Analysis suggests attitudes, not income, drive energy savings at home

Some people flip off the lights the moment they leave a room, while others rarely think twice about saving energy. According to the most comprehensive analysis of people's sentiments toward household energy savings to date, published in the journal Cell Reports Sustainability, people's attitudes and moral sentiments about their energy usage—rather than income or knowledge of how to conserve power—determine whether they take action at home.

Properly managed urban rainwater could also be used for cleaning or irrigation purposes

EHU researchers have explored how a sustainable urban drainage system built in Legazpi has affected various rainwater parameters, and have concluded that a permeable pavement has improved the quality of runoff water and has reduced turbidity, suspended solids and the amount of certain metals.

Destined to melt: Study warns glaciers' ability to cool surrounding air faces imminent decline

Glaciers are fighting back against climate change by cooling the air that touches their surfaces. But for how long? The Pellicciotti group at the Institute of Science and Technology Austria (ISTA) has compiled and re-analyzed an unprecedented dataset of on-glacier observations worldwide. Their findings, published today in Nature Climate Change, demonstrate that glaciers will likely reach the peak of their self-cooling power by the next decade before their near-surface temperatures spike up and melting accelerates.

To prevent rapid sea-level rise, study urges reducing emissions now

The timing of emissions reductions, even more so than the rate of reduction, will be key to avoiding catastrophic thresholds for ice-melt and sea-level rise, according to a new Cornell University study.

Toxic pollution builds up in snake scales: What we learned from black mambas

Black mambas (Dendroaspis polylepis) are Africa's longest, most famous venomous snakes. Despite their fearsome reputation, these misunderstood snakes are vital players in their ecosystems. They keep rodent populations in check and, in turn, help to protect crops and limit disease spread. The species ranges widely across sub-Saharan Africa, from Senegal to Somalia and south into South Africa. They can adapt to many environments.

Sustainable practices could cut food-related emissions in half

Food systems make up roughly 30% of total greenhouse gas emissions globally. But transforming them could cut these emissions by more than half, according to a report released Oct. 3 from a commission of global experts from more than 35 countries across six continents.
