The problem is that climate is a very difficult thing to predict, and is probably beyond our present science. There are too many combinations of variables and most of them are unknown. Ask a liberal who claims global warming is settled science to explain the butterfly effect. His typical flustered and incorrect response will demonstrate how much he knows about science related to climate.
Watch the video!! It turns out that the Sun is a finely tuned machine. Several circulating currents beat together to make the magnetosphere seem chaotic.
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.
