In 2015, United Nations officials and leaders from around the world congratulated themselves on the Paris Climate Accords, which committed nations to significant reductions in carbon emissions and compelled the wealthiest nations to help fund similar efforts in developing nations.

Now, just three years later, the UN says those commitments are not even close to sufficient to confront human-caused climate change, so they're asking nations to pony up even more resources to confront the threat to our climate.

So how did everyone get the price tag so wrong just a a short time ago and why is the estimate so much higher now?  We ask Rob Bradley, CEO at the Institute for Energy Research.

We also ask Mr. Bradley whether the French tax revolt is a sign that even liberal nations are fed up with the costly climate agenda, and whether there's any renewable source now or in the foreseeable future that could even come close to providing the energy we get from oil, gas, and coal.

Listen to the full podcast with Robert Bradley to get an informed update of where we really are in the energy and climate debates.
