World carbon dioxide levels highest for 650,000 years, says US report - PolitiCity
Well... I hope y'all are ready for a wild ride...
Cuz I fear we are due for one...
And you know...
It's amazing what the scientists who are NOT corporate shills have to say about the state of our environment.
World carbon dioxide levels highest for 650,000 years, says US report
· Rise in chief greenhouse gas worse than feared
· Earth may be losing ability to absorb CO2, say scientists
David Adam, environment correspondent The Guardian,
Tuesday May 13 2008
The concentration of carbon dioxide in the atmosphere has reached a record high, according to the latest figures, renewing fears that climate change could begin to slide out of control.
Scientists at the Mauna Loa observatory in Hawaii say that CO2 levels in the atmosphere now stand at 387 parts per million (ppm), up almost 40% since the industrial revolution and the highest for at least the last 650,000 years.
The figures, published by the US National Oceanic and Atmospheric Administration on its website, also confirm that carbon dioxide, the chief greenhouse gas, is accumulating in the atmosphere faster than expected.
The annual mean growth rate for 2007 was 2.14ppm - the fourth year in the last six to see an annual rise greater than 2ppm.
From 1970 to 2000, the concentration rose by about 1.5ppm each year, but since 2000 the annual rise has leapt to an average 2.1ppm.
Scientists say the shift could indicate that the Earth is losing its natural ability to soak up billions of tonnes of CO2 each year.
Climate models assume that about half our future emissions will be reabsorbed by forests and oceans, but the new figures confirm this may be too optimistic.
If more of our carbon pollution stays in the atmosphere, it means emissions will have to be cut by more than is currently projected to prevent dangerous levels of global warming.
...snip
A study last year suggested that the recent surge in atmospheric CO2 levels was down to three processes: growth in the world economy, heavy use of coal in China, and a weakening of natural "sinks", forests, seas and soils that absorb carbon.
The scientists said the increase was 35% larger than they expected.
...snip Larger than expected rises...
More carbon dioxide in the atmosphere than has been there for 650,000 years...
This does not bode well for our civilization, such as it is...
Nay, this does not bode well at all...
Got uhhhh, spaceship?

Hmmm... what happened to the corporate spokesmen that used to inhabit this site?
They seem to be strangely quiet...
I wonder why...
Is it the irrefutable sources I've given them?
I doubt it, most righties have no trouble at all disputing facts with illogical discourse...
As I'm sure you out there who are viewing but not posting have seen elsewhere.
waves to the lurker...

Lol, Stripey.
No one ever refuted that CO2 is higher than its ever been.
Let's continue trying to reduce it.
I'm all for it.

I'm all for it. Not that it's ever been, just higher than it has been in hundreds of thousands of years.
What I would and will dispute is whether or not atmospheric global warming exists, how bad it is if it does, whether or not it will harm the environment, or whether or not any information that disputes the global warming fanatic's claims is 'industry-sponsored crap'.

Sorry, my mistake.

NC is enjoying our coolest spring on record in decades!
:-)
Just a minor point to make in regard to carbon dioxide levels- There are more people populating the earth....
I read an article last week where a liberal proposed caps on life.
Gee, there's a great idea!
Who will be the first person to voluntarily die sooner, raise your hand please!

You can't just say that because your area is cooler, global climate change isn't occuring.
And a coolest spring in decades would be a changed climate anyway, although the overall trend is warming.
My area had one of the warment winters on record, and we had a minimal 2 total inches of snow compared to the annual average of 26, and I believe those 2 inches is the record in our area for least snowfall in a full year.
We didn't even get any snow days (we did get a power outage day, though, lol).
And of concern of the CO2 levels, the ozone is getting thinner, whether it's climate change or not.
Where did you read that;
I have to see it to believe it.
I'm guessing he was being sarcastic.
If he wasn't, he's an idiot.
Anyway, overpopulation is going to be a huge problem;
Not enough food, not enough jobs, not enough leg room.
I'm not going to suggest dieing at a certain age (althouh you do have to die in Futurama at age 160, lol), nor am I going to suggest a cap on how many children you can have, because that has some bad repercusions, in addition to being unfair.
Overpopulation is something we're going to have to deal with, though, since there are no predators, other than ourselves, to limit our population.

I don't understand why you think the climate isn't supposed to change.
According to your logic, we should never have any record temperatures, low or high.
It should always sit around some predetermined "average."
Also, I don't even see how people can call what we are experiencing a "trend." In the global cooling thread, I remember quoting NASA that temperatures have only increased 0.4~0.8 degrees C over the last 200 years.
And then people try to be tricky and claim that this "trend" is "faster" and "more severe" than past trends.
That's BS. According to NASA, "Many experts estimate that the average temperature will rise...[at a rate] much larger than most past rates of increase" (emphasis added).[1] And I have yet to see any explanations for these "estimations," save for an icrease in CO2, which would be a fallacious explanation nonetheless.
As for overpopulation, according to The National Center for Policy Analysis (NCPA), "[i]f the entire population of the world were put into the land area of Texas, each person would have an area equal to the floor space of a typical U.S.
Home and the population density of Texas would be about the same as Paris, France."[2]

I was saying to Tatianna that just because North Carolina had a cooler year than normal, it doesn't mean that: 1) there is no climate change, 2) that everywhere is cooler.
I agree, it should never be exactly average, and there are high and low trends.
However, I think that the CO2 levels are producing an abnormal trend of warmpth and ozone degradation.
Assuming the earth was created 4.6 billion years ago, we are the first unchallenged, tertiary predator in history, and we are multiplying uncontrollably.
We may all fit into Texas, but eventually there will be too many people for jobs and food.
However, when we reach that point, the food-less and job-less will die out and the population will stay in relative equilibrium, assuming the ozone doesn't explode, Greedland doesn't melt, and we all don't run out of oxygen.

Okay, but then that seems like a tautology.
There is no "global trend" occuring.
Some parts of the world are having record highs, some are having record lows.
Some are experiencing rather average temperatures.
Etc, etc. There's no "abnormal trend" you can point to, BassPlayer.

Well, I don't want to go too far into this, but I think we can rest assured that we aren't going to uncontrollably overpopulate the earth anytime soon.
Especially with technology advancing, allowing us to produce more food using less land, and for cheaper prices.
