The Impact of Global Warming on Viral Diseases
Zell, R., Krumbholz, A. and Wutzler, P. 2008. Impact of global warming on viral diseases: what is the evidence? Current Opinion in Biotechnology 19: 652-660.
Based on their review, the three German researchers report that "only very few examples point toward global warming as a cause of excess viral activity." Instead, they determined that "coupled ocean/atmosphere circulations and continuous anthropogenic disturbances (increased populations of humans and domestic animals, socioeconomic instability, armed conflicts, displaced populations, unbalanced ecosystems, dispersal of resistant pathogens etc.) appear to be the major drivers of disease variability," and that "global warming at best [italics added] contributes."
By far and away the most significant cause of enhanced viral diseases in recent years has not been global warming. In fact, two whole classes of factors have dominated this aspect of human health and wellbeing during this period.
