Permafrost zonation and climate change in the northern hemisphere : Results from transient general circulation models

Anisimov and Nelson compare contemporary permafrost distribution in the northern hemisphere, calculated using the "frost-index" approach, with a recent map based on empirical data. Results generally suggest a more restricted poleward retreat of the permafrost zones than those derived from...

Description
Summary:Anisimov and Nelson compare contemporary permafrost distribution in the northern hemisphere, calculated using the "frost-index" approach, with a recent map based on empirical data. Results generally suggest a more restricted poleward retreat of the permafrost zones than those derived from 2 times CO2 models.
