Got me... I was going to ask, but decided against it.What's the significance?
After thinking about it I think he was trying to say there are stupid rednecks in the south bringing down the scores or something.What's the significance?
The significance is that when teaching a homogeneous population there are many common frames of reference, and thus less opportunity for miscommunication or misunderstanding during the teaching process. In a more diverse society, you'll have multiple languages, multiple dialects of the same language, even in the same locality, differing income levels, differing exposure to things in the world (i.e. a good many poor people may not take travel much or be exposed to things the middle class takes for granted), parents who may not take interest in their children's studies, etc.. Because of all these factors, teaching in a heterogeneous environment is much more difficult. I still think the schools could do better, but to some extent the deck is stacked against them. I also blame the teacher's unions for a lot of arcane work rules which work against the educational process.What's the significance?

Anyway, I don't know if anyone else has ever tried teaching, but it's part of what I do in life. It is very hard to teach in an environment with students from wildly different cultural and economic backgrounds. It's much easier if everyone is more or less on the same page
Once again, the underlying factor is population growth, that which fuels more of the world's problems than anything else.The burning or rotting of trees that comes with deforestation — at the hands of ranchers, farmers, timbermen — sends more heat-trapping carbon dioxide into the atmosphere than all the world's planes, trains, trucks and automobiles. Forest destruction accounts for about 20 percent of manmade emissions, second only to burning of fossil fuels for electricity and heat.
The latest data from the Food and Agriculture Organization (FAO) helped spur delegates to action.
"Deforestation continues at an alarming rate of about 13 million hectares (32 million acres) a year," the U.N. body said in its latest "State of the World's Forests" report.
Because northern forests remain essentially stable, that means 50,000 square miles of tropical forest are being cleared every 12 months — equivalent to one Mississippi or more than half a Britain. The lumber and fuelwood removed in the tropics alone would fill more than 1,000 Empire State Buildings, FAO figures show.
Although South America loses slightly more acreage than Africa, the rate of loss is higher here — almost 1 percent of African forests gone each year. In 2000-2005, the continent lost 10 million acres a year, including big chunks of forest in Sudan, Zambia and Tanzania, up from 9 million a decade earlier, the FAO reports.
Across the tropics the causes can be starkly different.
The Amazon and other South American forests are usually burned for cattle grazing or industrial-scale soybean farming. In Indonesia and elsewhere in southeast Asia, island forests are being cut or burned to make way for giant plantations of palm, whose oil is used in food processing, cosmetics and other products.
In Africa, by contrast, it's individuals hacking out plots for small-scale farming.
Here in Nigeria's southeastern Cross Rivers State, home to one of the largest remaining tropical forests in Africa, people from surrounding villages of huts and cement-block homes go to the forest each day to work their pineapple and cocoa farms. They see no other way of earning money to feed their families.
"The developed countries want us to keep the forests, since the air we breathe is for all of us, rich countries and poor countries," said Ogar Assam Effa, 54, a tree plantation director and member of the state conservation board.
"But we breathe the air, and our bellies are empty. Can air give you protein? Can air give you carbohydrates?" he asked. "It would be easy to convince people to stop clearing the forest if there was an alternative."
The state, which long ago banned industrial logging, is trying to offer alternatives.
LOL, I still get that spinning wheel when I hit the quick edit/save option...nothing happens, it's not my imagination , only way to edit now is to go to 'advanced edit' and then 'save changes', before the 5min time period expires.
The whole point of discussing the issue outside of mudslinging politics and mental masturbation is how does this information change the way I live my life.
In order to examine the issue and come to a final understanding we must answer some basic questions:
What is happening? Is the earth warming, cooling or something else?
Why?
What can we do about it?
Let's see if we can keep it civil and free from hyperbole. I present this article to start.

Dr. Kenneth Tapping is worried about the sun. Solar activity comes in regular cycles, but the latest one is refusing to start. Sunspots have all but vanished, and activity is suspiciously quiet. The last time this happened was 400 years ago -- and it signaled a solar event known as a "Maunder Minimum," along with the start of what we now call the "Little Ice Age."
Tapping, a solar researcher and project director for Canada's National Research Council, says it may be happening again. Overseeing a giant radio telescope he calls a "stethoscope for the sun," Tapping says, if the pattern doesn't change quickly, the earth is in for some very chilly weather.
During the Little Ice Age, global temperatures dropped sharply. New York Harbor froze hard enough to allow people to walk from Manhattan to Staten Island, and in Britain, people reported sighting eskimos paddling canoes off the coast. Glaciers in Norway grew up to 100 meters a year, destroying farms and villages.
But will it happen again?
In 2005, Russian astronomer Khabibullo Abdusamatov predicted the sun would soon peak, triggering a rapid decline in world temperatures. Only last month, the view was echoed by Dr. Oleg Sorokhtin, a fellow of the Russian Academy of Natural Sciences. who advised the world to "stock up on fur coats." Sorokhtin, who calls man's contribution to climate change "a drop in the bucket," predicts the solar minimum to occur by the year 2040, with icy weather lasting till 2100 or beyond.
Observational data seems to support the claims -- or doesn't contradict it, at least. According to data from Britain's Met Office, the earth has cooled very slightly since 1998. The Met Office says global warming "will pick up again shortly." Others aren't so sure.
Researcher Dr. Timothy Patterson, director of the Geoscience Center at Carleton University, shares the concern. Patterson is finding "excellent correlations" between solar fluctuations, a relationship that historically, he says doesn't exist between CO2 and past climate changes. According to Patterson. we shouldn't be surprised by a solar link. "The sun [is] the ultimate source of energy on this planet," he says.
Such research dates back to 1991, when the Danish Meteorological Institute released a study showing that world temperatures over the past several centuries correlated very closely with solar cycles. A 2004 study by the Max Planck Institute found a similar correlation, but concluded the timing was only coincidental, as the solar variance seemed too small to explain temperature changes.
However, researchers at DMI continued to work, eventually discovering what they believe to be the link. The key factor isn't changes in solar output, but rather changes in the sun's magnetosphere A stronger field shields the earth more from cosmic rays, which act as "seeds" for cloud formation. The result is less cloud cover, and a warming planet. When the field weakens, clouds increases, reflecting more light back to space, and the earth cools off.
Recently, lead researcher Henrik Svensmark was able to experimentally verify the link between cosmic rays and cloud formation, in a cloud chamber experiment called "SKY" at the Danish National Space Center. CERN plans a similar experiment this year.
Even NASA's Goddard Institute of Space Studies -- long the nation's most ardent champion of anthropogenic global warming -- is getting in on the act. Drew Shindell, a researcher at GISS, says there are some "interesting relationships we don't fully understand" between solar activity and climate.
cow methane, produce 143lbs/yr which has 23x warming potential compared to CO2!!!
PROTEST MAY BOOST COAL PRICES
Australian environmental activists will block world's largest coal port and rail line
A planned protest by up to 1,000 activists may disrupt coal prices from Australia’s Newcastle port, giving another boost to near record coal prices, which have already tripled in the past year.
Posted: Tuesday , 08 Jul 2008
CANBERRA (Reuters) -
Environmentalists plan to block one of two rail lines into Australia and the world's biggest coal export port at the weekend, they said on Tuesday, amid international wrangling over efforts to combat climate shift.
Any disruption to coal shipments from the Newcastle port could give another boost to benchmark coal prices that are already near record highs at nearly $195 a tonne, having more than trebled in a year. Up to 1,000 protesters are planning on Sunday to block the rail line into Newcastle port, north of Sydney. The export terminal plans to ship 95 million tonnes of coal over the next year.
"You could say it's drastic action but it's simply because these are drastic times. We need to actually start taking serious action," Friends of the Earth spokesman Cam Walker said.
Activists from a coalition of green groups would start a "camp for climate action" from Wednesday and planned to sit on one rail line into the port to halt coal trains travelling from the nearby Hunter Valley coal mining region, Walker said.
Smaller protests would also happen on Monday and could include more rail line sit-ins, as well as actions aimed at other port installations, another Friends spokesman, Damien Lawson, told Reuters.
With consistent demand, mainly from energy-hungry China, 38,679,777 tonnes of coal were exported from Newcastle in the first five months of 2008, versus 37,154,848 tonnes a year earlier, port data showed last week.
Coal exports from Newcastle port surged to 2.059 million tonnes last week, while queues for loading slightly eased to 38 ships. The port is aiming to cut the shipping queue to around 20 vessels before the end of September.
The Newcastle protest will follow the G8 meeting of rich nations in Japan, where leaders were on Tuesday were preparing to take an "important step" forward on fighting climate change after negotiators agreed on a joint summit statement.
The European Union has pressed the United States to go beyond a commitment at last year's summit in Germany to "seriously consider" carbon emissions cuts of 50 percent by 2050 by now agreeing to that target and the need for shorter-term action.
"We want to send a message to the G8 and to Australia's government following the recent Garnaut report (into climate change and emissions trading)," Lawson said. "Coal is a major cause of global warming."
Australia is the world's biggest coal exporter and the biggest per head producer of greenhouse gases, emitting five times more per person than China, due to use of coal for for almost 80 percent of the country's electricity.
Australia's net greenhouse emissions totalled 576 million tonnes of carbon dioxide equivalent, or about 1.5 percent of world emissions. (Reporting by Rob Taylor; Editing by Valerie Lee)
But everyone still needs to cut back on CO2 emissions even the people who are cooling right?No, it's global climate change. And your local climate will change, one way or another.
But everyone still needs to cut back on CO2 emissions even the people who are cooling right?
You clearly missed my point. The climate has been changing for longer than we've been around. The earth has warmed and cooled, many times. In fact the climate has always been changing. It never is a constant. The climate changes on cycles. We haven't been around long enough to know where we are on the cycle. To assume that we humans are responsible for the climate changing is nothing but sheer arrogance are the part of some people. These people are then being used by other people who use environmentalism as a front for pushing a particular political agenda.No, I just don't believe that an intelligent person still doesn't understand the concepts behind climate change. This only leaves 2 options, and I'm assuming you are intelligent. The alternative would be that you are intentionally taking a false stand for some other reason. Trolling would be the most likely.
Nuclear fission is the best bet for now, nuclear fusion perhaps 50 years from now. Solar and wind can certainly find a lot of niches where they would work also but they'll never supply more than 25% of our power combined (and that's an optimistic estimate). Geothermal and tidal are a few more, again good mostly for niche uses.I'm all for using non fossil fuels. Call me when we find one that's actually viable. Ethanol from corn sure isn't.
I don't disagree with any of them. I just haven't seen any proof that the sum of them ads up to a statistically significant component in climate change. Correlation does not equal causation.
CO2 is only ~385PPM (by volume) in our atmosphere. On Mars the atmosphere is nearly 95% CO2, yet Mars is very cold. Clearly CO2 concentration is not the only factor in the climate.
Yes, I realize that. I was attempting to illustrated the absurdity of focusing only on one characteristic and making it the sole focus.You also have to consider that Mars is 37 million miles further from the sun compared to earth. That could affect how CO2 plays with the temperature even if it's 95% of the atmosphere.
Yes, I realize that. I was attempting to illustrated the absurdity of focusing only on one characteristic and making it the sole focus.
Focusing on elements that we can't control (like our distance from the sun) is a waste of time.
