Tiny bubbles, rising seas point to warming

WASHINGTON - Ocean and so-called greenhouse gas levels are rising faster than they have for thousands of years, according to two sea and ice core studies published Thursday in the journal Science.

The ice core study examined tiny air bubbles trapped in ice to determine that the atmosphere has much more carbon dioxide - a gas that many scientists tie to global warming - than at any point during the last 650,000 years.

The ocean study found Earth's sea levels have risen twice as fast in the past 150 years, signaling the impact of human activity on temperatures worldwide, researchers said.

Sea levels were rising by about 1 millimeter (0.04 inches) every year about 200 years ago and as far back as 5,000 years, geologists found from deep sediment samples from the New Jersey coastline. Since then, levels have risen by about 2 millimeters (0.08 inches) a year.

"We believe the ice sheet was not around all the time. It was only around during cool snaps of the climate," Miller said.

"There's no natural condition that we know about in a really long time where the greenhouse gas levels were anywhere near what they are now. And these studies tell us that there's a strong relationship between temperature and greenhouse gases.

I guess maybe they should look back a bit further, like maybe those times before the artic ice was formed....but that's right, the earth is only 650,001 years old, right?

The only bubbles are those in the eco nuts brains...

I find it interesting that the enviros elevate evolution to a near-religion, but appear to think the earth should be immutable. How do they think all that evolution happened? Drastic climate change was going on long before man arrived on the scene.

I have seen nothing that puts the 2 groups together.

apart from them both being sciences under attack by politics.

I don't mind posting this link over and over...

It demonstrates that Global Warming is REAL and has been for hundreds of thousands of years... between periods of Global Cooling.

[freedumb2003]

Soo true.

[Cleburne]

Besides, last time I checked man is part of the biomass of the planet. And since man is just another element in the evolutionary line, and biological development is amoral, why should any of this be a cause for concern? Are we supposed to legislate morality for the course of evolutionary development? And what's with science making value judgments? Where did they get that authority?

[roaddog727]

"...signaling the impact of human activity on temperatures worldwide, researchers said."

And just how did these scientists ascertain that human activity is the culprit for this temperature rise?

Perhaps this could have something to do with the sun and heat, and cyclic natural heat increases.

[T'wit]

Ya gotta wonder about people who go burrowing deep into the sediment of New Jersey.

[freedumb2003]

Taking partial data as a whole (lying) is a hallmark of the Left.

I hope the Lefties are really, really happy that their beloved "working poor" (their term, not mine) can't afford gasoline in Calfornia because of the special formulation that no other state needs and has no basis in real science.

Me? I tank up whenever I need or want to and could do so even if they doubled gas prices again.

[BipolarBob]

Don Ho warned of this very thing many years ago.

[WBL 1952]

Of course there is more Carbon Dioxide in the air today than before: nobody was popping beer tabs 650,000 years ago.

I have seen nothing that puts the 2 groups together. You have a point; but my gut feeling is that, while not all evolutionists are environmental wackos, I believe that virtually 100% of environmental wackos are evolutionists. So it seems natural to criticize the environmental wacko on the basis of this inconsistency: while change is an evolutionary axiom, much of it brought about by environmental change, they hold that any further environmental or species changes must be prevented at all costs.

Within that context, your point is well-made. I agree it is difficult to picture an enviro-whacko creationist.

[bobdsmith]

good point

[Paloma_55]

the real kicker is that this data is scientific, pulled from ice cores in Antartica and indisputable. There is absolutely no debate that the world has experienced a cyclic thermal variation as measured in those core samples.

Where the debate *could* exist, is what human generated CO2 will do to the situation, but I believe that the likely result would be thermal stabilization.

If you read the website, there is clear tracking between CO2 and thermal variation, but what they also talk about is a feedback mechanism that causes oscillation and what they do not really know is whether CO2 production (natural) causes the cycling, or if thermal variation causes the CO2 production.

Only the scientific papers that can be portrayed as alarming get picked up by the MSM. The moderate ones never see the light of day.
