Are you suggesting the climate is not changing?
Climate always changes. It's been changing ever since there was a climate and it will keep changing until the sun dies out.

Or that the changes we are experiencing are due solely to cyclical patterns and mankind is in no way responsible?
I had to break off this part from the preceding part, even though you tried to link them together.
So, exactly what changes are we experiencing that you think are extraordinary? By extraordinary, I mean that they have never occurred before in the last 4.5 billion years and are totally due to mankind's actions.

Perhaps Freon was not responsible for the hole in the Attic atmosphere. However, freon does destroy the natural ozone layer that protects us from ultraviolet light and, holes in it are bad for all life on the ground. That is the reason Freon is now banned as a refrigerant. A human created problem that, in addressing it, the ozone hole is shrinking.
This part is a display of wanton ignorance.
The "ozone hole" was discovered in the late 1980s when we actually attained the capability to notice something and measure it. This is a perfect example of a lot of hokum in "climate science." We only have about 30-40 years of decent measurements of stuff and yet we talk about everything being an issue that has never occurred before, ever.
Freon is a CFC, chlorofluorocarbon (I hope I spelled that right, I was doing it from memory.) It was blamed to the "ozone hole" that was discovered in 1979. Let's talk about ozone for a second. Ozone is O3 and the stratospheric ozone is formed by the interaction of sunlight on the fringes of our atmosphere. Ozone is a very reactive molecule and likes to play with just about anything else. It has been postulated that chlorine (and bromine) from the CFCs are reacting with O3 and transforming it into something else, thereby "destroying the ozone." Free ozone in the stratosphere blocks the incoming and active UV-A and UV-B radiation coming in from the Sun, so we don't get those harsh rays on us to cook us and other things. CFCs are not the only source of chlorine, it's found in the oceans in vast quantities as sodium chloride, AKA salt. There are storms out in the oceans. The "ozone hole" is not shrinking. It's been the same size and fluctuates around that size ever since it was discovered in the late 1970s. There's even a NASA site that tracks it.
I'm not going to get into the various misconceptions about UV-A, UV-B and different latitudes, and so on. but suffice it to say that it was a non-issue that was addressed at great expense and nothing really came out of it.

I believe mankind is contributing to climate change, exacerbating natural cycles in ways that greatly accelerate change inamical to life as we know it. I believe we have created an engine of change we cannot control.
Thank you for sharing your opinion. I happen to believe somewhat differently. I'm always quizzical as to why people have to falsify the records and the observations and lie in their reports to make us believe everything is going to hell.
Finally, I will start believing catastrophic anthropogenic global warming is a problem when the folks who tell us CAGW is an issue start acting like it's an issue.
