Environmentalists and certain political factions have been stumping hard since the 1990s to impose a theory of climate change as fact. Rational thinkers understand that a theory is, essentially, a guess. Hopefully, it’s an educated one.
When a scientific theory is based on inaccurate facts (data), it loses its credibility in the professional community. As L. Gordon Crovitz put it in the February 2010 Wall Street Journal:
“Skeptics don’t doubt science – they doubt unscientific claims cloaked in the authority of science.”
The ancient Greek philosopher Heraclitus said, “Change is the only constant in life.” That was about 500 B.C.
Truer words couldn’t apply to climate speculation today: the only thing certain about climate change is that it goes on constantly.
So, very few people who concern themselves with climate change doubt that’s it’s happening. The question is: why?
What causes climate change? Global warming alarmists state as fact that carbon dioxide (CO2) and other greenhouse gas (GHG) emissions burned by humans are being trapped in the atmosphere rather than venting into space, thereby creating the “roof” of a high-altitude “greenhouse.”
This is a wonderful theory. But it comes with punitive consequences for the fossil fuel industry. Countries around the world, particularly members of the European Union (EU) are grappling with United Nations-promoted “global sustainability guidelines” that demand aggressive GHG reductions to avoid unpleasant governmental consequences.
There are many other perfectly fine theories of climate change that get virtually no press. People formulating these scientific guesses typically believe one of two things:
- Earth’s overall temperature is heating (threatening all life as we know it)
- Earth’s overall temperature is cooling (threatening all life as we know it)
Most climate change researchers do agree that the planet is going through a warming trend but a few warn we are on the front (or back) doorstep of a Mini-Ice Age.
While global warming caused by excessive GHG emissions is a fine theory, flaws in the science behind it came to the forefront in early 2010. A series of disclosures revealed that some findings by the Intergovernmental Panel on Climate Change (IPCC) included errors such as projecting that the Himalayan glaciers could melt by 2035.
There are other views on climate change. One is that it is completely natural and independent of human activity.
A 2007 review of 500 scientists by analyst Dennis Avery and climate physicist Fred Singer concluded that those experts doubted that climate change was due to human-made greenhouse gases. The majority agreed that climate change is much more likely to be part of a cycle of warming and cooling that has happened regularly every 1,500 years for the last million years.
The scientific review identified the most recent global warming, from 1850-1940 and, therefore, was probably not caused by humanity’s greenhouse gases.
Historical evidence supporting the natural cycle theory include:
- A record of floods on the Nile dated about 5,000 years ago
- The Romans wrote about growing wine grapes in Britain in the first century AD until it got too cold during the Dark Ages
- Tax records show the Britons grew wine grapes in the 11th century, during the Medieval Warming (approximately 900 to 1250), until it got too cold during the Little Ice Age (1275 to 1300)
- Thousands of museum paintings show brilliantly blue, sunny skies during the Medieval Warming and more clouds during the Little Ice Age.
The 500 climate change articles cited evidence in the current warming cycle of:
- Fewer and milder storms and droughts
- Corals, trees, birds, mammals, and butterflies are adapting well rather than dying off
- Sea levels are not rising significantly
After Avery and Singer pored over the scientific reports, they published a book in October 2006, Unstoppable Global Warming: Every 1,500 Years, which countered claims made by former U.S. Vice President and lead climate alarmist Al Gore in his earlier 2006 book and film An Inconvenient Truth.
Singer said that global warming “can all be explained by the Sun’s activity,” adding:
“The number of the Sun’s cosmic rays hitting the Earth affect the number of low, cooling clouds that reflect solar heat back into space, amplifying small variations in the intensity of the Sun.”
Persistent and troubling doubts raised since 2007 about the trustworthiness of climate scientists have not been lost on policymakers who oppose international and domestic climate change policy. For example, U.S. President Donald Trump withdrew his country from the UN Paris Climate Agreement in 2017 because it would undermine the national economy put the U.S. at a permanent disadvantage.
