Ulmus rubra (Grey Elm, Red Elm, Slippery Elm, Soft Elm) | North These potential scenarios demonstrate how climate outcomes can vary depending on human decisions and emissions through this century. 2010. Studies that thoroughly document the seasonal progression of acclimation and provide graphical representations of the timing of actual or potential injury from low-temperature events at all three stages in the annual cycle include those by McNamara et al.
