CLIMATE - Spring may come earlier to North American forests, increasing uptake of carbon dioxide

Trees in the con­ti­nen­tal US could send out new leaves in the spring up to 17 days ear­lier in the com­ing cen­tury than they did before global tem­per­a­tures started ris­ing, accord­ing to a new study. . These climate-driven changes could lead to changes in the com­po­si­tion of north­east­ern forests and give a boost to their abil­ity to take up car­bon dioxide.
