Reaction of continental mountain climates to the postulated “global warming”: evidence from Alaska and the Yukon Territory

Examination of the climatic data for Alaska and the Yukon Territory fails to show the warming trend predicted by CO2 climate-change models. Instead, there is a large area affected by a sudden 2 °C rise in temperature between 1975 and 1980, while the core of the continental mountain change appears to be buffered from the warming seen in data from the marginal mountain slopes and the adjacent lowlands. This appears to be due to a combination of steam fog, cold air drainage, and air mass inversions in closed mountain basins. The implications for permafrost distribution and engineering construction are briefly discussed.
