Considering the climate problems that can result due to CO2 increases, we are doing a terrible job of limiting CO2. I doubt we every be able to control climate. We may be able influence it but not really control it.
The problem is we can't control Co2 either. God does.
So given the trillions that were already spent on this farce, and it's proven to be a failure, how much more should we spend?
This all reminds me of what happened (and is still happening) here. Years ago the feds said our air was unacceptable. So they forced us into this E-check program. Ten years later, they once again tested the air with no change in the quality of air. And keep in mind, during that time, our steel mills shutdown. They reopened again later, but with much more green initiatives.
The billions we spent in that decade of E-cehck could have went to better things such as the homeless, our roads, reducing taxation, a number of things. But even after the negative results of this failed program, the feds insisted we continue it.
So all this goes to support my point. Combating global warming is a bottomless money pit. All the money in the country could never fill it.
"The definition of insanity is doing the same things over and over again, but expecting different results each time."
Man certainly can control the CO2 that he puts in the air. According to the U.S. Geological Survey, man is responsible for putting some 24 billion tons of CO2 into the atmosphere. This is only about 3% of total CO2 emission so it might seem insignificant but it's not.
The oceans, our forests, and the atmosphere has been a huge CO2 sink. They have absorbed enough C02 to keep our CO2 level in the atmosphere fairly stable for thousands of years before the industrial revolution.
With the industrial revolution, 3 things happens that effect C02 levels. We destroyed about 25% of the worlds forests which has reduced CO2 absorption. We are adding about 24 billion tons of addition CO2. And lastly, studies are showing that ocean absorption of CO2 is beginning to decrease. As a result we now have the highest level of CO2 in our atmosphere since humans began to walk the earth and there is no reason to assume it will not continue to rise.
I don't know anything about the effectiveness of vehicle emission testing in your state. However, in Washington State air quality is much cleaner than when the program began in 1982 due to programs such as emission testing and improvements in technology. As a result, the state is abolishing emission testing this year. One of the mangers in a state emission testing station said, "When we started testing in the 1980's, 1 out of ever 50 vehicles fail to pass. Today it's about 1 in 500. The emission control systems in cars today are so good and most of the old high pollution vehicles are gone, there isn't as much need for testing."
There is no federal requirement for emission testing. While the federal government's Clean Air Act stipulates air quality levels for the entire country, how these targets are achieved is left up to each state.
