I assume everyone has heard by now that the "Paris Climate Accord" President Trump announced he is pulling out of was actually nothing but a publicity stunt engineered by Barak Obama that didn't obligate the United States or any other country to reduce greenhouse gasses by one iota.
Although Obama left office with a reputation as an environmental president, during his tenure the concentration of Co2 and other greenhouse gasses in the atmosphere increased at the same rate it had been increasing before that, and if anything sped up, and a big reason is that every year Obama would go to that climate summit in Paris and make sure the final declaration didn't contain any language that obligated anybody to do anything to reduce greenhouse gasses. They agreed instead that each country would voluntarily come up with their own greenhouse gas and pollution "targets."
The conventional wisdom for why Obama did that is that since he knew he'd be judged by how the economy did while he was in office and not by the amount of greenhouse gasses in the atmosphere, he wasn't going to do anything that would hurt the economy such as impose regulations on the business world. That's correct except that Obama did it not so much to help the economy as to make sure he didn't interrupt the flow of campaign cash from Wall Street and big corporations into the accounts of the Democratic Party, the same reason he did everything else, the same reason he never allowed any legislation to be introduced that would increase wages or strengthen unions or in any other way redistribute any wealth back into the accounts of the people whose labor had originally created it. Conservative Democrats like Obama, the Clintons, and the kind we have in New Mexico decided a long time ago that they'd try to cling to power by doing the bidding of the wealthy, and an affluent layer of feminists, Blacks, gays and other identity politics adherents, instead of serving the interests of the mass of working class Americans.
Note: One of the big environmental groups is 350.org. They want to decrease
the concentration of carbon dioxide in the atmosphere until it's down to
350 parts per million, or 350 ppm. As of now it's at 409 ppm. Below are two graphs that show how CO2 concentration has increased in recent years and over the long haul.
