    The arctic cold outbreak of January 2019 will go down as the coldest in parts of the upper Midwest since the 1990s, shattering numerous daily records and even topping a few all-time cold records, while creating wind chills as cold as the 60s below zero.

    (NEWS: Impacts From the Cold Outbreak)


    Mount Carroll, Illinois, may have set a new all-time record low for the state of Illinois Thursday morning, Jan. 31, with a temperature of minus 38 degrees

    1. January 30, 2019: Record-breaking cold swooped down from Canada, affecting the entire Midwest. Per the Des Moines Register, the capital city hit -20 degrees with wind chills near -40, making it the coldest Jan. 30 in the history of Des Moines. The all-time coldest day was Jan. 5, 1884, when they hit -30. Sadly, this cold weather did take at least 11 lives, one of which was a University of Iowa student.

    The arctic ocean's ice puts a cap on evaporation
    lose that cap and the evaporate can fall as snow on the land surrounding the arctic ocean
    the snow may accumulate faster than it can melt
    the accumulation may build glaciers

    This mechanism was proposed by Ewing and Donn 1956 theory of the causes of Ice Ages

    and then
    Maureen Raymo et.al. found that sea level rose rapidly at end eemian---just before the recent period of glaciation started

    these 2 bits seem connected, but I have found no study combining the 2
