Many models of ocean chemistry and biology predict that as the ocean surface warms in response to increasing atmospheric greenhouse gases, phytoplankton productivity will decline.

许多海洋化学和生物学模型预测，由于海洋表面变暖来应对大气中温室气体的增加，浮游植物的生产力会因此下降。

Some, including Dr Riebesell, suspect that these physical and chemical effects of warming may prove a greater driver of productivity change in the ocean than altered ph.

包括Riebesell博士在内的一些人士怀疑暖化带来的物理和化学因素对海洋里生产力的影响可能超过改变了的PH值。

"If in fact productivity is going down so much, the implication would be that less carbon capture and storage is happening in the open ocean," he said.

他说，“如果实际上浮游植物减少的这么多，那么其影响将会是更少的二氧化碳会被吸收从而在海上聚积起来。”
