Advancing Freedom With Data: Debunking Catastrophic Greenhouse Warming
CO2’s greenhouse effect is the result of its interaction with the infrared of the electromagnetic spectrum, which is now largely saturated at today’s CO2 concentration of about 420 parts per million (ppm), say William Happer and Richard Lindzen. With so little unaffected infrared radiation left to interact with CO2 molecules, adding more of the gas is having a trivial effect and will produce even less warming in the future.

A revealing graph from Drs. William Happer and Richard Lindzen advances freedom by dismantling the false narrative that blames CO2 for an impending climatic catastrophe. Policies rooted in this alarmism—net zero mandates, energy restrictions, subsidies for wind and solar, and regulatory overreach—have been devastating to America and many other countries.
These mandates have forced electricity and fuel prices to skyrocket, closed reliable power plants, outsourced manufacturing jobs, and burdened families and businesses with higher costs of living. While delivering no environmental benefits, climate policies have contributed to energy poverty, a less reliable power grid, and a transfer of wealth from working families to government-favoured industries.
Drs. Lindzen and Happer, physics professors emeriti at Princeton University and the Massachusetts Institute of Technology, respectively, show through their new graph (below) how CO2’s warming power decreases very rapidly with increasing atmospheric concentration.
CO2’s greenhouse effect is the result of its interaction with the infrared of the electromagnetic spectrum, which is now largely saturated at today’s CO2 concentration of about 420 parts per million (ppm). With so little unaffected infrared radiation left to interact with CO2 molecules, adding more of the gas is having a trivial effect and will produce even less warming in the future.
These facts of atmospheric physics complement the CO2 Coalition’s messages about the benefits of carbon dioxide and the fossil fuels that emit it:
- CO2 is plant food necessary for life, not pollution. Atmospheric levels remain historically low by geological standards. Elevated CO2 has fuelled global greening, increased crop yields, and improved food security for billions.
- Fossil fuels have powered unprecedented human prosperity while causing no detectable rise in extreme weather, or in damages from it, when adjusted for population and wealth.
- Water vapor and clouds dominate the greenhouse effect; as a trace gas, CO2 is a minor player. Natural factors like solar variability exert far stronger influence.
Climate policies, sold as saving the planet, have instead restricted access to affordable energy—the foundation of modern freedom. They limit mobility, economic opportunity, and personal choice, especially harming the world’s poor. By contrast, embracing abundant, reliable energy from fossil fuels and advancing nuclear power allows societies to flourish, innovate, and adapt.
The CO2 Coalition, a group of more than 200 independent experts, exists to restore scientific integrity. Their work shows that real-world observations are consistent with research in saturation physics, not flawed computer models predicting catastrophe. Dismissing this evidence, as alarmists do to justify an agenda of government control, undermines free inquiry, open debate, and honest governance.
This chart is a tool for freedom. It equips citizens to question expensive, ineffective policies and demand evidence-based decisions. More CO2 supports thriving ecosystems and human advancement. Rejecting alarm-driven restrictions restores energy sovereignty, economic vitality, and individual liberty.

The IPCC’s doomsday scenario is dead, but not yet buried
Finally, the IPCC’s doomsday scenario is being tossed in the trash. The Dutch newspaper De Volkskrant deemed the news important enough for the front page. Marcel Crok wrote as early as 2018 that the IPCC’s extreme scenario was untenable. However, the wheels of science turn slowly, and so it took more than eight years for this insight to be recognized by the scientific community.
Samuel Furfari on COP’s and climate policy: “Just blah blah”
In a recent podcast with Tom Nelson, energy expert Prof. Samuel Furfari speaks about the nonsense of COP’s and of climate policy in general. But he is also cautiously optimistic about the future: “If the next UN leader comes from Africa or Asia rather than Europe, they may adopt a more pragmatic and ‘sober vision’ of climate policy.”

South Korea must end sacrificing growth, stability, and innovation at the altar of unverifiable climate fantasy, says Vijay Jayaraj. The country remains dependent on fossil fuels by necessity.
