Aug 23, 2021 · When Greenland was green: rapid global warming 55 million years ago shows us what the future may hold. Published: August 23, 2021 5:05am EDT. Volcanic emissions caused the warmest period in past...
Greenland's climate is a tundra climate (Köppen ET) on and near the coasts and an ice cap climate (Köppen EF) in inland areas. It typically has short, cool summers and long, moderately cold winters.

Widespread thermometer measurements of temperatures only extend back to the mid-1700s. Scientists investigating how temperatures have changed prior to the invention of thermometers need to rely on a variety of climate “proxies”, which are correlated with temperature and can be used to infer, with some uncertainties, how it has changed in the past. ...
A temperature reconstruction using the Greenland Ice Sheet Project 2 (“GISP2”) ice core was first published by Prof Kurt Cuffey and Dr Gary Clow in a 1997 paper published in the Journal of Geophysical Research: Oceans. Prof Richard Alley of Penn State University also used the record in a 2000 paper. Neither of these papers provided a comparison of ...
A more modern Greenland temperature reconstruction, based on six different ice cores, was published by Prof Bo Vinther of the Niels Bohr Instituteat the University of Copenhagen and colleagues in Nature in 2009. Speaking to Carbon Brief, Vinther suggests that this multi-core Holocene reconstruction provides a number of advantages over the old GISP2...
While periods during the early Holocene – 7,000-11,000 years ago – may have been warmer in Greenland than the present day, if the present rate of warming continues, the Earth should pass well beyond any temperatures experienced in Greenland during the Holocene by 2050. To examine how future Greenland warming might compare to what has happened in th...
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 temperatu...
Apr 9, 2024 · The climate of Greenland is Arctic, modified only by the slight influence of the Gulf Stream in the southwest. Rapid weather changes, from sunshine to impenetrable blizzards, are common and result from the eastward progression of low-pressure air masses over a permanent layer of cold air above the island’s icy interior.
