BAD NEWS AND GOOD NEWS
The coming of the glaciers in 2018 will forebode extreme times that will change the face of our world. Every eco-system on Earth will undergo change and many of the species that we catalog today will simply cease to be.
E.O. Wilson will be mad.
Big deal. A bigger deal is the attendant drop in the atmospheric CO2 ppm count. In the last Glacial Period carbon dioxide atmospheric levels dropped to 152 ppm, embarrassingly close to the count (126 ppm) where all carbon based life becomes unsustainable
Now wouldn't that be a bummer.
But there is good news! Who knows what manner of rough beast will slouch out from this new age Ice Age? We ourselves were birthed by the environmental demands of the last Ice Age and we turned out grand. We became acculturated apes who dance upon the moon. Not bad considering our lowly origins, don't you think?
And while you are thinking, think of the opportunities to make a fast buck in real estate. With 10% of the Earth's water frozen as ice at the caps sea level will drop 300 feet increasing the continental land area by 10%. Great, but enough good news... let's talk about caves.
CAVING IN TAG DURING THE ICE AGE
In 2018 the temperature inside TAG caves will be about 42 degrees F. Thick blankets of snow will accumulate in the Cumberland Plateau during the long winter, then - at once - the snow will melt in a torrent of flooding in a late Jule spring.
Most water tables will drop tens of meters under these conditions of fast river entrenchment and very few new caves will be created.
These conditions will remain just so for about 100,000 years.
Exploring Ice Age caves might get crowded as all sorts of wild ignorant creatures might seek to escape the deep cold by hiding in caves...not to mention wild animals.

World Temperatures according to the Hadley Center for Climate Prediction. Note the steep drop over the last year.Twelve-month long drop in world temperatures wipes out a century of warming*

Over the past year, anecdotal evidence for a cooling planet has exploded. China has its coldest winter in 100 years. Baghdad sees its first snow in all recorded history. North America has the most snowcover in 50 years, with places like Wisconsin the highest since record-keeping began. Record levels of Antarctic sea ice, record cold in Minnesota, Texas, Florida, Mexico, Australia, Iran, Greece, South Africa, Greenland, Argentina, Chile -- the list goes on and on.
No more than anecdotal evidence, to be sure. But now, that evidence has been supplanted by hard scientific fact. All four major global temperature tracking outlets (Hadley, NASA's GISS, UAH, RSS) have released updated data. All show that over the past year, global temperatures have dropped precipitously.
A compiled list of all the sources can be seen here. The total amount of cooling ranges from 0.65C up to 0.75C -- a value large enough to wipe out nearly all the warming recorded over the past 100 years. All in one year's time. For all four sources, it's the single fastest temperature change ever recorded, either up or down.
Scientists quoted in a past DailyTech article link the cooling to reduced solar activity which they claim is a much larger driver of climate change than man-made greenhouse gases. The dramatic cooling seen in just 12 months time seems to bear that out. While the data doesn't itself disprove that carbon dioxide is acting to warm the planet, it does demonstrate clearly that more powerful factors are now cooling it.
Let's hope those factors stop fast. Cold is more damaging than heat. The mean temperature of the planet is about 54 degrees. Humans -- and most of the crops and animals we depend on -- prefer a temperature closer to 70.
Historically, the warm periods such as the Medieval Climate Optimum were beneficial for civilization. Corresponding cooling events such as the Little Ice Age, though, were uniformly bad news.
