I think this may be well off topic, but this "natural climate progression" trend is absolutely correlated with our entry into the industrial revolution and ICE transportations past that.

You can clearly see the spike, and this data is a few years old. Yes, the earth goes through climate changes, but we are going through one at a scale and speed the planet as never seen as far as we have been able to record thus far.
Now, you can argue that diesel trucks aren't to blame for this. Fair argument. You can argue that you don't trust the science for one of a number of reasons, also fair but I'd ask why you trust that the planet has gone through changes at all if you find the data so untrustworthy.
And, just to hit off any comments around the scientists models changing so much. It's not at all shocking that climate models are so far off considering the number of variables that need to be taken into account, the fact they are always changing, and we are bettering our knowledge.
I'm not saying we should just shut down the global economy and live like cavemen, but it's foolish to ignore this. If scientists are wrong and this isn't an issue, then we have only learned how to create better energy sources (eg. solar, nuclear, etc.) and if we are right, well maybe we save ourselves from extinction or from losing the planet as we know it.
This is not to say that batteries are the answer (lots of issues in their current state), or that solar or wind are the direction forward (solar relies on batteries, plus it's not super efficient yet, wind has tons of issues), or anything like that. That said, if we don't invest in them, they will never get better. The original automobiles were slower, less reliable, and more expensive than horses. I'm sure glad that we continued to explore them as a viable option.
Try and not let yourself get caught in only looking at the surface, or just believing some singular side of a political/scientific debate because it aligns with your worldview. Not saying that is what you're doing, but I find it's a helpful reminder.
End my rant.
