Rising Antarctic Earth to Influence Future Sea Levels - Miragenews  (Aug 6) |
|
Aug 6 · The rising earth beneath the Antarctic Ice Sheet will likely become a major factor in future sea level rise, a new study suggests. Despite feeling like a stationary mass, most solid ground is undergoing a process of deformation, sinking and rising in response to many environmental factors. In Antarctica, melting glacial ice means less weight on the bedrock below, allowing it to rise. How the rising earth interacts with the overlying ice sheet to affect sea level rise is not well-studied, said Terry Wilson, co-author of the study and a senior research scientist at the Byrd Polar and Climate Research Center at The Ohio State University. In the new study, Wilson's ... Read more ... |

Turning carbon dioxide into valuable products - Miragenews  (Sep 07, 2022) |
|
Sep 07, 2022 · Carbon dioxide (CO2) is a major contributor to climate change and a significant product of many human activities, notably industrial manufacturing. A major goal in the energy field has been to chemically convert emitted CO2 into valuable chemicals or fuels. But while CO2 is available in abundance, it has not yet been widely used to generate value-added products. Why not? The reason is that CO2 molecules are highly stable and therefore not prone to being chemically converted to a different form. Researchers have sought materials and device designs that could help spur that conversion, but nothing has worked well enough to yield an efficient, cost-effective system. Two ... Read more ... |
