Is it true that the Earth is losing ice at an alarming rate?
assistant
Yes, it’s true. Scientists have observed a significant decline in the volume of polar ice caps and glaciers over the last few decades. The most recent data shows that sea levels are rising at an increasing rate due to the melting of land-based ice sheets and the thermal expansion of ocean water. This poses a threat to coastal cities around the world and could lead to increased flooding and other impacts.
