    “…The microscopic mechanism of RS-OPC suggested that the active SiO(2) in the RS can react with Ca(OH)(2) to produce C-S-H but can only utilize small quantities of Ca(OH)(2), confirming the low volcanic ash activity of RS. RS was responsible for dilution and filling. …”

    “…SIMPLE SUMMARY: Epidemiological observations indicate that the incidence of thyroid cancer is increased in volcanic areas. Indeed, in the volcanic area of Sicily, where residents are biocontaminated by volcano-originated, low-level, multi-elemental metal pollution, the thyroid cancer incidence is double that in non-volcanic areas. …”

    “…During the pre-industrial period (AD 1000–1800) variability in the sub-polar North Atlantic leads changes in Northern Hemisphere surface air temperatures at multi-decadal timescales, indicating that North Atlantic Ocean dynamics played an active role in modulating the response of the atmosphere to solar and volcanic forcing.…”

    “…The most widely known solar geoengineering proposal is stratospheric aerosol injection (SAI), which has impacts analogous to those from volcanic eruptions. Observations following major volcanic eruptions indicate that aerosol enhancements confined to a single hemisphere effectively modulate North Atlantic tropical cyclone (TC) activity in the following years. …”
