For the past five years, I’ve been watching and listening to this debate on global warming/climate change.
I told myself that when I retire (which I did), I was going to take a hard look into this very controversial issue to try and understand what it’s all about.
I spent months reading articles, books, watching interviews on TV with scientists, along with the many online videos from people in all fields of climate science, and visiting many websites about the climate.
I have corresponded with two Apollo astronauts who are knowledgeable on the subject. What I learned was encouraging.
1) The Earth has been warming since the last Ice Age ended. No surprise there.
2) CO2 is not a pollutant like some suggest but rather a life-sustaining gas that all life depends on.
3) The Earth’s temperature has risen slightly over the years but did so before CO2 rose and after the Little Ice Age ended.
4) As CO2 levels have risen so has food production and the greening of our planet.
5) As the Earth has warmed, sea levels have risen slightly due to some ice melt and the ocean waters expanding (which is to be expected).
6) Once CO2 in the atmosphere drops to 150 ppm, life starts to die.
7) There have been several times in Earth’s history of warming and cooling and much higher CO2 levels in the atmosphere before humans.
8) I could not find any evidence of severe weather increasing in intensity or frequency for tornados, hurricanes, droughts, or floods but rather the opposite.
9) From all I have read, many scientists say we are now entering a long, downward slide into a global cooling cycle that is not good for humans or the food products we depend on.
Of course, my research led me to some questions of my own. Here are just a few.
1) What should the ideal concentration of CO2 in the atmosphere be and why?
2) When climate change alarmists hold meetings and town halls, why do they avoid mentioning the past cycles of Earth’s warming and cooling?
3) Why do people who believe humans don’t contribute much in the way of CO2 get threatened with funding cuts or can only apply for grants that don’t allow for the study of natural climate cycles?
4) More people die from colder climates (Lancet Journal). So wouldn’t we want a warmer climate?
5) If climate science is settled as some think, then why do end-of-the-world deadlines keep changing?
6) Why did the Earth’s temperature stop rising, remain flat, or even cool in the past even when CO2 kept rising?
7) Former EPA Administrator Lisa P Jackson became the first federal official to declare CO2 a pollutant. If CO2 is a pollutant, why does OSHA say an employee in the workplace can be exposed to CO2 levels of 5,000 ppm during an 8-hour workday?
8) Why all the alarmism? Is it really about climate or is it about money, or power, or both?
9) And why does the U.N. IPCC alter final reports by leaving out scientists who state: “No study to date has positively attributed all or part [of the climate change observed to date] to anthropogenic [man-made] causes”. (“The Science of Climate Change, 1995″ IPCC Report)
These are just a few questions people should think about.
Ed Walbroehl spent 47 years in aviation, which included studying the weather as part of flight training, while his radar training in the U.S. Air Force that got him interested in weather. Climate has now become his main interest.
