Fig. 3: Area weighted trend of NDVImax and GPPmax.
From: Decadal trends in global grassland growth peaks and their drivers since the 1980s
a, c Area weighted NDVImax and GPPmax during 1982–2021 and 1998–2009 across different IPCC climate regions, with ranking order of trend over 1998–2009. b, d A quadrant diagram plots the NDVImax and GPPmax trend over different periods, with a circle size indicating the area of the regions. * indicates statistically significant trends (P < 0.05), also including more stringent significance levels (P < 0.01, and P < 0.001). “ns” indicates non-significant trends.
