They might seem like unlikely allies, but ranchers and prairie conservationists have a future working together.

More accurate maps of bed topography reveal physical processes controlling retreat.

More than a decade after beekeepers first raised the alarm about a dangerously low global bee population, much progress has been made in understanding the mystery of colony collapse.

The impacts of global warming are felt especially in mountainous regions, where the rise in temperatures is above average, affecting both glacierized landscapes and water resources. The repercussions of these changes are manifold and varied, from retreating glaciers to an increase in the frequency and intensity of snow avalanches. A team of researchers from the University of Geneva (UNIGE), Switzerland, has employed dendrochronology– the reconstruction of past disasters as recorded in growth series of trees– to disentangle the role of global warming in the triggering avalanches. The results of this study are published in the Proceedings of the National Academic of Science – PNAS.

The new Arctic Now product developed by the Finnish Meteorological Institute shows with one picture the extent of the area in the Northern Hemisphere currently covered by ice and snow.
