Synchronous crop failures and climate-forced production variability

Crop production in a northern climate

Potential monitoring of crop production using a satellite-based Climate-Variability Impact Index

The capabilities of the MODerate resolution Imaging Spectroradiometer (MODIS) present some exciting possibilities for improved and timely monitoring of crop production. A quantitative index is introduced in this paper to study the relationship between remotely sensed leaf area index (LAI) and crop production. The Climate-Variability Impact Index (CVII), defined as the monthly contribution to an...

Separating Internal Variability from the Externally Forced Climate Response

Separating low-frequency internal variability of the climate system from the forced signal is essential to better understand anthropogenic climate change as well as internal climate variability. Here both synthetic time series and the historical simulations from phase 5 of CMIP (CMIP5) are used to examine several methods of performing this separation. Linear detrending, as is commonly used in s...

Separating forced from chaotic climate variability over the past millennium

Reconstructions of past climate show notable temperature variability over the past millennium, with relatively warm conditions during the Medieval Climate Anomaly (MCA) and a relatively cold Little Ice Age (LIA). Multimodel simulations of the past millennium are used together with a wide range of reconstructions of Northern Hemispheric mean annual temperature to separate climate variability fro...

Impact of Climate Variability on Cool Weather Crop Yield in Ethiopia

The research examined effect of climate variability on yield of the two dominant cool weather cereals (wheat and barley) in central highland and Arssi grain plough farming systems of Ethiopia using eight round unbalanced panel data (1994-2014). The stochastic frontier model result revealed that production inputs for producing wheat and barley in the two farming system had significant effect. Cr...
