Among the listed modern technologies, microscopes to study things too small to be seen with the human eye would be the least helpful to humans as we deal with natural hazards like hurricanes.
While microscopes are invaluable for many scientific fields, including biology and materials science, they do not provide direct assistance in understanding or managing large-scale natural phenomena such as hurricanes. In contrast, satellites, communication technologies, and computers used for predictive modeling are all critical for monitoring, forecasting, and responding to hurricanes and other natural disasters.
