If you look at the long term (pieced together proxy model of) Earth's temperature, you will find the temperature fall at each major volcano eruption time and time again. We are at an artificially cooler than normal time, for a peak temperature, preparing to begin the next ice age in few handfuls of thousands of years.

You have to remember that temperature proxies are only the history temp, assumed correct, tanking in one area. Then another area far away, maybe over lapping, maybe not. They then patchwork that together, mostly with computer models that are nonsense, and pretend they could know the total average Earth temperature at some given times in history. Their models ignore the too complex parts and assume the earth is flat, with no air going up into the sky...just a flat Earth that if you jump, you hit your head on the atmosphere.

Their most common trick, aside from framed charts starting at known lows in temperatures, is to confuse you into comparing regional temperatures with assumed average all of Earth temperatures; there is no real comparison, even assuming both were accurate. Even an ice age, just means the 'other' hemisphere is cold, while the opposing is hot. They've mostly traded places and the average total temp, mostly balances. Of course, they like to pretend short term weather trends are climate as well, instead of nonsense noise.

Oil, gas, and coal are massively entrenched industries. It is nearly impossible for a new competitor to enter the market. Most have invested half at century at least into entering the market. They must build infrastructure, spend lots up front, hoping to profit decades down the road, then also deal with massive regulatory burden costs. It is unquestionably a non-profitable industry, but it is required for society. We would have no plastic, electronics, many metals/other materials, many medications and lots more. Even coal has huge non energy uses. This necessity is why the governments partially subsidize them; mostly only making up for their own socialism-like regulatory capture of the market.
