This is a huge win for sanity. In the USA at least, the removal of the greenhouse gas endangerment rules has to allow mariners to return to sensible propulsion and be a guide for other nations and recalcitrant international bodies to follow suit. Oh, and rev up your V8 muscle car and smugly grin as you wave at stranded or burning EVs. > **[Skeptics Win, Endangerment Finding Axed – Truth Finally Prevails in The...](https://wattsupwiththat.com/2025/07/29/skeptics-win-endangerment-finding-axed-truth-finally-prevails-in-the-climate-wars/)** > > None of this would have been possible without those who dared to speak up and challenge the narrative, often at great personal and professional cost. > **[EPA Chief Lee Zeldin to Repeal Obama' $1 Trillion Green-Reg Machine, "Most...](https://gellerreport.com/2025/08/epa-chief-lee-zeldin-to-repeal-obama-1-trillion-green-reg-machine-most-significant-deregulatory-action-in-u-s-history.html/?lctg=81798971)** > > Unleashing America!

Why stop there? Leaded high-octane gasoline was way cheaper than the modern alternatives, we should bring that too. After all, nobody died _immediately_ of lead poisoning! ---

Why stop there? Lots more sacred cows to slaughter. But this one is just starting the ball rolling. Good to see everyone agrees a $1 trillion handicap on the US economy is not just small change. Fortunately the EPA didn’t have to rescind any restrictions on the most significant so-called greenhouse gas. The stuff is absolutely everywhere. ---

Remember when NOAA and NASA proved the reduced sulfur fuels caused “dramatic unintended consequences” “rapidly increasing ocean temperatures”? Just the invention of the mini split AC system will release more refrigerant into the atmosphere than ever and will never be overcome. Every shack world wide has a $300 mini split. Do you think they recover anything? Every auto parts store in the world sells refrigerant now. Your EPA certificate is worthless. China builds 2 massive coal powered power plants a week. It is one atmosphere for the geniuses that think the US can change it. Working for MAERSK there is no way to land recovered refrigerant. I raised hell for years. They do not land any for their fleet. What do you think they do? I store it until ships go to scrap. As this is under engineering, do some research. Large world wide solar farms have radiated massive amounts of heat into the atmosphere. That alone has raised the temperature of the atmosphere 1 deg C. Heat domes are created by paving over paradise. Do you think they are going to stop building? Let’s see if you can read some global climate studies, NOAA studies, and look at NASA thermal imagery and reports. It is a money making scam. Get over the BS climatologist. After all they proved they are causing the warming. Plant trees! Look up what they do! While your reading the reports and seeing what trees do go back and read some chemistry.

> [@Kingrobby](#): > > Wow, those websites the articles came from are laughable, hot trash. So produce your own. Why doesn’t the rabid Lefty communist media even mention it? Any argument with the fact that the endangerment finding is on its way out and that this removes government overreach by a huge amount? I think this decision is commendable. Say something about the decision. ---

If one followed all that money planned for ‘confiscation’ from greenhouse gas emissions you’d find it mostly goes to Brussels and fuels media, public opinion, protests and all the rot that robs the ‘people’ of advancement. ---

I remember in the 1960s when you could smell Singapore before you could see it, no matter where you approached from. That hasn’t been the case since the early 1970s. That shows that it is possible to solve a long standing problem, if you use the right balance of “slick and carrot” PS\> LKY started the “Keep Singapore Clean” campaign in 1968: [https://www.nlb.gov.sg/main/article-detail?cmsuuid=b2c2c063-431a-4aa3-8c8d-02dc3b2a117d](https://www.nlb.gov.sg/main/article-detail?cmsuuid=b2c2c063-431a-4aa3-8c8d-02dc3b2a117d) ---

Air pollution is a whole other story than drainage sewerage and garbage collection, all done well in SG. As a major refiner, port and airport SG probably pollutes more than most LA like Melbourne (OZ) has cold inversion layer to lock in the pollution so people are aware, every other city gets away with it. USA did a great job with cars to clean up LA air which caused the world to follow, eventually. I remember flying in out LA SF and flying through the orange layer then smell it in the plane. Go out on clear bright day and not be able to work out where the sun is, yuk. Can see it in 80’s movies. ---

Can I simply remind everyone that CO2 is NOT pollution. The main GHG, water vapour, is not pollution either but the eco-zealots haven’t worked out how to ban it without looking utterly stupid so they shut up about it altogether.
