When one reviews all the data, both from thermometers and
paleotemperature proxies, it becomes clear that the Earth has
warmed significantly over the last 140 years; Global Warming is a
reality. Multiple paleoclimatic studies indicate that recent
years, the 1990s, and the 20th century are all the warmest, on a
global basis, of the last 600, and most likely 1200 years. It
appears that the global warming of the last century is
unprecedented in the last 1,200 years.
The peer review does not address man causes for global warming.
Earth has heated and cooled for it whole life. What did man do to
cause the last Ice Age about 15,000 years ago? The mini ice age
500 years ago? And the warming afterwards?
It does not matter what has happened and how it happened in the
past. We are talking about the CURRENT situation. That's why the
right's insistence that it isn't man made is non-think.

Now the past does not matter in global warming and history does not
enter into science. I am not sure I want you engineering a building
for me. You would ignore codes, etc as they are based on history.


Uh, no not really. Codes are based on known strengths, stresses,
strains, etc. And you use the CURRENT code. Using your analogy, you'd
want me to design by a standard that was a few million years old.

If the past does not matter you have no basis to say there is global
warming. Yesterday, last week, last year, last decades' temperatures,
don't exist therefore there are no temperatures to compare today's
temperature, so it can not be increasing

Do this. Show me unmitigated, researchable data that proves for a fact
that global warming isn't occurring.
