Climate Change In Alaska
Climate change, in Alaska as elsewhere, is a contentious subject. We state up front that the ASCC and the Alaska State Climatologist take no formal stance on the subject of global climate warming.
We do believe that the available evidence suggests Alaska's climate is indeed changing. This is not a surprising or controversial conclusion — climate is constantly in a state of flux that involves many spatial and time scales. The role of the ASCC is to provide timely information on current and past climate records. This data may then used by ourselves and others to draw conclusions regarding climate change —and potential consequences — for Alaska.
GLOBAL WARMING vs. CLIMATE CHANGE
The purpose of this page is to present thoughtful, well-reasoned, and scientifically-based material, which probably spans the whole spectrum of the subject area.
Misconceptions and unfounded assertions abound in this subject area, so fraught with emotional and political overtones. It is important to recognize that there is a difference between the study of climatology and climate change, though certainly the former informs the latter. Alaska climatology in its myriad forms is what the ASCC is all about.
There is also a big difference between "global warming" and "climate change" on whatever scale it takes place. Certainly, warming is one major factor in climate change. However, worries about global warming are overshadowed by the regional effects of climate change. Issues such as temporal and spatial changes in precipitation, relative timing of freeze-up and break-up, cloudiness, seasonal sea-ice concentration and storminess all have a much greater impact on Alaskans' lives than a few degrees of warming per century. It seems reasonable to concentrate on these local and regional factors in the discussion of climate change as it is experienced in Alaska. In the following section we provide links to a few of the myriad sources that consider these phenomena. Collecting and linking to these sources is an ongoing task and we welcome suggestions for additions on this list. We acknowledge that this is far from an exhaustive list on the subject.
Our listing DOES NOT in any way suggest an endorsement of these sites' content or conclusions other than the fact that we deem them based more on fact than on political persuasion or specific ideology.
