When it comes to scientific predictions the best advice is, "Do not believe anything you hear and only half of what you see."
The overwhelming number of scientific projections over the years were absolutely and incontestably wrong. Scientist and research companies make their money primarily through grants. In order to get grant money, your have to come up with a either disaster theory or a potential miracle cure that sounds possible, but you need to grant money to prove the theory.
Scientists become famous for coming up with a theory that sounds plausible and generates grant money for hundreds or thousands of scientists.
No two of the predictions from hundreds of computer climate prediction models match. Doesn't that tell you that something is probably wrong with all of the models? Or that they are biased in favor of proving a theory?
In the 1970s, the majority of climatologists thought we were headed for an ice age. Read the original article in Time magazine from 1974.

One of the first things I learned when I took college-level science classes is that there is no such thing as a scientific fact. There are only theories that tend to explain things. A theory only lasts until a better theory comes along.
What I find most interesting about the global climate change debate is that it almost always ignores the most obvious cause. During the 1990s and up until the last solar max in 2000, the sun was putting out more energy than has ever been recorded. That also likely led to the opening of the ozone hole at the south pole, which we do not hear very much about it any longer. Why? The last article I read reported that the ozone hole was closing because the world banned CFCs. When they first proposed banning CFCs, it was going to take 50 years before we saw any results from the ban. The obvious cause was ignored because there wasn't anything that could be done about it.
Like everything else, if you want to know what is driving the scientific debate, you have to "Follow the money."
