Systems and methods for collecting and processing permafrost gases and for cooling permafrost are disclosed herein. A method for processing gas in a permafrost region includes obtaining a gas from a sacrificial area of a thawing permafrost region, dissociating the gas in a non-combustive chemical process, and circulating a constituent of the gas through a savable area of the thawing permafrost region to cool the savable area. This process can be used to cool selected areas of permafrost and/or create clean-burning fuels and/or other products from permafrost gases.
