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.

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

What you are referring to sounds like Hypoxic Drive. Its common in COPD patients as well. Breathing reflex is driven by low o2 levels instead of elevated co2.

If you think the US is a major polluter watch "Dicing With Death" series on Prime. The average age of the world's vehicles is over 20 years old and has never been overhauled meaning excessive emissions.

Let's not worry too much about atmospheric CO2. It's required for photosynthesis and it is the basis of all life on earth. We could actually use a lot more of it as we are presently near the lower limit below which terrestrial life is unsustainable.

Ventilatory drive. A body at rest has lower drive. Thus the need for night-time oxygen in many COPD patients, like me. Or in sick people hovering in and out of consciousness.

One thing I've learned over the course of my 67 years on this rock is that politicians throw these ideas and wacky proposals out there in hopes some part of it will stick to the wall. The end result will be quite different from what is proposed. It is a negotiation starting point. It's how politics works.

I guess I am forgetting that, and I'm no scientist. Can't we look at the mass of Oxygen and call it a "good element" that was present naturally, and not count that portion as we try to get into these schemes of apportioning carbon credits and penalties?

1 volcano eruption spews more carbon into the atmosphere than most countries emit in 100 yrs.

Volcanos are an important part of the carbon cycle. There has to be a way to get carbon back into the atmosphere otherwise photosynthesis will stop and terrestrial life on earth will end. Atmospheric CO2 levels have been steadily declining over the millennia, so much so that during the last ice age they almost dropped to below the minimum necessary to avoid an extinction event. Today's CO2 levels are still dangerously low. It is a good thing that we are releasing some carbon back into the atmosphere by burning fossil fuels.

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.
And just how is the federal government going to do that and if they tried half the states, if not more, would instantly file legal briefings to prevent the federal over reach. The feds tried stupid stuff like this with water regulations which failed.

If we only had a well thought out, comprehensive plan instead of a shot gun approach like banning straws and shopping bags.

Why hasn't govt stepped up, lead the way and migrated their fleets to EV instead of mandating that we must do it?
Has anyone seen a study that determined how much extra elec generation will be needed and where, when it will come from?

Increasing the supply of electricity will come mainly from natural gas, but only if we allow fracking and construction of pipelines. Forget about windmills or solar. These are pipe dreams. Also forget about nuclear or hydroelectric. It is impossible to get a permit to build a nuclear reactor or a hydroelectric dam.

Isn't petroleum refining somewhat like the meat packing industry? That is one raw material goes in & many different products come out?

If petroleum fuels are less in demand we still need petrochemicals so to me the idea of eliminating oil drilling is short slighted.
