Answer 2

How about this...........you take the requirements of that essay and burn them. Global warming is a stupid THEORY. It's not this massive proven fact. Instead of doing what you are doing currently, take this to your teacher:

Global warming is one of the dumbest, stupidest, and ridiculous theories out there. Oh no, the temperature is raising. I'm sure our climate has never gone through changes in temperature before, this must be the first time..........NOT!

It's stupid to assume that just because the temperatures have gone up a bit that the Earth is going into a "global warming." Our climate has gone through changes before, it's stupid and ignorant to assume that it is the issue now. And the do you know how much the temperature has raised (According to the Intergovernmental Panel on Climate Change)? .6 degrees Celsius OVER THE LAST CENTURY. That is so significant, isn't it? I don't think so either.

And this slight SLIGHT raise in temp isn't our fault at all. Half of the global warming of the last century has happened between 1900 and 1945. If it was our fault, it would have happened more recently, seeing as we have been burning more fuel more recently.

So don't buy into the crap about how global warming will wreck us, it's all a bunch of stupid political garbage.

So, for your paper, get these points across:

1. Global warming does not exist,
2. The temperature has had an extremely slight raise, nothing that that will demolish us,
3. The slight raise in temperature isn't our fault.

If you do that, you are a real student.

Answer 3

The climate system varies through natural, internal processes and in response to variations in external forcing factors including solar activity, volcanic emissions, variations in the earth's orbit (orbital forcing) and greenhouse gases. The detailed causes of the recent warming remain an active field of research, but the scientific consensus identifies increased levels of greenhouse gases due to human activity as the main influence. This attribution is clearest for the most recent 50 years, for which the most detailed data are available. Contrasting with the scientific consensus, other hypotheses have been proposed to explain most of the observed increase in global temperatures. Among these hypotheses are that the warming is caused by natural fluctuations in the climate or that warming is mainly a result of variations in solar radiation.

None of the effects of forcing are instantaneous. Due to the thermal inertia of the Earth's oceans and slow responses of other indirect effects, the Earth's current climate is not in equilibrium with the forcing imposed. Climate commitment studies indicate that even if greenhouse gases were stabilized at present day levels, a further warming of about 0.5 °C (0.9 °F) would still occur.

Answer 4

Industrial Age Accelerates Global Warming
That changed with the start of the Industrial Revolution, when new agricultural and industrial practices began to alter the global climate and environment. Before that time, human activity didn’t release many greenhouse gases, but population growth, deforestation, factory farming, and the widespread use of fossil fuels are creating an excess of greenhouse gases in the atmosphere and contributing to global warming.

Science Links Global Warming to Human Activity
In February 2007, a report by the Intergovernmental Panel on Climate Change (IPCC), representing the work of 2,500 scientists from more than 130 countries, stated that human activity "very likely" has been the primary cause of global warming since 1950.

(In science, nothing is ever claimed to be "certain" or absolute, which leaves open the possibility of further research and discovery, but the term “very likely” indicates more than 90 percent certainty and is considered virtual confirmation.)
The IPCC report also said that human activity has been a major contributor to climate change since the start of the Industrial in the

Answer 5

More junk science from teachers who don't know how to analyze real data. The URL below talks about how the original published paper was flawed and talks about how the earth was really warm in the 14th century. It's actually cooler now than it was before the Industrial revolution in the 19th century. The 2nd URL talks about how the data was flawed.
Be a real renegade and say that global warming does not exist!

Answer 6

Here is a flow chart.

Use this link (to NASA), it describes the causes that are responsible. http://www.nasa.gov/worldbook/global_warming_worldbook.html

There are lots of evidence that supports global warming. NASA is a well-known and respected source. I think you'll find the information readily avaliable.

Here are the main portions of it (from NASA):
"Causes of global warming

Climatologists (scientists who study climate) have analyzed the global warming that has occurred since the late 1800's. A majority of climatologists have concluded that human activities are responsible for most of the warming. Human activities contribute to global warming by enhancing Earth's natural greenhouse effect. The greenhouse effect warms Earth's surface through a complex process involving sunlight, gases, and particles in the atmosphere. Gases that trap heat in the atmosphere are known as greenhouse gases.

The main human activities that contribute to global warming are the burning of fossil fuels (coal, oil, and natural gas) and the clearing of land. Most of the burning occurs in automobiles, in factories, and in electric power plants that provide energy for houses and office buildings. The burning of fossil fuels creates carbon dioxide, whose chemical formula is CO2. CO2 is a greenhouse gas that slows the escape of heat into space. Trees and other plants remove CO2 from the air during photosynthesis, the process they use to produce food. The clearing of land contributes to the buildup of CO2 by reducing the rate at which the gas is removed from the atmosphere or by the decomposition of dead vegetation."

Answer 7

Do you want to pick 4 greenhouse gasses and say they are the causes? CO2 is a contributing factor, but it is not a root cause.

Overpopulation: There are too many people for the planet to support

Overconsumption: We waste too much ... much of what we use every day is single use or "disposable". It takes energy to create these products, and a waste of it to throw them away.

Over-reliance on fossil fuel based technology: Our entire species has become lazy and overweight because we depend on "labour-saving devices" which rely in turn on fossil fuels for their source of energy.

Ignorance of our relationship with nature: We do not give nature any value beyond the value of the human time required to shape it to our wants and needs. We do not appreciate the inherent value of life. To kill a person has consequences, to kill a tree does not.

Answer 8

I will give you one manmade global warming contributor through irresponsible agriculure,

Everybody is so desperate to absolve humanity from blame ,and this is not possible

Global warming is one thing ,and for many people it seems to be the knight on a white horse that says
dont worry it is not your fault you can do nothing about it ,
keep on trucking ,poluting, deforesting, desertifying,
That is wrong
Man is responsible for much climate change it cannot be whitewashed by Global warming

Once upon a time
I went to the jungles of Oaxaca and discussed with the Natives the mountain before us ,Mostly deforrested ,scarred by landslides and dotted with madly steep corn patches (which only produced for 3 years ),and devoid of clouds.

They all agreed that the days were hotter ,there was less rain ,And the river was dry part of the year.

When they were boys ,the river was bigger and ran all year around,the mountain was always covered in clouds with daily rains .And the days were more bearable .

Their actions in the desperate plight to feed their enormous families of avarage 12 kids per family ,often much more ,had destroyed their home ground with indisputable climate changes.
They had changed their climate.This happens all over Mexico

In Africa I have seen lush wooded lands change into dessert within a few years by large invading comunities ,who devoured the trees for building and firewood ending up in a dessert with out water
and with a hot sun under which no new plantation was possible.The people had changed their climate,this happens all over Africa.

In Northern china two mayor dessert are merging and 900 vilages are buried under the dust ,thousands of refugee farmers who had changed their climate ,by intensive agressive agriculture are fleeing for their lives,this happens all over the world .it happened in the 20ties in the USA has everybody forgotton that ,was this not a climate change ?

Granted the climatic changes are local ,but effects neighboring areas ,there is less rainfall, rivers dry up ,

Collectively because there is so much of it all over the world ,the global precipitation is affected and so is the climate .And who did it ,the bloedy people did ,they are changing the climate

Like Ghengas Kahn changed the climate when he burned all the forests and filled the wells with sand ,Like the Phoenicians changed the climate of lebanon to build the trading fleet .Like the Spanish climate was changed by using their forest to build the Armada ,

So are we today changing the climate by massive deforestation,agressive corporate farming (using chemicals),overgrazing ,overpumping deep subteranean waters ,ignorence and impartiality

Global warming.carbon emisions ,polution ,sunspots ,solar flares,hairsprays , Al Gore, and skeptics are the rasberries on top

and read up what America is planning with the insane master plan for Ethanol production .http://answers.yahoo.com/question/index;_ylt=Av.LS_EpDKQU.HZFoH8IdwDty6IX?qid=20070530195737AACbd5b&show=7#profile-info-fHbzOdoIaa
Seems as if America is trying to compete with Global warming

I wonder who will win.?
but who ever it is ,
the rest of the world looses.

we are in trouble,and if we can do something that will make it less ,we should try to do it .

Answer 9

June 26, 2009, the yankee sparkling potential and risk-free practices Act became authorized to help with worldwide warming. The act goals to shrink united statesa.'s production of greenhouse gases by making use of 80 3% by making use of midcentury, and you recognize how the intense volume of greenhouse gases is a substantial portion of worldwide warming.. additionally renewable potential regulations have been exceeded in Australia and Europe besides.

Answer 10

In order; greenhouse gases (mainly CO2 and methane), changes in land use, increases in ozone at low levels in the atmosphere, the sun (about 10%). See the last website for details/proof.

Answer 11

Oh, I hope your school is not teaching you this global warming BS. This deserves no place in a public school curriculum.

1. The sun: Every 11 years the sun goes through a cycle. Right now we are in a warm cycle. In another 7 years Earth will be cooler again.

2. The underwater conveyor belt: There is a current running throughout the ocean that keeps the Earth warm. It is driven by the salinity of the ocean. The earth gets warm, glaciers melt, sea gets less salty, the conveyor slows down, earth gets cooler, it's an endless cycle.

3. Ozone layer: Ozone traps 12% of our atmospheric heat. When there was a hole in it, it let out heat. (The ozone hole was fixed in the 90's)

4. Greenhouse gases: CO2 levels have risen small ammounts due to humans. CO2 is very weak and it is heavier than air though. Methane is 23 times as strong as CO2 and is lighter than air. N2O is 21 times as powerful as CO2.
