A word prompt for Flashback Friday

Cold, wet and exhausted she struggled to keep her webbed feet on the ice. She slid around, without a firm footing on anything. Only months before the lake was bristling with fish.
They had flown south for the winter. The autumn colours bitter sweet. Beautiful, but the change of seasons were imminent. When we flew back the ice still covered the lake.
We were all in shock, but an idea slowly formed. A few days flight to the east, and I was sure the weather would be warmer. We were tired, that was true, but we couldn’t stay here.
Global warming they said it was, but I couldn’t see how my world was getting colder. If this got any worse I didn’t know what would happen to my family. They were about to fly the nest, have their own families.
I was worried, scared for their future, but for now we fly again.
Nice take on both prompts. Global warming affects all living creatures, not just humans.
