Paris Agreement tour 'a lot of hot air'

House Speaker Nancy Pelosi (D-California) is in the group of Americans that made the trip. In fact, Pelosi led a group of Democrats to Spain.

"It is a privilege to accompany a high-level Congressional delegation to Spain to combat the existential threat of our time: the climate crisis," Pelosi said in remarks published on USAToday.com.

Steve Milloy of JunkScience.com cannot help but laugh.

"It literally is just a lot of hot air," says Milloy, author of Scare Pollution, Green Hell, and Junk Science Judo. "She calls it an existential crisis, Biden calls it an existential crisis, [and] the Europeans, they're out of their minds about it, yet none of them are doing anything about it."

Forget about the fact that people sounding the alarm over emissions flew all over the world to discuss emissions as a driver of man-made climate change; Milloy says none of the Paris signatories have done anything to reduce emissions. 

"Emissions are just never going down, and you can only conclude from this that the whole purpose of the exercise is a political power grab," he decides. "No one anywhere in the world is reducing their lifestyle to meet the alleged goals of the Paris climate accord, which I like to call the Paris climate hoax."

Participants at the climate conference plan to discuss the Paris Agreement, including the Trump administration's ongoing departure from it.

This is among the first gatherings of governments and politicians since teenage climate activist Greta Thunberg scolded members of the UN for not doing enough in her mind to combat what she believes is man-made climate change.
