Increasing temperatures will continue to induce changes in mountain regions throughout the 21st century, with expected negative consequences for mountain cryosphere, biodiversity, ecosystem services and human well-being . Many low-elevation and small glaciers around the world will lose most of their total mass at a 1.5℃ global warming level  . A large majority of endemic mountain species will be at risk of extinction; regions heavily relying on glacier melt and snowmelt for irrigation will face erratic water supply and increased food insecurity, whereas agriculture in some regions might see positive changes. Damages and losses from water-related hazards such as floods and landslides are projected to increase considerably between 1.5℃ and 3ºC GWL.
