New measure of tropical forest vulnerability to help avoid ‘tipping point’

(Cell Press) Humid tropical forests, vital in global efforts to limit rising temperatures, are under threat as a result of changes in land use and climate. Now, researchers reporting in the journal One Earth on July 23 have developed a new way to keep tabs on the vulnerability of these forests on a global scale …

New tests can detect tiny but toxic particles of coal ash in soil

(Duke University) Duke University scientists have developed tests sensitive enough to detect and measure microscopic particles of coal ash in soil, even at concentrations so low and sizes so small that other tests would likely miss them. The four new tests complement tests previously developed at Duke to detect coal ash contamination in water and …

California’s carbon mitigation efforts may be thwarted by climate change itself

(University of California – Irvine) To meet an ambitious goal of carbon neutrality by 2045, California’s policymakers are relying in part on forests and shrublands to remove CO2 from the atmosphere, but researchers at the University of California, Irvine warn that future climate change may limit the ecosystem’s ability to perform this service. ​(University of …
