News Release 10-Nov-2021
Peer-Reviewed Publication
University of Arizona
A University of Arizona-led effort to reconstruct Earth's climate since the last ice age, about 24,000 years ago, highlights the main drivers of climate change and how far out of bounds human activity has pushed the climate system.
The study, published this week in Nature, had three main findings:
It verified that the main drivers of climate change since the last ice age are rising greenhouse gas concentrations and the retreat of the ice sheets.
It suggests a general warming trend over the last 10,000 years, settling a decade-long debate about whether this period trended warmer or cooler in the paleoclimatology community.
The magnitude and rate warming over the last 150 years far surpasses the magnitude and rate of changes over the last 24,000 years.
