National Geophysical Data Center...entire earth + sea floor 2 minute color relief The place Im refering to.
Huge Pock Marks Where the methane ice releases occured I'll try and find an article that refers to the pock marks on the ocean floor.
here is (my) thoughts on this matter...
at the time before the earth warmed due to the methane release , everywhere that is now above the ocean was covered in ice.
nobody lived there...
thus no cities were there...
it makes sence to me.
look at the reliefs and see the old river beds under what is now the oceans.
Old Rivers they are distinct you can follow the paths of these old rivers.
they run from what is now our shore line to deep in the ocean floor.
warm water would not do this only cold icy water would seek the ocean floor.
pay particular attention to the gulf of mexico it is criss crossed in an amazing pattern.
I believe that the reason for the methane ice release was that the oceans kept getting smaller and there depth became less and less , methane ice cannot survive at a depth less than apx 1500 ft , just a little over 1 lap around a 1/4 mile track...thats not far at all when you think of it.
as the ice built up the oceans receded and the water pressure was reduced.
one release led to another and another.
and the warming began.
think of trying to climb up very steep soaking wet mountains as seen in the imagery while torrents of melting water pushed against you.
most of those who tried to escape were probably washed back down into the oceans and drowned.
it all makes sense to me.
