Global Warming is Fake?

Question

I have a challenge for all the people that believe that global warming is caused by people. Explain to me how people cause global warming when man is responsible for only 3.4% of carbon dioxide emitted to the atmosphere annually. Everything else is all natural. Mars is losing its ice caps just like earth. It has approximately the same average temperature increase also. Did you ever think that it could be the sun causing it? Otherwise that means our CO2 is traveling to Mars.

The planet has obviously gone through heating and cooling cycles dating back thousands of years ago. There is scientific proof of dinosaurs, and what killed them all off? An Ice age. The ice ige is over so what happened? Global Warming. The planet's temperature is natural and there is no way that man kind can control the enviroment. The earth will continue going through natural cycles just like it has forever.

Answer 1

How can people cause global warming when we emit only 3.4% of all CO2 emissions? That's like asking how a company with a million dollars in annual revenue can go bankrupt. It's easy: if the expenses are $1.034 million a year, after 50 years the debt has exceeded annual revenue by several times and down it goes. Eventually the piper must be paid.

And that's exactly what's happening with CO2 in the air. Without fossil fuel burning, the air is in balance and CO2 levels remain static. With fossil fuel burning, the balance is upset -- and after enough decades eventually the piper must be paid. Well, payoff time is right now, and guess what? We're bankrupt.

From time to time all planets go through climate changes for natural reasons -- and we know what those reason are. Mars may or may not be going through a climate change now. And so what if it is? We know what causes climate change on Mars, just like we know what causes it on Earth. And it's not the Sun. At least not this time.

Do you know what irks me about people like you, studly? You don't read, and you don't understand, the basic science before shooting your mouth off. If you did, you'd know that there is unchallenged evidence that the current warmth is caused by increased greenhouse effect. That's UNCHALLENGED evidence, studly. I won't go over it again, but if you run through a few of my past answers on this section, you won't have any trouble finding it.

You act like a drunken fan running onto the field during the game, thinking he can take down the nose tackle all by himself. Go do a few pushups first, studly, and let the pros do their job, because in the meantime you're just annoying those of us who understand the game. Here's where you can start.

If you can't hack this kind of stuff, do us all a favor and stick to the sports section.

Answer 2

The obvious explanation is that you're only getting part of the information. This seems to be a popular tactic.
We keep putting out 3.4% but it has built up over time and now the natural resources that deal with it are not able to keep up.
Mars is getting warmer b/c it is going through a cycle of producing a lot of dust storms which darken the surface...which enables it to attract more heat.
The heating trend is moving much more quickly than it naturally should. The global catastrophe that caused the ice age was associated with a meteor strike wasn't it? That would mean it was not just a phase the earth went through.

Answer 3

Do you really think climate scientists haven't considered this?

The natural carbon cycle absorbs slightly more CO2 than it emits.

http://en.wikipedia.org/wiki/Carbon_cycle

Then on top of that, by burning fossil fuels we're emitting billions more tons of CO2 every year. Compared to the natural carbon cycle this is a small amount, but it's more than can be naturally absorbed, so it accumulates in the atmosphere. Since CO2 is a greenhouse gas, this increases the greenhouse effect, and thus causes global warming.

Mars is warming because dust storms are darkening its surface.

http://www.space.com/scienceastronomy/070404_gw_mars.html

Most planets and moons in the solar system are not warming. If that's not enough evidence that the Sun isn't responsible for global warming, just examine the Sun's output directly.

Here's a challenge for you. If the current warming is natural, then why is the planet warming 20 times faster than when it naturally comes out of an ice age?

Please take some time to learn about the science behind global warming.

Answer 4

So who was recording the global temp 2 to 3 hundred years ago? An who are these pros that are spoke about Al Gore is he a scientist or maybe its the fine people in hollywood?

Answer 5

That misleading comment "Humans contribute approximately 3.4 percent of annual CO2 levels" has been attributed to the National Center for Policy Analysis, which has received $465,900 from ExxonMobil since 1998.
http://www.exxonsecrets.org/html/orgfactsheet.php?id=55

Look at the wording carefully, it does not say "3.4% of annual releases" it says "3.4% of annual levels," of total volume. If we "contribute 3.4%" each year, after 10 years our "contribution" would increase CO2 levels at least 34%, and in 30 years CO2 levels would double. Yes, we have a big problem.

Here's an account of the overall net flows, both positive and negative:

Carbon Dioxide Budget of the Biosphere
http://www.ccas.ru/tarko/co2_e.htm
Calculations show that the CO2 flows balance of in the world in 1995 was as follows.

Industrial releases - 6.41 Gt C/ year,
Deforestation - 1.08 Gt C/ year,
Soil erosion - 0.91 Gt C/ year,
Absorption by terrestrial ecosystems - 4.05 Gt C/ year,
Absorption by ocean - 1.05 Gt C/ year,
Remains in atmosphere - 3.30 Gt C/ year.

You can see that industrial releases are the big culprit, but we also contribute to deforestation and soil erosion.

The bottom line: the earth was able to absorb some of our Co2 production, but industrial releases alone would have to be cut by more than half to bring the balance close to neutral. Apparently virtually no one is discussing cuts sufficient to curb global warming.

'Unexpected growth' in CO2 found
http://news.bbc.co.uk/2/hi/science/nature/7058074.stm
BBCNews.com, Oct. 23, 2007

Excerpts:

Carbon dioxide (CO2) levels in the atmosphere have risen 35% faster than expected since 2000, says a study.

About half of emissions from human activity are absorbed by natural "sinks" but the efficiency of these sinks has fallen, the study suggests.

The research, published in the Proceedings of the National Academy of Sciences (PNAS), was carried out by the Global Carbon Project, the University of East Anglia, UK, and the British Antarctic Survey.

It found that improvements in the carbon intensity of the global economy have stalled since 2000, leading to an unexpected jump in atmospheric CO2.

"In addition to the growth of global population and wealth, we now know that significant contributions to the growth of atmospheric CO2 arise from the slow-down of natural sinks and the halt to improvements in the carbon intensity of wealth production," said the study's lead author, Dr Pep Canadell, executive director of the Global Carbon Project.

"The decline in global sink efficiency suggests that stabilisation of atmospheric CO2 is even more difficult to achieve than previously thought," said report co-author Dr Corinne Le Quere of the British Antarctic Survey.

Answer 6

Noreally fake, but definitely not man made. Science has shown the temp to have increased about 1 degree in the last century. What science has never been able to show is a link between mans activity and global warming.

It has now gotten to the point that the entire issue is political.

Answer 7

So that I can provide a detailed answer to your question I'll take each point you make in turn...

<< I have a challenge for all the people that believe that global warming is caused by people. Explain to me how people cause global warming when man is responsible for only 3.4% of carbon dioxide emitted to the atmosphere annually. Everything else is all natural. >>

The atmosphere consists of many gases, the greenhouse gases make up a tiny but vital part of the atmosphere - in total it's just 0.0388% and almost all of this is carbon dioxide - 0.0387%. Another way of expressing it is 387 parts per million by volume (ppmv). For the three million years that humans have been on the planet in one form or another levels of CO2 naturally fluctuated between 180 and 290ppmv. In the last 250 years, and most notably in the last few decades levels of CO2 have risen from 280 to 387ppmv. What we've effectively done in a few decades is to replicate the same increase that naturally occurred across a 3 million year timeframe. In percentage terms it's a 38% increase in CO2 levels.

There have been similar rises in levels of other greenhouse gases and across the board the overall increase is 40%. Far beyond anything that could naturally occur and a rise so fast that it's never before been known at any point in the half billion years of climate data we have to work with.

Levels of CO2 have been higher than they are now but this has been the culmination of a built up over millions of years, not a few decades.


<< Mars is losing its ice caps just like earth. >>

It's only losing the southern polar ice cap, the northern polar ice cap is expanding. The articles that skeptics often quote from clearly state this but conveniently many skeptics omit the part about the northern polar ice cap, the result being that you often only get to hear part of the story. There's only one source of information about that's really happening on Mars and that is of course, NASA. Check their website, there's lots of info about Mars and one thing that is made abundantly clear is that the warming there is in no way linked to the warming on Earth.


<< It has approximately the same average temperature increase also. >>

In some parts it probably does, globally it doesn't - warming on Mars is localised.


<< Did you ever think that it could be the sun causing it? >>

This has been visited many, many times over. It has been discounted many, many times over. We have a range of ground based instruments and satellites that are capable of accurately recording even small changes in the Sun. Since the 70's total solar irradiance (heat from the Sun) has declined slightly, not much but enough to cause slight cooling if there weren't any other factors involved.

It's frequently pointed out that some planets and moons in the solar system are warming. Again the skeptics are guilty by omission here because they forget to add that in each case it's due to circumstances unique to that particular solar body (apart from Triton which is warming but we don't yet know why). Another thing that conveniently gets overlooked is that there are more planets and moons cooling than are warming.


<< Otherwise that means our CO2 is travelling to Mars. >>

The surplus CO2 (and other greenhouse gases) are accumulating in the atmosphere. There are natural cycles which release and absorb over 200 billion tons of CO2 each year - namely the oceans, biomass and soil. They're more or less in equilibrium but do have a slight surplus capacity and can absorb an extra 3 billion tons of CO2 a year. Unfortunately this is far short of human emissions, in 2006 we produced 29 billion tons of CO2, this year it looks like being 31 billion tons - it's about 10 times more than nature can handle. All this surplus simply accumulates in the atmosphere and contributes to global warming.


<< The planet has obviously gone through heating and cooling cycles dating back thousands of years ago >>

In the last few thousand years there's been almost no change at all in temperatures. The most notable event that occurred was a period known as the Medieval Warm Period, this was the culmination of over 1000 years of warming in which the average global temperature increased by 0.6°C, at today’s rate of warming this would be achieved in just 34 years. For 10,000 years the average global temperature rose by just 1°C, today temps are rising 177 times as fast.

Going further back in time there have indeed been many occasions of notable warming and cooling. These are caused by the complex interactions between the cycles of the Sun and Earth. But again, these changes occur very slowly over thousands or even millions of years. Perhaps the most dramatic event was the ending of the last ice age. In natural terms the temperatures were soaring almost out of control - almost by 1°C per 1000 years (19 times slower than present).


<< There is scientific proof of dinosaurs, and what killed them all off? An Ice age.>>

The dinosaurs died of at a time when the world was a lot warmer than it is now, during the warm period before the onset of the most recent full ice age. It is believed they were killed off by a massive meteorite impact, this would have had a catastrophic but short term effect on the climate.


<< The ice age is over so what happened? Global Warming. >>

The most recent short term ice age is over, it finished 10,500 years ago and was, as mentioned, brought about through the natural cycles of the Sun and the Earth. These vary in length from one day to 430,000 years, there's several of them (I won't explain them in detail here but feel free to email should you require more info). Each individual cycle can cause warming or cooling, it's the sum of the warming and cooling effects that produces a net result and ice ages come and go following a regular pattern that ties in with these cycles.


<< The planet's temperature is natural >>

Unfortunately it's not any more. As mentioned earlier, for 10,000 years the climate has been stable with hardly any change in temperature, this trend should have continued for many more thousands of years (with short term ups and downs). Right now the actual temperature is almost 1°C higher than it should be. It doesn't sound a lot but in nature many things are delicately balanced and a 1°C change in temps can have serious implications.


<< and there is no way that man kind can control the environment. >>

We have already affected the environment in the past with the depletion of the ozone layer, acid rain and global dimming. All inadvertent consequences of our modern lifestyles. These were all very real events, global warming is just the next in a serious of human induced environmental changes.


<< The earth will continue going through natural cycles just like it has forever. >>

Yes it will and it will keep warming and cooling naturally. In time ice ages will come and go and in the larger scheme of things there will be massive upheavals on the planet.

As I hope I've explained, the current warming is outside that of any natural cycle. If our climate were solely dictated by natural cycles then the planet should be cooling. It's not and the reason is the simple physical property possessed by the greenhouse gases that enables them to absorb and re-emit thermal radiation within our atmosphere. This isn't anything new or unusual, it's the very mechanism by which the planet maintains a habitable temperature. Were it that the greenhouse gases were bereft of this property Earth would be a ball of ice upon which life would never have evolved.

Answer 8

So, you say it is a fake. Fine.
But the real question is, what do you want to do about it?
Do you still cross your hands and do nothing?
Let say it is unpreventable, but speaking of an effort worth make, WHAT DO YOU DO ABOUT IT???

Check out the sources, maybe can help you "realize"...

Answer 9

its fake buddy your correct all it is, is the ice age letting out....im so glad some people understand that

Answer 10

Nothing to answer because I pretty much agree with what you are saying!
