One side has an incredible amount of evidence, consensus and a consilience stretching back into the 1980's
LOL, 34 years research.
Google Grand Canyon.Here is a snippet from one search.
Geologists have this question pretty much wrapped up, aside from some missing layers, or unconformities, that have been completely eroded away. Again there were a number of forces at work and this is where
continental drift, vulcanism and climatic change come into play.
The fact that the Earth's continents are not fixed in place but rather float on a sea of molten rock, means that they move around quite a bit, relatively speaking. The surface of the Earth is composed of about twenty of these "plates" which form its crust. Seven of these plates are very large and consist of entire continents or sea floors and the rest are smaller in comparison. The plates are average out to be about 50 miles or 80 kilometers thick and float on top of the Earth's mantle. The plate which contains the Grand Canyon, the North American plate, was at one time considerably further south than its present location and therefore had a much different climate. In time it has gradually moved north and rotated about ninety degrees to its present location and configuration.

Make sense to ask a Geologist than a Scientist on Climate change, as Geologist look back thousands upon thousands of decades
before man and machinery arrived.
Grand Canyon is only one place where they can easily see Earths History as the Colorado River exposes the different Climates that Earth has gone through.
34 years is less than a blink in it's history.
There are many other sites on the Internet, so Google an get educated.
