[QUOTE=davethestoner;37075641]Venus doesnt have plants though.[/QUOTE] Yeah but instead it has clouds of sulphuric acid and CO2, Venus is the textbook example of a runaway greenhouse effect.
[QUOTE=ewitwins;37075128]This is a very bad thing people. This means that the CO2 absorbed by the Earth will take in more heat and bring it closer to the surface instead of the atmosphere.[/QUOTE] Uhh not necessarily. CO2 absorbed into the ocean forms CaCO3, calcium carbonate, and is eventually drawn into the mantle during plate subduction. That's where a lot of CO2 comes from during volcanic eruptions. CO2 is an organic molecule with two double bonds in it which absorb infrared radiation and then re-emit it (which is the basis of infrared spectroscopy, a technique which is used primarily for organic molecules because of their structure). CO2 absorbed into water or sitting under the mantle doesn't pose much of an issue in terms of being a greenhouse gas as it does when it's in the air because IR radiation isn't something which is so abundant in those places - heat moves primarily through convection and conduction in those environments, whereas In the atmosphere IR radiation from the sun directly, or IR radiation which is emitted from the surface of the Earth gets absorbed by gaseous CO2 and emitted back down towards the surface.
[QUOTE=download;37075147]More CO2 in the atmosphere means plants (particularly sea plants) might grow faster, meaning there is more of them, so the absorb even more CO2... Just a hypothesis[/QUOTE] I think we would've noticed if plant life on the planet had increased substantially enough to facilitate this sort of change

While it does aid in the creation of calcium carbonate (by forming carbonate), it also creates carbonic acid, leading to acidification. Like I said before, too much of a good thing, is almost always a bad thing. Honestly, we don't have much of a clue how the ocean effects the global climate. There's still loads to learn about how things are effected in the deeper levels and how the ocean's uptake of CO2 effects things on a global scale. To me, ocean acidification is the most threatening contributor to climate change.

I'm still waiting until we royally fuck up and pay for this dearly. The thought puts a smile on my face, because for me, Humanity is like one of those 'Guidos' from New Jersey who won't learn until it's too late. I hate such people [b]so[/b] much.

[QUOTE=Lazor;37076601][img]http://i.imgur.com/k53Mn.jpg[/img] we're all going to die lol[/QUOTE] Wait is this soley referring to predatory fish, as looking at the source this seems to be the case, and this surely cant be accurate... Iceland has an economy built on a fishing, and if the biomass in that area is negligent, would that not mean there is no fishing in that area? Just a question, not sure if I'm reading it wrong or something.

[QUOTE=Vollybomb;37076161]I think we would've noticed if plant life on the planet had increased substantially enough to facilitate this sort of change[/QUOTE] Not really no, what you forget to think about is the fact that plant's have multiple stages of life, and "growth" can be considered a lot of things. To give you a very vague example, take a plant nursery. Gardener's increase the amount of CO2 in the air, not to make the plants grow larger, but to allow them an increased photosynthesis, which in turn leads to greener leaves (larger amounts of mitochondria (The power plants of leaves to put it blunt)), larger harvest or better quality seeds. Size, believe it or not, can actually be very bad in the plant world, seeing as the plants I think you're talking about are product-producing plants, such as wheat, tomatoes and potatoes, aren't exactly built to become big. Rather, if they're small and bushy, they can carry a lot more offspring, which in the plant's mind is a lot better than "reaching for the sky" so to say. I can explain further however don't want to clog up the thread.
As for Iceland, they're a good example of how to fish right. (aside from fin-whaling) However we all fish from the same lake. It's going to take more than one tiny country to fix that problem.
[QUOTE=OvB;37076870]Pretty much all commercially caught fishes are predatory.[/QUOTE] Oh thank you, I was never really a fish person, nice to know that.
Humanity as a whole has to start actually doing something about it already, fuck.

Sometimes I wonder if we've already fucked our planet beyond repair, and we don't even know it yet.
[QUOTE=booster;37077079]Sometimes I wonder if we've already fucked our planet beyond repair, and we don't even know it yet.[/QUOTE] We haven't. The planet has gone through a hell of a lot worse than what's happening right now, and it has always, ALWAYS survived.

[QUOTE=JeanLuc761;37077546]We haven't. The planet has gone through a hell of a lot worse than what's happening right now, and it has always, ALWAYS survived.[/QUOTE] No doubt the planet will survive, but our planet recovering from a man made catastrophe wont happen within a fortnight. I'm just wondering if the human race would ever survive the " planetary recovery time", if we somehow managed to mess up so badly.
[QUOTE=proch;37076919]Humanity as a whole has to start actually doing something about it already, fuck.[/QUOTE] Keyword: something You can't just go around telling others to do "something". That raises a lot of questions, most importantly "What?".
I still very much believe that this is a naturally occurring phenomenon, and that humans are just speeding up the process. The historical data seems to be put to one side very easily.

I'm just wondering if the human race would ever survive the " planetary recovery time", if we somehow managed to mess up so badly.[/QUOTE] Without a shadow of a doubt there would be groups that survived, but we'd be set back by thousands - millions of years in terms of technology, and even then there's a good chance we might never recover fully.
Plant trees and shit on the roofs of buildings. I think that would help and still look cool
This is really bad. Because it means we managed to rise CO2 levels despite the Earth working MASSIVELY against it. So lets assume status quo, we effectively raised the CO2 output to times four instead of what we assumed, times 2.

yeah but CO2 is so cool. In Alien, the gas added to the big amounts of tension and atmosphere. I think this hatred of CO2 is not nice. :(
[QUOTE=davethestoner;37075641]Venus doesnt have plants though.[/QUOTE] Because the temperature eventually killed all plants(if they ever existed there), then co2 had free reign to blanket the planet even more, which is why it's at a nice 850+ degrees.
Oh look we learned something new about global warming, that means we're A: Saved! Earth is amazing! B: Fucked! Humans suck! Pick one.
[QUOTE=ewitwins;37075128]This is a very bad thing people. This means that the CO2 absorbed by the Earth will take in more heat and bring it closer to the surface instead of the atmosphere.[/QUOTE] No, its being absorbed from the atmosphere into the landmasses (aka ground). Which in turn lowers the ammount of co2 in the air. Kinda obvious. If you put some salt into a glass of water its gonna disolve at a set pace. If you put more into it, more is gonna dissolve at the same time (but in the end taking longer because there is more salt. Same with co2 and the ground. [editline]4th August 2012[/editline] [QUOTE=Lazor;37076601][img]http://i.imgur.com/k53Mn.jpg[/img] we're all going to die lol[/QUOTE] I have a really hard time believing this, and ask myself how they mesured it. Also why nobody in the fishery's has "noticed"it.
[QUOTE=Strongbad;37075577]How many times is this kind of thing going to happen before people realize that earth naturally goes through periods of climate change? The only reason people are so oversensitive about it is because of 'an inconvenient truth.' It's sort of like every other headline being related to earthquakes after a particularly big one, except a hundred times worse.[/QUOTE] You guys, it's okay. If we pretend this isn't real, it won't happen! Let's all stick our fingers in our ears and ignore everyone telling us this is a problem.
