Last ice age's massive iceberg discharges had no impact on Greenland.

Heinrich Events, massive iceberg discharges during the last ice age, had no impact on nearby Greenland, according to a new study from Oregon State University researchers. Instead, these events caused rapid warming in Antarctica, at the other end of the globe. The finding challenges the current understanding of global climate dynamics during these massive events and raises new questions for researchers. The ultimate goal is to better understand how the climate system is connected and how the components all interact.
