evidence: Factcheck: What Greenland ice cores say about past and present climate change [...] Greenland ice cores provide a high-quality high-resolution estimate of past changes in temperatures, allowing more precise comparisons with observed temperature records than most other climate proxies. While current temperatures are likely still below the highs in the early Holocene around 7,000 years ago, they are clearly higher than any temperatures experienced in Greenland over the past 2,000 years. Greenland is just one location and temperature variations seen in ice core records may not be characteristic of global temperatures. However, global proxy reconstructions have tended to show similar patterns, with current temperatures lower than the early Holocene maximum.
