Beef farming that keeps cattle on lifelong grass diets may have higher carbon footprint

Beef farming that keeps cattle on lifelong grass diets may have higher carbon footprint

Beef operations that keep cattle on lifelong grass-based diets may have an overall higher carbon footprint than those that switch cattle to grain-based diets partway through their lives. Daniel Blaustein-Rejto of the Breakthrough Institute, USA, and colleagues present these findings in the open-access journal PLOS ONE on December 13. Cattle on lifelong grass diets are … Read more

Pacific Northwest snowpack endangered by increasing spring heatwaves

Pacific Northwest snowpack endangered by increasing spring heatwaves

Even in the precipitation-heavy Pacific Northwest, more frequent heatwaves are threatening a key source of water supply. A Washington State University study that intended to look at snow melting under a single, extreme event, the 2021 “heat dome,” instead revealed an alarming, longer-term rising trend of successive heatwaves melting snowpack earlier in the year. The … Read more

How forests smell — a risk for the climate?

How forests smell — a risk for the climate?

Leipzig. Plants emit odours for a variety of reasons, such as to communicate with each other, to deter herbivores or to respond to changing environmental conditions. An interdisciplinary team of researchers from Leipzig University, the Leibniz Institute for Tropospheric Research (TROPOS) and the German Centre for Integrative Biodiversity Research (iDiv) carried out a study to … Read more

The solar forest | ScienceDaily

A verdant forest is one of the most iconic symbols of the power of nature, from the abundance of plant and animal life that shelters among its thick vegetation to the positive impact it has on Earth’s climate, thanks in part to photosynthesis, which removes carbon dioxide from the air, thereby mitigating the effects of … Read more

Aquatic insects in restored streams need more rocks to lay their eggs

Aquatic insects in restored streams need more rocks to lay their eggs

Likening it to providing more runways at busy airports, researchers at North Carolina State University found in a new study that adding protruding rocks to restored streams can help attract female aquatic insects that lay their eggs on the rock bottoms or sides. More eggs that hatch into larval insects is great news for stream … Read more

National policy aimed at reducing U.S. greenhouse gases also would improve water quality

National policy aimed at reducing U.S. greenhouse gases also would improve water quality

A climate policy that raises the price of carbon-intensive products across the entire U.S. economy would yield a side benefit of reducing nitrate groundwater contamination throughout the Mississippi River Basin. The Gulf of Mexico, an important U.S. fishery, also would see modest benefits from the nitrate reductions. These were among the conclusions of a recent … Read more
