The climate has always been changing, yes. That it is changing more rapidly than in the past is most likely due in part by human activities, according to climatology.
There is no evidence that supports the theory the climate is changing any faster or slower, than at any time in the past.
According to politics, of course, there is either a dead certainty that mankind is ruining the planet, or no possibility at all that humans can affect the climate, according to what side you're on. Politics is good at creating BS.
Mathmatically, and logically, it is not possible for human made CO2 to cause anything close to warming, or cooling trends, we have seen. Less than 1% of the entire earths atmosphere is so-called "green house gasses". Of that, only 5% to 10%, of the green house effect is due to these gasses. Of the CO2 emitted into the atmosphere yearly, less than 5% comes from Human activite. When you work it out mathmatically, it works out to less than one tenth of one degree of temperurate change is due to humans.
In other words, less than what we could feel on human skin.
It does back up the somewhat alarming proposition that the climate of the Earth is changing in ways we really can't predict very well.
What really needs to be done is to study climate change so that we do have some idea what to expect. Even if "most likely due in part" becomes "for certain anthropogenic", there really isn't much we can do about it at this point anyway.
Most of the climate models that claim human made CO2 is causing changes in the climate, have all failed when the theory is tested. CO2, if it was the source of warming, would cause the mid-atmosphere to warm, after all that's where the CO2 would be absorbing the most light. However, all attempts to collect temp data from this area of the atmosphere have shown zero real change in temp. In other words, it's all bogus.
