| Livestock antibiotics and rising temperatures disrupt soil microbial communities Posted: 08 Nov 2021 01:14 PM PST Community ecologists investigated the interactive effects of rising temperatures and a common livestock antibiotic on soil microbes. The research team found that heat and antibiotics disrupt soil microbial communities -- degrading soil microbe efficiency, resilience to future stress, and ability to trap carbon. |
| Scientists issue new climate adaptation 'scorecard' Posted: 08 Nov 2021 01:14 PM PST A new study offers a 'scorecard' for climate adaptation projects -- a set of 16 criteria that can be used to evaluate climate adaptation projects and inform their design. |
| Why did glacial cycles intensify a million years ago? Posted: 08 Nov 2021 01:14 PM PST A study says the Mid-Pleistocene Transition may have been linked to previous erosion of continental soils that subsequently allowed glaciers to stick to the underlying hard bedrock more efficiently. |
| Why nitrous oxide emissions should factor into climate change mitigation Posted: 08 Nov 2021 01:14 PM PST A newly published study found that a range of agricultural soils produce nitrous oxide emissions in sufficient quantities to contribute to climate change. The researchers compared soils with various moisture content and found agricultural soils are capable of high nitrous oxide emissions across a wide range of environmental conditions. |
| New study pinpoints likely path of COVID-related plastic waste in the ocean Posted: 08 Nov 2021 01:14 PM PST Researchers use a new model to project where the surge of mismanaged medical waste will end up—including beaches, seabeds, and the Arctic Ocean. |
| Warming temperatures increasingly alter structure of atmosphere Posted: 08 Nov 2021 10:09 AM PST Climate change is having an increasing impact on the structure of Earth's atmosphere, a new international study shows. The research draws on decades of observations to quantify that warming temperatures are playing a greater role in pushing up the top of the lowest level of the atmosphere by about 50-60 meters per decade. |
| Air pollution disproportionally affects people of color, lower-income residents in DC Posted: 08 Nov 2021 10:02 AM PST The rates of death and health burdens associated with air pollution are borne unequally and inequitably by people of color and those with lower household income and educational attainment in Washington, D.C., according to a new study. The study found that while deaths and health burdens associated with PM2.5 halved between 2000 and 2018 in the D.C. area, disparities and geographical segregations in health effects persist. |
| Helping smooth New Zealand sea lions’ road home Posted: 08 Nov 2021 05:16 AM PST A team creates a new way of redefining New Zealand sea lions' habitat. The work will help take the surprise out of coming across sea lions on a forest hike. |
| Black carbon aerosols heating Arctic: Large contribution from mid-latitude biomass burning Posted: 04 Nov 2021 11:01 AM PDT Researchers have revealed that the year-to-year spring variation in Arctic black carbon aerosol abundance is strongly correlated with biomass burning in the mid-latitudes. Moreover, current models underestimate the contribution of BC from biomass burning by a factor of three. |
