That's according to a recent study that found social factors -- such as low population density, high housing vacancy, disability and race -- can have a stronger influence than median household income on whether a community's municipal water supply is more likely to have health-based water-quality violations.

The study is the first to quantify the national disparity of disadvantaged communities living in levee-protected areas, which puts people at increased risk of flooding and other issues.

The study authors highlight that neighborhoods with predominantly Black, Hispanic and Latinx residents would benefit the most -- potentially reducing disproportionate pollution and health burdens in historically marginalized areas.

Using satellite data, researchers have shown that the relationship between water droplets in clouds and aerosol concentration is more non-linear than previously thought. Specifically, in heavily polluted regions, the additional warming of the Earth resulting from better air quality could occur much later than originally believed -- perhaps as much as 20 or 30 years later than expected.

This is among the first studies to report biomarker metal levels among marijuana users and most likely the largest study to date, that links self-reported marijuana use to internal measures of metal exposure, rather than just looking at metal levels in the cannabis plant. The results are important because marijuana is the third most used drug in the world.

Over 60 million carbon credits came from projects that barely reduced deforestation, if at all. Of a potential 89 million credits from these offset schemes, only 5.4 million (6%) were linked to additional carbon reductions through preserved forest.

Human activity in hotspots of global trade, such as maritime ports, is linked to an increased likelihood of non-native tree species invasions. However, a high diversity of native tree species can help to curb the intensity of such invasions.

The surrounding habitat, not temperature, is the important driver of methane emissions. The findings could improve methane estimates and models of climate change, and point to land-management changes and restoration opportunities that can reduce the amount of methane escaping into the atmosphere.

To accomplish this goal, large cuts in emissions are necessary, especially in high-emission sectors like the building industry. Researchers use a computational model to analyze several scenarios of future building energy use in the US. They find that by tackling emissions on multiple fronts and placing focus on 'demand-side measures' that affect how power is drawn from the grid, such as technologies like electric heat pumps and smart thermostats, the US can achieve its climate goals, decrease building emissions by 91% from their 2005 peak, and save over $100 billion each year on energy costs.
