Drier summers and a decline in average snowpack over the past 40 years have severely hampered the establishment of two foundational tree species in subalpine regions of Colorado’s Front Range, suggesting that climate warming is already taking a toll on forest health in some areas of the southern Rocky Mountains.

Carbon monoxide can improve the effectiveness of antibiotics, making bacteria more sensitive to antibiotic medication, according to a study led by Georgia State University.

Environmental scientists at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory have led an international collaboration to improve satellite observations of tropical forests.

The Silk Road pattern in meteorology, is a wave-like teleconnection pattern in summer propagating eastward under the wave-guidance of the upper-tropospheric Asian westerly jet stream. It shows up as alternate southerly and northerly anomalies (or cyclonic and anticyclonic circulation anomalies) along the jet, and is the leading mode of the interannual variability of upper-tropospheric meridional winds. It is interesting that this meteorological teleconnection pattern covers most domains along the ancient Silk Road, and exerts significant influences on climatic anomalies over a broad area of the Eurasian continent.

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.
