    Abstract

    As the Arctic warms, vegetation is responding, and satellite measures indicate widespread greening at high latitudes. This ‘greening of the Arctic’ is among the world’s most important large-scale ecological responses to global climate change. However, a consensus is emerging that the underlying causes and future dynamics of so-called Arctic greening and browning trends are more complex, variable and inherently scale-dependent than previously thought. Here we summarize the complexities of observing and interpreting high-latitude greening to identify priorities for future research. Incorporating satellite and proximal remote sensing with in-situ data, while accounting for uncertainties and scale issues, will advance the study of past, present and future Arctic vegetation change.

    Funding

    We thank the Inuvialuit and Greenlandic People for the opportunity to conduct field research on their land. Data collection on Qikiqtaruk–Herschel Island was funded by the UK Natural Environment Research Council (NERC) NE/M016323/1 (to I.H.M.-S.) and a National Geographic Society grant CP-061R-17 and a Parrot Climate Innovation Grant (to J.T.K.). Data collection at Kangerlussuaq, Greenland was supported by the US National Science Foundation (NSF) grants 0724711, 0713994, 0732168, 0902125, 1107381, 1525636, 1748052 and the National Geographic Society (to E.P.), as well as an Arctic Institute of North America Grant-in-Aid (to C.J.). The sTundra working group was supported by sDiv, the Synthesis Centre of the German Centre for Integrative Biodiversity Research (iDiv) Halle-Jena-Leipzig (DFG FZT 118). The Event Drivers of Arctic Browning workshop was funded by P3-Plant Production and Protection (http://p3.sheffield.ac.uk/). Several members of the team are supported by the NASA ABoVE program (https://above.nasa.gov/). Additional funding was provided by the Research Council of Norway grant 287402 (to J.W.B. and H.T.) and 294948 (to F.S., J.W.B., A.B., H.T. and F.-J.W.P.), the NERC doctoral training partnership grant NE/L002558/1 (to J.J.A. and H.J.D.T.), the US NSF grants OPP-15-04134, AGS-15-02150 and OPP-16-03473 (to L.A.-H.), the Natural Sciences and Engineering Research Council of Canada and the Canadian Centennial Scholarship Fund (to S.A.-B.), the Academy of Finland decision 256991 and JPI Climate 291581 (to B.C.F.), the NASA ABoVE grants NNX17AE44G and NNX17AE13G (to S.J.G. and L.T.B.), NSF grants PLR-0632263, PLR-0856516, PLR-1432277, PLR-1504224, PLR-1836839 (to R.D.H.), the US NSF grant PLR-1417745 (to M.M.L.), an NERC IRF NE/L011859/1 (to M.M.-F.), Independent Research Fund Denmark 7027-00133B and Villum Fonden VKR023456 (to S.N.), the Norwegian Research Council grants 230970 and 274711 and the Swedish Research Council registration 2017-05268 (to F.-J.W.P.), University of Zurich Research Priority Program on Global Change and Biodiversity (to G.S.-S.) and the US NSF grants OPP-1108425 and PLR-1108425 (to P.F.S.).
