Passage:
In analyzing the economic shocks of mid-seventeenth-century Europe, historians long attributed the widespread agricultural collapses of the 1640s primarily to localized agrarian mismanagement and protracted military conflicts such as the Thirty Years' War. However, recent interdisciplinary research combining dendroclimatology and ice-core geochemistry has forced a reevaluation of these disruptions. Dendrochronological data from subalpine conifer rings reveal unprecedented reductions in latewood density during 1641 and 1642, indicative of severe, unseasonal summer cooling. Simultaneously, polar ice cores from Greenland show distinct spikes in sulfate aerosol concentrations dating precisely to late 1640, pointing to a massive tropical volcanic eruption that injected light-reflecting sulfur compounds into the stratosphere.
While conventional historical accounts assumed that localized crop failures were exacerbated solely by army movements destroying fields, synthesizing high-resolution physical proxy records with regional grain price registers demonstrates a more complex systemic interaction. In regions entirely untouched by military activity, such as southern Scandinavia, cereal yields declined by over 40 percent in 1642, coinciding with the temperature nadir calculated from tree-ring density. Crucially, price convergence data show that shipping lanes in the Baltic Sea froze several weeks earlier than normal during the winters of 1641–1643. Although some economic historians hypothesized that regional grain market integration would normally buffer localized harvest shortfalls through maritime trade, this unexpected prolonged freezing severed key supply corridors, preventing surplus grain from reaching vulnerable urban markets. Thus, the physical evidence indicates that atmospheric phenomena initiated a cascade that crippled both agricultural output and the logistical infrastructure intended to redistribute relief supplies.
Based on the passage, evaluate whether the following statement is TRUE or FALSE:
"The physical proxy evidence presented in the passage supports the inference that the unusually early winter freezing of Baltic shipping corridors in 1641–1643 was triggered by the same atmospheric perturbation responsible for the decreased latewood density in subalpine conifers during 1641 and 1642."
