How the micrometeorology of alpine forests affects snowmelt

A field study in the Swiss Alps showed considerable spatial and temporal variability in forest air and surface temperatures, with implications for snowmelt models.Warming temperatures in spring herald the melting of snow in mountains and higher-latitude regions. Predicting the timing and speed of snowmelt is important for local communities as they prepare for knock-on effects …

Unlocking the secrets of the Sahara

A peat bog in Romania provides a new insight into our knowledge of when the Sahara began to transform from grassland into the desert we know today, and the impact this had on dust deposition within Eastern Europe. Using carbon dating and chemical analysis, researchers from Northumbria University, Newcastle have shown that significant changes in …
