Earth On The Brink Of An Ice Age

The earth is now on the brink of entering another Ice Age, according to a large and compelling body of evidence from within the field of climate science. Many sources of data which provide our knowledge base of long-term climate change indicate that the warm, twelve thousand year-long Holocene period will rather soon be coming to an end, and then the earth will return to Ice Age conditions for the next 100,000 years.
Ice cores, ocean sediment cores, the geologic record, and studies of ancient plant and animal populations all demonstrate a regular cyclic pattern of Ice Age glacial maximums which each last about 100,000 years, separated by intervening warm interglacials, each lasting about 12,000 years.
Most of the long-term climate data collected from various sources also shows a strong correlation with the three astronomical cycles which are together known as the Milankovich cycles. The three Milankovich cycles include the tilt of the earth, which varies over a 41,000 year period; the shape of the earth’s orbit, which changes over a period of 100,000 years; and the Precession of the Equinoxes, also known as the earth’s "wobble," which gradually rotates the direction of the earth’s axis over a period of 26,000 years. According to the Milankovich theory of Ice Age causation, these three astronomical cycles, each of which effects the amount of solar radiation which reaches the earth, act together to produce the cycle of cold Ice Age maximums and warm interglacials.
Elements of the astronomical theory of Ice Age causation were first presented by the French mathematician Joseph Adhemar in 1842, it was developed further by the English prodigy Joseph Croll in 1875, and the theory was established in its present form by the Serbian mathematician Milutin Milankovich in the 1920s and 30s. In 1976 the prestigious journal Science published a landmark paper by John Imbrie, James Hays, and Nicholas Shackleton entitled "Variations in the Earth's orbit: Pacemaker of the Ice Ages," which described the correlation which the trio of scientist/authors had found between the climate data obtained from ocean sediment cores and the patterns of the astronomical Milankovich cycles. Since the late 1970s, the Milankovich theory has remained the predominant theory to account for Ice Age causation among climate scientists, and hence the Milankovich theory is always described in textbooks of climatology and in encyclopaedia articles about the Ice Ages.

Global claimate change
Global Bush's Fault!
GLOBAL WARMING IS COMMING!!!
Ok, so it’s in 100,000 years...
LMAO!!!!!!!!!
A new ice age would really hit some DemocRAT strongholds pretty hard.
So I have a good excuse to go out and buy a couple of snowmobiles?

I am aware that we are talking about Pravda here, and it has the historical baggage of the meaning of "truth" in Russia.
Having said that, ignorance is no excuse even for Russians. Their scientists today are more ethical and robust than their Western counterparts, particulaly in the area of "Global Warming." And yet, they seem to unaware of an "Inconvenient Truth" about climate that is scientifically undisputable :
We are in an interglacial period, one of many the earth has experienced in the last 400,000 years.
Nothing "Brink-y" about it!
Gheeeeez!
No this is different. Here we have history and regular cycles that reoccur that have been documented. We WILL enter a new ice age - the only question is when.
I’ll believe it when James Hansen jumps on board.....He’s the climate whore who’s made a fortune out of the past ice age hoax, the current GW hoax and most likely the new ice age hoax.......
Great. I invested so much into a warm weather wardrobe, now I’ll have to exchange it for a cold weather one.
“The graph of the Vostok ice core data shows that the Ice Age maximums and the warm interglacials occur within a regular cyclic pattern, the graph-line of which is similar to the rhythm of a heartbeat on an electrocardiogram tracing. The Vostok data graph also shows that changes in global CO2 levels lag behind global temperature changes by about eight hundred years. What that indicates is that global temperatures precede or cause global CO2 changes, and not the reverse. In other words, increasing atmospheric CO2 is not causing global temperature to rise; instead the natural cyclic increase in global temperature is causing global CO2 to rise.
The reason that global CO2 levels rise and fall in response to the global temperature is because cold water is capable of retaining more CO2 than warm water. That is why carbonated beverages loose their carbonation, or CO2, when stored in a warm environment. We store our carbonated soft drinks, wine, and beer in a cool place to prevent them from loosing their “fizz,” which is a feature of their carbonation, or CO2 content. The earth is currently warming as a result of the natural Ice Age cycle, and as the oceans get warmer, they release increasing amounts of CO2 into the atmosphere.
Because the release of CO2 by the warming oceans lags behind the changes in the earth’s temperature, we should expect to see global CO2 levels continue to rise for another eight hundred years after the end of the earth’s current Interglacial warm period. We should already be eight hundred years into the coming Ice Age before global CO2 levels begin to drop in response to the increased chilling of the world’s oceans.”
Now’s our chance to sell refrigerators to the Eskimos.
Quick...drill for oil, and buy Hummers.
If this happens, we can kiss ANWAR and the rest of the North Slope goodbye.
