The problem is that climate is a very difficult thing to predict, and is probably beyond our present science.

Not really.

The story of Earth's climate changes is preserved in the geologic record, which (real) climatologists have been studying for decades. That record shows a regular pattern of cooling and heating that can be dated to historical epochs.

A close perusal of that pattern reveals that our planet is now entering a solar minimum, where global temperatures drop dramatically.
