The Ice Age

[BillyCarpenter]

There are large gaps in my education. I remember be taught about the Ice Age but I've either forgotten most of it or they didn't they didn't know back then what they know now. In any event, I'm trying to fill in those gaps in my education and what I've learned is really eye opening.


The Ice Age (and there were several) shaped not only the planet we live on but the history of mankind itself.


The big takeaway I got from learning about the ice age is that our plant experienced wild fluctuations in temperatures. We've gone thru periods where the average temps much higher than they are now. We've gone thru periods where the temps were much colder.

There other big takeaway is that "science" is very unsettled on what cause the Ice Age and what brought us out of it. There are a bunch of theories. Some think a comet crashing into the earth melted the glaciers. Others think changes to the Earth's oribit are responsible.

.
Anyway, it's a fascinating subject into science.

Re: The Ice Age

You see..you and I could have a conversation about this..You sound concerned, but not wanting to rely on Google to make a decision, you actually looked up the planets history..Indeed there have been many ice ages and alternate warming periods..The Sahara was once a lush green forest..The Earth tilts about its axis every 40K years..This can cause exaggerated seasons. There is also much we do not know about the sun and its cycles that may affect the earths climate..who knows, we may be at the beginning of another ice age..(which was shouted from the rooftops in the 60s). I'm sure deforestation is not a good thing..Polluting the environment is not a good thing, but again, I have seen no proof that this is causing more or stronger storms. My beaches still have the same high/low watermarks..Florida has been hot in the summer for more than a few years...E

I'm not concerned, I just found it so fascinating. Also, for all that science can tell us, there are still so many unanswered questions. If anything, the more I learned about the ice age, the more skeptical it made me of man-made global warming.

With recent advances in archeology through the use of technological advances such as LIDAR and GPR ancient meteor craters have been discovered and identified as dating to just before the starts of ice ages and the extinction of many prehistoric creatures.

With the crap on most network TV I find that I have been watching a lot of Discovery Channels like History Channel and Science Channel.

When I came down the the stomach flu and was laid up in bed for a week, I watched a podcast by Joe Rogan. He had a few scientists that had a spirted debate on the ice age. They all had competing theories. One was convinced that a comet was responsible for bring the planted out of the ice age. He had a lot of data to back it up. It's hard for me to go into detail about any of it because it's complicated and they used a lot of data from ice cores that were analyzed to show drastic changes to our climate.

The is a strong consensus how the universe works scientists that had a object the size of a comet had impacted the Earth, there would be no Earth. There would be another asteroid belt where the Earth now orbits.

There s also a theory out there that there have been a number of near misses within recorded history. You might want to read a few of Immanuel Velikovsky's books such as Worlds in Collision, Earth in Upheaval and Ages in Chaos.

Did a Comet Hit Earth 12,000 Years Ago?

Nanodiamonds found across North America suggest that major climate change could have been cosmically instigated



Roughly 12,900 years ago, massive global cooling kicked in abruptly, along with the end of the line for some 35 different mammal species, including the mammoth, as well as the so-called Clovis culture of prehistoric North Americans. Various theories have been proposed for the die-off, ranging from abrupt climate change to overhuntingteensy diamonds, which only occur in sediment exposed to extreme temperatures and pressures, such as those from an explosion or impact, according to new research published today in Science.

The discovery lends support to a theory first advanced last yearMilankovitch cycles) that continues today. And it remains an unexplained anomaly in the climate record.


But a series of cometary fragments exploding over North America might explain a layer of soil immediately prior to the cooling containing unusually high levels of iridiumasteroid impact that wiped out the dinosaurs 65 million years ago. "This is an event that happened on one day," Kennett notes. "We're going to need high-resolution climate records, archaeological records, paleontological records to try to explore the effects."

I have read that Jupiter uses it's gravity to help deflect objects away from the earth. Very interesting.
