Time to Adapt to a Warming World, But Where’s the Science?
-
With dangerous global warming seemingly inevitable, users of climate information—
from water utilities to international aid workers—are turning to climate scientists for
guidance. But usable knowledge is in short supply

Timing of climate variability and grassland productivity
-
Future climates are forecast to include greater precipitation variability and more frequent heat waves, but the degree to which the timing of climate variability impacts ecosystems is uncertain. In a temperate, humid grassland, we examined the seasonal impacts of climate variability on 27 y of grass productivity. Drought and high- intensity precipitation reduced grass productivity only during a 110-d period, whereas high temperatures reduced productivity only during 25 d in July. The effects of drought and heat waves declined over the season and had no detectable impact on grass productivity in August. If these patterns are general across ecosystems, predictions of ecosystem response to climate change will have to account not only for the magnitude of climate variability but also for its timing.

TN Wild Side - Brook Trout Restoration
-
The Southern Appalachian Brook Trout is small... so small in fact that a trophy fish is only nine inches long. This beautiful fish, vibrant with shimmery, bright colors is considered a prize catch, largely because the brook trout is a rare and elusive resident of Tennessee waters. It's the only trout native to our state and the Tennessee Wildlife Resources Agency and others are trying to make sure it doesn't disappear. Wild Side Guide Alan Griggs takes us to the Cherokee National Forest near Tellico Plains, where some young brook trout are returning home after nearly being wiped out in their mountain habitat.
