Re: “Reduce carbon in a serious way,” p. 20, Dec. 25 Gazette
In the '90s environmentalists told us that due to the many jet aircraft flying around the world, their contrails would produce clouds, which would block sunlight getting to the earth causing it to cool.
This obviously hasn't happened. More recently, Al Gore predicted that global warming would cause the polar ice caps to melt, raising sea levels and flooding vast areas of low-lying coastal areas around the world.
Again, it hasn't happened. The environmental mob changed their tune when it was learned the earth's temperature hasn't changed in the last 10 - 12 years and now refer to it as "climate change."
Fear-mongering seems to be their stock in trade. One expert on the matter and those supposedly terrible carbon dioxide levels in the atmosphere – CO2 is not a greenhouse gas and is necessary for all life on earth – makes the claim that just one of the recent volcanic eruptions in Indonesia in just four days negated every single effort earthlings made to control CO2 emissions in the five-year period preceding the event.
At any given time there are 200 - 400 volcanoes active around the world, 20 in Alaska alone, spewing out crud. One of the more absurd statements I've recently heard is that "climate change" is somehow causing earthquakes and volcanoes. More fear-mongering.
It's interesting to note that the increase in global food production since 1976 has occurred in parallel with the rise in atmospheric CO2 and the doubling of the population.
For plants, carbon dioxide is a plant superfood and the amount of currently available atmospheric CO2 is insufficient to support the ever-increasing need for greater yields.
The current level of about 400 ppm is insufficient for the potential yield of current crop genetics; we will need to increase atmospheric CO2 levels just to keep pace with the rising food demand. It's interesting to note that greenhouse operators will often elevate CO2 levels to levels approaching four times (1,600 ppm) to meet the demands of their crops.
