8 Climate crisis weakened glacier that caused devastating Nepal-Tibet floods killing over 1,000¶

A glacier collapse on Langtang Lirung in Nepal on August 26 killed over 1,300 people across Nepal and Tibet. Researchers at Imperial College London confirmed that global heating created unusually warm conditions that destabilized the glacier, making climate change a contributing factor to the disaster.

Glacier collapse released 110 million cubic meters of snow and ice
Floods traveled at speeds exceeding 110 mph
Over 1,300 killed; more than 5,000 missing
Global heating destabilized glacier before collapse
Study published September 16–17, 2026

7 Nepal-Tibet glacier collapse linked to fossil fuel pollution, climate action needed¶

A glacier on the Nepal-Tibet border collapsed killing at least 1,300 people with over 5,000 missing, causing devastating floods that damaged 13 hydropower plants. Research by Imperial College London links fossil fuel pollution to destabilizing conditions that contributed to the collapse, and Nepal is seeking $20 million from the UN's loss and damage fund toward rebuilding costs of approximately $5 billion.

At least 1,300 confirmed dead; over 5,000 missing, some trapped in hydropower tunnels
Glacier collapse occurred three weeks before September 17, 2026
Fossil fuel pollution linked to environmental destabilization contributing to collapse
Nepal requesting $20 million from UN loss and damage fund
Total rebuilding cost estimated at approximately $5 billion including up to 20,000 homes

8 Global Rivers Hit Near 35-Year Low Water Levels in 2025¶

Global rivers experienced one of their driest years in over three decades in 2025, according to the World Meteorological Organisation. Global freshwater reserves fell to 42% below normal levels, with only one-third of rivers flowing normally and the last seven years showing the fewest normal-flow rivers since 1991.

Global freshwater reserves depleted to 42% below normal
Only one-third of rivers flowing at normal levels
36% of global river basin area experienced below-normal flows
Last seven years (2019–2025) had fewest normal-flow rivers since 1991
Climate impacts driving erratic water cycle with swings between excessive water and severe droughts

7.5 New road project threatens Amazon ecosystem fate¶

Brazil is paving the BR-319, a 540-mile highway through untouched Amazon rainforest connecting Amazonas state to the rest of Brazil. While locals support the project for economic development, scientists warn it will open previously inaccessible regions to deforestation, threatening 150–200 billion tons of stored carbon and global climate.

BR-319 is 540 miles of dirt highway through Amazon being paved
Road connects Amazonas state (4.2 million people) to rest of Brazil
Currently impassable during rains; historically took truck drivers up to 22 days to traverse
Amazon stores estimated 150–200 billion tons of carbon in plants and soils
Scientists warn paving will enable deforestation of previously inaccessible regions

7.5 Forest protection more cost-effective than restoration for biodiversity and climate¶

Economic analysis shows protecting existing tropical forests is more cost-effective for biodiversity and climate outcomes than restoring degraded lands.

7 Ethiopia's Green Legacy Initiative plants 50 billion trees across the country¶

Ethiopia's Green Legacy Initiative is planting 50 billion trees to restore forests lost to agricultural expansion, logging, and charcoal use over the past 25 years. Ordinary citizens, including grassroots leaders like Halima Kedir, are driving the reforestation effort despite initial community skepticism.

Target: 50 billion trees across Ethiopia
From 2000 to 2025, Ethiopia lost 560,000 hectares (2,160 square miles) of tree cover
Loss caused by agricultural expansion, commercial logging, charcoal fuel use
Citizen-led efforts; example: Halima Kedir planted thousands of trees in Berbere district, Oromia region
Framed as solution to climate change and food insecurity
