Researchers have found a connection between seismic slip and nonvolcanic tremor in the Cascadia subduction zone, potentially increasing stress on the megathrust fault. The findings suggest that slow slip events may lead to increased risk of megathrust earthquakes.
Researchers suggest using 30% of global crop residues to sequester 600 megatons of carbon in the deep ocean, reducing atmospheric CO2 by up to 15%. The process would be 92% efficient and minimize environmental damage if done correctly.
In the Pacific Northwest, tree mortality rates have doubled in 17 years, with older forests experiencing a faster rate of decline than younger forests. This increase is attributed to warming temperatures, which reduce snowpack, prolong droughts, and enable insects and diseases to flourish.
Researchers found that 10-month-old infants can use prior information to understand novel actions, but not when performed in a different location. The study suggests that providing advance information about a person's goals helps infants learn from another person's actions.
