Shared Socio-economic Pathways and Representative Concentration Pathways selected for modeling.

SSP & RCP	Description
SSP126 (Sustainability Scenario)	Assumed that global efforts toward sustainable development are actively promoted, with strong climate policies and technological innovations to reduce greenhouse gas emissions, promote clean energy, and enhance resource efficiency. It emphasizes global cooperation and social equity, resulting in low emission levels.
SSP245 (Middle of the Road Scenario)	Assumed that global efforts toward sustainable development are actively promoted, with strong climate policies and technological innovations to reduce greenhouse gas emissions, promote clean energy, and enhance resource efficiency. It emphasizes global cooperation and social equity, resulting in low emission levels.
SSP370 (High Emission Scenario)	Assumed continued economic growth globally, but with insufficient climate policies. Greenhouse gas emissions remain high, and the energy structure is heavily reliant on fossil fuels. Climate change mitigation is inadequate, global cooperation is weak, and the impacts of climate change are severe.
SSP585 (High Emission Scenario)	Assumed that global efforts to reduce emissions are ineffective, with continued reliance on fossil fuels and extremely high greenhouse gas emissions. Climate policies and international cooperation are lacking, and the impacts of climate change are severe, putting tremendous pressure on ecosystems and socio-economic systems.
