Experts warn more India glacier disasters can t be avoided without better monitoring By Arshad R. Zargar Glacier collapse kills dozens in India
New Delhi Nearly four days after the partial collapse of a glacier and the subsequent flash flooding of a valley in northern India, rescue workers were still struggling to reach 34 people believed to be trapped in a tunnel in the state of Uttarakhand on Wednesday. Rescue workers armed with heavy construction equipment, drones and even sniffer dogs were struggling to penetrate the one-and-a-half-mile long tunnel that filled with ice-cold water, mud, rocks and debris when the disaster struck on Sunday.
Sea Levels Are Rising Faster Than Scientistsâ Most Pessimistic Forecasts

Climate change is causing sea levels to rise faster than the worst-case scenario predicted by scientists, a new study has found.
The study found âconsiderably greater sea-level rises could be realisedâ than those predicted by recent assessments made by the United Nationâs Intergovernmental Panel on Climate Change (IPCC).

According to the IPCC, the average global sea levels are unlikely to rise by more than 1.1 metres within this century even with the most intensive greenhouse gas emission scenarios.

Study Shows Sea Level will Rise More and Faster than Previously Believed
Written by AZoCleantechFeb 3 2021
When assessing the rise in sea levels, two major elements should be observed. One element is the loss of ice on land, for example, inland ice sheets and melting mountain glaciers on Antarctica and Greenland, while the other is that the sea will increase in size as it becomes warmer. In other words, the sea level will rise quickly with increasing temperatures.

There are two main elements to observe when assessing sea level rise. One is the loss of the ice on land, e.g., melting mountain glaciers and inland ice sheets on Greenland and Antarctica, and the other is that the sea will expand as it gets warmer. The more its temperature increases, the faster the sea will rise. Researchers at the Niels Bohr Institute, University of Copenhagen have constructed a new method of quantifying just how fast the sea will react to warming. The level of the sea is monitored meticulously, and we can compare the responsiveness in models with historical data. The comparison shows that former predictions of sea level have been too conservative, so the sea will likely rise more and faster than previously believed. The result is now published in the Eu
