Earth Becomes a Snowball...AGAIN?
Harvard ^ | 1999 | Hoffman

Posted on 12/17/2009 10:11:27 AM PST by Huebolt

Could the Earth become a "snowball" in future? For the last million years, the Earth has been in its coldest state since the Neoproterozoic. We are now living in a relatively warm episode, some 80,000 years from the next glacial maximum, but some evidence suggests that each successive glaciation over the last several cycles has been getting stronger and stronger. During the most recent glacial event, 20,000 years ago, the deep ocean cooled to near its freezing point, and sea ice reached latitudes as low as 40 to 45 degrees north and south, still far from the critical threshold needed to plunge the Earth into a snowball state. But could such a state be in our future? Certainly over time scales of hundreds to thousands of years, we are more concerned with anthropogenic effects on climate, as the Earth heats up in response to emissions of carbon dioxide. But only time will tell where the Earth’s climate will drift over millions of years. If the trend of the last million years of Earth history is continued and if the polar continental "safety switch" were to fail, we may once again experience a global ice catastrophe which would inevitably jolt life in some new direction. Perhaps Robert Frost foresaw this in his poem, "Fire and Ice":

Here's a video that goes over the past 400,000 years and the interglacial periods: Global Cooling.

No it isn't, and we shouldn't. It was as warm or warmer in 1000 AD than it is today. That's a scale of a mere thousand years and the AGW theory can't explain that.

I live near Raleigh,NC. This weekend it's supposed to be cold with rain or snow. For the third weekend in a row, I won't get to golf. I think I'll write my Senator Kay Hagin (D) about this catastrophe.

“as the Earth heats up in response to emissions of carbon dioxide”

Is there any RELIABLE evidence that the Earth is heating up?
NO
Is there any RELIABLE evidence that the Earth is heating up in response to emissions of carbon dioxide?
NO

Is the Earth getting colder? YES

How do I know that?
A good guess since I am currently sitting about 100 yards from the Black Sea, its about 0 degrees f, we had a blizzard that knocked out power in most of Southern Ukraine and put over a foot of snow on the ground, and I froze my butt last night with no heat AND everyone here says its the first time in anyones memory that this has happened here in the middle of December.

Al Gore is a fraud who needs to be in Prison.

An excellent VIDEO. I’ve seen it before and I highly recommend you send it to any global warming believers if you know them. I certainly know them.

Absolutely! The guy is a much bigger scam artist than Bernie Madoff. In fact Madoff is small time compared to Gore. They ought to be sharing the same cell.

“I am currently sitting about 100 yards from the Black Sea”

What are you doing there?

See 2 above for an even better presentation. Geological epochs have mostly standardized interpretations that change very slowly.

Oh, I am just a crazy retired expat exploring Eastern Europe.
Actually I sell private and commercial jet aircraft also but since the financial crisis that has not been by any means full time..wish I could say that is funny but considering the current state of my wallet it is not.

Interesting. Stay warm.
Maybe you should explore parts further south this time of year!
The Black Sea and December, just sounds like a really cold combination!

>>Perhaps Robert Frost foresaw this in his poem, “Fire and Ice”

From memory:

Some say the world will end in fire
Some say in ice
From what I’ve tasted of desire
I hold with those who favor fire

But if it had to perish twice
I think I know enough of hate
To say that for destruction
Ice is also great, and would suffice

“Certainly over time scales of hundreds to thousands of years, we are more concerned with anthropogenic effects on climate, as the Earth heats up in response to emissions of carbon dioxide. But only time will tell where the Earth’s climate will drift over millions of years.”

1) Temps. seem to rise about 800 years BEFORE the CO2 levels rise.

2) Regardless, manmade CO2 only accounts for about 0.118% of the greenhouse effect.

3) The last interglacial warm period lasted about 13,000 to 15,000 years. We are on about year 12,000 for our current warm period. (Note: Past results are no guarantees of future events.)

If this looks like it really would happen we could try terraforming - open a sea lane through the Isthmus of Panama. Some people think it's closure is what caused the Quaternary.

I used to think all the catastophe theory hysteria was due to the illusion of central position wherein each generation has that certainty that times are different because WE ARE HERE and that the world will surely end before we do.

There were maniacal cults about armageddon, end-of-millenium, etc. Global cooling looks like the real thing.

I remember standing on a hill in west Texas and looking in disbelief at GLACIAL STRIATION MARKS left there during the last ice age. That's way, way south...
