The upcoming century could see trees in the continental US producing spring leaves an average of 17 days earlier than in the past century, according to a new study by Princeton University researchers. The good news: These changes could lead to changes in the composition of northeastern forests and give a boost to their ability to take up carbon dioxide.  Trees play an important role in taking up carbon dioxide from the atmosphere, so researchers wanted to evaluate predictions of spring budburst — when deciduous trees push out new growth after months of winter dormancy — from models that predict how carbon emissions will impact global temperatures. read more
