Donald Trump has announced he will pull the United States from the Paris climate accord.
The decision, which comes from an administration with virtually no science advisors, runs counter to pretty much every other industrialized country in the world and a 5-to-1 consensus among voters that we should stay in the agreement.
The Paris deal is a voluntary agreement, signed in 2015, in which 197 countries agreed to try to reduce their carbon dioxide emissions with the goal of keeping global warming under 2 degrees Celsius (3.6 degrees Fahrenheit).
Trump's decision did not go unnoticed on Twitter, where people rained down fire.
Multiple people covered the crowds that were gathering outside the White House.
Elon Musk, who had threatened to leave Trump's presidential council if we left Paris, jumped in:
And Leo DiCaprio gave some advice for all who were shocked and upset by the news.
Meanwhile, news organizations provided some helpful context.
CNN introduced America to our illustrious new group of neighbors.
The only two countries that didn't sign were Nicaragua, which actually wanted to do more, and Syria, which is the middle of a civil war.
In what must have been one of Trump's proudest sound bites, he said he was elected to represent Pittsburgh, not Paris. Some people couldn't resist pointing a couple things out.
Including the city's mayor.
Other local and state level government officials also joined in, letting the country know that they're committed to Paris, no matter what Trump says.
Both New York Mayor Bill de Blasio and New York Gov. Andrew Cuomo made sure their city and state knew they were in this for the long haul, as did Gov. Jerry Brown in California.
Bernie Sanders also chimed in.
Barack Obama, who signed the agreement back in 2015, called on everyone to do their part.
"I'm confident that our states, cities, and businesses will step up and do even more to lead the way," the former president wrote.
The message is clear. This was a dumb move, but the Paris agreement — and the hopes and drive behind it — will survive.
The European Union and China as well as numerous American states and cities have all vowed to abide by the plan's regulations, no matter what Trump does on a federal level. The fact is, the U.S. is already shifting to cleaner fuels and renewables, and solar power now employs more people than coal.
Plus, the Paris climate deal is scheduled to come into force on Nov. 4, 2020. Coincidentally, right after the next Election Day.
