>Passing the 400 ppm milestone in is a symbolic but nonetheless important reminder that human activities continue to reshape our planet in profound ways.
BUT SURE ! Humans are not responsible, it's the sun of course. There's no global warming, it's a false flag operation. Definitely.

so what i can do?
Zachary Baker
More government regulations and more taxes. Also shut down your factories so they can be transferred to third word countries where're they're going to pollute even more.
Good goy.
Ryan Butler
Wow didn't know they had industrialisation 4 million years ago
Daniel Green
>scientificamerican >scientific >american almost believed you

OMG 400 parts per 1,000,000 ! that's Amazing! The sky is falling!
You moron

>Antarctic CO2 Hit 400 PPM for First Time in 4 Million Years
HOW THEY COME UP WITH BULLSHIT LIKE THAT?
Easton Clark
Can you dumbass stop posting shit about CO2 level increases being bad? Have you not read any research for yourself that shows CO2 is good for plant life and ppm was on the brink of disaster prior to the industrial revolution which has helped avoid an ice age. The only issues we still face are Ozone depletion and harmful byproducts of combustion such as CO and Methane. So please, either read up or fuck off

Global warming doctrine suggests we all kill ourselves to save the planet.
Fucking hippies
Mason Powell
How did it reach that 4 million years ago?
Tyler Torres
It's a good thing those caveman scientists recorded their carbon PPM readings 4 million years ago.
William Young
Hopefully plenty of studies are being done on the true consequences of this much carbon Who knows what all it could be fucking with Sad only temps are focused on when in the past carbon has been a follower of temp increases Not a leading factor
So many other things could be thrown out of wack potentially

Lmao if not for the sun. Where do you think the heat comes from. Some people are just stupid.
Adam Sullivan
I like this post.
Robert Morris
j-just a c-coincidence
Jose Ramirez
Much warmer Neither pole had an ice cap then It's actually fairly rare for both poles to have ice sheets
Ayden Taylor
But what about 4 million years ago when there weren't any humans?
Jordan Powell
4 million years, i.e. before the start the cooling period that led to the evolution of humans
so the planet is back at a point it was at before even homonids existed.
Elijah Ward
CO2 is a coolant
Robert Richardson
Your ignorance is profound
Colton Walker
BAN ASSAULT SUN'S. AM I RITE? LMAO.
Blake Cook
The planet's core you ignorant mudslime
Alexander Harris
CO2 probably saved us from increased sun radiation.
Lincoln Carter
actually air is a non-conductor. shhh don't tell them
Hunter Gomez
The same way they come up with most of their stats. They make them up.

I've read that large scale cattle farming is a significant contributor to global warming. If we ever want to something about it we need to start by eating all the cows first. Well it might not actually save the planet, but it would be a magnificent barbecue party.
Jack Hill
i am just a civilian dude i dont have that power
Logan Williams
for all you tards wondering how they know what the antarctic atmosphere was 4 million years agp, just google ice cores
Tyler Smith
they're working on dosing cattle with marsupial gut bacteria that eats methane
Leo James
it would be easier just to nuke all of china. they surpass pretty much the rest of the world combined in polution and are debatably not even human, since they're soulless and all.
Ayden Bailey
In a near future we'll be able to "simply" grow cheap chunks of meat in a lab, that will kill large scale animal farms, and solve some of the problems they cause.

>implying Russia doesn't welcome global warming This. I'd love to see the rest of USA and western Europe there too.
Ayden Taylor
They measure layers of Ice for concentration of Carbon and also use the decay of Carbon atoms (Carbon dating) to determine the year
