Well, if the scientists say it, then I have to accept it. Although I'll no doubt be ridiculed, I do not have the independent training to argue the findings or the math or the models. (In other words, I have the wrong graduate degree to talk to scientists.)
Everyone says global warming is a fact, especially scientists. People who are skeptical about it are derided as ignorant. So I'm sticking with the scientists on this one. Global warming is a fact, people. We need to do everything the scientists tell us to do in order to save our planet. We need to cut out on emissions that cause greenhouse gases... or whatever.
Which scientists?? There are lots of scientists who are skeptical about global warming as "human caused"--they just don't get much press.
The earth is definitely warmer--but so is Mars. There ain't no "fossil fuel burning" there.
No--the difficulty is telling HOW MUCH of today's warming is human-induced, and how much is "nature-induced".
"This [cooling] trend will reduce agricultural productivity for the rest of the century."
- Peter Gwynne, Newsweek 1976
"This cooling has already killed hundereds of thousands of people. If it continues and no strong action is taken, it will cause world famine, world chaos and world war, and this could all come about before the year 2000."
- Lowell Ponte "The Cooling", 1976
The use of fossil fuels as the cause of it, however, is not. The Anasazi Indians left the American Southwest due to an onset of severe drought. It is safe to assume this was not caused by their use of fossil fuels, SUVs, factories, or power plants. I distinctly recall from the third grade, which was a very long time ago for me, we were taught that we'd just come out of an ice age. We were taught to expect it to get warmer, then after many years the cycle would reverse. I can only assume that these new scientists didn't listen to the teacher during the third grade.
Momma Nature is in charge here.
Surely, you jest?
I'm sure whatever your degree is in taught you that if you begin with a faulty premise, you will likely reach a faulty conclusion.
Your premise that scientists say that global warming is a fact is simply incorrect. Don't believe me? Go to The Oregon Petition and you will see that "scientists" are not only not in agreement over man made global warming, but in fact the vast majority of scientists who specialize in climate sciences consider the idea to be junk science.
Even a step further. Of those those "scientists" who signed on to the UN ICCP report, few had any expertise in climate studies, and a majority represent the biological or social sciences and on the topic of climate change, their opinion is no more valid than yours.
Just little tid bits that you won't hear from the MSM.
Dr. Frederick Seitz Past President, National Academy of Sciences and President Emeritus, Rockefeller University for one has set up a petition project to permit the voices of dissenting scientists to be heard. For an overview of the project visit the website: http://www.oism.org/pproject/s33p41.htm
One of the things about science is that, like the weather and climate, it is always in a state of flux. New theories challenge the old, become accepted, and are in turn replaced with others. Two major reasons to be skeptical of the "global warming" movement in particular are the smugness and intolerance of dissent displayed by its proponents, and the vast amounts of money involved.
