Arctic Sea Ice Extent Data, 1901-2015 — arcticseaice • stevedata

This data set from Connelly et al. (2017) measures the Arctic sea ice extent in 10^6 square kilometers. It includes lower bounds and upper bounds on annual averages.

Usage

arcticseaice

Format

A data frame with 115 observations on the following 4 variables.

year: the year
value: the annual Arctic sea ice extent (in 10^6 sq km)
ub: The upper bound of the value, provided by Connelly et al.
lb: The lower bound of the value, provided by Connelly et al.

Details

This is for illustration of climate change for my intro students. Connelly et al. (2017) are in part a methodological paper. The data I present here are from the "rescaled (unadjusted T)" data in the second sheet from their replication files.
