[Mod Edit], co2, older Diesel engines

[azSkier]

I do understand your point. However, those plants are essential. The co2 from those plants will not be reduced by 50 pct in the next 8 years. I expect them to go after the soft targets.

You forgot the asterisk.

* Except in California

None of this can happen federally by edict. It's both the blessing and curse of a representative form of government that consensus is needed. Even if that consensus is just in selecting our individual representatives.

As you noted, it's a TANSTAAFL thing. Cut coal emissions to reduce certain pollutants by switching to natural gas. Increase CO2 by burning natural gas. Switch to electric vehicles but where will the electricity come from? Burning more natural gas? Nuclear? Not until that waste problem is figured out, I hope. Solar? How much pollution is created by the manufacture and disposal of solar panels? TANSTAAFL again.

Ohio decided to implement an annual $100 license plate surcharge on hybrid cars and an annual $200 license plate surcharge on electric cars. My hybrid got about 44 MPG, almost the same as my kid's 2006 Civic. I no longer own a hybrid because my driving is way down so high MPGs is no longer a real factor to me but it was costing me more, over two months of fill-ups, in license plate surcharges.

The real nonsense that needs stopped is this selling and buying of "carbon credits". When it's cheaper for a polluter to buy carbon credits than it is to literally clean up their act nothing will get cleaned up.

I am not so sure CO2 is as big of a concern as made out to be. Plants love CO2 and in appreciation of it they give us more O2 (which is very important to human life). Don't get me wrong, there are pollutants everywhere, alongside many roads, in the trash dumps, in the air, oceans, and a lot of our freshwater supplies, that all of mankind should stop and clean up but CO2 isn't a poison, and if you believe the science (as I do in this case), back when the planet was flourishing with plants, trees, and dinosaurs the CO2 was 4~5 times what it is today.

I haven't found a thread about this, but this is now our reality. I think our pre-def engines are the low hanging fruit of this new policy. Maybe the feds will offer us a cash for clunkers buyout to get these engines off the road.

At a minimum, they will prevent these old engines from using the interstate system.

I expect something to happen within 3 years.

Diesel engines produce less CO2 than gasoline engines so if the intention is to get rid of CO2 (a preposterous concept) then we should be banning gasoline engines. Pre-DEF diesel engines do however produce more nitrous oxides. This helps to create smog, and in certain large cities that sit in a valley with little wind, like LA or Mexico City, this can be a problem. It is generally not a problem outside of these cities, and the nitrous oxides actually provide a useful fertilizer for greening of the earth.

Me too, in fact researchers claim that the Earth's atmosphere is losing O2 at an ever increasing rate, so where and how can we get more O2? Plant life is the answer and the more CO2 the more plants.

It had been a good day! Did you have to post this so soon after lunch?

I can't count how many plants I've been to in the last five years that emit over 10 MILLION TONS of CO2 annually. One natural gas processing plant I was at earlier this month spit out 230 tons an hour from one stack. That wasn't a combustion process either, just CO2 stripped out of the inlet gas stream.

Your 700 mile journey calculations caught my eye. This is a legitimate question: How can a portion of the gaseous emissions (CO2) weigh more than the fuel itself? If this is Uncle Joe's math for all things green? If so, we are doomed for sure! That's pure magic if 700 pounds of diesel can produce 1000 pounds of CO2!

I think you're forgetting about the weight of the oxygen that the carbon takes on during the combustion process to produce CO2.

[TandW]

Maybe that explains why we lose weight during the night.

Exactly! Willliam Shakespere play, Henery VI, part 2, act IV, scene 2 quote " The first thing we should do; lets kill all the lawyers". Of course this was not a literal statement it was a play. https://www.forbes.com/sites/georgel...h=2c24d16d3d98

They even wrote a song about you: "Every breath you take"!

CO2 is a waste product of human cellular metabolism. Literally every breath you exhale has CO2 and the amount tells medical professionals how well you're breathing and exchanging oxygen in the lungs.

When your blood level of CO2 rises your body breathes faster to off-gas more CO2 and increase oxygen levels. The level of CO2 controls your breathing rate, not the level of oxygen.

This is why the low oxygen saturation levels seen in some COVID patients is so fascinating to me. The people are completely functional but the very high levels of CO2 should be driving their breathing distress though the roof. COVID must be messing with the blood CO2 receptors somehow but I've read very little on this.

Hey, maybe Mother Nature has COVID and that's why planetary levels of CO2 are rising.
