What is the number of glaciers the Swiss alp s have lost since 1850?

Since 1850, the Swiss Alps have lost approximately 1,200 glaciers, significantly reducing their total number from around 3,000 to about 1,800. This dramatic retreat is largely attributed to climate change and rising temperatures, which have accelerated glacial melting. The loss of these glaciers has profound implications for the region's ecosystems, water supply, and tourism.
