Have we been doing it wrong? High rpm's bad when not needed?

But you can't spend trillions and vilify your opponents unless it's "their fault" and you are the "savior" who requires more power to save them.

I don't buy the human GHG causing climate change idea. But soot is harmful to breathe, and it can travel a very long way before it drops to the ground. I am talking about more than 1000 miles. That is why cities get foggy from emissions and smoke from forest fires makes the sky hazy several states away from the fire. But rural diesel emissions are a very small part of that, especially if they are properly tuned.

But statically, people in cities (who are breathing in lots of diesel particles, from busses and heavy traffic) live longer… go figure
Now there’s all these new studies showing particles from tires and brakes wearing , are more numerous and terrible for you and the environment, along with silicon dust from county back roads.

I did not know that city people lived longer; it was surprising to me. I found the below article link, which suggests that access to health care, a higher % who smoke, and more obese people may be responsible. I certainly do not think urban air pollution helps longevity!

Life Expectancy Gap Between City And Country Folk Widens: How Access To Health Care Plays A Part

The last 40 years has seen a widening gap between urban and rural dwellers with regard to life expectancy, which experts attribute to access to health care services, smoking and geographical shift in resources.

It would certainly feel like it, I couldn't stand living in a city.
Hell I don't even want to live within a Village limits.

There has been much published about this. A small sample: NASA Astrobiology

Not sure we're reading the same article.

The one you linked mentions that no doubt Mars has undergone large-scale climate change in the past, that it *may* be undergoing climate change currently (unsurprising that some change occurs, but there's no mention of magnitutde) and it also mentions seasonal climate change.

There's no comparison with what's going on on Earth.

I suggest continuing your research. I don't have time for it. But here is an interesting graph that puts Earth's climate into perspective. We will eventually go into another ice age. We can adapt to whatever the current climate changes are.
