Do humans really have anything to do with global warming ?

Question

Does global warming really have anything to do with greenhouse emissions, or are fluctuations in the earth's temperature caused by nothing more than variations in the sun's energy output, which are natural cycles that have been going on for hundreds of millions of years ? Think about times in earth's history when it has experienced more tropical conditions, likewise, iceages. These natural cycles had NOTHING to do with humans ( who were not around then ) , no matter what Al Gore says !

Answer 1

You are forgetting a valid point that Al Gore made as well as a vast majority of scientists (the ones that disagree are probably paid by Exxon Mobile). The average temperature of earth today is many times that then ever before during this part of the cycle. We have never reached this temperature increase or rate of increase. There are two possible reasons for this. Either the sun has doubled in size (yes, I'm exaggerating) or we are ******* things up. Yes, there are cycles, but the way things are going we are not following the cycle we have in the past. Greenhouse gasses are the cause of that.

Answer 2

Climate change is mostly the result of anthropogenic (human) causes. Agree or disagree?

This question was part of a survey answered by 530 climate scientists in 2003. Only 9.4% answered "strongly agree".

Yet the U.N. is telling us that they're 90% certain that global warming is caused by humans. The politicians spin the facts to fit their agenda.

The post above this one by haha10488 is a perfect example of how people are duped by propaganda. The world has been this warm many times in the past and without help from humans, thank you very much.

The computerized climate models in use today are so primitive that they do not even attempt to account for basics like cloud cover, precipitation, volcanic emission, or variations in the sun's radiation. Also consider that the in the 1970's the alarmists were warning us of the new ice age.

"We simply cannot afford to gamble...by ignoring it. We cannot risk inaction. Those scientists who say we are merely entering a period of climatic instability are acting irresponsibly. The indications that our climate can soon change for the worse are too strong to be reasonably ignored."
--The Cooling: Has the Next Ice Age Already Begun? by Lowell Ponte, 1976

Answer 3

Global warming is 100% humans fault.

When the last ice age ended (the actual START of global warming) cavemen were driving biga$$ed SUVs, working in massive factories and cutting down the rain forests.

Just listen to Al Gore the great inventor.

Answer 4

You can make that argument. But it is undeniable that carbon dioxide levels are way up in the last 200 years, far above any natural variation of the last 400,000 years, and the rate of increase is increasing. Even if it hasn't played an important role in warming yet, at some point in the future, if we keep doing what we are doing, it will.

Answer 5

We as humans make up 2% of all geenhouse gasses(H2O #1) and 4% of the CO2. If we cut what we do by 1/2 it will only drop the CO2 by2%( By the way to do that we could only stay at home and breath) Do you think a 2% is going to stop the warming. this is cutting growing and transporting of food as well.`

The coldest temp on earth was in 1997.
The hotest temp on earth was in 1917.
What?

Answer 6

Global warming is not natural. Here's why I say that.

The problem with analyzing climate is that there's only one way to do it. You must look at a lot of data and do methodical analysis.

When you do that, all the ideas for it being natural are completely destroyed. But it takes data, not intuition. Here goes.

Solar variation. Carefully measured data on solar radiation (done repeatedly by many people in many places) shows the increase in solar radiation is 0.12 watts per meter squared. The increase in heat due to man's activities is 1.6 watts per meter squared, more than ten times as much.

http://www.ipcc.ch/SPM2feb07.pdf Page 4.

Volcanoes. They create about 1% as much greenhouse gas as man does, and they create dust, which cancels that out.

http://www.geology.sdsu.edu/how_volcanoes_work/climate_effects.html

The natural world is incapable of absorbing the excess CO2 that man creates by digging up carbon buried naturally over many many years, and burning it real fast. The small teeth are nature (seasonal variation), we're the big surge upwards. We're "winning" big time.

Serious people know that just arguing generalities doesn't work here, you actually need to look at the data, or check with someone you trust who has.

The people below have done that. They are mostly not liberals, or environmentalists. They didn't get their information from Al Gore (mostly they're mostly no fans of his, and they know Gore has absolutely nothing to do with the science). They're serious people and they got their information from the best scientists in the world. They also know about people who thinks it's natural, and they have listened to them also. They're not buying it. They think humans are the cause. You may not respect all of them, but surely you respect some.

"The science of global warming is clear. We know enough to act now. We must act now."

James Rogers, CEO of Charlotte-based Duke Energy.

"The overwhelming majority of atmospheric scientists around the world and our own National Academy of Sciences are in essential agreement on the facts of global warming and the significant contribution of human activity to that trend."

Russell E. Train, former environmental official under Presidents Nixon and Ford

"Global warming is already starting, and there's going to be more of it. I think there is still time to deal with global warming, but we need to act soon. Humans now control global climate, for better or worse."

James Hansen, PhD, climate scientist, NASA

"By mid-century, millions more poor children around the world are likely to face displacement, malnourishment, disease and even starvation unless all countries take action now to slow global warming."

Michael Oppenheimer, professor of geosciences and international affairs at Princeton University

"We simply must do everything we can in our power to slow down global warming before it is too late. The science is clear. The global warming debate is over."

Arnold Schwarzenegger, Republican, Governor, California

"Our nation has both an obligation and self-interest in facing head-on the serious environmental, economic and national security threat posed by global warming."

John McCain, Republican, Senator, Arizona

"These technologies will help us become better stewards of the environment - and they will help us to confront the serious challenge of global climate change."

President George Bush

And the data is why the vast majority of scientists think it's not natural, but us.

http://www.sciencemag.org/cgi/content/full/306/5702/1686

People can trot out all the "logical" arguments they want. They can attack Al Gore's personal life. But the scientific data is completely overwhelming. This is the best summary of it right now. Thousands of scientists created it, and it underwent massive peer review. It's solid, and actually very conservative, as anything created by a large group of people is.

http://www.ipcc.ch/SPM2feb07.pdf

Global warming is real and it's us. Denying it is not scientific, it's right up there with denying we went to the moon or saying someone has a perpetual motion machine.

Answer 7

Maybe God put us Earth to stop these wild fluctuations.

Answer 8

Is global warming a man-made menace?

not all there are natural cycles in the planets life
but a lot is influenced by mans existance ,and this is increasing with overpopulation,putting strains on Natural resources and increasing contaminations as well as destructions of essential componants the ensure living conditions for all life forms

some home truths

politicians and scientists who work for politicians have downplayed the facts because solutions are expensive and means change and change effects many people income,and most of the world is kept in the dark of the real things that are going on.


in North Africa,India,Mexico ,millions of people are effected by land loss and desertification


in recent times thousands of people have died because of exessive heat,usually old people.in India ,Mexico and France,
deforestation causing desertification,the desert conditions causing very cold nights and scorching hot days

in china, thousands of what used to be farmers are running for their lives from the dust storms that have burried their towns and turned their lands into dessert,the globe where they were got to hot for them .
and instead of producing food they are now needing it from some where else,and they will drastically effect the world food prices when they start buying water in the form of grains ,at any cost destabalising governments, in some countries ,could be the result
(are you seeing more Chinese around interested in agricultural lands ,we do here in Mexico)

,the Sahara is growing by 7 kilometers a year
and all of the desserts we know are a results of mans actions ,and they are increasing ,not getting less ,in the dinosaurs days ,there were no desserts.

collectively this planet is drying up because of bad farming practices like,over grazing and fertilizers,

as far as the food production is concerned, Global warming or some of its effects are serious,rising seas result in landloss

each degree rise in temperature means 10%crop loss

more landloss because of desertification every year,we have less areble land to produce food ,for an extra 70 million people ,

and there is less and less water (because of deforestation),to irrigate this production ,
and there are less and less farmers to do it..
who are overpumping deep carbon aquifiers
who are plowing more and more unstable lands because they have lost so many million hectares to desertification ,
because of bad farming practises ,such as using fertilizers and heavy machinary or over grazing

RISING SEAS
The northpole is melting ,and we will know it without ice in our life times.
this does not affect the sea level because it is ice that is already in the water.but the melting ice from Green land and the south pole ,are another matter.

Global warming is in theory reversable,but it will mean global co operation between all countries ,and taking into account human nature and the world politics ,it is unlikely that this will happen,

At least not untill we are all in the middle of planetary disastres and it becomes a battle for the survival of humanity every where.

SOLUTIONS
if you want to help the planet ,plant a tree every week ,if everyone on the planet did we we would be able to reverse the destructive processes

reduce carbon emisions,and they are already working on that by alternative forms of energy and regulations on carbon producing materials,aerosol cans,burning rubbish,industrial chimneys,powerplants etc.

the capture of carbon and the production of water and assist the aquiferous manta.

the world bank pays large subsidies for reforrestation to capture carbon and the best tree for this is the Pawlonia

Waterharvesting projects ,such as millions of small dams.to redirect over ground waterflows from the rains into the ground to supply subteranian water supplies.

the protection of existing forrests.

stop building more highways,urban planning to include vegetation stop building cities encourage people to return to the land to conduct their business from there which now has become possible thanks to the internet.

education to motivate people to auto sufficiency by building more home food gardens.

education on environmental awareness
education on family planning to curb over´populaion

Agricultural education and improvements to follow the principals or sustainability and soil management.

more environmental or land ,design to prevent bush fires,such as--fire breaks

,more dams.regulations and control for public behaviour

alternative effeciant public transport to discourage the use of the internal conbustion engine

recicling wastes,limit water use

Answer 9

One, worldwide warming is a fable. Quote by utilising Will Harper, Princeton college physicist, former Director of power examine on the dep. of power: “I had the privilege of being fired by utilising Al Gore, when you consider that I refused to pass along with his alarmism....I easily have spent an prolonged examine occupation examining physics it is heavily with regard to the greenhouse consequence....Fears approximately guy-made worldwide warming are unwarranted and are not in line with stable technology. The earth's climate is changing now, because it continuously has. there is not any info that the diversities selection in any qualitative way from those of the previous.” 2, there is not any info that guy is inflicting any replace in temperature. CO2 is going up and over the final decade the temperature has long previous down. 3. guy would not in my opinion or mixed have adequate power to alter the earth's temperature. In different words, we can't.

Naw--its all the other animals...
