In the world of agriculture, as with popular medicine, the theory is to treat the symptom (in this case insect invasions) and to hope that by the time fix becomes ineffective wehavesomethingelse figured out to spray, engineer or swallow to re-bandaid the problem.
It means that if we overestimated the soil response to warming then we must have underestimated somethingelse dramatically because wehave a net effect of faster global warming.
