Global warming is projected to shift thermal thresholds northward, significantly increasing the agricultural climate suitability of high-latitude boreal and Arctic-adjacent regions.
The retrieved literature consistently supports the claim that warming temperatures facilitate a northward shift in agricultural climate zones and crop suitability ranges. Papers [0], [1], [6], and [11] explicitly document or model poleward expansions of agricultural viability and crop ranges driven by climate change. None of the papers refute the core premise that warming enables northward agricultural potential, though some papers (like [6]) note additional localized soil or water constraints.
