CO2 levels pass 400ppm for the first time in 3-5 million years - Polidicks

[img]http://imgkk.com/i/5kb7.jpg[/img] [url]http://www.bbc.co.uk/news/science-environment-22486153[/url] [quote]Carbon dioxide levels in the atmosphere have broken through a symbolic mark. Daily measurements of CO2 at a US government agency lab on Hawaii have topped 400 parts per million for the first time. The station, which sits on the Mauna Loa volcano, feeds its numbers into a continuous record of the concentration of the gas stretching back to 1958. The last time CO2 was regularly above 400ppm was three to five million years ago - before modern humans existed.[/quote]

gg humans

In your face, nature!

well fuck :suicide:

[QUOTE]The last time CO2 was regularly above 400ppm was three to five million years ago - before modern humans existed.[/QUOTE] No see that's fine because there was so much lush vegetation and large animals back when dinosaurs roamed the prairie, so everything's good and nothing is wrong. Do not doubt the power and wisdom of the carbon overlords.

It's been measured at a one-time point above 400ppm in our time. Back 5 million years ago, 400ppm was the norm.

Everyone stop fucking breathing so much jesus christ guys [editline]10th May 2013[/editline] I bet there's people reading this post RIGHT now and breathing fuckers

400ppm is really nothing.

I get the feeling that the facility being on top of a volcano also has something to do with it

[QUOTE=Killer900;40596442]You say that as if there's nothing to worry about.[/QUOTE] It is something to worry about. But this doesn't mean that current levels are at 5 million years ago levels; just that the top measurement is 5 million years ago level. Of course it's a cause of concern still.

[URL="http://www.esrl.noaa.gov/gmd/obop/mlo/programs/esrl/volcanicco2/volcanicco2.html"]They monitor the volcano specifically[/URL] in addition to the atmospheric shit and then account for the former in measurements of the latter.

Now we can only hope someone invests more time and money into researching those algae that eat CO2 and shit biodiesel.

Lets take into account that they are measuring this on the side of a volcano.

[QUOTE=smurfy;40596528]Lol yh nothing at all[/QUOTE] I think he's just saying relative to what the Earth has been in the past. If I remember correctly, it used to be ~7,000ppm around the time of the dinosaurs, which is pretty damn extraordinary to think about. That's right on the edge of being toxic for us :v:

[QUOTE=areolop;40596550]Lets take into account that they are measuring this on the side of a volcano.[/QUOTE] oh jeez you're right alright guys, global warming panic over everyone go home man why did we do all of our calculations from VOLCANOES jeez

[QUOTE=smurfy;40596528]Lol yh nothing at all [img]http://imgkk.com/i/t-k1.gif[/img][/QUOTE] ya but that chart is kinda bad, it only represents ranges between 270 and 400 ppm, so of course a rise in ppm would show a massive spike here's to packing our collective bags and heading to mars

Sweet, more gas for my paintball gun! :downs:

[QUOTE=nox;40596588]Sweet, more gas for my paintball gun![/QUOTE] solution found, everyone should get paintball guns

[QUOTE=Sableye;40596579]ya but that chart is kinda bad, it only represents ranges between 270 and 400 ppm, so of course a rise in ppm would show a massive spike here's to packing our collective bags and heading to mars[/QUOTE] the atmosphere on mars is already 96% CO2, nothing for us to fuck up!

Yes! We did it boys!

[QUOTE=Sableye;40596579]ya but that chart is kinda bad, it only represents ranges between 270 and 400 ppm, so of course a rise in ppm would show a massive spike[/QUOTE] well a rise from 270 ppm to 400 ppm would be pretty significant so I don't know what your point is

Let's poke a hole in the ozone layer, get some big fans, and blow all the CO2 into space.

[QUOTE=Mad Chatter;40596636]Let's poke a hole in the ozone layer, get some big fans, and blow all the CO2 into space.[/QUOTE] can't do that I'm afraid all the gravity would escape too and last time that happened boy was it grim

Just so you guys know, average CO2 for the past hundreds of thousands of years was 280 ppm [I]max[/I], and 180 ppm minimum. The levels would change over long periods of time, too. And before the Industrial Revolution, we were within those levels. So basically, in the past 200 years or so we've gone more than a full amplitude above normal. 400 parts per million seems small, but it's the second largest greenhouse gas in the atmosphere. Most of the atmosphere doesn't affect heat levels, and seemingly small differences in atmospheric gas levels can actually have big effects. It is true that methane is a much more powerful greenhouse gas than CO2, but there's also about 200 times less of it, which is a large enough difference so that methane as a whole isn't stronger than CO2. The most powerful and largest greenhouse gas, however? H2O. We're not worrying about releasing H2O into the atmosphere, however, because of something called [I][B]the water cycle[/B][/I]. You know, elementary school level stuff. H2O doesn't work as a forcer, but instead only increases or decreases in response to other greenhouse gases, creating a feedback loop. That's one reason why small changes in CO2 and other greenhouse gases are more important than they seem, they indirectly affect H2O levels. Note: some of my stuff may be a bit off, I'm working mostly from memory here. Someone tell me if I've messed something up.

Do not doubt the power and wisdom of the carbon overlords.[/QUOTE] The dinosaurs were already extinct 5 million years ago, and many people think they went extinct exactly because of higher CO2 levels. Huge animals like the T-rex or sauropods needed an atmosphere rich in oxygen
