Heartland Institute counters climate alarmism at UN conference in Spain

President Donald Trump’s former top science advisor Dr. Will Happer headlined a lineup of climate experts speaking at The Heartland Institute’s climate realism forum at the United Nations’ Conference of the Parties (COP25) on December 3. The five-hour-long program was livestreamed around the world on YouTube from the Madrid Marriott Auditorium in Spain, where the COP was moved after unrest in Chile caused by rising fuel costs forced the venue to be moved from Santiago.

“The Heartland Institute was honored to present Dr. Happer at our prebuttal of the UN conference,” said James Taylor, director of Heartland’s Arthur B. Robinson Center on Climate and Environmental Policy. “Dr. Happer provided valuable insight into the powerful scientific evidence that shapes President’s Trump climate realism. Dr. Happer’s impressive scientific credentials and accomplishments are unsurpassed, and the world needed to hear Dr. Happer present the scientific case against a speculative and highly dubious climate crisis.”

Other speakers at Heartland’s climate realism forum included climate scientist Stanley Goldenberg, meteorologist Anthony Watts, Chilean scientist Douglas Pollock, European Institute for Climate and Energy General Secretary Wolfgang Müller, advisor to former British Prime Minister Margaret Thatcher—Lord Christopher Monckton, International Climate Science Coalition Executive Director Tom Harris, and Heartland’s James Taylor and Jim Lakely.
