In chihlinwei/SCC85: Seafloor Climate Change Projections from CIMP5

#' Model-average Earliest Time of Emergence based on variability
#'
#' Earliest time of emergence was estimated as the first year when climate change variability exceeds
#' historical climate variability.
#'
#' @details
#' Earliest time of emergence was calculated as the first year when the yearly cumulative future standard deviation
#' exceed the historical yearly standard deviation \code{\link{cimp5_1951_2000_sd}}.
