In a couple of months the weather will "change".
If the climate was changing we wouldn't have the repeating patterns over 4.5 billion years.
Seasons are not “climate change”. So, we’re not talking about Spring, Summer, Fall and Winter, when talking about Climate Change.
And then, Climate Change is not restricted to some long cycles, even if we’re talking about a cycle that has a period of a thousand years or more. Some of climate change may relate to some long term cyclical patterns, over decades or hundreds of years ... but other climate changes are catastrophic and not cyclical ... an example would be massive volcanic activity, and that’s not necessarily cyclical. Another would be large meteor strikes upon the earth. Those are random and not cyclical.
Then you have the worldwide flood which produced the biggest climate change of all time, and drastically affected the (i.e., “climate change”) and was a “one-time event” never to be repeated again.
Climate change can come from catastrophic events, one-time events, some from cycles and then a variety of random causes ... thereby yielding no pattern at all to “climate change”.
