research shows the earth has
undergone a remarkable
cycle of warming and cooling over
the last 400 thousand years.
It warms up fairly quickly over a 10 thousand year time frame,
and then undergoes a slower
period of cooling that lasts for about 100 thousand years.
This cycle has repeated itself 4 times in the last 400 thousand
years. We appear to be approaching the end of the period of
melting of the northern polar ice cap is the main driver of this
cycle. Once it is significantly melted, weather patterns irreversible
change and a new glacial period begins.
has been in an inter-glacial period (warming period) for over
10 thousand years now. Most of the ice shield
over North America and Europe has already melted except for Greenland.
The oceans have already risen an estimated 120 meters and would
rise another 6.5 meters if most of the ice on Greenland
melts (as it did in the last interglacial period).
for visiting our site. Global warming and how we deal with it is
a very important issue to be discussed. Is this happening independent
of what mankind has done to the environment? Will mankind speed
or slow this process? Can we make a difference or is this simply
an overwhelming force of nature that we have to adapt to. Your
participation in this public message board discussion is one way
to bring understanding
to this issue.
