Main Body
[IPCC AR 6] Specific report was released in 2021, which projected increase in floods, landslides, etc. are due to glacier melting.
more recently, (in 2023), (IPCC report) was released - Upsub-day dyed into effect of melting glaciers on Himalaya.
Effects of melting glaciers on environment:
1. (Irreversible ice sheet) [illegible] Inevitable State of decline.
If it melts completely -> 5-6m of ice level rise.
coastal areas permanently destroyed
2. Irreversibly threatened to potential to raise sea level by 70m.
3. Melting of [Himalayan glaciers]:
(eg.) Atlantic meridional ocean circulation
4. Marine ecosystem Impacted
Marine food chain disrupted
Marine biodiversity
5. Natural disasters:
glacial lake outburst floods (GLOF)
GLOF (eg) Uttarkashi May
6. Biodiversity vulnerability to heat (cold waves)
7. Human factors:
( → ) [human-made global warming]
[ → anthropogenic global warming]
["deforestation" leading to uneven distribution]
Hence, it is important to properly understand impact of all these factors, to build capacity against climate change.
