The paper goes on to argue that the PDSI, which has been relied upon for drought characterization since the 1960s, is too simple a measure and may (the authors» word) have led to overestimation of global drought trends in previous climate - change assessments — including the IPCC's previous (2007) assessment, which found that «More intense and longer droughts have been observed over wider areas since the 1970s, particularly in the tropics and subtropics.»

It is also that capitalogenic global warming (CGW) has done fundamental and irreversible damage to agricultural productivity — primarily through more pervasive and crippling global droughts, along with help from the development of herbicide - resistant and CGW - friendly «super weeds» and antibiotic - resistant livestock diseases — so that a return to cheap food, a requirement for a re-expansion of cheap labor, may be impossible.
