Nanomaterials describe, in principle, materials of which a single unit is sized (in at least one dimension) between 1 to 1000 nanometres (10−9 meter) but usually is 1 to 100 nm (the usual definition of nanoscale).
Climate change impacts, such as rising temperatures, prolonged droughts and extreme precipitation, are expected to affect many areas, including mountain regions. A large consortium worked to develop advanced models to quantify and predict the impact of climate change primarily on surface water.
