Natural Variability Has Concealed Increases in Western US Flood Hazard Since the 1970s

Why the Western Pacific Subtropical High Has Extended Westward since the Late 1970s

The western Pacific subtropical high (WPSH) is closely related to Asian climate. Previous examination of changes in the WPSH found a westward extension since the late 1970s, which has contributed to the interdecadal transition of East Asian climate. The reason for the westward extension is unknown, however. The present study suggests that this significant change of WPSH is partly due to the atm...

Change in European Societies since the 1970s

Has the accuracy of energy demand projections in the OECD countries improved since the 1970s?

Since the 1970s almost all OECD countries have published projections or forecasts of future energy consumption. By now, three decades later, the actual values of energy consumption are available for the same number of countries and thus a considerable amount of empirical data is available concerning formal hypothesis testing, e.g. whether there have been improvements in the forecasting accuracy...

Has climate change driven spatio-temporal changes of cropland in northern China since the 1970s?

Improving the understanding of cropland change and its driving factors is a current focus for policy decision-makers in China. The datasets of cropland and cropland changes from the 1970s to the 2000s were used to explore whether climate change has produced spatiotemporal changes to cropland in northern China since the 1970s. Two representative indicators of heat and water resources, which are ...

Interannual variability in western US precipitation

Low-frequency (interannual or longer period) climatic variability is of interest, because of its significance for the understanding and prediction of protracted climatic anomalies. Since precipitation is one of the key variables driving various hydrologic processes, it is useful to examine precipitation records to better understand long-term climate dynamics. Here, we use the multi-taper method...
