It's effect is only on the numbers at a small level, but would not adversely effect the hypothesis (if it even would, there's many different models and just because there's a chance of this doesn't mean it's even part of a standard).

Nowa posted:Is there any truth to the theory that a reduction in greenhouse gas emissions will actually INCREASE the rate at which temperature is increasing? (Simply due to the soot and other particles in the air that are actually reflecting the sun's heat.) Yes. This has applications in things like "clean coal." You see, they leave all the invisible garbage in it (the stuff that is actually greenhouse gases), and take out the "gross" stuff you can see and filter easily, like soot and aerosols. The problem is that the latter, though nasty in your lungs, reflects certain wavelengths of the sun's radiation from even reaching us here on the surface when it is in the atmosphere. Greenhouse gases do not reflect the sun's radiation from entering, but do prevent the longwave radiation emitted from the heated Earth from escaping into space (this is due to the shape of the molecules involved). As a result you have a situation with more of the sun's radiation reaching the surface, but no more of it escaping into space than previously. EDIT: This is called the "aerosol effect" and actually contributed to a temporary global-cooling period around WWII due to the large-scale switch to burning oil, which releases a lot more aerosols. pwnyXpress fucked around with this message at 09:26 on Feb 23, 2012 |

A local council in Australia recently banned the use of non-degradable bags at supermarkets. Obviously it's not a fantastic solution since it'll still take time for the bag to degrade and there's plenty of other non-degradable plastics out there, but it's leagues better than continually contributing to the huge rubbish dump of plastic already out in the ocean. It's pretty unlikely anybody is on the level of evil as the villains in Captain Planet and litters while cackling evilly, saying 'haha, take that, environment!'. That said, encouraging/legislating for the use of bioplastics that degrade by themselves would reduce any further additions to the problem.

Since carbon dioxide + h20 <=> carbonic acid + heat, won't increased carbon levels in the ocean result in a temporarily decreased PH, then an increased PH, due to global warming heating the water and thus pushing the equation back towards co2 and water? If this is true, doesn't it mean that fish will get hosed over by the increased temperature and not the PH, and the ocean life that relies on CaCO3 to make shells will be hosed over due to CaCO3 being dissolved due to the new lack of carbonate ions in the water? I always understood it as being that it would be an increased acidity that kills everything but I've recently learned about chemical equilibrium and I think I might be wrong.

Global warming is a problem because of broad ecological effects; the actual heat increase is small enough that it won't have any harmful direct consequences. The pH of water is not appreciably higher if you warm it up a few degrees.

I know very little about ocean acidification, but according to this: quote:During the Pliocene warm period, about 3 million years ago, atmospheric CO2 was about the same as today, but pH was only 0.06 to 0.11 units lower than preindustrial conditions. This is because the event played out over 320,000 years or so. We see species migration in the fossil record in response to the warming planet, but not ill effects on calcifiers. This is because ocean acidification depends primarily on the rate of atmospheric CO2 increases, not the absolute concentration. So there's more going on than just a concentration-dependent equilibrium process.

You are right about a decrease in carbonate ions being the primary concern relating to ocean acidification, but I'm not sure what you are saying about how this relates to temperature. How else would fish be hosed by ocean acidification, besides having their calcifying prey obliterated? I guess it might be comforting that the decreasing solubility of CO2 in a warming ocean could limit how bad acidification can get. Too bad that that happens to be yet another positive feedback system: Less CO2 dissolving in the ocean means more CO2 in the atmosphere. Amarkov temperature often has really big ecological effects, especially in aquatic environments. Unusually high water temperatures are probably the biggest cause of coral bleaching around. Even without acidification threatening corals the heat stress alone is threatening to destroy many reefs. Warmer water also holds less oxygen, which causes plenty of its own problems.

Part of India's problem is it shares the same water source as Pakistan: glacier melt. Unfortunately, the glaciers are starting to disappear (the floods in Pakistan are another by-product of this). So India's agriculture will be doing just great. Until the glaciers melt and the water starts disappearing, and both countries start taking more than the share of water they've been allocated in their treaties.

It's not the sole source of water for India but many of its biggest and most important rivers originate in the Himalayas where they are fed by melting snow pack. The Ganges, Indus and Brahmaputra, rivers also important for Pakistan and Bangladesh, are all fed by snow and glacial melt. Sorry I don't have any data on what percent of their flow comes from melt water but I imagine it becomes important during the dry season.

The glaciers act much like natural reservoirs for the seasonal rains if/when the go, there is a serious issue with being able to have a stable access to water during the dry season, from September to June. The groundwater is being drawn down faster than it is replenished, much like how the U.S. is doing in the western states. India could draw more water from their rivers than the western U.S., but their surface water has some serious pollution issues.

This is the defining moment." - Dr. Rajendra Pachauri, IPCC 2007 I listened to a lecture by a longtime environmental activist by the name of Derrick Jensen. Over the years, he's watched progress turn backward, and he knows there's really no more time. He asked lots of rhetorical questions, and made the audience think deep about just how far they were willing to go to save their species. Jensen made it clear he did very little moral hand-wringing about the question, and that he would trade his life in defense of his home (earth) without a second thought. He said that when old action groups begin to reactivate and new ones form, it was not the duty of environmentalists to join them, or even support them; just to refrain from condemning them as they went about their work. The point is that the Keystone XL is like a no-brainer if you're an environmental insurgent. I think you'd have groups from all over the world gunning for it, and I simply don't see it getting built. They can't possibly guard the whole thing and it's too easy to put a hole in. Listening to somebody mention the possibility in public without fear gave me hope, and there are still far too many people who give a poo poo to start despairing just yet.

I'm of the opinion that regardless of the environmental consequences, nearly every barrel of economically-recoverable oil in the world will eventually be drilled, refined, and burned. Without some miracle tech that can let us live our current lifestyle without fossil fuels, people will simply not be willing to give it up. I'm just praying that either climate change turns out to be less severe than predicted, or we come up with some ingenious geoengineering scheme that doesn't kill us all. Because asking people to stop drilling is like asking hunters in 1875 not to shoot Passenger Pigeons. It's too easy, it's too lucrative, and while we probably could stop ourselves, we won't.

By the way, I'm not convinced that there will be a catastrophic, civilization-ending collapse. But if it does happen, I see no reason to think people would suddenly start living sustainably.

Yep, the precious first world lifestyles of Australia, America and the like we're built on the assumption of indefinite cheap transportation. The long expanses of suburbia become much less sustainable once you remove that assumption. How much rare metal is required to build the batteries to switch the entire first world over to electric cars? How much of that electricity is fossil fuel based anyway? How much of our oil based economy will electricity NOT be able to support using present tech, ie Agriculture, Heavy Transport, Mining? I don't know the answers to these, but it probably won't look like just a quick techno fix I'm sure. The electric car will not solve our problems, merely one of them, and a pretty small one at that, whilst a bigger one, namely that our cities are so poorly designed that there is an excessive amount of wasted resources in day to day living, goes unaddressed because it's such a difficult question to answer.
