The blue line shows estimates of Arctic temperatures over the past 2,000 years based on proxy records from lake sediments, ice cores and tree rings. A 2,000-year climate simulation with the National Center for Atmospheric Research's climate system model showed a similar temperature decrease. The red line shows Arctic temperatures based on actual observations, beginning in 1865.
