All these words and nothing about what form the mercury has. Is it the sulfide, which is quite resistant to decomposition? Might it be desirable to mine mercury from thawing permafrost? Will permafrost ever thaw at all or will a natural ice age overtake our weak (if any) warming, leaving it frozen?
My question is how much—if any—permafrost has actually melted?
While frozen ground melts every Spring the permafrost, hence its name, never melts.
Can we see the numbers on how much has actually melted, that is, ground or land that was once true, established-as-fact permafrost that is now melted (at least in Summer)?
OR...
Is this just computer-modeled speculation that areas of permafrost WILL melt in the future?
