For about 20 or so years we had emissions testing here too. It helped get the worst of the old oil burners off the road and forced others to clean up by getting cars tuned etc. We have phased it out now that there are very few older cars left on the road and the new ones are so very much cleaner and stay that way with much less maintenance.
It was not worth the cost of running the testing centers under the new circumstances.
However, I just had a thought. Are we getting by without screening for polluting cars because of rules and testing done in so many other places that keep the on road fleet cleaner for us. Are we sort of being anti-vaxers?
The July average temperature across global land and ocean surfaces was 1.46°F (0.81°C) above the 20th century average. As July is climatologically the warmest month for the year, this was also the all-time highest monthly temperature in the 1880-2015 record, at 61.86°F (16.61°C), surpassing the previous record set in 1998 by 0.14°F (0.08°C).
And what is wrong with what I gave you as a definition? As well, which of the above facts to you disagree with?
The foundation is: 1. CO2 is a 'greenhouse' gas -- that is, it tends to trap heat in the form of IR radiation. 2. We humans have been releasing large amounts of CO2.
Those are simple, clear facts. Do you disagree?
And slightly, but only slightly, less simply the amounts of CO2 that we have been freeing are large enough to affect the heat balance of the earth in the direction of warming. This too is a fact. So there is man made global warming. How much precisely you can now argue about with good math.
Because I'm 65, and I know that Medicare isn't free. I've paid into it for 47 years. If suddenly everyone under 65 gets it, it will be free for many of them, and it will cheapen what I get after paying into it all this time.
If your care and concern for future generations didn't tell us just what kind of person you are this sure does.
