The Biggest Science Story of the Week

newtboy says...

*doublepromote someone else finally noticing global dimming as a significant factor in global warming.

Global dimming from excess sulfur dioxide may be responsible for cutting the current excess anthropogenic heat in the system by between 15% to 50% depending on the study.

What this means is, if we stop polluting tomorrow, the CO2 and other greenhouse gases will continue to warm us at the same rate for decades to centuries, but the sulfur dioxide that has blocked between .25 to 2 degrees Celsius temperature rise will be gone almost immediately, and a significant sudden rise in temp will be the result kicking off or feeding more feedback loops.

While it may seem he’s onto some global warming solution…just put more sulfur dioxide into the atmosphere…that ignores the lower growth rates and lost solar production it causes by deflecting a significant percentage of sunlight, both adding to net CO2 added to the system.
The incredibly scary part is the whitehouse and other international governments are actively researching ways to inject sulfur dioxide into the upper atmosphere despite knowing it has so many issues.

There’s no easy fix.

World's Most Dangerous Job

Idiot narrator/narration. The gases discharged there are dominantly sulfur dioxide - not hydrogen sulfide. There is a difference - and each has a different physiologic impact on human health. Clearly these people are being impacted by the sulfur dioxide...
These so-called science videos should really try harder to get their science correct.

RNC declares that coal is Clean

newtboy says...

What's hilariously terrible is, the 'dirty smoke' that coal use produces is the only mitigating factor of coals environmental destruction. The sulfur dioxide it produces goes into the upper atmosphere and reflects sunlight, actually COOLING the atmosphere. IF they ever actually perfected "clean coal" technology, it would be more damaging to the planet than "dirty coal" is, because at least dirty coal produces global dimming effects that have mitigated as much as 1/2 of the temperature rise due to excess CO2. Without that dimming, we'll suddenly see a HUGE rise in temperatures worldwide, and all the associated damage.

Sulphuric Acid - This is why you don't want to mess with it

I don't know. We know global warming is real, but no one can accurately say it's man made. Over 95% of the carbon emissions are naturally made, the majority of emissions coming from volcanoes. These things were around long before the industrial age, and life on earth seems to have evolved just fine. We also know our earth has experienced global warming in the past, so this may be a cyclical event man has no influence over.

You really should read more about what climate scientists who study this say. For one, the massive climate changes in the past coincide with mass extinctions. For another, study of how the environment responds to differing levels of CO2 shows that small changes in total CO2 output can cause significant changes in climate (as in, the kind that causes mass extinctions). Then there's also the whole idea of multipliers, where small warming causes a change like the melting of permafrost, which makes that part of the earth less reflective (and also amounts to a change in climate).

In the 70s "they" said we were facing an ice age. Did we? Remember acid rain? Another 70s scare that turned out to be a red herring for environmentalists. Good science always prevails, and there's probably a good reason why Al Gore is being sued for fraud.

Did "they" say that? From what I've read on the supposed new ice age, there was a small minority scientists who said that, and the media amplified it completely out of proportion.

It's funny that you bring up acid rain though. You know why that went away? We implemented cap and trade for sulfur dioxide emissions, and it essentially eradicated the problem.

As for the "good reason" Al Gore is being sued for fraud, it's because there's a tremendous amount of right-wing political groups and corporations that want to discredit the entire environmental movement. A cost-effective way to do that is to try to tarnish the movement's most recognizable representative.

I can give you the Libertarian perspective: you solve it with lawsuits. If you pollute and it affects the health of others, then they have a right to sue for damages. There's no corporation limit to liability in a free market, and class actions would prove to be silly. People individually would sue the company and that would deter them from damaging the environment.

Ahh, so that's how you completely disguise all responsibility. If I get killed in a road accident during a freak snowstorm caused by global warming, mintbbb has to choose between using the life insurance money to settle affairs and pay off debts she may not be able to service without my income, or gamble it by trying to engage in a lawsuit against a coalition of oil, gas, coal, and power companies?

If we were talking about someone pissing in my water supply, would I really have to drink it, and then later prove beyond a shadow of a doubt that it did some harm to me before I could expect law enforcement to get involved? Couldn't I just say "I don't consent to have pee put in my drinking water!" and get the police to stop people who wouldn't comply?

Psychologic says...

^ I'm not sure what they are measuring. A quick search resulted in some air pollution numbers from 2000, but the US's portion of the world's output was a little below 45%.

Carbon Monoxide: 13.86%
Sulfur Dioxide: 8.41%
Nitrogen Oxide: 6.52%
Non-methane VOC: 9.78%

Maybe they meant 45% of the total released from all vehicles worldwide? That's the best I can think of.

What the fuck people? This is the Internet! You're not allowed to have better-halves, spouses, partners, occasional circle jerks, rolling blackouts, tree hugging marathons, gestational periods lasting longer than seven years, green furnaces covered in spruce tree sap, Oingo Boingo ticket stubs from 1984, barbecue-flavored popsicles, blankfist's herpes, sulfur dioxide crystals, porcupine shavings, weapons of mass construction, sanitary napkins shaped like Paul Anka's flaccid penis, mummified chickens, ancient Aztec secrets of pubic hair grooming styles, Bono, testicular fortitude, or lovers!

All your relationship are belong to me!
