"We can study the meteorological cycle on another planetary body involving a different molecule (methane)," said Emily Schaller, of the University of Arizona's Lunar and planetary Laboratory.

“我们可以在另一个涉及不同分子(甲烷)的行星上研究大气循环，”埃米丽·夏特说，她是亚利桑那大学卫星和行星研究室的研究员。

They fear the warming caused by increased methane emissions will itselfrelease yet more methane and lock the region into a destructive cycle thatforces temperatures to rise faster than predicted.

他们担心甲烷排放量的增加引起的气候变暖将导致更多的甲烷释放，把该地区锁定成破坏性循环，迫使温度上升速度比预期更快。

Now it aims to speed up the methane production cycle from years to a matter of days at the same time as cutting the need for more land to bury garbage.

现在他们的目标是加快甲烷产品的生产周期，从几年变成几天，同时减少对掩埋更多垃圾的土地需求。

Moreover, although controversial, life-cycle analysis indicates that fugitive methane emissions make shale gas obtained by hydraulic fracturing as carbon-intensive as coal.

But lakes of methane, and an earth-like weather cycle of evaporation, condensation and precipitation, are still possible.
