The best available peer-reviewed science - reams of it - indicates that the climate is changing for the warmer and that human actions, to wit the burning of fossil fuels, is a cause of that change, at least in significant part.

To deny that overwhelming evidence, which has been amassed by the best climatologists in the world, is foolish and intellectually dishonest. The conclusions of peer-reviewed science should always be taken seriously, though not unquestioningly, because of the safeguards built into the scientific method. And the scientific method always works.

The process of peer-review in academia, be it in the hard sciences like chemistry, physics or geology, or in social sciences such as poli sci, psychology or economics, is to insure integrity by evaluating an article in terms of the best practices available in the discipline at that particular time.

The scientific method is self-correcting because it is always open to what is accepted as true today being disproven in the future as a greater base of knowledge is amassed. While this is most demonstrably true in the hard sciences, it is also true in the softer sciences such as psychology. 100 years ago phrenology was taken seriously and it has been decades since that has been true. Experimentation and observation proved it to be false and psychology moved on. Hypothesizing things that can be tested and observed has been the hallmark of the scientific method since at least Galileo.
