“If the world can preserve the temperature rise to under 1.5 levels Celsius, within the HKH area, it will translate to not less than an increase of 1.eight levels, and in some locations, above 2.2 levels. Himalayan areas are additionally the least monitored area and this occasion really reveals how weak we may very well be.
