Global Warming Is A Crock

I think that the global warming through the release of greenhouse gasses theory is completly false. Anybody agree? Or want to prove me wrong ?

Well, global warming definitely exists. The big question is if it's attributed mostly to a natural earth process, or is in the hands of man. I think it's a little bit of both, though there is still a lot of research to be conducted before a conclusive answer can be reached.

 

My problem is that it's become so wildly accepted as truth nobody questions it, and I can't seem to find any solid evidence that "greenhouse gasses" are causing the planet grow warmer....

 

You may have yet to see substantial proof that global warming can be attributed to “greenhouse gasses”.

I have to wonder, though, upon what basis you know that global warming is a natural phenomenon? Can you provide solid proof for your position? Or is it derived solely from the lack of proof on the part of your counterpart?

I would like nothing more than for this global warming nonsense to be dismissed as a natural phenomenon, but the most convincing proof I have come across accentuates the role of air pollution.

 

i think it hopeful thinking that humans are not destroying the earth in te multiple ways that they are.

 

At first I read 'Global Warming Is A Cock', but then I lost my interest in this thread.

 

There is no solid proof that it isn't due to humans, but there is no proof nor logic to the greenhouse gasses theory. Unfortunatley thats how the scientific theory works, you can't just invent a theory and then ask people to prove it wrong. You present your theory with evidence to back it up and see if it stands up to experimentation. I've been looking and I can't find any solid evidence for this theory.

I'm far from being well educated in this field, but wouldn't it be more difficult for the suns rays to penetrate all of these gasses? Nuclear winter theory?

 

its those damn cows belching....

 

No. Such radiation would be absorbed by the ash in the air. The ash wouldn’t keep in the heat from the earth.

This doesn’t say much of anything. You have merely avoided the question. You know for a fact, as is evident in your posting in this ... http://www.hipforums.com/forums/showthread.php?t=43475 ... thread that there is at least some evidence available to you that suggests the human influence in the process.

(Unless you post without knowing what you are posting in response to)

You haven’t provided any proof of your theory whatsoever.

In your own words ...

.

So why should we be listening to you again?

 

Isn't more like the ash would reflect the sun's radiation, preventing it from reaching the earth? So it would still block heat loss, but it would prevent any new heat energy from getting in, thereby reducing temps... Whereas greenhouse gasses do not reflect the sunlight (at least not anywhere near as much), so the heat gets it, but doesn't get out...

I don't really know much of the evidence... My boyfriend does, & I trust him to give me an acurate synopsis... One of the things that's really interesting (to me, I'm a nerd) is what could happen due to this global warming -- somehow, I don't remember the specifics, but the melting of the ice caps could trigger some chain reaction that could basically send us into another ice age within a relatively short time span... Yeah, I'm sure this sounds like crap, since I'm trying to remember what my bf told me about what his geology prof told him & I'm not doing such a good job of it, but...

 

Sorry, this is going to be long and dull.

Poor psilonaut, methinks you've been hanging around too many republicans lately. I'm definitely no expert, but I pulled this out of a textbook and stuff.

Theory: Humans are raising the temperature of the planet through greenhouse gas emissions (mainly CO2, but others).

Facts: Since the Mauna Loa Observatory started taking measurements, atmospheric CO2 levels have been rising. In 1960 the atmospheric concentration was 317 ppm, in March of this year it was 379 ppm. Also, they reported that not only are the levels increasing, but the rate of increase is increasing - think of all those people in asia who are starting to drive cars like we do. Estimates from climate records (e.g. ice cores) show that CO2 levels in the 1850s were about 280 ppm. Of CO2 emissions today, roughly 80% comes from people burning fossil fuels, 20% from natural sources. CO2 contributes to about half of the overall greenhouse effect. CFCs contribute to about one fourth, and those are all from human activity. Methane (both human and non-human sources) makes up about 15%. Altogether, humans spew out about 75% of the so-called greenhouse gases. These "greenhouse gases" are called that because of their undisputed physical property of allowing short wavelength UV rays to pass through but not allowing longer wavelength infrared rays. Energy from the sun enters as UV, is absorbed by the earth, and then emitted back as infrared.

Measured average global temps have risen about 0.6 C since 1960, and records show that the 1990s were the hottest decade of the 20th century. Estimated temps from climate records (e.g. ice cores, trees) indicate that the 20th century was the hottest century in the last 1000 years, and that the 1990s were the hottest decade in those 1000 years. (Remember that climate is measured over long time periods.) Global warming seems to be mostly impacting the upper and lower latitudes. So more impact on the polar regions than where we live. This can be seen from the melting of polar ice caps. In the arctic NASA estimates the ice cap contracting at a rate of 9% every decade. Biologists in places like Alaska have already noticed changes in wildlife migration and feeding patterns as a result of melting glacier ice.

Lastly, climate models show that increases in CO2 and other greenhouse gases do result in temperature increases comparable to what's been measured. They also show that at current rates of greenhouse gas increases the global temps will continue to rise. A model is just a model though.

So atmospheric concentrations of greenhouse gases have risen significantly in the last 150 years. Humans are the cause of the majority of these gas emissions. Climate models predict temp increases with increases in greenhouse gas concentrations. Global temps have been measured to be steadily increasing over the last 150 years. Effects of these temperature increases have already been noticed in the polar regions.

There are some unknowns: Are the temp increases really due to human activity? I dunno. Temps have been increasing steadily since the last ice age, so maybe there is some purely non-human factor responsible for this increase.

Will temps continue to increase with greenhouse concentrations? Models predict yes, but its certainly possible that something could alter that. There are many even small things that can have a dramatic impact on a system as complex as global climate. e.g. I remember learning one theory of why we have ice ages is because the earth's rotational axis is slightly wobbly (changes in the axis alters the amount of light that hits different parts of the planet), and in cycles of every 20000 years or so these axis changes cause ice ages. These forces may prove to be of greater influence than CO2 concentrations, but do we really have 5000 or so years to wait for the next ice age to start?

Last point. In europe, people invoke something called the Precautionary Principle. This states that when the outcome of an action is unknown, but runs a high risk of being negative or even a small risk of being highly negative, then don't do it. Are there possible devastating consequences of sudden or even gradual climate change? Is there a possibility that our actions will result in climate change? If so, the precautionary principle states that we must change our behavior. Stealing the words of my favorite national security advisor (not!, bitch!), we can't wait until the smoking gun is a mushroom cloud.

 

There is scientific proof that Global Wraming occurs through the release of high levels of Greenhouse Gases.

Look up info on the Mid-Cretaceous Superplume Event on google.

 

Well put ntphishin, but all of these studies have only been observing the last few decades. Thats a half a wink of an eye in the grand scheme of time on earth. Like you said, there's no solid proof that this increase in temperature is the result of humans.

Now I'm not saying we should start polluting like theres no tomorro, clearly these gasses are harmfull to ourselves and other living things on this planet. That being said, I still bothers me that this global warming theory is so wildly accepted as truth. There are plenty of studies that have proved it wrong .

 

There is evidence, but far from solid evidence. It's been proved wrong by many studies.

Because I don't have a theory. Everybody knows that the earths temperature goes through cycles of climatic change, there is no denying that, I have no reason to beleive that it is due to humans that the earths temperature is rising.

This reminds me of a cartoon...Can't remeber wich, but there were two cavemen sitting inside a cave, one standing by a fire and the other pointing to a lightning bolt outside procaliming "It never used to do that until you started that!"

 

Hmph, all that typing for nothing.

 

Mother Earth is heating up from the inside. She is conscious, and changing her skin. Her passion, fire, kundahlini is running again and bringing forth grand changes. Both to her, and in turn, will force them living upon her to change as well, and, change with the tides, so to speak.
Now many people may speak against this because I commune with Mother Earth herself, many people many not understand or even, desire to experience this.
BUT
The planet is a conscious being, just like you and me. And she chooses at this time to heat up, heating up the core. She is both heating up, and growing at the same time....

Namaste

But, doesnt it make sense to you? think about it.. the earth and atmosphere give us certain amount of resources... if they are abused, things will run out quicker. i dont need prove to know what i feel.

 

Maybe it's HAARP?

 

But because you "feel" it should the rest of the world also beleive it? There needs to be proof, thats how the scientific process works...

 

and what? you think global warming is accepted?

look at the gov. and half of the american people and then tell me that it is soooo widely accepted.
