What is said about the safety of ice in extreme conditions?

The assertion that no ice is completely safe emphasizes the inherent risks associated with ice, particularly in extreme conditions. Ice can vary significantly in strength and stability based on several factors, such as temperature fluctuations, the presence of water currents, or recent weather changes, which can create weak spots. Even ice that appears thick can be compromised by these variables, making it potentially dangerous for activities like walking or driving on it. This reminder reinforces the importance of exercising caution and not assuming that ice is safe simply because it is cold or frozen, as conditions can change rapidly and unpredictably.
