permafrost

She urged anyone with doubts to go to Alaska , where the permafrost is dying , or to California 's Sierra Mountains , where snow is melting earlier in the spring , creating havoc for water supplies .

她敦促持怀疑态度的人前往阿拉斯加，那里的永冻土层将要消失，或者前往加利福尼亚州的塞拉山脉，那里的冰雪在早春时节便已融化，严重破坏了水供给。

It might be possible for similar organisms to survive for billions of years below the permafrost layer on Mars , where water is liquid , radiation supplies energy , and carbon dioxide provides carbon .

类似的生物体有可能在火星的永冻土层下面生活了上亿年，那里的水是液态的，放射提供能量，二氧化物提供碳的来源。
