Mapping pollution estimates at street level to reveal safer roads

source: GeoHealth The United Nations has identified improving walkability and cycling in cities as a key goal in efforts to reduce reliance on cars that emit greenhouse gases and promote routine exercise for public health. However, increased walking and cycling can have health risks of their own. Time spent outdoors, in addition to other factors, …

Let It Snow, Inside for Science: A CSU scientist studies snow processes in a unique lab

In Colorado headwaters, snowpack is king. Colorado State University snow hydrologist Stephen Fasnacht recently traveled to one of the world’s most advanced snow laboratories to study this important resource and how snow affects water management and climate prediction. To allocate water wisely, water managers need to know how much is available, but estimates based on …

The Mauna Loa eruption in Hawaii is a gift to science

The world’s largest volcano has erupted for the first time since 1984. It has raised Mauna Loa in Hawaii, a giant hill that looks so much like Mars that researchers have already simulated Mars there. Authorities say the volcanic eruption does not threaten any local communities; No evacuation orders were issued. For scientists, it’s an …

Earth is “unequivocally” in the midst of a climate emergency

More than 14,000 scientists from 158 countries signed the original report. 16 of the planet’s 35 vital indicators that researchers use to measure climate change are at all-time highs. Biomarkers on Earth have deteriorated to such an extent that “humankind is unequivocally facing a climate emergency,” according to a study recently published by a global …
