Nuclear Scientist Claims CO2 Is Not Responsible for Global Temperature Increases

Macdonald asserted that carbon dioxide (CO2) is not the main factor influencing changes in global temperatures.

“That’s precisely why you put your beer in the fridge,” he remarked. “If you want the fizzy drink to remain refreshing … putting it in the refrigerator helps the CO2 stay in the drink.”

He explained that this cycle varies every 100,000 years, with ice ages occurring when the orbit is most elliptical, resulting in significantly reduced solar heat and radiation.

Macdonald noted that this cycle, alongside the Earth’s wobbling and fluctuations in sunspot activity, serves as essential climate drivers.

“There’s nothing that can be done about that,” he stated. “That’s alright because, based on historical data, we can observe these maxima and minima cycles.”

He pointed out that during the Roman era, it was a maximum, with temperatures approximately two to four degrees higher than they are today, coinciding with significant advancements in civilization.

He stated that historical records show temperature variations have been considerable throughout history.

“As for the current temperature situation, we find ourselves about a quarter of the way up between the low minimum and the high maximum,” he explained. “Thus, we are still on the lower side of the scale, indicating we have a long way to go, with very slight changes—specifically, fractions of a degree centigrade.”

Macdonald explained that by utilizing spectroscopy to analyze gas bubbles trapped in Arctic ice, one can ascertain CO2 concentrations and corresponding temperature variations from different historical periods.

As a result, it’s feasible to calculate past CO2 levels and their related temperatures from thousands of years ago.

“If we go back over a hundred years, people were skating on the Thames in London. That period was referred to as the mini ice age, as temperatures had fallen significantly,” he said. “Currently, we are recovering from this mini ice age, with temperatures increasing as a natural course, unrelated to CO2 levels.”

Macdonald believes that all funds allocated to initiatives that attribute climate change to CO2 are politically motivated and that such resources should instead target more urgent societal concerns like healthcare and homelessness.

He contended that the data contradicts the claims made by the Intergovernmental Panel on Climate Change (IPCC), an agency of the United Nations that identifies CO2 as the main driver of climate change.

Should the IPCC’s theories be accurate, there would be evidence showing that CO2 levels rise first, leading to temperature increases, but Macdonald indicated that the causality relationship was not thoroughly investigated.

“I conducted that investigation,” he noted. “I discovered that temperature increases occur first, followed by CO2 emissions.”

Macdonald argued that the effects of CO2, methane, and nitrogen oxide are negligible.

He explained that as temperatures decrease, atmospheric CO2 diminishes since CO2 eventually combines with carbon ions to form limestone in the ocean.

Macdonald has aligned with the CO2 Coalition to disseminate factual information and resources about CO2’s essential role in the ecosystem, highlighting the shortcomings of climate models and the potential effects of enforced CO2 emission reductions.

He stressed that CO2 is not a contaminant; rather, it serves as a vital nutrient for plants and is integral to the photosynthesis cycle.

The coalition comprises professionals from various fields, including geologists, chemists, and physicists. Notably, Nobel laureate in physics John Clauser and renowned physics professor William Happer are members.

Macdonald announced that the CO2 Coalition has recently launched an educational program directed at K–12 students.

“There’s no single weather phenomenon on Earth; there’s a variety of weather patterns,” he remarked, noting the distinct differences in climate between San Francisco and Santa Clara, just 45 miles apart.

“Furthermore, climate is defined as the weather averaged over three months, resulting in various climate types, not just one.”

He concluded that policymakers need to reassess their condemnation of CO2, as excessively low CO2 levels could hinder plant growth, leading to widespread starvation and poverty.
