Global warming isn't real

mitch you would have been good in the DL when it was active.

you write a ton of shit every post.

i used to...but its really really hard now :P
 
you forget what is possibly the most important part of CO2 emissions. when we burn CO2, we take all this potential energy in chemical bonds, energy that was once kinetic now transformed into bonds, which takes away heat. now, in addition to the greehouse effect, we are turning huge huge huge amounts of potential energy into kinetic energy (aka heat). im going to make some approximations here to give you an idea of what global warming and CO2 emissions have to do with each other. we are not only pumping CO2 into the atmosphere, we are also pumping heat. and lots of it. burning one mol (about 75g) of gasoline releases enough energy (~40000kJ/kg)times ~0.1)=4MJ to heat 800kg of water 1 degree celsius(because 5kJ raises 1kG of water 1 degree celsius) . now think about how much gas you burn personally in a day (on average lets say 20 times that, between electricity usage, driving anywhere, and doing laundry or watching tv. so on average you are raising 20 kg of water 1 degree. now lets say a billion people in the world are doing this. holy fuck, eh. thats global warming for you.
 
i read it and i couldnt agree with you more completely.

even tho politics can be enviromental, the enviroment is not political...so people shouldnt chose side on this issue based on what their plitcal views are.

and you cant deny that temperatures have been rising and that global warming is a prevolant(sp?) issue now, so unless we do something about it, shit's gonna continue to go down the tubes.
 
While it is true that the temperature is increasing, we don't know if the earth is somehow able to counter-balance for this mini climate shift. Nature is far more advanced than man can ever perceive. I mean we learn new things about it every single day.

It sucks politicians misinterpret environmental issues and environmental facts to us, but we have to look beyond that.
 
We arent wearing gas masks because we DID cut down on pollution after the 70's. Lake Washington (near Seattle) used to be fucking nasty, unfishable and unswimmable back then, because all the cities dumped thier sewage into it. Lots of cities (like New York) did stuff like that during the 70's. Clean air and water acts were then passed, which lowered the rate of pollution drastically across the US. Thats why were arent going to school and work with face masks.

Is pollution still effecting our populations? Well... look at asthma rates in our country's children, its getting to epidemic-like levels.
 
Honestly, I feel that political reasons are motivating most of the research being done on the issue of global warming. Bush would like global warming not to be an issue so that he can lower pollution mandates in the US and allow companies to increase profits by slacking on environmental protection policies. He would also love to drill all that said oil in Alaska. Does he really care if the earth is warming up? No. Does Gore care? No, he's doing this for popularity. Nobody seems to be honestly in thier supposed concern with this issue, it all backs alterior motives.

But the facts are this. Human pollution effects our environment. We are the most destructive creatures to ever walk the earth. We cause change. To what extent we do so can be under debate, but all that matters to me is that we make a footprint. Pollution causes a lot of bad things, not only to the environment but in our own population as well. And besides, I'd rather live in a world that isnt smoggy and shitty anyways.
 
heres something we can agree on: spitting billions of pounds of pollution into the atmosphere that we breathe is not good. has anyone ever been to LA? the air there is really, really fucked up. we dont want to all be breathing that shit, so we should cut down on our emissions. end of story.
 
you are a complete retard, half of the reason why the planet is going to shit is because of people like you who keep downplaying global warming like its no big deal

having no snow to ski on is a big deal
 
i don't know if you've ever heard of MIT, but the people there are kind of smart. and here's what they've published about the issue.

http://www.technologyreview.com/Energy/17057/page1/

and that jim hansen guy they talk about? only the most reputable climatolagist in world. don't go throwing this "climate change" isn't real bullshit around just because you want to be different. really do your research. don't just look for sources that say what you want them to because you can find a website that says just about anything.

Here are the undisputable facts of climate change:

1) CO2 is a greenhouse gas along with many others such as methane and NOx

2) Greenhouse gases trap infared radiation that would normally be reflected back out into space, causing a warming effect

3) The amount of CO2 in our atmosphere is increasing (at 377 ppm, it has increased 32% since 1850) and this increase is due to anthropogenic causes

4) What affect this is going to have on the Earth's climate is completely unpredictable.

Due to feedback cycles the Earth may not actually get any warmer. All the models you've seen and heard about are complete speculation. Changes are going to take place, but no one knows what they are. All we can do is take preventative measures to limit the effect that humans have on the natural climate cycle. Anyway, I'm done ranting about this. enjoy.
 
id just like to point out how global warming doesnt affect just us... or certain people.. but the entire world. As well as some examples of the effects of global warming. Whether you care or not... im just trying to inform.

Example 1.The caribou population in Alaska has been on a steady decline the past few decades because of the drastic increase in mosquitos and the increasing harshness of storms. The increase in mosquitos can be attributed to the warmer temperatures elongating their breeding season. And in turn, the caribou climb to higher altitudes to escape the mosquitos, which requires high amounts of energy and once they get there, there is a limited food source. So when winter comes, the caribou are already weaker and cannot take the increasing intensity of storms. RAIN is also a killer. For the first time, these areas have been experiencing rain in the dead of winter, which causes a thick layer of ice over the ground prohibiting the caribou from being able to reach their food source (lichen) in the winter. The depletion of caribou puts an entire tribe of people who strongly depend on them in danger.

 
Example 2. Drier and hotter weather in the Saharan deserts has started to take its toll on people their as well. Channels of water are shrinking and becoming more shallow, allowing for more drought and leading to high levels of dust in the air. This dust is carried by the north atlantic oscillation (a wind/weather pattern) to the Americas, specifically the Caribbean, where children there are experiencing higher rates of asthma and other breathing problems more than ever. Elders there don't remember anyone suffering from asthma decades ago. Not only does this Saharan dust affect the people of the caribbean, but also the sea life. This dust entering the water contains the leading cause of sea fan disease, which kills off food for fish in the sea, killing off the fish, etc etc.
 
and i get the feeling 90% of ns wont read this and will just reply "fuck global warming".... so i wont go on with more examples but........... i tried.
 
i read. haha. and i agree.

its only because you're in NSG that 90% of these ppl wont read. but the ppl who have a supported opinion will probably want to read.
 
I think I saw that movie.

Its really good i didnt see this thread when it first started 'cause it would have taken over my life....

but anyone who doesnt believe global climate change is real has never been to the arctic. it is in the fragile eco systems where the first changes are noticed.. and by god are they noticable up there. in temperate and tropical ecosystems there is enough biodiversity that the eco system is much more resillient.
 
i just watch something on the history channel about the little ice age and they sadi one possible thing is that the ocean currents that carrry warm water north are disrupted by melting ice from the artic because it is less dense fresh water. But then since warm water is not carried north, weather patterns shift and become colder, but then ice forms agian and the warm water starts flowing to the north again. then it repeats
 
Actually, the Alaskan pipeline has affected the Caribou population more than any weather related issue. The fact that people are expanding northward and logging, drilling ,etc businesses are moving further into the Yukon, AK, and such is causing the Caribou to have an off-migration pattern.

The pipeline was designed to be raised above so the caribou wouldn't notice and not change their migration paths, but they did and it fucked so much up for them. Normally, not many people know of this because it's an issue that really doesn't affect anything in our daily lives.
 
Ok well I havent read this thread yet (didnt even know it existed until now). Ill give it a thorough read over later when I have time, but to the creator of the thread, you have to use more scholarly sources. Those sources are biased (not to say there can't be bias in scholarly works, it just has more review).

For example: heritage.org is a conservative movement website. So of course they will publish reports of the falsehood of global warming because that is their internal agenda. Not the best research dude.

 
so then why did you respond and perpetuate the cycle? Its people like YOU who cause the earth to warm man, not me driving my Hummer while I club baby seals
 
petek is at Dal, and he is also in favour of this non CO2 emissions theory. so, i have yet to hear back on this theory though. you guys are saying that the accumulation of CO2 in the atmosphere is the cause of global warming, but when something as straightforward as how we put the CO2 in the atmosphere is analyzed, you can see that we are purely heating up the planet by making the CO2. the CO2 is just an indicator of how much heat we are releasing. that is the common misconception, that it is simply the effect of CO2 once it is in the atmosphere that is causing global warmning. you dont need peer reviewed journals to tell you that, because its readily available facts and simple algebra.
 
someone acknowledge what i said. i understand that all us university kids are studying for exams, but you mature high school kids might have something to say
 
yeah, population boom is really the source of all of these arguments. economic correlations to population growth aside... if there were still a billion people on earth... and they were going as we are... it wouldnt really be an issue. i dont know why people still feel the need to have 6 kids. its a lot of work and survival is only getting easier.

but on that note, with so many emerging industrial economies, its really up to us to make some technological and social changes to improve environmental conditions.
 
Dude, families are forced to have 7 kids to help share the load. If you look at almost any non-western based society, its economy revolves around agriculture. With many of these people below the poverty line, they can't afford to hire people or get everything done themselves. They need to have kids to help them out and care for them when they are dying.

It's a vicious cycle that will never change until they are industrialized.
 
jesus. do you know everything about everything? you should be nominated for the most well informed person on NS or something. Damn that was i'm being articulate tonight.
 
Oh, and of course Global Warming is real. According to An Inconvenient Truth (which i've seen and DO NOT find as biased as people claim it to be), out of nearly 200 studies on global warming, not one scientist refuted the idea that global warming is real.
 
Again, global warming is not a theory it is an observation. Scientists debate the cause of global warming.
 
The pipeline is off the ground so that it will not melt the permafrost. To the best of my knowledge the design has nothing to do with caribou migration patterns.
 
No, I didn't say the caribou was the only specific reason, but that was a factor in the engineering of it. Gotta love the history channel modern marvels. Government laws actually made them have the pipe off the ground in certain areas sensitive to caribou.
 
el_train...global warming effects many different ecosystems throughout the world..you are correct.

I am writing pretty randomly...I just finished writing an entire literature review about the subject.

Look up some peer review and actual journals if you want to know more about global warming instead of some random sites online.

I've done my homework and there is no doubt in my mind that global warming is effecting us today.

US needs to adopt a system like Sweden has...the sweden government has a tax on the global warming pollutants, and instead of the country hating it, they embraced it. by the year 2020, they will be 100% free from dependence on oil and other fossil fuels. windpower, hydro power, and biomass power are becoming more affordable. by the year 2020, the technology will be so advanced that I can't see the US NOT doing something like this. (sorry if any of this was already said...i didn't read the thread)
 
what do you mean by biomass power? burning organic matter before it has the chance to turn into oil? thats not as effective as the others, because we need a solution that doesnt have thermal pollution. thats the main problem with burning oil. when we put tjhe CO2 in the atmosphere , you can see that we are purely heating up the planet by making the CO2. if we are just releasing heat with the biofuels, then its still warming the planet. youre just taking all this potential energy in chemical bonds, energy that was once kinetic now transformed into bonds, which takes away heat. now youre turning it back into kinetic energy (also known as heating the planet). Sweden probably saves a shitload of money because they arent buying oil. Canadians harvest our own oil, so we arent as worried about the financial impact of the rising oil cost. Americans are financing all of the middle east though, so they would most likely be more open to environmentally friendly energy sources that can provide local jobs and keep their money in their own economy.

canada needs to investigate these things too. if anything, we are less worried than the US and bigger consumers per capita, because we "have to" consume so much more energy to heat our houses especially because our climate is on average 30 degrees colder.

In addition to switching to efficient energy sources that dont harm the planet, we could start reducing energy consumption. trains that are magnetically propulsed, (works on the same sort of principle as a cyclotron or a particle accelerator if you know what those are), buying bulk groceries to reduce the amount of plastic required to wrap that stuff, fluorescent light bulbs. anyone else have any crazy ideas?

also, it sounds like the swedish government can meddle in business far more than our governments can. when it comes to something like the environment, how would our government go about stepping in and forcing big business to adopt healthier habits? i mean other than financial penalties, what is there to do?
