A group of researchers, including ATMO‘s Rob Wood, have published a comprehensive paper on marine cloud brightening, to shed light on what we do and don’t know about this geoengineering possibility. They argue that we can, and should, gather more information about marine cloud brightening as a way to slow global warming, including performing small-scale experiments.

This week a team of marine researchers have published an index to assesses overall ocean vitality. The index, described this week in Nature, comprises ten separate measures that are aggregated into a single score of how well the seas are doing. The ten measures — which assess features such as food provision, carbon storage, tourism value and biodiversity — were chosen to reflect both the needs of humans and ecosystem sustainability. 

Salmon-habitat watersheds need a good mix of steep, cold-running streams and slower, meandering streams of warmer water to keep options open for salmon adapted to reproduce better in one setting than the other, new research shows. Preserving such a varied landscape doesn’t just serve salmon, it also ensures an all-summer buffet that brown bears, gulls and other animals need to sustain themselves the rest of the year. 

A new study by CoEnv scientists evaluates the heat stress variables that may lead to a drop in milk production for cows across the country. This work will be featured in the International Conference on Climate Change: Impacts and Responses, which will be held on campus this Thursday and Friday. Yoram Bauman, affiliate professor at Program on the Environment, and Guillaume Mauger and Eric Salathe’ of Climate Impacts Group, are co-authors, with Tamilee Nennich of Purdue University.
