Don should have a look at Siberia where rising temperatures have caused rising mounds of earth to explode due to methane and CO2 being released from unstable perma frost. The same is apparently happening with melting ice releasing the same gases. I understand the same is happening in Alaska and Northern Canada. Too much of this stuff releasing could lead to a runaway greenhouse condition.Firstly to address your wail from a couple of posts up. Warragamba might be spilling now, but Thomson hasn't filled or spilled since 1996. You obviously think that Warragamba is Australia's only dam. Keepit, in the God-forsaken drylands of northern NSW and only a few hours drive from flood stricken Moree is only 60% full.https://indifferencegivesyouafright.wordpress.com/2012/08/06/tim-flannery-did-not-say-australias-dams-would-never-fill-again/I knew that denial was going to come up - read the interview for yourself (I linked purposely so you can make up your own mind) and decide what he was saying. I think it was purposely alarmist - and he tried to walk it back later on when there were heavy rains in 2010 and other subsequent years.
He's said other things: Other climate change super-stars have made some pretty bold predictions that haven't come through either - Al Gore said the Arctic would be free of summer ice on German TV once and then retracted the prediction when it didn't come through.
There were really hugely expensive mistakes made because of that advice, not the least of which is the VIC desal plant at Wonthaggi, clearly a really expensive Bracks decision that will be a millstone around VIC water users for a few more decades to come.
Your Gore reference has been debunked so many times, yet you still cum in your pants over it. in his speech, Gore referenced someone else who made that claim, yet you continually try to pin it on him directly (for newbies here, I have previously challenged don_dunstan for a link to prove his position and all he could come up with is "It's on youtube somewhere, look it up yourself" or similar).
Fun fact: Wonthaggi desal plant prevented Melbourne from suffering through water restrictions last summer.
Lightening could also ignite the methane gas and exacerbate the problem.
Don reminds me of King Canute trying to hold back the ocean, even when the water covers his head.
The changes I referred to above are not BS but actually happening.
