A heatwave is defined as prolonged periods of excessive heat and are categorized as a specific type of extreme temperature event. These events are not a new phenomenon, though they have become increasingly regular since 1950.
This year, the National Weather Service issued heat advisories for the State of Alaska for the first time ever. With temperatures expected to reach 89 degrees Fahrenheit, local communities were urged to take extra precautions.
Climate Scientist Brian Brettschneider explains that while high heat is not necessarily new to Alaska, they are not prepared for such events, and it has major impacts on their comfort and health. Since Alaska is built primarily to withstand freezing temperatures, most Alaskans begin to suffer heat-related health problems at a 70 degree Fahrenheit threshold.
Arctic amplification is a very real phenomenon that is causing significant ice melting, which in turn allows for more heat to get trapped in the atmosphere. Indigenous Alaskans have been demanding that their voices are heard in climate conversations for years.
