Primarily it's about power (the political variety) and control.
People with abundant, reliable cheap energy will go and do whatever they want as they will be living prosperous lives (assuming they aren't dumb niggers). These people become harder and harder to control, so back in the 60s and early 70s it was decided that a crisis needed to be engineered in order to limit access to cheap reliable energy to the masses. This crisis was decided to be a "climate crisis" and the use of CO2 as the boggie man (though they did also try "the ice age cometh" and the acid rain scare, as well as the ozone hole scare first). See Club of Rome. Vast resources were then poured into "the science" and the formation of bodies like the IPCC, whose entire mandate was not to investigate how the climate works, but to research the human causes of "climate change", the outcome was baked into the cake and anyone who didn't tow the line would be defunded and discredited.
The satanic jews behind all this want total power. They are fully aware that their plans will likely result in the death of somewhere around 80% of Earth's population. They have no problem with this.
The "making people feel good" aspect is just one part of it. This is an effect of the psychological warfare that has been waged on the populations of Western countries for decades. Almost everyone (probably 90%) have been indoctrinated into a cult like belief system in which their empathy has been redirected away from their own kin and onto external factors, like "the environment" or "refugees".
The primary mechanism of this psychological warfare is fear. Most people are highly susceptible to fear based propaganda which is why it is so effective. Even people who do not fall for it on one particular subject (perhaps due to domain knowledge) may well do so on another. I have puzzled for some time over why so many are susceptible, and what makes those who are not seemingly immune from it. It's not intelligence, or lack of intelligence as far as I can tell. Equally intelligent people fall for the most obvious of propaganda. It's not courage. I certainly wouldn't classify myself as courageous, and yet I seem to find myself in a small group of heterodox thinkers. Perhaps it boils down to a belief or trust in authority? Those who believe that the "authorities" or "experts" are really there to help seem particularly vulnerable to being lead in any direction.
