International Climate Conference Debunks Science and Policy Consensus Claims

By H. Sterling Burnett, Heartland Institute

The Heartland Institute partnered with the Germany-based European Institute for Climate and Energy (EIKE) and the U.S.-based Committee for a Constructive Tomorrow (CFACT) to hold a two-day climate conference on June 14-15 in Vienna, Austria. This was the 16th International Conference on Climate Change; Heartland has either hosted or participated in all of them.

The speaker’s line up for the conference was outstanding, boasting some of the world’s top climate scientists, and economic and policy experts, including Heartland’s own President James Taylor, not long after a successful European trip during which he provided invited testimony on climate change to the European Union Parliament. Within days of Taylor’s presentation, the EU Parliament rejected a bill to require net-zero carbon dioxide emissions throughout Europe.

Since that time, new EU elections have been held, and a number of climate skeptics replaced Green party representatives in the EU parliament.

The climate conference was the first of its kind to take place in Austria, whose populist conservative Members of Parliament wield increasing influence within the EU Parliament.

As I write, videos of the conference sessions have not been posted; but below, I categorize and note some of the speakers and topics, and Taylor has provided brief descriptions of a few of the talks. On the science front, an international group of scientists, including Nicola Scafetta, Ph.D., Willie Soon, Ph.D., Nir Shaviv, Ph.D., and Henrik Svensmark, Ph.D., discussed the role the sun and cosmic rays play in warming and climate change. William Happer, Ph.D., described the role that clouds play in radiation transfer. Roy Spencer, Ph.D., discussed the idea that temperature extremes are becoming more common. Taylor, Craig Rucker, and Nobel Prize laureate John Clauser, Ph.D., each discussed how climate alarmists and the media are lying, either directly or through omission of key facts, to promote the idea of climate emergency in need of a big government fix—and discussed ways to successfully debate and debunk their claims.

Other researchers discussed the science and politics of energy and climate change, including the potential of different energy sources and how and why climate alarm is being fought in legislatures and the courts. They included such analysts as Marc Morano, Marcel Crok, László Csaba Szarka, Ph.D., Bernhard Strehl, Ph.D., Manfred Haferburg, Douglas Pollack, and Benjamin Zycher, Ph.D.

Below, Taylor briefly describes the content and impact of a few of the presentations, including his own.

To a packed house at the conference hall in Vienna, I (Taylor) set the stage for presentations by some of the world’s most accomplished climate scientists and climate policy experts. I explained how climate alarmism is a Trojan horse for the global left to consolidate money and power in global government institutions while depriving us of our most basic freedoms. After congratulating the audience on sending even more freedom-focused policymakers to the upcoming EU Parliament session, I noted how Heartland is working closely with EIKE and other public policy organizations and policymakers throughout Austria and throughout Europe. I gave a presentation on specific examples of climate change misinformation making the rounds in the establishment media. I then turned the floor over to presentations by participating scientists and policy experts.

“No chance” was the key takeaway from a presentation by Dr. Will Happer. Happer and a colleague, W. A. van Wijngaarden, Ph.D., published a paper in 2020 showing the atmosphere has nearly reached its carbon dioxide saturation point. Carbon dioxide impedes the flow of longwave radiation to space within a specific spectrum range. At current atmospheric CO2 levels of approximately 420 parts per million, atmospheric CO2 is nearly saturated, meaning nearly all potential warmth retention from atmospheric CO2 has already occurred, such that additional CO2 emissions will have almost no impact on global temperatures. During his presentation, Dr. Happer said there is no chance that the saturation effect he documented could be wrong. From the humble and affable Dr. Happer, that is as forceful a statement as you will ever hear. That is good news for people worried about future climate change, and should end the debate about any future climate change crisis.

In a subsequent one-on-one conversation that I had with Danish scientist Dr. Henrik Svensmark, he confirmed Happer’s assessment of the CO2 saturation effect, saying, “Dr. Happer is correct, CO2 saturation as described by Dr. Happer is a well-known and well-understood matter of science.

“Nobody with any basic understanding of atmospheric physics can claim it is wrong,” Svensmark concluded.

Dr. John Clauser, the 2022 Nobel Prize winner for physics, gave a compelling blow-by-blow takedown of climate alarmism. Among other things, Clauser emphasized that the United Nations Intergovernmental Panel on Climate Change (IPCC) and its computer models are spectacularly wrong in their assumptions about clouds.

Clauser pointed out that average cloud cover throughout the planet is approximately 67 percent. IPCC claims clouds have an albedo of 0.34, meaning they reflect approximately 34 percent of sunlight back into space, with 66 percent of the sunlight that strikes cloud tops reaching Earth’s surface. In reality, Clauser emphasized, cloud albedo is approximately 0.80. The sun is a variable star, meaning the output of solar energy varies a significant amount. Compelling scientific evidence shows solar output has increased significantly during the 120-plus years since the beginning of the 20th century. Drastically underestimating cloud albedo allows IPCC to underreport the impact of the recent increase in solar output on global climate and allows IPCC to claim a much greater impact from carbon dioxide emissions than is justified by sound science.

Wish I could have been there. I’ll update readers when the videos are posted, so you can view them at your leisure.
