Canada's north is particularly susceptible to devastating effects of climate change. From a ground stability perspective, climate change will cause permafrost degradation as ground temperatures rise in response to global temperatures. Melting permafrost affects all aspects of life in the north including survive-ability, personal mobility, and movement of resources. Putting aside one's opinion as to the underlying causes of climate change, the need to predict the effects of climate change on permafrost is paramount for the future of Canada's north. In order to predict the future, we must first look to the past. GEO-SLOPE Int. is developing new computational capabilities to use climate data as an input for ground temperature computer simulations. First the capabilities must be benchmarked using site-specific conditions, however, there is a dearth of data in the public record. A newly acquired ground temperature database from Distant Early Warning (DEW) Line and North Warning System (NWS) sites located longitudinally across Canada's arctic is now available. Simulating past ground temperatures will develop new computational capabilities, which will then be used to predict climate change effects on permafrost in Canada's north into the future.

加拿大北部特别容易受到气候变化的破坏性影响。从地面稳定性的角度来看，随着全球气温的升高，气候变化将导致永久冻土退化。永久冻土融化影响着北方生活的方方面面，包括生存能力、个人流动性和资源流动。撇开个人对气候变化潜在原因的看法不谈，预测气候变化对永久冻土的影响对加拿大北部的未来至关重要。为了预测未来，我们必须首先回顾过去。GEO-SLOPE Int。正在开发新的计算能力，利用气候数据作为地面温度计算机模拟的输入。首先，必须使用特定地点的条件对能力进行基准测试，然而，公共记录中缺乏数据。从位于加拿大北极纵向的远程预警（DEW）线和北方预警系统（NWS）站点新获得的地温数据库现在可用。模拟过去的地面温度将开发新的计算能力，然后用于预测气候变化对未来加拿大北部永久冻土的影响。
