🧊Have You Ever Seen a Glacier in Person?
A glacier can look permanent—quiet, enormous, almost too old to change. But it’s changing faster than many of us realize.Since 1975, glaciers worldwide have lost more than 9 trillion tonnes of ice. In 2025 alone, another 408 billion tonnes disappeared—enough to fill five Olympic-sized swimming pools every second for an entire year.Researchers modelled more than 200,000 glaciers and found that with 1.5°C of warming, more than half could disappear by 2100. At 2.7°C, only around one-fifth may remain. Every fraction of a degree can affect how much ice survives. Between 1990 and 2020, glaciers across the Hindu Kush–Himalayan region lost about 12% of their area and 9% of their ice reserves.And the risks don’t end when the ice disappears. Rapid melting can destabilize mountain slopes and increase the risk of floods, avalanches, and landslides. Shrinking glaciers can also reduce dry-season river flows, while rising sea levels threaten coastal communities. The recent glacier and rock collapse near the Nepal–China border showed how quickly changes in the mountains can affect communities downstream. Across the United States, longer heat waves, heavier downpours, flash floods, and dangerous wildfire conditions are also becoming more familiar.This is one reason cleaner energy matters. Saving energy at home, choosing efficient appliances, and using solar panels where practical can all help reduce our dependence on fossil fuels. As home solar becomes more accessible, more households can generate electricity with fewer emissions. No single household can protect a glacier on its own. But millions of individual choices, supported by cleaner technology and stronger policies, can help slow the warming that puts them at risk.Have you ever seen a glacier or permanent snowfield in person? What natural place do you hope will still look the same 50 years from now?And if you use solar energy, what convinced you to make the switch? 🌍Sources: WGMS, WMO, ICIMOD, ETH Zurich, NOAA, and U.S. EPA
