), no one has
actually answered the original questions: is there conclusive evidence of
global warming and what percent, if any, is from human sources? Answers have
been given, but as far as I can tell, without any references. Did I miss a
post or two? Does anyone know where I can find the actual data, and perhaps
their interpretation as well?
For example, the web site http://wwwghcc.msfc.nasa.gov/overview/microwave.html displays satellite data
which shows *no* warming trend. The satellite data is supposedly a better
global measure, and not subject to the urban heat island effect as much as the
surface data. What is the response to these findings?
I personally feel that the global warming issue is a real one, but I
also feel that if the scientific community requests that countries radically
change their behaviors, at great expense, then it needs to justify that there
really *is* an effect. I admit that this subject gets very heated, especially
given the stakes involved. Does anyone have a theory (other than urban heat
island) which explains the apparent contradiction between the surface and
satellite data?
