How Old Is the House
Conflicts in Science by Royal T. McArdell
About the Book: How Old Is the House challenges many popular beliefs about scientific theories and scientific issues. Arguments both for and against popular theories and issues are presented so that you can make your own decisions as to what to believe. The Introduction is about a house that is either new or 150 years old- perhaps you can figure it out.

More Carbon Dioxide Please
The amount of carbon dioxide needed in the air for optimum plant growth is about two and one-half times greater than the current atmospheric level according to a fact sheet from the Ministry of Agriculture in Ontario, Canada. Greenhouse operators routinely add carbon dioxide to enhance plant growth which is one reason why it is called a greenhouse gas. The amount in the atmosphere has increased by about thirty percent since the1940’s, and studies indicate that the amount of carbon dioxide in the air is currently increasing at the rate of about 1.5 percent per year.
The Petition Project, an independent study of increased carbon dioxide levels and endorsed by over 17,000 individuals, many of them scientists, concluded that atmospheric carbon dioxide levels generally rise as the oceans become warmer and that the additional amount from human activities “is a wonderful and unexpected gift from the Industrial Revolution.” Plant, tree and animal life all benefit from the increased values. The opposite view is held by The Intergovernmental Panel on Climate Change (IPCC). They report that carbon dioxide is one of the major contributors to global warming and that the amount of carbon dioxide in the atmosphere should be reduced.
Carbon dioxide is a colorless, odorless transparent gas. Plants and trees absorb carbon dioxide from the air and give off oxygen as they grow. Carbon dioxide is added to greenhouses by burning natural gas, propane or injecting pure carbon dioxide gas. Without the additional carbon dioxide, ambient levels in a greenhouse can drop down to near 200 ppm (parts per million) during the day as plants absorb carbon dioxide from the air, and plant growth will nearly come to a halt.
Carbon dioxide now makes up about 0.036 percent of the atmosphere or 360 ppm. Most vegetation including trees can grow up to fifty percent faster if the level is increased to about 900 ppm and levels must rise to about 5,000 ppm to be harmful to humans. This means that the amount of carbon dioxide in the air would have to be about 14 times greater than the current level before it would harm people. The modest increase in atmospheric carbon dioxide over the past 60 years does not appear to justify the scary scenarios and drastic solutions to reduce carbon dioxide emissions as proposed by the IPCC.
