"Global warming" is a real phenomenon: Earth's
temperature is increasing.
You are correct!
"Global Warming" is something that has been
happening for a long time. The temperature of the earth has been increasing
more or less continuously since the time of the cave man.
Approximately 18,000 years
ago the earth began a gradual process of warming up after more than 100,000
years of Ice Ages. Much of North America, Europe, and Asia lay buried beneath
great sheets of glacial ice.
By about 15,000 years ago the earth had warmed sufficiently
to halt the advance of glaciers, and sea levels worldwide began to rise.
By 8,000 years ago the land bridge across the Bering Strait
was drowned, cutting off the migration of men and animals to North America.
Since the end of the Ice Age, Earth's temperature has
risen approximately 16 degrees F and sea levels have risen a total of 300
feet! Forests have returned where once there was only ice.
From a geological perspective, global warming is the normal
state of our accustomed natural world. Technically, we are in an "interglacial
phase," or between ice ages. The question is not really if an
ice age will return, but when.
Don't panic when you hear global alarmists warning the
earth may have warmed almost 1 degree in the last 200 years. Although this
still hasn't yet been proven, it is in fact exactly what should be happening
if everything is normal.
If Global Warming stops, then you can start worrying!
It means our warm interglacial phase is over and we may be heading into
another Ice Age!
