Dr. Guy has a recent entry where he claims there is a debate, yes a debate, about global warming. You can deny global warming if you like, but denial does not make a debate. To debate you should do more than just point to extreme behavior from the opposing viewpoint--you should also provide some justification for your own. This is difficult to do, because climate change denial is at its heart nothing but a statement of opinion that there isn't enough proof. It is an argument of negatives.
Negative Space
Global warming deniers have no evidence to support their ill formed opinion. Having little to defend themselves they attempt to draw attention to the unknown and irrelevant. Pointing out that not everything is known yet about climate change is not an argument that global warming does not exist.
Not everything is known about gravity, there are many holes and inconsistencies in grand theory. But that doesn't mean things don't fall. Electricity is both highly understood, and still vastly mysterious, but you can't deny that science and the scientific method have allowed you to be at a computer reading this.
When we want to know about things like global warming or climate change, we ask scientists. And they tell us what they know and what they don't know. The fact that they don't know something, is, again, not a direct refutation of what they do know.
So what does science say?
If any debate exists , as is Dr. Guy's main claim in my opinion, it is not among the people I would trust to know. Scientists, people who devote their lives to specifically and methodically studying the world, say global warming is real. Dr. Guy says, "there is no conclusive answer yet", but provides no evidence of that. On the contrary, all evidence points to scientists being in near agreement on the base ideas of increasing average temperature and a real human influence on that.
Even the Wiki pages discussing the "Scientific opinion on climate change" and the "Global warming controversy" are not marked as controversial, disputed, or biased in any way. The facts are in and global warming is real.
There may exist individuals who will dispute this, but no repeatable, methodologically sound experiments exist to provide any factual evidence for global warming deniers. You can find someone to say anything, as Dr. Guy demonstrates with his unsourced environmental group asking for climate change denial to be illegal, but the overwhelming scientific evidence supports the consensus among the scientific community--global warming is a real phenomena.
The evidence supporting the broad topic of global warming is based on contributions from fields such as geology, climatology, biology, archeology, and many more. The few "scientists" who deny global warming tend to come from perhaps the one field least likely to have a valid opinion on the matter, "political science". Most global warming deniers have no credentials whatsoever, and even irrelevant economic and political arguments are soundly debunked. The jury is not still out, scientific facts, empirical data(PDF), and the agreement of experts in relevant scientific fields confirm the reality of global warming.
WWJD?
There really is no serious debate among the scientific community, as my sources have shown. There does exist some debate among theologians, specifically Christians. But even among many evangelicals, the debate centers not around the reality of climate change, but around how God's word in the Bible tells us to deal with it. Does the concept of "stewardship" mean Christians should strive to protect God's gift, or do Biblical imperatives for helping the poor trump such arguments? While this may be a debate, it remains a debate of theology at best and political policy at worst. It is a debate of the response to more so than a debate about the reality of climate change.
There are many Christian deniers, of course, but they almost always resort to the negative argument and are in no position of scientific expertise to speak on scientific matters. If believers want to believe because they feel some Biblical justification, then they can debate the Biblical justification. Until they provide scientific evidence in support of their opinion, it has no bearing on the actual state of the world, and should not affect public policy.
Truth and Consequences
Pascal's Wager is not a purely logically sound argument, because in it's strict application it could apply to any fanciful notion. But, in light of the scientific proof and the theological near admission, climate change becomes an apt subject for an exploration of Pascal's base argument. Applied to global warming, Pascal's Wager might be phrased:
Considering the authority of experts--secular and sectarian--argument, the experimental supporting data, and moral motivations for accepting global warming, we are faced with an option.
Deny that it exists, do nothing, run out of oil, drive plants and animal species to extinction, and possibly ruin things so spectacularly as to wipe out humanity altogether in a horrific manner.
Or, accept that it is reality, and make efforts to protect the environment and prevent further damage in concert with a strategy to improve the standard of living for everyone economically and spiritually.
Unlike the existence of an afterlife, the fact that we are going to have kids is well established. How should we behave in this life to best deserve, receive, and achieve the spiritual reward of a better life for our descendants?
What is the point?
Dr. Guy points to an extremist view held by passionate environmentalists. First, extremists views are just that; non-reflective in many cases of the mainstream. Not only besides the point he seems to be trying to make, it also ignores the larger context in which this statement was made. Think what you may about France and Germany, but they have laws against lying and are not communist. The United States has laws against lying, such as against slander, libel, and perjury. Denial law is a current global ongoing debate, and this is an attempt to ride the bandwagon. I'm sure they appreciate the free publicity Dr. Guy has given them.
I tend to agree with Dr. Guy that freedom of speech is more important than making lying illegal, but I find it disingenuous for a supporter of Bush's Patriot Act and, presumably, the Military Commissions Act, to cry about infringement of civil liberties.
Climate change denial is simply factually incorrect, theologically nearly indefensible, philosophically unwise, morally irresponsible, and ethically neglectful .
If a debate about global warming really does exist, as Dr. Guy claims, it is a debate the deniers have lost.
