NASA Examines Peru's Deadly Rainfall
March 24, 2017 03:09 PM - NASA / Goddard Space Flight Center

The Global Precipitation Measurement mission or GPM constellation of satellites provide data on precipitation rates and totals. Recently the GPM core observatory measured the heavy rainfall that caused extensive flooding and loss of life in Peru.

Extreme flooding and frequent landslides that occurred in March have forced many from their homes. An El Niño-like condition with warm ocean waters developed near Peru's coast. This extremely warm water off Peru's western coast has been blamed for promoting the development of these storms. Equatorial sea surface temperatures (SSTs) are about average elsewhere in the central and east central Pacific.

Rice U. refines filters for greener natural gas
March 23, 2017 03:37 PM - Mike Williams via Rice University

Natural gas producers want to draw all the methane they can from a well while sequestering as much carbon dioxide as possible, and could use filters that optimize either carbon capture or methane flow. No single filter will do both, but thanks to Rice University scientists, they now know how to fine-tune sorbents for their needs.

Subtle adjustments in the manufacture of a polymer-based carbon sorbent make it the best-known material either for capturing the greenhouse gas or balancing carbon capture with methane selectivity, according to Rice chemist Andrew Barron.

Measuring the 'true social cost' of carbon dioxide emissions

University of Oxford

The US National Academies of Sciences, Engineering, and Medicine has proposed a new framework for US agencies to use to estimate the 'social cost of carbon dioxide' emissions. Myles Allen, Professor of Geosystem Science at the Environmental Change Institute, helped compile the report which will strengthen the scientific basis and provide greater transparency for US climate policy.
