If you can predict the path of the jet stream, the upper atmosphere's undulating river of wind, then you can predict weather — not just for a week or two, but for an entire season. A new study moves toward that level of foresight by revealing a physical link between the speed and location of the jet stream and the strength of the polar vortex, a swirl of air that usually hovers over the Arctic.

Stormwater ponds not a major source of greenhouse gas emissions
Stormwater retention ponds, a ubiquitous feature in urban landscapes, are not a significant source of climate-warming nitrous oxide emissions, a new study finds. Nitrous oxide is a potent greenhouse gas that contributes to global warming and destroys stratospheric ozone. Previous studies suggested stormwater ponds might be a problematic source of the gas, since they produce it as a by-product of t
