I read the whole thread on my phone, very slowly, during work yesterday. Today, i post a reply, very slowly, during work
This is an awesome first
thread Doug, i just hope it spawns the discussion it deserves. This thread threw a lot of light bulbs on in my head, about ice and sea levels. Go
google 'applet sea level rise' or something like that. There's a link to this awesome app that you can adjust sea level with, unfortunately it's
based solely on existing plates, but i'm sure its good enough. I did some noob research and here's some interesting things; it would take over 5,000
metres of water to cover the earth, including mountains. 500 metres would cover half the land area. If all the ice, everywhere on earth, was to melt
it would only account for about 70 metres of sea level rise. On the other hand, during the wisconsinan glaciation (the last ice-age) which lasted from
110,000 - 10,000 years ago, sea levels were a lot lower. Maximum ice extent occured at 21,000 years ago, sea level was 140 metres lower than today.
10,000y ago, 40m lower. 8,000y ago, 20m lower. 6,000y sea level basically jumps and levels out to todays norm. Doug, you should have a gander at
australia say 8,000 years ago, it hit me how much it looks like antarctica and how easy it looks to get there by boat.
I'm no expert on anything. You didnt mention much about australia, but i remember reading about a some mix-up in the old world about australia and
antarctica. Could it be possible that for his new map he used an old source that was australia and he mistook it for an updated map of antarctica..
Eish, i wish i was on my home pc... I dont have much confidence in my last statement, but i'll put it out there regardless. I'm sure i'll learn
Ps. I'll try come back later and put some links in here for backup. Sweet. Thanks again for one exceedingly well forged thread. Peace
