This chapter outlines evidence of direct and indirect changes in the ecology of Arctic Alaska caused by changes in the climate, and predicts ecological changes that could occur by the year 2100. It looks into the alterations that have been carried out and that will happen to air temperatures, precipitation, water balance, river discharge, and arctic sea ice in Northern Alaska. It describes the possible physical responses to climate changes in active-layer thickness, possible warming of the permafrost, and the increased formation of thermokarst. It highlights the increased possibility of wildfire during periods of low rainfall, and the changes in microbial processes due to warming. It also looks at various ecological consequences such as accelerating global warming due to the permafrost thawing which may release greenhouse gases to the atmosphere.

Keywords:   Arctic Alaska, air temperature, precipitation, water balance, river discharge, thermokarst, permafrost thaw, greenhouse gases, global warming
