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]:

ocean circulation disrupted

(eg.) Atlantic meridional ocean circulation

wave El-Niño/[illegible]

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.
