Minnesota experimental forests show modest temperature increases can have big impact

An example of an unheated forest plot
An example of a heated forest plot that's part of the B4WARMED project near Cloquet, Minn. The plot was an average of 3.4 degrees Celsius warmer than a nearby plot that was not heated. Compared to the unheated plot, which was still lush with color, this plot was devoid of most color and almost all leaves had fallen. B4WARMED stands for Boreal Forest Warming at an Ecotone in Danger. The goal of the study is to determine how Minnesota trees will respond to warmer climates.
