Geography of the Ice Age – Fantastic video!

This guy has really done his homework! I especially like that he shows how much larger the landmasses became when sea levels were 130 meters (426 feet) lower than today. (This part of the video begins at about 7½ minutes in.) This a cogent reminder that many ancient cities are almost certainly buried beneath layers of mud and sediments that have accumulated over the eons.

  1. slight issue
    the glaciers DID reach mainland aus not just Tasmania because we have the wide flat rockstrewn gougesleft BY glaciers down sth in Sth Aus
    always go blank on the name of the area but we were taken there on a school excursion to see it

  2. Another point is that landscape is NORMAL for the majority of the time frame for the for the last 1 million years apart from 60,000 years of interglacial in that period, but still retaining a major Ice Cap at or both poles in the Time frame.
    Interglacial are an periodic accident of Solar Induced Warming and orbital/procession of the Earth being in the right place at the right time which usually conspire every 140K years to start the process.

  3. Amazing – thanks much.

    I think I’ve posted these two around a few times:

    Advance and retreat of the Alpine glaciers during the last glacial cycle

    Most interesting, other than the ultimate max advance and retreat of the glaciers is the never ending shorter cycles of advance and retreat – like pulses. Much like the one we’re in today.

    Back to N. America – Lake Missoula

    But today’s climate change will be the end of us.

  4. That is very informative and entertaining. Australia never quite hooked on to the Asian land masses.

    I shared it on Facebook to try to educate a few people.

  5. I am puzzled about the CO2 temperature nexus. I’ve read elsewhere that there is little correlation between CO2 and temp (ice cores). I recall that some data has the CO2 rising after the temperature rose – i.e. lagging. Any comments?
