Modern Iceland’s climate is colder with more ice than any other time in the last 8000 years except the 1800s

A wealth of new research in glacier and sea ice extent show modern Iceland is 2-4°C colder than all of the last 8000 years except for a slightly colder late 19th century. Even the 1700s were warmer with less ice than today in and around Iceland.
A new study (Geirsdóttir et al., 2020) now affirms peak Holocene warmth at least “?3–4 °C above modern in Iceland†prevailed throughout much of the last 8000 years. Data from tree growth, glacier-induced soil erosion, algae productivity, sea ice biomarker proxies (IP25), and other climate indices affirm these conclusions.
Harning et al., 2020 report an overall 7°C Holocene cooling trend In Iceland’s surrounding sea surface temperatures (SST).
“In terms of foraminifera-reconstructed SST there is an overall trend of cooling throughout the last 8 ka from ~10 °C to ~3 °C.â€
