Time series of the spatially-averaged annual mean of frequency (a), participating days (b), maximum duration (c), mean duration (d), maximum intensity (e), and mean intensity (f) of winter warm spells over global land areas from 1979 to 2023. The straight line indicates the linear trend, and the shading indicates the corresponding 90% confidence interval. Slope and p-value estimates for the trend per decade are given in parentheses.
