My biggest fear is that many are using it to further a political agenda and have no real interest or honesty when it comes to the science or the data.
There are misconceptions because there are so many non-experts muddying the water on the topic.
There are misconceptions because this is being debated with hysterics. Not data.
How in the hell can anyone have a reasonable debate with anyone who starts it with, "We're killing the planet, in 5 years we'll all be dead unless we raise taxes now!" and other hystronics?
I'll continue reading on the topic, I will continue to make up my own mind without either side manipulating me based on a political ideology.
Nothin' but love. . . .

No. . but. . .
Okay.
So someone just let me know when all the data is in.
All I'm asking.
Until then, let's accept the fact that some of us will remain skeptics.
are you skeptical of evolution, then?

Not really.
So you see climate data the same as evolution.
It's a done deal.
Nothing left to learn?

No. My thinking is that the science of it is pretty settled.

Back in the 60s and 70s scientist were blaming earth cooling and possible beginning of another ice age to population and pollution, that eventually would not allow the sun to reach earth, a that time nobody wanted to profit from ice.
Now is different, telling people that they are going to boil alive helps scare them the most, is working.

A Brief History of Ice Ages and Warming
Global warming started long before the "Industrial Revolution" and the invention of the internal combustion engine. Global warming began 18,000 years ago as the earth started warming its way out of the Pleistocene Ice Age-- a time when much of North America, Europe, and Asia lay buried beneath great sheets of glacial ice.
Earth's climate and the biosphere have been in constant flux, dominated by ice ages and glaciers for the past several million years. We are currently enjoying a temporary reprieve from the deep freeze.
Approximately every 100,000 years Earth's climate warms up temporarily. These warm periods, called interglacial periods, appear to last approximately 15,000 to 20,000 years before regressing back to a cold ice age climate. At year 18,000 and counting our current interglacial vacation from the Ice Age is much nearer its end than its beginning.
Global warming during Earth's current interglacial warm period has greatly altered our environment and the distribution and diversity of all life. For example:
Approximately 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 from Asia.
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.
In the 1970s concerned environmentalists like Stephen Schneider of the National Center for Atmospheric Research in Boulder, Colorado feared a return to another ice age due to manmade atmospheric pollution blocking out the sun.
Since about 1940 the global climate did in fact appear to be cooling. Then a funny thing happened-- sometime in the late 1970s temperature declines slowed to a halt and ground-based recording stations during the 1980s and 1990s began reading small but steady increases in near-surface temperatures. Fears of "global cooling" then changed suddenly to "global warming,"-- the cited cause:
manmade atmospheric pollution causing a runaway greenhouse effect.
What does geologic history have to offer in sorting through the confusion?
Quite a bit, actually.
"If 'ice age' is used to refer to long, generally cool, intervals during which glaciers advance and retreat, we are still in one today. Our modern climate represents a very short, warm period between glacial advances." Illinois State Museum
