Ideas for both negatives and AFF to research


I didn't know exactly what you meant mr e. about posting this in a forum so i just made this i guess. Here debators will collect all their information and share it with others to build stronger cases when the next tournament starts.

The first topic that i have found is called geosequestration.


i found this in a cnn article:

CANBERRA, Australia (AP) -- Australia has begun pumping carbon dioxide underground to reduce greenhouse gas emissions, using a technology that locks dangerous gases deep in the Earth.

Geosequestration has the potential to significantly reduce greenhouse gas emissions from the burning of fossil fuels.

Officials opened a plant in southern Victoria state on Wednesday that they said would capture and compress 110,231 tons of carbon dioxide from industry emissions and then inject it 6,500 feet underground into a depleted natural gas reservoir.
The research and demonstration project has been developed with federal and state government support.
Australia is one of only a handful of places that uses the technology, known as geosequestration, and environmentalists immediately criticized the project as a token gesture that distracts from the bigger goal of getting industry to slash emissions.
The minority Greens political party said the project would achieve little and should be abandoned in favor of plans that would achieve much bigger emission cuts.


The project "is government-funded PR for the coal sector and would be a perfect place to start for a government looking to find budget cuts," Green Party Sen. Christine Milne said.
Officials said scientists at the site would monitor the reservoir to measure gas leaks and other factors, with the ultimate aim of demonstrating that geosequestration is a safe, viable way to combat global warming on a large scale.
"The project has a very important role in demonstrating the technical and environmental feasibility of geosequestration to Australia and the world and preparing the way for its widespread application," Peter Cook, the project's chief executive, said in a statement.
The technology is similar to that used at about 144 sites in the United States, where carbon dioxide is injected underground to help recover oil reserves.
Since 1996, 1.1 million tons of carbon dioxide a year have been injected under the Sleiper oil field in the North Sea and about the same amount under Algeria's In Salah gas fields in the past two years.

Getting dirty with black carbon
Posted: 02:26 PM ET

Climate change discussions often focus on carbon dioxide, but another major culprit gets unleashed every time a truck drives on diesel fuel.

Black carbon, a principle component of soot, contributes more to climate change than previously thought, new research shows. In fact, black carbon could have as much as 60 percent of the current global warming effect of carbon dioxide, scientists reported in the journal Nature Geoscience.

Diesel combustion in trucks, buses and cars emit a lot of black carbon. The particulate air pollution also commonly comes from burning firewood, indoor cooking, and biomass burning.

Using data from satellites, aircraft and surface instruments, the scientists found that the warming effect of black carbon amounts to 0.9 watts per meter squared. Thats at least two times greater than estimates put forth by the United Nations-sponsored Intergovernmental Panel on Climate Change (IPCC), the researchers said.

Besides making things look dirty, black carbon particles contribute to the retreat of glaciers and pose a public health risk, said V. Ramanathan, co-author of the study and atmospheric scientist at the Scripps Institution of Oceanography at the University of California, San Diego.

A major difference between black carbon and carbon dioxide is in their respective life spans, Ramanathan said. Carbon dioxide molecules can stay in the atmosphere for more than 100 years after being released, whereas black carbon only stays up there for about 10 days.

Black carbon pollution is a problem worldwide, the scientists said. China and India are responsible for between 25 and 35 percent of black carbon in the global atmosphere, mostly from burning wood and cow dung for cooking and using coal for heating. Countries that extensively use diesel fuel for transportation are also responsible for a lot of black carbon pollution.

While policy action should be taken to reduce black carbon emissions, it would be a catastrophic mistake to think thats enough, without also addressing the problem of carbon dioxide emissions, Ramanathan said. We have to do both, he said.

This article i found mostly from looking at the rising food prices. but i found something on next years topic and ethanol so read the entire thing because it seems interesting. If you don't want to read the whole thing than just scroll down to the red letters.

(CNN) -- Riots from Haiti to Bangladesh to Egypt over the soaring costs of basic foods have brought the issue to a boiling point and catapulted it to the forefront of the world's attention, the head of an agency focused on global development said Monday.

"This is the world's big story," said Jeffrey Sachs, director of Columbia University's Earth Institute.
"The finance ministers were in shock, almost in panic this weekend," he said on CNN's "American Morning," in a reference to top economic officials who gathered in Washington. "There are riots all over the world in the poor countries ... and, of course, our own poor are feeling it in the United States."
World Bank President Robert Zoellick has said the surging costs could mean "seven lost years" in the fight against worldwide poverty.
"While many are worrying about filling their gas tanks, many others around the world are struggling to fill their stomachs, and it is getting more and more difficult every day," Zoellick said late last week in a speech opening meetings with finance ministers.
"The international community must fill the at least $500 million food gap identified by the U.N.'s World Food Programme to meet emergency needs," he said. "Governments should be able to come up with this assistance and come up with it now."
The White House announced Monday evening that an estimated $200 million in emergency food aid would be made available through the U.S. Agency for International Development.
"This additional food aid will address the impact of rising commodity prices on U.S. emergency food aid programs, and be used to meet unanticipated food aid needs in Africa and elsewhere," the White House said in a news release.

"In just two months," Zoellick said in his speech, "rice prices have skyrocketed to near historical levels, rising by around 75 percent globally and more in some markets, with more likely to come. In Bangladesh, a 2-kilogram bag of rice ... now consumes about half of the daily income of a poor family."
The price of wheat has jumped 120 percent in the past year, he said -- meaning that the price of a loaf of bread has more than doubled in places where the poor spend as much as 75 percent of their income on food.
"This is not just about meals forgone today or about increasing social unrest. This is about lost learning potential for children and adults in the future, stunted intellectual and physical growth," Zoellick said.
Dominique Strauss-Kahn, managing director of the International Monetary Fund, also spoke at the joint IMF-World Bank spring meeting.
"If food prices go on as they are today, then the consequences on the population in a large set of countries ... will be terrible," he said.
He added that "disruptions may occur in the economic environment ... so that at the end of the day most governments, having done well during the last five or 10 years, will see what they have done totally destroyed, and their legitimacy facing the population destroyed also."

The World Bank announced a $10 million grant from the United States for Haiti to help the government assist poor families.
In Egypt, rioters have burned cars and destroyed windows of numerous buildings as police in riot gear have tried to quell protests.
Images from Bangladesh and Mozambique tell a similar story.
In the United States and other Western nations, more and more poor families are feeling the pinch. In recent days, presidential candidates have paid increasing attention to the cost of food, often citing it on the stump.

The issue is also fueling a rising debate over how much the rising prices can be blamed on ethanol production. The basic argument is that because ethanol comes from corn, the push to replace some traditional fuels with ethanol has created a new demand for corn that has thrown off world food prices.

Jean Ziegler, U.N. special rapporteur on the right to food, has called using food crops to create ethanol "a crime against humanity."

"We've been putting our food into the gas tank -- this corn-to-ethanol subsidy which our government is doing really makes little sense," said Columbia University's Sachs.

Former President Clinton, at a campaign stop for his wife in Pennsylvania over the weekend, said, "Corn is the single most inefficient way to produce ethanol because it uses a lot of energy and because it drives up the price of food."

Some environmental groups reject the focus on ethanol in examining food prices.

"The contrived food vs. fuel debate has reared its ugly head once again," the Renewable Fuels Association says on its Web site, adding that "numerous statistical analyses have demonstrated that the price of oil -- not corn prices or ethanol production -- has the greatest impact on consumer food prices because it is integral to virtually every phase of food production, from processing to packaging to transportation."
Analysts agree the cost of fuel is among the reasons for the skyrocketing prices.
Another major reason is rising demand, particularly in places in the midst of a population boom, such as China and India.
Also, said Sachs, "climate shocks" are damaging food supply in parts of the world. "You add it all together: Demand is soaring, supply has been cut back, food has been diverted into the gas tank. It's added up to a price explosion." E-mail to a friend E-mail to a friend

This is a restrictive definition of alternative energy for negatives when it comes to AFF plans. In other words, it helps better argue topicality and it also has a good source.

Alternative energy = energy from moving water, wind, the sun and gas from animal waste (from the U.S. Department of Energy webpage titled alternative energy.)
