Aerosols......from burning coal (according to this site) - COOL the planet.....

So, is it possible that the reduction of coal-fired plants has actually CAUSED warming?

1/2 of the Earth's surface is plowed and paved? Seriously?

So, ozone and aerosol coal-burning actually helps keep the planet cool?


the ONLY thing hurting us is burning oil and cow farts?

No. Aerosols do have a cooling effect and coal fired power plants do indeed generate aerosol pollution. You know what else they generate? Crap tons of CO2.

So the question then becomes, which forcing is stronger? Anthropogenic aerosol emissions or anthropogenic GHG emissions? The answer is one we have known well over half a century. Remember when we discussed the Rasool and Schneider (1972) paper in the other thread?

All anthropogenic forcings, whether warming or cooling, must be considered. When they are, the net effect is one of warming.

That's a silly claim. Who made it?

Burning coal warms the planet. When all associated forcings from coal burning are considered the result is one of warming.

On the cow farts, you're acting as if it's a reductio ad absurdum. It's not. Industrial farming of ruminants actually generates a lot of methane.

So does the California gas leak. I bet its making bovine flatulence pale in comparison.

They've thankfully plugged it.

Let's do the math though. The leak averaged about 1200 metric tons per day. Ruminant methane emissions account for anywhere from 76-92 million metric tons per year. Cows at their lowest estimate account for about 208000 metric tons per day.

of course, the aubie is an expert on cow farts ;)

Good thing we wiped out the buffalo....that would only have made things worse.

Maybe we can find a way to hook a hose up to cows and capture the methane and power houses and electric cars.

Not necessarily. A lot of it has to do with sheer numbers and how we feed them. In industrial farming, cows are generally fed a low nutrient fast growing ryesgrass, which causes excess methane as a product of digestion.

That, and there are far more domestic cattle than there ever were buffalo. There were at most 60,000,000 buffalo. Compare that to the 1,300,000,000 to 1,500,000,000 domestic cows alive today.

Not sure the cows would appreciate anyone trying that. I nominate you.

As of Jan 1, the number of cattle in the United States was 92 million
