Inertia or reprise? Reconstructing recent alpine treeline dynamics in relation to climate change.

Alpine treelines (the altitudinal limit of the habitat at which trees are capable of growing) are considered monitors of the effects of climate change on forest growth and dynamics. Treelines are expected to react to current climate warming by showing upslope migrations. However, treeline dynamics are often characterized by lagged responses to rising temperatures, that […]

Evidencia del incremento de las sequías sobre la Península Ibérica

Spatial-temporal analysis of the 1970’s Sahel drought

The drought in the Sahel region during most of the 1970’s is one of the most recent mega-drought episodes. Drought-caused famine killed more than 100,000 people, and left more than 750,000 dependent on international aid. Analyzing past drought episodes may help us better understand the onset and development of droughts, especially if we are able […]
