Alaska Shatters Heat Records with Sweltering Day

ANCHORAGE, AK – The Last Frontier experienced an unprecedented thermal surge as temperatures soared, marking the hottest day ever recorded in Alaska. On July 4, 2019, the mercury hit a staggering 90 degrees Fahrenheit (32 degrees Celsius) in Anchorage, the state’s largest city, shattering the previous high of 85 degrees set in 1969.

Uncharted Territory for Alaskan Climate

The record-breaking temperature was part of a prolonged heatwave that gripped much of Southcentral Alaska, prompting concerns about wildfire risks and melting glaciers. Climate scientists point to this extreme event as a clear indicator of the shifting weather patterns associated with global warming. The anomalous heat has had significant impacts on local ecosystems, wildlife, and the daily lives of Alaskans.

Response to the Heatwave

Local authorities issued health warnings and opened cooling centers to help residents cope with the heat. The unusual weather also affected the state’s infrastructure, with reports of buckling roads and train track expansions. Alaskans, more accustomed to dealing with subzero temperatures, found themselves seeking relief in swimming holes and air-conditioned spaces.

Heatwave: A prolonged period of excessively hot weather, which may be accompanied by high humidity.
Global Warming: The long-term rise in the average temperature of the Earth’s climate system, largely due to human activities such as burning fossil fuels.
Mercury: A common term used to refer to the temperature, as mercury is the liquid used in traditional thermometers to measure heat.
