A century of temperature variability in Lake Superior

  title={A century of temperature variability in Lake Superior},
  author={Jay A. Austin and Steve Colman},
A 100-yr-long time series of water temperature measured just downstream of Lake Superior is used to produce proxy time series of open-lake temperature. This analysis suggests that open-water Lake Superior summer temperatures have increased by roughly 3.5uC over the last century, most of that warming occurring in the last three decades. Correspondingly, the length of the positively stratified season has increased from 145 d to 170 d. The observed amount of warming is greater than the observed… CONTINUE READING
