Climate change: Arctic ice melt makes permafrost vulnerable
[b]The absence of sea ice in the Arctic is closely connected to the melting of permafrost, according to a new study.[/b]
Permafrost contains massive amounts of carbon which are likely to be released as climate change heats up the world.
When this carbon enters the atmosphere as CO2 and methane gas, it will itself contribute to warming the globe.
But scientists have now found a historical link between sea ice in the Arctic and the presence or absence of permafrost.
They say the expected disappearance of Arctic summer ice will speed up the loss of this permanently frozen ground.
This also posseiblities of easier passage through the arctic as well as allow easier exploration of the artic sea with one less level to go through.
