Climate change: Arctic passes 400 parts per million milestone

Arctic monitoring stations show carbon dioxide levels are now above 400 parts per million. Carbon dioxide is the chief climate-change gas and stays in the atmosphere for 100 years. Before the Industrial Age, carbon dioxide levels were 275 ppm.



The world's air has reached what scientists call a troubling new milestone for carbon dioxide, the main global warming pollutant.
Monitoring stations across the Arctic this spring are measuring more than 400 parts per million of the heat-trapping gas in the atmosphere. The number isn't quite a surprise, because it's been rising at an accelerating pace. Years ago, it passed the 350 ppm mark that many scientists say is the highest safe level for carbon dioxide. It now stands globally at 395.

So far, only the Arctic has reached that 400 level, but the rest of the world will follow soon.



"The fact that it's 400 is significant," said Jim Butler, global monitoring director at the National Oceanic and Atmospheric Administration's Earth System Research Lab in Boulder, Colo. "It's just a reminder to everybody that we haven't fixed this and we're still in trouble."

Carbon dioxide is the chief greenhouse gas and stays in the atmosphere for 100 years. Some carbon dioxide is natural, mainly from decomposing dead plants and animals. Before the Industrial Age, levels were around 275 parts per million.

For more than 60 years, readings have been in the 300s, except in urban areas, where levels are skewed. The burning of fossil fuels, such as coal for electricity and oil for gasoline, has caused the overwhelming bulk of the man-made increase in carbon in the air, scientists say.

It's been at least 800,000 years — probably more — since Earth saw carbon dioxide levels in the 400s, Butler and other climate scientists said.

Until now.

Readings are coming in at 400 and higher all over the Arctic. They've been recorded in Alaska, Greenland, Norway, Iceland and even Mongolia. But levels change with the seasons and will drop a bit in the summer, when plants suck up carbon dioxide, NOAA scientists said.

So the yearly average for those northern stations likely will be lower and so will the global number.

Globally, the average carbon dioxide level is about 395 parts per million but will pass the 400 mark within a few years, scientists said.

The Arctic is the leading indicator in global warming, both in carbon dioxide in the air and effects, said Pieter Tans, a senior NOAA scientist.

"This is the first time the entire Arctic is that high," he said.

Tans called reaching the 400 number "depressing," and Butler said it was "a
 
Matthew, make sure you come around and post in reply to my OPs and comments, at this and other threads, since we are bound to see a flock of skeptic geeks come around, to try to hijack this thread.

You will see quote in quote in quote, with propaganda, and you will see my comments, about carbonic acidification and re-greening, which are all over threads like this one, just from one week of USMB.

Acidification is going to get worse, and then we will face collapse, of the oceanic food chain. Re-green, or die!
 
I'll be darned. The skeptics aren't responding, to this post. I guess they can't argue, with 400 ppm atmospheric CO2, all the way, from 275 ppm CO2, in the 19th Century.

Something needs to get done, yesterday, for instance re-greening and CO2-neutral biomass, both.

We have got to get those polar bears to stop driving SUV's.
 
Carbon dioxide is the chief climate-change gas and stays in the atmosphere for 100 years.
Unless, of course, it gets absorbed by the flora of the Earf prior to that time.
Before the Industrial Age, carbon dioxide levels were 275 ppm.
Correlation still doesn't equal causation, no matter how many times you try to say it does.
You forgot how methane is being released, to accelerate warming, since the first quote is not mine. You forgot how 350 ppm CO2 is the maximum safe level, and the Arctic is at 400 ppm, now, since you got the 2nd quote from me.

Causation of warming phenomena is partly human. Relief and remedy are 100% human responsibility. You are dumb as shit. Quit selectively quoting and fucking up replies.

Have you ever heard of Weather Cycles?
 
Have you ever heard of Weather Cycles?
Have you heard of carbonic acidification, killing plankton, eggs, little fish, oysters, reefs, and next comes the oceanic food chain? Have you heard of the release of sequestered methane, which will result in the hockey stick acceleration, of warming?

Have you heard the extinction rate is over 100 times normal, headed for 1000 times normal? Have you heard of the 5 Mass Extinction Events? Do you know we can get to 6?

None of which points to any causation.

Says you, dickweed.

If I can instantly pull two glaring logical flaws straight off the top of the deck, it's a waste of time to wade through the rest of the warmer cultist drivel.

One, you are dumb as shit. Two, you took the names off the quotes, and you quoted incompletely. Three, you have shit for brains, so you are dumb as shit. Four, if you fucked up the quotes, you didn't find any flaws, shithole. Five, you are a fucktard, in a fucktard clusterfuck. You shouldn't have been spawned, but I couldn't get to the tardfarm in time, to stop Dr.DDD, from filling the test-tube.

CO2 is around 400 ppm. It was 275 ppm, at the start of the industrial age. For Liability, 350 ppm is the subject of research, as the upper safe limit:

Humans didn't develop under co2 levels higher than 400 ppm as the last time it was this high is around 10-15 million years ago. Was their life on this planet, yes, but not complex life like us that use the environment around us to survive(farming, water, etc)...

Our form of doing things hasn't been tested in such an environment. We will survive, but things might not be comfortable as they're now.

Aside from a gang of kook warmist cult members, who says 350 ppm is the maximum safe level?

No, 350 ppm is a a totally gratuitous number conjured up by the global warming cult purely for political purposes. It has no scientific basis. None.

Matthew, you do realize, don't you that CO2 enhances plant growth so your argument that more CO2 might harm farming is an invalid point. And again, it has been warmer and those warm periods were very good for civilization. Historically, it is the cold periods that cause us the most problems.
