New research from the GEODE Lab shows rising temperatures are causing Earth\u2019s coldest forests to shift northward. Drs.\u00a0Logan Berner<\/strong>\u00a0and\u00a0Scott Goetz<\/strong>\u00a0authored a new article, \u201cSatellite observations document trends consistent with a boreal forest biome shift,\u201d that was recently published in\u00a0Global Change Biology<\/a><\/em>. The study focused on the boreal forest, which is a belt of cold-tolerant conifer trees that stretches nearly 9,000 miles across northern North American and Eurasia. The boreal forest accounts for almost a quarter of the Earth\u2019s forest area and is the mostly rapidly warming forest biome. The researchers looked at several decades of moderate-resolution satellite observations and assessed where and why vegetation became greener and browner during recent decades. \u201cOur study shows climate change is causing boreal trees and shrubs to expand into arctic and alpine tundra, while at the same time causing trees to become more stressed and die along the warm southern margins of the boreal forest,\u201d Berner said. \u201cThese dynamics could lead to a gradual northward shift in the geographic extent of the boreal forest biome.\u201d Such a boreal biome shift could have consequences for wildlife, wildfires, and climate feedbacks related to carbon cycling and surface albedo. This study was part of a larger initiative funded by\u00a0NASA\u2019s Arctic-Boreal Vulnerability Experiment<\/a>\u00a0(ABoVE) that will involve further efforts to understand the extent, nature, cause and consequence of an emerging boreal biome shift. Goetz is the science lead for ABoVE.<\/p>\n\n\n\n
