It’s Official: Greenland Has Not Warmed Since 2001: The Recent Sharp Warming Lasted From 1981-2000

Since 2001, the temperature trends across Greenland have stopped rising

4 Conclusions

Our updated analysis of Greenland coastal and inland weather station records shows strong and significant warming since 1991 in all seasons (~1.7°C in summer and ~4.4°C in winter), where the summer warming compares well between coastal and inland (Swiss Camp, Summit) sites; however, trend analysis for 2001–2019 highlights compensating short?term warming and cooling before and after 2012 that gives no significant net temperature change at most stations. However, flatter or slightly declining temperature trends for some sites since around 2010 are generally insignificant and well within the scope of natural variability. Summer 2019 saw near?record warmth and melt but was not quite as warm as summer 2012 over most of Greenland except at Summit and in the north; however, summer 2019 had a record number of blocked days over Greenland, and was notable for its peak warmth and melt (31 July) occurring relatively late in the melt season, which also coincided with the date of peak blocking.
