Predicting the weather a few days in advance is a complex undertaking. But what about the weather 3 to 4 weeks from now? Producing that kind of forecast is a daunting challenge  — but is crucial for a slew of communities. These future forecasts, called sub-seasonal predictions, can help energy companies determine how much power to produce to meet demands for upcoming months; they assist water resource managers controlling reservoir levels ahead of upcoming water use; they even help farmers understand which crops to plant in the face of potential dry weather.

Chemical products like household cleaners, pesticides, paints and perfumes that contain compounds refined from petroleum now rival motor vehicle emissions as the top source of urban air pollution, according to a surprising NOAA-led study.

Tropical trees in the Amazon Rainforest may be more drought resistant than previously thought, according to a new study by researchers at the University of California, Riverside.

New CU Boulder-led research has established a causal link between climate warming and the localized extinction of a common Rocky Mountain flowering plant, a result that could serve as a herald of future population declines. 

Humans and fruit flies may have not shared a common ancestor for hundreds of millions of years, but the neurons that govern our circadian clocks are strikingly similar.

Thanks to lucky snapshots taken by an amateur astronomer in Argentina, scientists have obtained their first view of the initial burst of light from the explosion of a massive star.

The ocean around the Galápagos Islands has been warming since the 1970s, according to a new analysis of the natural temperature archives stored in coral reefs.

A hybrid population of mountain pine beetles is set to do further damage to one of Canada’s most iconic regions.

The debate is over. Dietary protein supplements significantly improve muscle strength and size when taken by healthy adults who lift weights, a determination reached by McMaster scientists who analyzed dozens of research studies.

The reality of climate change poses a significant threat to global biodiversity. As temperatures rise, the survival of individual species will ultimately depend on their ability to adapt to changes in habitat and their interactions with other species.
