Warm temperatures have left Great Lakes almost ice-free

The video discusses the impact of mild winters on the Great Lakes, focusing on the reduction of ice cover and its consequences on the ecosystem. Historical data shows a significant decrease in ice coverage, reaching a historic low of 2.7% in February. This lack of ice affects the warming of water, oxygen levels, and the food chain, leading to potential algae blooms and shoreline erosion. Research by Michigan Tech aims to understand these changes and prepare for future climate impacts. The video concludes with a global perspective on record heat levels.

What is the main concern of scientists regarding the Great Lakes' ice cover?
