permafrost

"These permafrost deposits are now melting and releasing their methane," said Maslin.

“这些永久冻中的沉积物始融化，并释放出甲烷，”麦斯林说。

Thermokarst failures occur when permafrost—a layer of frozen soil in Earth's polar regions—thaws and becomes unstable, possibly releasing greenhouse gases into the atmosphere.

随着永久冻带消溶和分崩离析，热喀斯特现象大量出现，埋藏于地下的（甲烷等）温室气体可能散发到大气中。

As the industry puts more and more focus on developing and utilizing oil and gas resources in the paramos and permafrost zone, pipeline construction in the areas will be definitely accelerated.
