To slide or not to slide: the evolution of topography and sediment dynamics in landslide prone regions by Benjamin Campforts, Institut of Arctic and Alpine Research, University of Colorado, Boulder   From an engineering perspective, we often think of landslides as a natural hazard that predominantly occurs in steep terrain.

Tropical river deltas are hotspots of humanactivity, but their vulnerability to flood risks is increasing due to sea levelrise and worldwide conversion of mangroves, acting as natural buffers againstmarine flooding, into human land use. Moreover, extreme sea levels notablydriven by climatic fluctuations such as the El Niño-Southern Oscillation, areprojected to intensify with global warming.

Tree-ring widths represent the most commonly used proxy to reconstruct the climate of the last millennium at high resolution, thanks to their large-scale availability. The approach often relies on a relationship between tree-ring width series and climate estimated on the basis of a linear regression. The underlying linearity and stationarity assumptions may be inadequate.
