6,000 years ago was warmer than the present

Hockey Schtick reports a new paper:
A paper published today in The Holocene finds that the elevation of the treeline in the Rocky Mountains of Wyoming was higher than the present from ~9000 to 6000 years ago, indicating the climate was warmer during that period as compared to present temperatures. The paper adds to thousands of others indicating that the current warming period is not unprecedented nor unusual compared to natural warming in the past.
