Glaciers have shrunk to the lowest levels ever recorded and are now melting faster than ever, with catastrophic consequences for all life on the planet.

Earth's glaciers have lost 9 trillion tons of ice since 1961 (the weight of 27 billion 747s).

Receding glaciers - climate breakdown takes its toll.

The pictures from this 2012 article are striking:

Fleeing in panic as glaciers collapse...

The Cryosphere.

5 subsets of Earth's snow & ice:

🔹ice-caps
🔹polar sea-ice
🔹permafrost
🔹mountain glaciers
🔹snow-cover

Greenland & Antarctic ice-caps: rapidly losing mass⚠️

Arctic ice: going fast⚠️

Permafrost: collapsing⚠️

Glaciers & snow-cover: vanishing⚠️

Glaciers gone by the end of the 2020s...?

Glaciers gone by the end of the 2020s?  https://time.com/4369987/this-scary-animation-shows-how-glacier-national-park-is-losing-its-glaciers/ 

Estimates on when the glaciers will disappear completely vary widely, from 2030 to 2080, depending on winter weather.

“These glaciers have been around for 7,000 years. What is important is that it will happen in our lifetime.” https://www.pbs.org/newshour/science/glaciers-will-disappear-mainland-u-s-lifetime-scientists-say 

70% of the glaciers in western Canada are projected to be gone by 2100. The Matanuska Glacier’s ancient ice is already rapidly vanishing. Mount Everest is transforming - thousands of glaciers across the Himalayas are likely to shrink by up to 99% within decades.

Gone within decades:

"We urgently need to see significant cuts in greenhouse gas emissions. This is the only way of avoiding long-lasting and irreversible glacier decline and the related major natural, social, economic and migratory cascading consequences" https://www.sciencedaily.com/releases/2019/04/190430105750.htm 

Existing tropical Andean glaciers in Bolivia, Ecuador, and Peru are retreating at an accelerated rate; and, should this continue, all glaciers below 5,000 meters above sea level will be drastically reduced or lost by 2030 or 2040. https://www.thegef.org/content/adapting-impact-rapid-glacier-retreat-tropical-andes

Water levels in the Ganges and the Indus (two of the region’s most important river basins) could drop significantly by 2050, threatening the livelihoods of millions. https://www.climatechangenews.com/2013/08/12/himalaya-glacial-melt-set-to-peak-by-2070/
