Future research recognizing and documenting complex patterns

There has been a rapid accrual of evidence of changes in physical and nonhuman biological systems, in association with regional warming trends. Taken together, these indicate a signal that global climate change is now beginning to change the conditions of the biophysical environment around us (Root et al., 2003). This raises an obvious question. Is similar evidence emerging of changes in occurrence of infectious diseases that are plausibly due to recent or ongoing regional changes in climate? That is, can we develop formal methods of "pattern recognition"? Particular attention has recently been paid to reports of changes in malaria in eastern and southern Africa, tick-borne encephalitis in Sweden, and the temporal correlation of cholera outbreaks in Bangladesh with recently-intensifying El NiƱo events.
