Human-Induced Climate Change Directly Linked to Flood Risk in Glacial Lakes
Written by AZoCleantechFeb 5 2021
The warming of Earth has caused glaciers to retreat, leading to changes in mountain water systems across the globe.

Researchers from the University of Oxford and the University of Washington (UW) have, for the first time, directly linked human-induced climate change to the threat of flooding from a glacial lake one of the worst flood risks in the whole world.
This image of Saturn s icy, geologically active moon Enceladus was acquired by NASA s Cassini spacecraft during its October 2015 flyby. Enceladus hides a global ocean of liquid salty water beneath its crust and might also have hydrothermal vents not unlike the hydrothermal vents that dot the ocean floor here on Earth.

New research led by the American Museum of Natural History and funded by NASA identifies a process that might have been key in producing the first organic molecules on Earth about 4 billion years ago, before the origin of life. The process, which is similar to what might have occurred in some ancient underwater hydrothermal vents, may also have relevance to the search for life elsewhere in the universe. Details of the study are published this week in the journal
Scientists Ask: Can Nanotech And Microbes Partner To Destroy PFAS?

Researchers will use analytical and computational techniques to understand, in detail, how PFAS degrade at each step of the proposed treatment process
Imagine this: In a wastewater treatment plant, engineered molecular-scale scissors chop up PFAS, toxic compounds that are so tough to break down that they’re called “forever chemicals.” Then, microbes digest the molecular scraps, clearing them from the water.
In a new project, researchers from the University at Buffalo and University of Pittsburgh are teaming up to design the approaches and tools that would make such a system possible. The group will seek to develop advanced catalytic carbon-metal nanomaterials that react with and snip PFAS (per- and polyfluoroalkyl substances), and to identify and isolate bacteria capable of consuming

A new analysis of a horse previously believed to be from the Ice Age shows that the animal actually died just a few hundred years ago and was raised, ridden and cared for by Native peoples. The study sheds light on the early relationships between horses and their guardians in the Americas.
The findings, published today in the journal
American Antiquity, are the latest in the saga of the Lehi horse.

As the planet warms, glaciers are retreating and causing changes in the world s mountain water systems. For the first time, scientists at the University of Oxford and the University of Washington have directly linked human-induced climate change to the risk of flooding from a glacial lake known as one of the world s greatest flood risks.
The study examined the case of Lake Palcacocha in the Peruvian Andes, which could cause flooding with devastating consequences for 120,000 residents in the city of Huaraz. The paper, published Feb. 4 in
