05: Present Weather and Climate: Evolving Conditions

Present Weather and Climate: Evolving Conditions reveals the variability and trends of the region’s climate using data from weather instruments and paleoclimate records (such as tree rings), comparing the climate of the last 100 years with that of the last 1,000 years, and linking patterns of past climatic conditions to the variability of river flows in the region’s major water basins.
