A speleothem has revealed rapid periods of warming across the interior of the continent during the last glacial period, corresponding to similar events recorded in Greenland ice.
When predicting a tree’s annual growth, consider the whole weather system and not just the sum of its parts.
By making clear-cut forests patchier, moose create a reflective surface that bounces back sunlight and keeps temperatures down.
Enhanced tree growth could significantly offset carbon emissions, but some researchers say it’s not enough to compete with forest disturbances.
The differences between future and present subseasonal predictability in the Northern Hemisphere provided by the tropics are evaluated using neural networks.
When glaciers melt, the land below deforms. Sea level data show that widely used models oversimplify the process.
Stratospheric fluorine species have accumulated faster in the Northern Hemisphere over the past two decades reflecting interhemispheric differences in the Brewer-Dobson transport circulation.
The two hemispheres feature the same planetary albedo despite a larger land fraction in the north, because storms over the southern ocean are cloudier than their northern counterparts.
The seasonal amplitude of atmospheric CO2 is increasing, partly due to boreal forest responses to warming. Photosynthesis and expansion of boreal forests are shown here to be temperature-limited.
