American Association for the Advancement of Science (AAAS) How temperate and boreal trees' leaves respond to climate change remains uncertain. Now, a new study of northern forests reports that while early-season climate warming – that occurring before the summer solstice – tends to be associated with earlier autumn leaf senescence, late-season warming (after the summer solstice) has the opposite impact, delaying onset of leaf senescence in fall. "Improved models of plant development and growth under climate change will need to incorporate the reversal of warming effects after the summer solstice," write Constantin Zohner and colleagues, authors of the study.
