Climate warmer 81,000 years ago than today
Global warming alarmists won't like this
12 Feb 10 -
New
measurements from coastal caves on the
Spanish island of Mallorca in the Mediterranean show that sea levels were higher 81,000 years ago than today.
The caves were flooded at the time, meaning that the climate must have been warmer than
now.
Oops. Aren't we being told that we're now enduring the warmest
climate
in history? Does this mean that "global warming" might
be a natural
phenomenon?
When the earth warms,
more ice melts and sea levels rise.
When the earth cools, sea levels fall because the water is
locked up on land as ice. In the past, sea levels have stood as much as 130 meters
(426 feet)
lower than today.
The new study, conducted
by geologist Jefffrey Dorale at the University of Iowa in Iowa City,
shows that sea levels suddenly rose to about one meter higher than today.
This finding conflicts with previous models showing
that ice sheets around the world continuously grew and thickened - with
considerable variation along the way - between
125,000 and 20,000 years ago, when they reached a maximum.
“(This study) suggests that, for reasons
unknown, the sea level which at the
time should have been down some 15 meters instead went up one meter,
and then went right back down again within just a couple of thousand
years,” says Columbia University
Lamont-Doherty Earth Observatory geologist and climate scientist Wallace
Broecker.
The finding also implies that ice sheets are
capable of receding considerably over very short periods of time before
resuming their growth at an accelerated pace. But exactly what caused
the 81,000-year-old sea level rise is still a mystery, says the article.
A mystery? Not at all.
If you've read "Not by Fire but by Ice," you know
that this fits in with
my theory that the ice sheets wax and wane in
sync with precession of
the equinoxes. (I have no idea where
Broecker came up with the idea
that sea level should have been down
by 15 meters at the time.)
