New ecological studies being published lately all point to the same basic conclusion: the stress of climate change is killing the world's forests.
One study, released by a team at the University of Colorado Boulder, reveals that mid-elevation forests (those at altitudes roughly between 2,000 to 2,500 metres) represent an ecological "tipping point" between the more moisture-dependent forests at lower elevations and the more sunlight and temperature-dependent forests at higher elevations.

Mid-elevation forests depend the most on the annual snow-pack that accumulates at those altitudes, and are therefore the most vulnerable to climate change. Researchers used satellite measurements of 'forest greenness' and measurements of snow depth from ground-based instruments. They found that as global temperatures rise, there is a reduction in the depth of the snow-pack, and this leaves theseRead More »from Stress of climate change killing forests, new studies show
