Two new studies suggest that recent estimates of global ice melt are conservative. In other words, ice is melting much more rapidly than experts thought. As a result, sea levels are rising faster as well.
The first study combines various observations from satellites, on-the-ground measurements, and model-based estimates to create a clearer picture of the state of Earth’s ice between 1994 and 2017. Essentially, it captures a global tally of change in ice mass over that time period. The resulting measurements of ice loss and sea level rise fall in the upper range of scenarios forecast by the Intergovernmental Panel on Climate Change (IPCC), a body within the United Nations meant to provide objective science related to climate change. The IPCC’s scenarios were laid out in their 2019 special report on oceans and the cryosphere, itself a recent overview of assessment work.

The Data Is Clear: Himalayan Glaciers Are in Distress 12/02/2021

Glacial calving high up in the Himalayas caused a flash flood in the Indian state of Uttarakhand that killed dozens and washed away new dams and bridges. Calving – the breaking away of large chucks of ice from a glacier – is not typical in winter, so but it is likely that global warming has played a role in the disaster. As
The New York Times reports, glaciers in the region are shrinking fast, elevating the risk of floods and landslides. The Indian government ignored warnings about the region’s environmental instability when it went ahead with the now destroyed hydroelectric developments.

A deadly flood in northern India, sparked by a cratering glacier, was not an isolated incident but the result of a rapidly warming planet, say experts. They warn the disaster, which has left over 140 feared dead, is a precursor of what is to come unless drastic measures are taken to slow climate change.
The flood this week in the Himalayan state of Uttarakhand was caused by a glacier breaking away and falling into the valley, sending a surge of water downstream that engulfed villages and workers at a hydroelectric plant.
