It is only troubling if you give equal weight to all opinions about the science.
We may never do evil that good may come of it. It may be that in suppressing the truth that climate change is a real concern, we might prevent some politician from enacting the harmful measures you mentioned. That is a good thing. But if climate change is a real concern, the means for achieving that good thing was an assault on the Truth. That would be evil. So it all comes back to whether or not it is the Truth. If the cardinal was thinking according to Catholic morality, the Truth is more important than the consequences.
As a non-scientist, but as one who can usually recognize the difference between derivative information and original research, it is impossible to do anything other than recognize that some who claim one side have their facts, figures and graphs while those who claim the other side do as well. Very few people, I suspect, can genuinely recognize what ought to be given more weight and what less. There are also problems with the “spin” aspect of it. As I said, I’m not a scientist, but long ago I was in banking and I know that with the slightest tweak here and there one can make a business look solvent or hopelessly insolvent. Even a bank, and even highly trained regulators are often fooled. It’s like surveying in a way. If you deviate a fraction of an inch at the beginning, you can be miles wrong if you go far enough. And oftentimes it’s difficult to detect that fraction of an inch. Nevertheless, sometimes that deviation is discovered and it throws every conclusion derived from it into a cocked hat.
And we know for absolute certain that this administration has spent enormous sums of money; far more that the “fuel villains” have, on funding MMGW “research”, and has thrown huge sums at political favorites who engage in “alternative energy” technologies. The last figure I saw for the combinaion was $200 billion. That’s a lot of money, and it can gain a lot of agreement.
So why should I give the “pro” side more credence than the “con” side? Because it’s presently fashionable to be “pro”? Because people like DiCaprio tout it but then burn incredible amounts of fuel in a 500 foot yacht? Am I supposed to be a believer when Obama is accompanied by several jets and ships to Africa for his entertainment and has round-the-clock jet fighter protection the whole time, then tells us that our utility bills need to “skyrocket” because of CO2 emissions?
And, of course, I, who spend a great deal of my time outdoors and, due to part of my occupation, have to pay very minute attention to seasons, weather, flora and fauna, water tables and surface flows, and see no difference at all from my childhood except that it’s less hot and dry than it was for a good part of it, am supposed to believe that, well, there really is global warming even though the atmospheric temps are going nowhere because the warmth is hiding somewhere? I’m supposed to give that greater credence than those who say it’s not when my experience confirms the latter rather than the former?
And the last part of the above is a near tautology. You say it’s the cardinal’s job to tell the truth, therefore he had to tell us global warming threatens disaster. But the premise, that MMGW theories are the truth, is assumed. In short, we have to accept an assertion that something’s the truth because it’s assumed to be the truth in the proposition.
It seems, instead, to me that when one sees a contested theory of disaster (and there are all sorts of them; overpopulation, EMP, mutated airborne Ebola, worthlessness of the dollar, on and on) and knows for sure that politicians’ and investors’ strategies for “dealing with it” will cause a great deal of human hardship, but enrich the promoters, it seems to me the truth one sees with one’s own eyes and feels on one’s own skin trumps one that depends on the ginning of computer models that don’t seem to actually be predictive.
Finally, it seems to me that when churchmen adopt one side of a contested and very politicized fact pattern and make pronouncements based on it, and when the political proponents are going to cause human hardship, such churchmen ought to be more wary than they oftentimes are. Again, early on they didn’t foresee forcing the Little Sisters of the Poor to pay for abortifacients either when they went all giddy over “universal healthcare”. One would think “once bitten, twice shy”.
