|CO2 -Good for you and for Giant Pandas too!|
Rising CO2 levels causes (sic) an enhanced greenhouse effect. This leads to warmer temperatures which has many consequences. Some effects are beneficial such as improved agriculture at high latitudes and increased vegetation growth in some circumstances. However, the negatives far outweigh the positives..
Human CO2 emissions over the past few centuries have upset this balance.
“atmospheric concentrations of carbon dioxide (CO2) in the Early Carboniferous Period were approximately 1500 ppm (parts per million), but by the Middle Carboniferous had declined to about 350 ppm -- comparable to average CO2 concentrations today!”
At a fundamental level, carbon dioxide is the basis of nearly all life on Earth. It is the primary raw material or “food” utilized by the vast majority of plants to produce the organic matter out of which they construct their tissues, which subsequently become the ultimate source of food for nearly all animals and humans. Consequently, the more CO2 there is in the air, the better plants grow, as has been demonstrated in literally thousands of laboratory and field experiments (Idso and Singer, 2009). And the better plants grow, the more food there is available to sustain the entire biosphere.
“Carbon dioxide is an aerial fertilizer that provides many beneficial impacts.”
“You can look at thousands of studies – real world data studies that have actually been conducted that demonstrate beyond any doubt that higher levels of CO2 are going to increase the productivity of plants.”
“They’re real. They’re not imagined. They’re not projected. They’re real, and they’re occurring now.”So, are HIGH levels of CO2 harmful?
From the Paleozoic Period in the graph above, we see that the Earth has survived 7000 ppm. Before the US Senate, William Happer testified: (here)
Focusing on carbon dioxide, which according to Harris is not a pollutant….
In fact we are seeing a ‘greening,’ where deserts are actually retreating, forests are expanding, and we're seeing more habitat for wildlife. It's actually a good thing that this kind of climate change is occurring."There is not a single instance of CO2 being a pollutant. Ask any chemistry professor. The only thing being polluted is your mind or the minds of your children. (link)
