Comments like this is the basis for why the 'debate' about climate change becomes so corrupted.  It's actually good for the economy when government tightens up on emissions and mandates increased fuel efficiency because it spurs on innovation and accordingly creates jobs and new industries.  What's the downside...It goes against your best interest if you've invested in Shell, Chevron, Exxon Mobile, Oil ETFs, Master Limited Partnerships, etc.?

I'm not sure why I'm bothering, but for me it comes down to a desire not to be manipulated by fear as well as the desire not to be demonized for it.  According to Wikipedia, we have had a temperature increase since about 1900 of 0.74 +- 0.18C.  CO2 levels back then were about 280ppm, we're currently at about 400ppm.  Calculate that out, and it would appear that we should expect an increase of around 1.7C for a doubling of CO2.  OK, great.  I'll keep that in mind over the next 80 years or so.  Not nearly as high as what they are trying to scare us with.  I keep an eye on sea level data at http://sealevel.colorado.edu.  That first graph has been pegged at 3.2 +- 0.4 mm/yr for the last couple or more years now.  Not even a hint that it will start erupting upward anytime soon.  We're talking a little over a foot a century.  Nothing to piss our pants about.  Sea ice in the arctic continues to frustrate those who keep expecting an ice free summer.  No idea what it will do this year.

Almost everything else is speculation and over-exaggeration as far as I can tell.  I don't buy into the "man is killing the planet" morality play.  I don't see any need to put any brakes on the economy in order to force us off of oil.  If anything, we need the economy as strong as possible so we can be effective when we need to be.  I don't think we should be messing with geoengineering schemes quite yet.

If things take a sudden turn for the worse, I'll rethink my position.

That's my basic take on it.  I'm not interested in yet another back-and-forth exchange.


P.S.  As for the possibility of religion trumping my common sense on this topic, I have no idea what spiritists / occultists think about climate change; as far as I can tell there is no position on it.  Maybe all 12 of us should sit down and discuss it sometime.

Perhaps I misunderstood, or you were engaging in hyperbole for amusement...
You can't really mean to suggest that everyone who has a view on anthropogenic global warming is merely "clinging tightly to their own blind biases."
Or just the people you "hang with?"

Thus Deb makes a good point about some who "melt-down," who are denying the validity of the thousands of peer reviewed scientific studies indicating significant anthropogenic climate change is occurring, when confronted with this body of science.
But as I recently told a local climate change activist, if you want to find peer reviewed published scientific studies that question the consensus scientific view on anthropogenic climate change, they can be found.  I have made a deliberate effort to study the scientific theories that indicate anthropogenic climate change is not a problem to the extent most competent scientists indicate it is...
Below are a few that have generated considerable discussion in recent years.  I'll not present the scientific refutations of these published scientific papers, but refuted they were.
Note the first paper below is authored by the famous Richard Lindzen from MIT, who former NASA climate scientist James Hansen described as "the dean of anthropogenic climate change skeptics" in Hansen's book "Storms of My Grandchildren:"

Claiming a "misdiagnosis" indicates the "skeptical" analysis here...-----------------------Regarding your statement "The sad reality is that throughout history science has been routinely trumped by politics and religion until it can be proven beyond all doubt." demonstrates a misunderstanding, according to my study of epistemology, theory of knowledge, and the scientific method, of the nature of scientific inquiry.  Nothing can be "proven beyond all doubt" technically speaking.  New data or theory can always alter a given scientific consensus, though some scientists would argue this is philosophical nit-picking on some very well established theories.
But consider the millions of people who insist that the theory or evolution, insofar as it indicates homo sapiens evolved over millions of years from other species, is not a "proven" scientific theory, despite the overwhelming scientific evidence.  Science is still "trumped" by religion on this issue.
Given the bias of some people, it does not matter how well "proven" a scientific theory may be... it will still be denied!---------------------------------------Vision2020 Post: Ted Moffett

They just reject any report and / or attack the source that doesn't align with their own unalterable belief.  The sad reality is that throughout history science has been routinely trumped by politics and religion until it can be proven beyond all doubt.  And personally, I'm OK with that to some extent because the effect is that it forces very comprehensive and far reaching studies to unearth all the facts and impeach all of the fiction.

This short video is a good parallel of what happens whenever the topic of climate change comes up with either my 'global warming is a myth' friends or with my 'we are going to die because of global warming' friends:

Thanks, Ted. this is good info, and assists me when 
i talk to folks with little science background and a denier agenda---you are 
always on top of it!  I have watched climate denier folks melt-down when 
confronted with facts that refute their disbelief---even they can only suspend 
disbelief until their arms hurt a bunch....and most of them don't have the 
muscle mass....

  4-13-15: Ruddiman's Early Anthropogenic Climate Impact Theory

  I was surprised to just today read on Realclimate.org a piece dated 13 
  April 2015, by climate scientist William Ruddiman, discussing how the 
  scientific community has received his controversial theory regarding early 
  (before major fossil fuel powered industrial civilization) human climate 

  His Realclimate.org piece argues, and I quote, against the 
  alleged "censure from a nearly monolithic community intent on imposing a 
  mainstream view" that is sometimes claimed to exist by those critical of the 
  science demonstrating major human impacts on climate change. 

  I was particularly interested in this Realclimate.org piece because I 
  referenced his theory in a 2007 op-ed in the Moscow-Pullman Daily News, which 
  now has a Google News webpage of an actual scan of the actual op-ed page in 
  the Moscow-Pullman DN.  How or why this scan happened I do not know, but 
  it can be read at the webpage below:


  Ruddiman's Realclimate.org article mentioned above is pasted in below, 
  and comments generated by his article are also available at the website 


  A Scientific Debate Filed under: Climate Science — mike @ 13 April 

  Bill Ruddiman, University of Virginia

  Recently I’ve read claims that some scientists are opposed to AGW but 
  won’t speak out because they fear censure from a nearly monolithic community 
  intent on imposing a mainstream view. Yet my last 10 years of personal 
  experience refute this claim. This story began late in 2003 when I introduced 
  a new idea (the ‘early anthropogenic hypothesis’) that went completely against 
  a prevailing climatic paradigm of the time. I claimed that detectable human 
  influences on Earth’s surface and its climate began thousands of years ago 
  because of agriculture. Here I describe how this radically different idea was 
  received by the mainstream scientific community. 

  Was my initial attempt to present this new idea suppressed? No. I 
  submitted a paper to Climatic Change, then edited by Steve Schneider, a 
  well-known climate scientist and AGW spokesman. From what I could tell, Steve 
  was agnostic about my idea but published it because he found it an interesting 
  challenge to the conventional wisdom. I also gave the Emiliani lecture at the 
  2003 December American Geophysical Union (AGU) conference to some 800 people. 
  I feel certain that very few of those scientists came to my talk believing 
  what my abstract claimed. They attended because they were interested in a 
  really new idea from someone with a decent career reputation. The talk was 
  covered by many prominent media sources, including the New York Times and The 
  Economist. This experience told me that provocative new ideas draw interest 
  because they are provocative and new, provided that they pass the key ‘sniff 
  test’ by presenting evidence in support of their claims. 

  Did this radical new idea have difficulty receiving research funding? No. 
  Proposals submitted to the highly competitive National Science Foundation 
  (NSF) with John Kutzbach and Steve Vavrus have been fully funded since 2004 by 
  3-year grants. Even though the hypothesis of early anthropogenic effects on 
  climate has been controversial (and still is for some), we crafted proposals 
  that were carefully written, tightly reasoned, and focused on testing the new 
  idea. As a result, we succeeded against negative funding odds of 4-1 or 5-1. 
  One program manager told me he planned to put our grant on a short list of 
  ‘transformational’ proposals/grants that NSF had requested. That didn’t mean 
  he accepted our hypothesis. It meant that he felt that our hypothesis had the 
  potential to transform that particular field of paleoclimatic research, if 
  proven correct. 

  Were we able to get papers published? Yes. As any scientist will tell 
  you, this process is rarely easy. Even reviewers who basically support what 
  you have to say will rarely hand out ‘easy-pass’ reviews. They add their own 
  perspective, and they often point out useful improvements. A few reviews of 
  the 30-some papers we have published during the last 11 years have come back 
  with extremely negative reviews, seemingly from scientists who seem deeply 
  opposed to anything that even hints at large early anthropogenic effects. 
  While these uber-critical reviews are discouraging, I have learned to put them 
  aside for a few days, give my spirits time to rebound, and then address the 
  criticisms that are fair (that is, evidence-based), explain to the journal 
  editor why other criticisms are unfair, and submit a revised (and inevitably 
  improved) paper. Eventually, our views have always gotten published, although 
  sometimes only after considerable effort. 

  The decade-long argument over large early anthropogenic effects 
  continues, although recent syntheses of archeological and paleoecological data 
  have been increasingly supportive. In any case, I continue to trust the 
  scientific process to sort this debate out. I suggest that my experience is a 
  good index of the way the system actually operates when new and controversial 
  ideas emerge. I see no evidence that the system is muffling good new ideas.
