Changes in rainfall seasonality in the tropics

Climate change has altered not only the overall magnitude of rainfall but also its seasonal distribution and interannual variability worldwide. Such changes in the rainfall regimes will be most keenly felt in arid and semiarid regions, where water availability and timing are key factors controlling biogeochemical cycles5, primary productivity, and the phenology of growth and reproduction, while also regulating agricultural production.

Everest snowline melting, glaciers shrinking, new study reveals

Rise in temperatures and a fall in the amount of precipitation in the Mount Everest region has led to a majority of mountain glaciers shrinking by 30 percent along with an upward movement of snowli

Dependence of hydropower energy generation on forests in the Amazon Basin at local and regional scales

Tropical rainforest regions have large hydropower generation potential that figures prominently in many nations’ energy growth strategies. Feasibility studies of hydropower plants typically ignore the effect of future deforestation or assume that deforestation will have a positive effect on river discharge and energy generation resulting from declines in evapotranspiration (ET) associated with forest conversion. Forest loss can also reduce river discharge, however, by inhibiting rainfall.
