Final answer:
The sea ice extent in the Arctic is at a minimum in September due to the melting during the summer season.
Step-by-step explanation:
In the Arctic, the annual cycle of sea ice follows a predictable pattern. As temperatures rise during the summer months, the ice melts and reaches its minimum extent around September. This period marks the end of the melting season when the ice cover shrinks to its smallest size before temperatures drop again in the approaching winter. Various factors, such as increased sunlight and warmer temperatures, contribute to this seasonal melting. The Arctic's minimum ice extent is a crucial indicator of climate change, as it has been decreasing over the years due to global warming, impacting not only the environment but also ecosystems and wildlife dependent on sea ice for survival. Monitoring this minimum extent helps scientists understand the rapid changes occurring in the Arctic and their implications for the planet's climate system.
The minimum sea ice extent in the Arctic typically occurs in September.
