Let me add some "logic" to this thread......if I may
SO WHAT if sea levels have been rising? This STILL does not prove it is from any kind of "Global warming".
It could be caused by tectonic plates moving.....or subterranean displacement of land mass by deep geothermal processes such as magma movement etc
The Earth's temperature is also affected by solar radiation. Also, orbital variations.
MAYBE...."some" of it could be due to a warming Earth, but even that has not been proven to be caused my man. Rather, evidence clearly shows that warming and cooling trends are part of NATURE.....and are cyclical.
So just because Nasa or Al Gore confirms rising seal levels, that is in no way conclusive evidence of "man induced global warming".
In fact, there are also studies from NOAA and NASA that indicate we may be headed for a long term cooling period.
