Researchers from NASA's Goddard Space Flight Centre, also the home of famous carbopocalypse doom-prophet James Hansen, have repeated earlier assertions that atmospheric soot may be as important as greenhouse gases in driving global warming.
This could be good news for humanity, as atmospheric soot levels would be much easier to reduce. Filtering soot out of exhausts from diesel engines and coal burners is simple compared to removing and sequestering CO2, and as an added benefit the effects would be rapid: soot doesn't persist in the atmosphere for long periods the way greenhouse gases do, as it is washed out by rain or snow. However, many environmental campaigners would resist the idea of soot taking centre stage, fearing that this could lead to a reduced emphasis on greenhouse-gas emissions reductions.
Ice running off the gutters of the 'roof of the world'.
Earlier investigations including the effect of soot had focused on the Arctic, where Goddard scientists have previously suggested that "the impact of aerosols is just as strong as that of the greenhouse gases". Aerosols include soot, which tends to heat the atmosphere, plus sulphates and others which cool it. Unfortunately sulphates also cause acid rain, and clean-air regs in the US and Europe have seen them massively reduced - and the Arctic warm up.

Mine also gets over 20 mpg at 75 mph. And there is NOTHING, and I mean NOTHING like the feel of over 1000 foot pounds of that massive and steady Diesel torque!
Shame on NASA.
The color of the smoke or the color of the truck? LOL
OK, I’m assuming that’s not a “stock” diesel. What kind of mods have you made?
I have a 2001 Excursion with the 7.3 Powerstroke and an older (2002) Superchips microtuner, but I can’t get near the 450 hp mark. But then again, with 212K miles on her, I don’t want to kill the transmission :)
Smoke em if ya got em....
The Alison has no problem what so ever of dropping that HP to the ground.
What the soot, carbon black, does in the air is not clear. Studies are still somewhat scattered in results since it also serves as a cloud progenitor. However, there is definite cause to believe that it increases albedo of the earth, making it slightly darker, when it comes back to the ground.
Only a 1% increase in the albedo of earth by whatever means easily accounts for all warming of the 20th Century.
I wouldn’t fight less soot-producing technologies, since it is a definite sign of incomplete combustion, and wasted energy. I want to see all of it become CO2 (fertilizer) in the atmosphere instead.
God forbid volcanic eruptions keep happening or the greens will never get the earth tidied up..
They really want to reduce soot because it will lead to global warming’s Second Coming followed by the Funding Rapture. Soot nucleotides induce thick cloud formation which cools the surface. They know that.
These SOB’s are relentless. They will get you from any conceivable angle.
LOL....The Greenies can’t keep their own nests tidy from what I know about them!
