This week, many Democrats running for president appeared in a marathon CNN town hall to demand sweeping, urgent action on climate change, but a leading climate scientist says it's little more than hot air.

Over the course of several hours, former Vice President Joe Biden endorsed shutting down all coal-fired power plants.  Sen. Kamala Harris said she would ban fracking.  Sen. Bernie Sanders vowed to expand abortion to control the population.  And former Rep. Beto O'Rourke claimed he told his son their hometown of El Paso, Texas, would soon be uninhabitable.

"This is pure alarmism based on absolute ignorance," said Dr. Tim Ball, former professor of climatology at the University of Winnipeg.  He is also the author of :The Deliberate Corruption of Climate Science."  

"These people haven't got a clue what they're talking about.  They don't even know the difference between weather and climate," said Ball.

Ball says candidates like Harris and Biden - and the others - are attacking coal and fracking because their entire climate agenda consists of the assumption that carbon dioxide is the problem and we have to stop burning it to fuel our society.

Listen to the entire podcast as Dr. Ball explains where the Democrats base their argument that we have only eleven years to do anything about the "climate crisis" and why the science behind that conclusion is bogus.  He also reveals which direction the earth's temperature is quickly heading, and it's not what the activists would have you believe.
