Well, abortion is murder, plain and simple; we all know this. Climate change, OTOH, is a theory, one which is not definitively proven by any scientific means, despite the vociferous and often fanatical declarations of the media and some sectors of the scientific community. Many of the latest trends (which have gotten very little media coverage, of course) indicate that we're actually entering the leading edge of a cooling trend; and in fact, there hasn't been any radical "warming" for a decade now---it's been static.
But, if the good bishop believes that climate change is a danger, good for him. For myself, I recall that 1500 years ago, the Vikings were growing wheat in southern Greenland, and there certainly weren't any man-made "greenhouse gases" causing it back then. You can't, by the way, grow wheat in Greenland at the current time, no matter how warm it might be.
So I tend to be of the opinion that "global warming", if it's happening at all---and that's a big "if", is not caused by human activity, but rather by natural cycles; and even if it
is happening, there's not a great heckuva lot we can do about it. But I am not worried. This is still God's world, and He's still in charge of it, not me and not you. He will do as He sees best, and that's fine with me. Our primary concern should be getting to the
next world anyway, not what happens in this one.
When the first new crop of Greenland wheat comes in, let me know....I'll be concerned at that point.
