To buy into the current narrative about global warming, you have to believe 3 things:
1. That the Earth is warming.
2. That man is the cause of this warming, and that were it not for man, the Earth wouldn't be warming.
3. That this warming will lead to a catastrophe in the near future.
You have to believe all three.
I've studied this a bit and have spoken with scientists about it, and here is what I think:
1. The Earth is warming. We had what is known as "the little ice age" in the 19th century. The globe is in a natural period of warming as we are coming out of this so-called little ice age.
2. Man is obviously the cause of man-made pollution. There are plenty of good reasons why we should try not to pollute unnecessarily without having to make up fictitious reasons. ie. preservation of wildlife and fish in our waters, having clean water to drink, preserving the natural beauty of the planet, reducing asthma causing smog, etc.
3. Some people in the scientific community are beginning to understand that carbon emissions actually cause the planet to cool, not warm, and thus have replaced the term 'global warming' with 'climate change'. They do this rather than acknowledge their mistake. There is no reason to believe that carbon emissions will cause an environmental, Earth destroying calamity. Again, it would be prudent not to pollute unnecessarily for a number of other reasons.
