How is it flawed? I am no expert on this topic.

As there are so many wrong information in the argument presented by warmists, I will just pick one of them now.
Carbon Dioxide:
"C02 is not a pollutant as Gore infers. It is, in fact essential to life on the planet. Without it there are no plants, therefore no oxygen and no life. At 385 ppm current levels the plants are undernourished. The geologic evidence shows an average level of 1000 ppm over 600 million years. Research shows plants function most efficiently at 1000-2000 ppm. Commercial greenhouses use the information and are pumping C02 to these levels and achieve four times the yield with educed water use. At 200 ppm, the plants suffer seriously and at 150 ppm, they begin to die. So if Gore achieves his goal of reducing C02 he will destroy the planet." - Tim F. Ball, Ph.D. Climatology
"Carbon dioxide is not a pollutant but a naturally occurring, beneficial trace gas in the atmosphere. For the past few million years, the Earth has existed in a state of relative carbon dioxide starvation compared with earlier periods. There is no empirical evidence that levels double or even triple those of today will be harmful, climatically or otherwise. As a vital element in plant photosynthesis, carbon dioxide is the basis of the planetary food chain - literally the staff of life. Its increase in the atmosphere leads mainly to the greening of the planet. To label carbon dioxide a "pollutant" is an abuse of language, logic and science." - Robert M. Carter, Ph.D. Professor of Environmental and Earth Sciences, James Cook University
"Carbon dioxide is not a pollutant. It is a colorless, odorless trace gas that actually sustains life on this planet. Consider the simple dynamics of human energy acquisition, which occurs daily across the globe. We eat plants directly, or we consume animals that have fed upon plants, to obtain the energy we need. But where do plants get their energy? Plants produce their own energy during a process called photosynthesis, which uses sunlight to combine water and carbon dioxide into sugars for supporting overall growth and development. Hence, CO2 is the primary raw material that plants depend upon for their existence. Because plants reside beneath animals (including humans) on the food chain, their healthy existence ultimately determines our own. Carbon dioxide can hardly be labeled a pollutant, for it is the basic substrate that allows life to persist on Earth." - Keith E. Idso, Ph.D. Botany
The above few quotes are easy to understand, right? |
