Climate change is having significant impacts on mountain ecosystems. Average temperatures in mountains worldwide have risen 0.54 degrees Fahrenheit per decade, leading to melting glaciers and changes in river flows. This disrupts plants and wildlife and increases risks of floods and rockslides. As glaciers continue to melt with rising CO2 and greenhouse gas levels, snow accumulation zones will shrink and new lakes will form, altering water availability for agriculture and hydropower. Premature snowmelt in Rocky Mountain National Park has already caused water supply difficulties for species that rely on snowmelt, threatening to disrupt the park's ecosystem.
