What do folks here think about climate change? Is it insignificant, we need no action, or is it something which should be addressed with urgency?

Below is a link from NASA, I comment on the 400,000 year graph:

No emotions, no gut feel, no opinion, just a pure mathematical analysis from me says the following:
1.) Mother earth seems to manage a pattern which can be related to SPC (Statistical Process Control, how us Engineers automate a process to run between upper and lower tolerance limits. Like traction control on your bike, or speed control in your car, as two examples of millions)
2.) Based on the above, for almost 400,000 years (Samples available 800,000 years back) she had CO2 levels in control between 180 lower limt and 280 upper limit ppm. (parts per million)
3.) In process control we would use a closed loop PID (Potential Integral and Derivative) to manage that. Mother earth seems to have done that for most of the 400,000 years shown in the graph, within a range of 100ppm by controling vegetation and volcanic/lightning/burn activity. The process was pretty much in control until 1950. We can assume that mother nature when supplying too much oxygen made the planet more flamable and when supplying too much CO2 accelerated vegetation growth. (Obviously that could be totally wrong, I am just digging for how she managed to accomplish that control. I am just a simple Engineer, not a climatologist, hence my math approach)
4.) The Industrial revolution started in 1760 and from 1950 onwards we see the graph climbing exponentially. Without any emotion, applying pure SPC mathematics the graph tells us that that the range of 100ppm is no longer valid, the upper limit has been exceeded. In process control it means we have lost control.
5.) In process control, this would be a situation where we made and shipped 399,950 widgets in specification, and the last 50 widgets are out of specification and the scrap rate is growing exponentially. The question would be, when do we stop the production line?
