气候变化是国际社会公认的最主要的全球性环境问题之一,也是当今科学研究关注的焦点。气候变化影响粮食与所有农作物生产,一项研究指出,气候变暖将影响我国粮食安全和主要农作物生产,有利有弊。但相对于利,弊有更强的不确定性。 Climate change is one of the most recognized global environmental problems recognized by the international community and is also the focus of current scientific research. Climate change affects the production of food and all crops.

But relative to the advantages and disadvantages there is more uncertainty.
