<human>:  How has climate change affected glaciers?
<bot>: Climate change has had a profound effect on glaciers around the world. Rising global temperatures are causing glaciers to melt at an accelerated rate, leading to a decrease in their overall size. This has caused decreased water availability in some regions, which can have a detrimental impact on local ecosystems and communities who depend on glacial meltwater for their survival. Additionally, the increased melting of glaciers can lead to more extreme weather patterns and increased flooding in certain areas.
