Thriving Arctic Bottom Dwellers Could Get Strangled by Warming
-
Many biologists hypothesize that climate change could hurt the Arctic benthos and the large creatures that live off it by wiping out ice (and hence ice algae), lengthening growing seasons for zooplankton, and giving warm- water species a foothold. “The way the system works now is very much in favor of the benthos,” says UAF polar ecologist Rolf Gradinger. “If the sys- tem changes, things could go downhill fast.”

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.
