Melting Himalayas
The glaciers covering the Himalayas are melting much faster than anywhere else on Earth. If the current trend continues, they will lose 80% of their mass in the next 25 years.
The rapid pace of the melt is homemade: the smog of wood fires and exhaust fumes. This 'brown cloud' warms the high mountains at a far stronger pace than the earth does. "In the past a thick blanket of snow covered these mountains." The major Himalayan countries have good prospects in the fight against this threat if they agree quickly on a common strategy. "When the glaciers are gone, there will be no water here."
