This sort of thing is pretty easy for most people. Very very few adults adopt beliefs or positions from critical thinking or by weighing evidence. Virtually all of us come to our beliefs by adopting the beliefs of someone they admire (parents, a spouse, a TV idol, a professor, etc.). Then, for the rest of their lives, they just filter out any facts that don't align with their adopted beliefs.
Allow me to be the monkey wrench as I actually do have a degree in Ecology. No one respects Patrick Moore; that is, anyone in the scientific community. He's flip flopped more times than Ben Carson and has quite literally become the antithesis of what he originally set out against. There isn't even a debate about what he's saying, It's political nonsense. For every 100,000 people saying the sky is blue, there will always be one who says it's red and swears they have good evidence on why everyone else is wrong. It is always wise to lend an ear and see what they have to say, but if you can filter it out pretty quickly, it's best not to waste too much time listening and that is the case with Dr. Moore. He makes more in just endorsements than most of us do in 5 years at our jobs.
