GGG Ping?
Just curious, I’ve never seen any indication that Australia was ever affected by an ice age. But I don’t really know, one way or another. Anybody out there know anything?
The biggest difference was that you could have walked to what became Papua New Guinea and Tasmania.
Though I don’t hear anyone complaining about the global warming that wiped out all that land, and when sea levels rose about 300 feet.

Thanks Blam. There was at least one event analogous to the glacial lake flood that produced the Channeled Scablands. |

The entire drainage system in Russia has been reversed several times during the past 130 000 years.If so, then the living environment changed along with it, which means there were various ecosystems according to those reversals. There seems to have been a dramatic impact of the Western/Central Asian rivers and lakes and seas upon the flow of time and life around it. Mankind's journey would be much marked by these influences.
That said, those same reversals would have occurred throughout earth's long history. How did they impact the planet's life prior to man's arrival to Asia? For example, we laymen tend to think of the age of dinosaurs as static. Clearly the climate was not, so, neither was animal life.

A geologic study with major climatological implications. And there is no apparent effort on the part of the scientists to practice anything other than science.
One would think that everybody in Norway would be praying for evidence of 'global warming'...
They do this by driving around on the ground? Sounds as if they have never heard of LIDAR...
"The scientists are also investigating the landscape around the river, searching for old, dry valleys and small depressions that may explain the drainage system. After driving for just a couple of hours and walking a bit in the forest, they find small valleys which drained into the present course of the river."
If you look up the farthest reach of the ice sheets in the northern hemisphere during previous ice ages, they never got farther south than about 39 degrees north latitude. It just so happens that the southernmost point of Australia is also about 39 degrees from the equator. So if ice sheets were of equal extent in the southern hemisphere, they would not have covered any significant amount of land in Australia.
The past few million years were notable for the Quarternary ice age. There were many glacial and interglacial periods (over 20) during this time, the last glacial about 20,000 years ago. In Tasmania there is evidence of three different glaciations-the last glaciation, one sometime in the Quaternary, and one in the Tertiary. In mainland Australia, there is evidence of only the last glaciation, and the ice then covered only 25 square kilometres, in the vicinity of Mt Kosciuszko...
According to Wikipedia, Antarctica and Australia started separating 80 million years ago. I think when most people speak of ice ages they are referring to various cycles in the last few hundred thousand years, although apparently these are just parts of a an extended modern ice age that began 40 million years ago and which is still continuing.

I wonder if one of these reversals and consequent flooding along with catastrophic rain (for example from the explosion and dust of Mt. Mazama about 7600 years ago), could have caused the biblical flood story?
