As climate warming stokes longer fire seasons and more severe fires in the North American boreal forest, being able to calculate how much carbon each fire burns grows more urgent. New research led by Northern Arizona University and published this week in Nature Climate Change suggests that how much carbon burns depends… Read more

NAU global change ecologist leads NASA satellite study of rapid greening across Arctic tundra
As Arctic summers warm, Earth’s northern landscapes are changing. Using satellite images to track global tundra ecosystems over decades, a team of researchers finds the region has become greener as warmer air and soil temperatures lead to increased plant growth.
“The Arctic tundra is one of the coldest biomes on Earth, and it’s also one of the most rapidly warming,” said Logan Berner, assistant research professor with Northern Arizona… Read more
NAU researchers urge tropical forest protection
NAU scientists contribute to critical new global study showing ‘best of the last’ tropical forests urgently need protection to mitigate climate change, safeguard human well-being
The world’s ‘best of the last’ tropical forests are at significant risk of being lost, according to a paper released today in Nature Ecology and Evolution. Of these pristine forests that provide key services—including carbon storage, prevention of disease transmission and water provision—only a mere 6.5 percent… Read more
Forests can be risky climate investments to offset greenhouse gas emissions, say NAU scientists
Given the tremendous ability of forests to absorb carbon dioxide from the atmosphere, some governments are counting on planted forests as offsets for greenhouse gas emissions—a sort of climate investment. As with any investment, however, it’s important to understand the risks. If a forest goes bust—through severe droughts or wildfires, researchers say—much of that stored carbon could go up in smoke.

Larger, more frequent fires in the boreal forest threaten previously protected carbon stores, NAU-led research team reports in Nature
Pools of old carbon in the soil of boreal forests historically safe from combustion are being released by more frequent and larger wildfires, a team led by researchers at Northern Arizona University announced in Nature this week. As the climate of these forests in the Northwest Territories of Canada becomes warmer and drier and prone to more frequent… Read more
