Global Warning?- Should we be alarmed?

Question

Hi
Well I have this project for school and I want to know the most I can about global warming.
I have to tell my teacher that we should be alarmed over global warming,.
And I'm going to have a debate with another student.
so I have to have really good points for this.
Please help me, I really need this.
Thank You!

Answer 1

Yea, we're all doomed. Time to raise our arms above our hears, start screaming, and running around in shear panic.

Answer 2

Well I do not think there is cause for alarm.

But since you need arguments saying there IS cause for alarm, take a look at the CO2 graph in the source. Notice how much CO2 has gone up already. And notice how it is going up even faster now than just a few years ago. At the rate we are going, with China and India developing rapidly, it is going to go up and up faster and faster every year. CO2 is only one of the greenhouse gasses that cause the planet to be warmer than it would otherwise be, but it is the only one going up and up faster and faster. Surely this cannot go on forever! Look how unnatural the increase in the past 200 years looks compared to the natural variations from the last 400,000 years. Isn't that alarming?

Answer 3

Easy one...

The sun is hotter than its been in 1000 years. SO of course the temps will be warmer. Every planet in the solar system is 'suffering' from global warming. The idea that man can cause climate change is only in the Scifi realm. We are currently spending $5 billion a year and no one.... REPEAT NO ONE, has come up with one piece of proof that shows man's connection to global warming.

By the way, the UN expert.... Mert, was the formal minister of housing from the Netherlands. WOW some climate expert.

Answer 4

in your debate mention that the earth has natural cycles as well as natural cataclysms that have major effects on climate. then state that there are only three types of natural pollution which are: Volcanos, Forest fires, and impacts from space. throughout the entire life of the earth (before primitive man) this was the only source of co2, and other pollution. these natural phenomena happen intermittently throughout the ages causing the changes in climate, for example the ice ages. (there have been many ice ages)
ok so just think for the 4 billion years the planet has been spinning there have been huge fires, mega eruptions, impacts from space, lighning, etc. this caused an amount of co2 and methane and a whole slew of other pollutants into the air, naturally.
this continues for billions of years... untill the very first day that a primitive man wielded and controlled fire.

Ever since that fateful day some 400,000 years ago, there has been a fire (multiple multiple fires) burning in some form every second of every day of every year.... for 400,000 years.

now the earth has a fourth contributor to the natural pollutants caused by fire, eruption and impact: MAN

fast forward to the industrial revolution where we pump and continue to pump this very second billions of tons of pollutants into the air daily, from our homes, factories, buildings, power plants, wars, nukes, space shuttles etc etc. all of this in ON top of all the natural contributors that still occur in thier natural cycles, like volcanos, forrest fires, and impacts from space. making the co2 and other pollutants far higher than normal, far higher than natural and of course in a record blistering time span, that completely overrides and overloads the natural cycles, which without man... would take care of teh co2 and pollutants. The earth is trying as hard as it can, but there is jsut too much to deal with naturally, so now it is up to us, we put it there it is our job and our responsibility to remove it.

So. for the last 400,000 years we have been adding little by little more co2 than would naturally be there. period. its a fact, humans burn things, we are the only species on the planet to ever do it and now we are paying for it.

It is just that simple, it is just that clear, it is impossible to argue against, and if you use this in your debate you will win

good luck

Answer 5

It seems greater like a return of an Ice Age to me than to worldwide Warming. yet what I even have heard approximately it is that there will be warmer summers and chillier winters. In eire, the summer season are no warmer than earlier, however the iciness are fairly freezing recently! examine this internet site for greater techniques. study after replace 2: (a million) Now the rationalization why we've had 2 freezing winters final years and this one, is by using the fact the volcanic eruption of Iceland. Now, you probable won't have faith me. yet I study "Volcanology for Dummies" final year and located this passage the place they have been explaining that the sulfur dioxide which converts to sulfate aerosol reduces the incoming of photograph voltaic radiation by potential of backscattering it to area. by way of fact of this why the climate turns into chillier, plenty chillier. in actuality interior the 1816 after an eruption, there exchange into snow during the summer season in Northern Europe, Northeast US and Canada. consumer-friendly worldwide temperatures decreased approximately 0.4–0.7 °C (0.7–a million.3 °F), sufficient to reason important agricultural issues world extensive. Beside, in France and someplace else in Europe interestingly, in 1986 and 1987 the individuals suffered from 2 horrific winters (minus 25 ranges Celsius the 1st iciness, and minus 27 ranges Celsius the 2nd year). So there have been 2 winters in a row. Then, the iciness stabilized as quickly as greater. This photograph exchange into taken in 1987(2) yet while those winters save on, there must be somewhat fact with regard to the potential for a climate shift or a minimum of of a return of an Ice Age. enable us to desire, it is the final iciness to be so chilly. For the hypothesis of international Warming, examine this talk board: (3)

Answer 6

The earth is going thru a warming trend. It's done it before, and it will do it again at some time. Man hasn't caused it, and man can't fix it. There's nothing to be alarmed about. If anyone tells you different, their lying to you. Good Luck

Answer 7

Also with the ozone decreasing the UV rays can just sink right into the glaciers melting the water while the temperature goes up by .00000000001 so the scientists can tell you that we are going to die. My advice is to hang up all of your clothes to dry that way evaporation will cool the earth and you won't be using fossil fuels.

Answer 8

By ARTHUR MAX, Associated Press Writer 1 hour, 27 minutes ago (it is now Nov 17 22:27)

VALENCIA, Spain - Global warming is "unequivocal" and carbon dioxide already in the atmosphere commits the world to sea levels rising an average of up to 4.6 feet, the world's top climate experts warned Saturday in their most authoritative report to date.


"Only urgent, global action will do," said U.N. Secretary-General Ban Ki-Moon, calling on the United States and China — the world's two biggest polluters — to do more to slow global climate change.

"I look forward to seeing the U.S. and China playing a more constructive role," Ban told reporters. "Both countries can lead in their own way."

Ban, however, advised against assigning blame.

Climate change imperils "the most precious treasures of our planet," he said, and the effects are "so severe and so sweeping that only urgent global action will do. We are all in this together. We must work together."

According to the U.N. panel of scientists, whose latest report is a synthesis of three previous ones, enough carbon dioxide already has built up that it imperils islands, coastlines and a fifth to two-thirds of the world's species.

As early as 2020, 75 million to 250 million people in Africa will suffer water shortages, residents of Asia's large cities will be at great risk of river and coastal flooding, according to the report.

Europeans can expect extensive species loss, and North Americans will experience longer and hotter heat waves and greater competition for water, says the report from the U.N. Intergovernmental Panel on Climate Change, which shared the Nobel Prize with Al Gore this year.

The panel portrays the Earth hurtling toward a warmer climate at a quickening pace and warns of inevitable human suffering. It says emissions of carbon, mainly from fossil fuels, must stabilize by 2015 and go down after that.

In the best-case scenario, temperatures will keep rising from carbon already in the atmosphere, the report said. Even if factories were shut down today and cars taken off the roads, the average sea level will reach as high as 4.6 feet above that in the preindustrial period, or about 1850.

"We have already committed the world to sea level rise," the panel's chairman, Rajendra Pachauri, said. But if the Greenland ice sheet melts, the scientists said, they could not predict by how many feet the seas will rise, drowning coastal cities.

Climate change is here, they said, as witnessed by melting snow and glaciers, higher average temperatures and rising sea levels. If unchecked, global warming will spread hunger and disease, put further stress on water resources, cause fiercer storms and more frequent droughts, and could drive up to 70 percent of plant and animal species to extinction, according to the panel's report.

The report was adopted after five days of sometimes tense negotiations among 140 national delegations. It lays out blueprints for avoiding the worst catastrophes — and various possible outcomes, depending on how quickly and decisively action is taken.

"The world's scientists have spoken clearly and with one voice," Ban said, looking ahead to an important climate conference in Bali, Indonesia, next month. "I expect the world's policy makers to do the same."

The report is intended to both set the stage and serve as a guide for the conference, at which world leaders will begin discussing a global climate change treaty to replace the 1997 Kyoto Protocol.

That treaty, which expires in 2012, required industrial nations to reduce greenhouse gases and a smooth transition to a new treaty is needed to avoid upsetting the fledgling carbon markets.

"This report will have an incredible political impact," Yvo de Boer, the U.N.'s top climate change official, told The Associated Press. "It's a signal that politicians cannot afford to ignore."

The United States opted out of Kyoto in 2001, arguing that the science was unproven and that the burden of mandatory emission cuts was unfair since it excluded fast-growing China and India.

Chief U.S. delegate Sharon Hays said doubts have been dispelled. "What's changed since 2001 is the scientific certainty that this is happening," she said in a conference call late Friday. She did not indicate that Washington would abandon its policy of voluntary emission cuts.

China and India have said any measures impinging on their development and efforts to lift their people from poverty were unacceptable — a point likely to be heeded at the Bali talks.

The report offered dozens of measures for avoiding the worst catastrophes if taken together — at a cost of less than 0.12 percent of the global economy annually until 2050. They ranged from switching to nuclear and gas-fired power stations, developing hybrid cars, using more efficient electrical appliances and managing cropland to store more carbon.

Ban said a new agreement should provide funding to help poor countries develop clean energy resources, adapt to climate conditions and give them the technology to help themselves.

He said he witnessed the devastation of climate change in disappearing glaciers of Antarctica, the deforested Amazon and under the ozone hole in Chile.

"These scenes are as frightening as a science fiction movie," said Ban. "But they are even more terrifying because they are real."
