Read the following passage carefully:
For decades, paleoclimatologists attributed the mid-Holocene thermal maximum primarily to orbital forcing, asserting that peak insolation directly governed global surface temperature shifts. Under this prevailing view, early climate simulations presumed a synchronous, planet-wide thermal response to astronomical cycles.
However, recent multi-proxy reconstructions from high-latitude marine sediments revealed pronounced thermal asymmetries that orbital models failed to predict. To account for these discrepancies, dynamic vegetation feedback theories emerged, contending that land-surface albedo changes amplified localized warming independently of direct solar radiation.
Most recently, synthesis studies have demonstrated that these proxy anomalies stem from seasonal recording biases inherent to marine planktonic organisms rather than true mean-annual temperature shifts. By accounting for this proxy seasonality, researchers reconciled the divergent models, establishing that orbital forcing dictates the foundational climate trajectory while vegetation dynamics act strictly as a secondary, seasonally constrained modifier.
Below are three descriptions of the structural functions performed by the paragraphs in the passage. Arrange the descriptions in the correct sequential order matching Paragraph 1, Paragraph 2, and Paragraph 3.
- 1Outlines a long-standing scientific consensus and its underlying theoretical premise regarding a global phenomenon.
- 2Presents observational data that conflicts with the established paradigm and details a competing explanatory hypothesis.
- 3Resolves the theoretical contradiction by exposing a methodological artifact, thereby establishing a qualified synthesis of both views.
