The United Nations and nearly 100 climate scientists from across the globe have issued their latest environmental primal scream. Thanks to climate change, the planet is evidently on a path of “unprecedented environmental destruction” that will destroy life on earth as we know it.

Within a generation we’ll be overwhelmed by catastrophic wildfires, rising sea levels, floods, hurricanes, disease, food shortages and a mass die-off of coral reefs.”

There hasn’t been this much doom and gloom packed in a government report since Jimmy Carter was in the White House and issued the “Global 2000 Report” which predicted a coming Malthusian scarcity.

People can make up their own minds about the veracity of these latest predictions. But we already know that one conclusion of the UN report is dead wrong. This is the script that the United States, and particularly President Trump, is the environmental Darth Vader here.

The Los Angeles Times put it this way: “The report serves as a stark reminder of President Trump’s status as a global outlier in terms of climate change . . . Trump has rejected the 2015 Paris agreement signed by 195 nations to mitigate greenhouse gas emissions, expressed skepticism about human-caused climate change and vowed to increase coal-burning.”

Wait a minute. In 2017, the country that reduced its greenhouse-gas emissions the most wasn’t Canada or Britain or Germany or Australia or France. It was the United States. That’s right — the one country that pulled out of the phony Paris Climate Accord reduced its carbon emissions by 0.5 percent, the most of all major countries.

That’s especially impressive given that our economy grew by nearly 3 percent. In other words, we had more growth and less pollution — the best of all worlds. The major reason for the reduced pollution levels is the shale oil and gas revolution that is transitioning the world to cheap and clean natural gas for electric power.

The world’s largest emitter of carbon dioxide, by far, is China. The Institute for Energy Research found that China produced almost one-third of the world’s total carbon emissions last year. India was No. 2 on this list, with 93 million metric tons of increased pollution. So how is America the villain here?

The latest data also prove that Trump has been vindicated in his decision to pull out of the Paris Accord. Trump predicted that other nations would cheat and all the costs would fall on the United States. He was right. According to a 2018 report from Climate Action Network Europe, “All EU counties are failing to increase their climate action in line with the Paris Agreement goal.”

Only five of the 25 major nations have even managed to reach 50 percent of their pollution-reduction promise.

One country far below its target is France. Yet French President Emmanuel Macron, a major champion of the Paris accord, tweeted that the UN report proved that since “we have everything we need to combat climate change,” all nations must “act now!” Perhaps what he means is everyone has to act except for France — which isn’t taking action. The world is filled with climate-change hypocrites who want America to pay all the costs and make all the sacrifices.

The complete collapse of the Paris Climate Accord points to the impotence and incompetence of global organizations like the United Nations. Does anyone honestly believe that international bureaucrats and self-righteous politicians are going to somehow change the temperature of the planet, stop the rise of the oceans and prevent hurricanes?

The best way to combat climate change, as with all environmental challenges, is through more technological advancements that will find ways to stabilize the earth’s temperature. If we have to depend on the United Nations and global politicians, the planet really is doomed.
