Children living in urban areas with high levels of air pollution, noise and traffic may be at higher risk of childhood obesity, according to a study by the Barcelona Institute for Global Health (ISGlobal)—a centre supported by the ”la Caixa” Foundation—and the University Institute for Primary Care Research Jordi Gol (IDIAP Jordi Gol). The study was funded by the La Marató de TV3 Foundation.

Snowmelt – the surface runoff from melting snow – is an essential water resource for communities and ecosystems. But extreme snow melt, which occurs when snow melts too rapidly over a short amount of time, can be destructive and deadly, causing floods, landslides and dam failures.

To better understand the processes that drive such rapid melting, researchers set out to map extreme snowmelt events over the last 30 years. Their findings are published in a new paper in the Bulletin of the American Meteorological Society.

"When we talk about snowmelt, people want to know the basic numbers, just like the weather, but no one has ever provided anything like that before. It's like if nobody told you the maximum and minimum temperature or record temperature in your city," said study co-author Xubin Zeng, director of the UArizona Climate Dynamics and Hydrometeorology Center and a professor of atmospheric sciences. "We are the first to create a map that characterizes snowmelt across the U.S. Now, people can talk about the record snowmelt events over each small area of 2.5 miles by 2.5 miles."

The transportation sector is the largest contributor to greenhouse gas emissions in the United States, and a lot of attention has been devoted to electric passenger vehicles and their potential to help reduce those emissions.

Rather than waiting for certainty in sea-level rise projections, policymakers can plan now for future coastal flooding by addressing existing inequities among the most vulnerable communities in flood zones, according to Stanford research.

Plant material that lies to rot in soil isn’t just valuable as compost.
