“我们是本着为公共卫生谋福利才清理悬浮微粒的，但就气候状况而言，可能将自己置于更麻烦的境地。”马霍瓦尔德说道。

"As we clean up the aerosols, which we really want to do for public health reasons, we are going to be perhaps causing ourselves more trouble in terms of the climate situation," Mahowald says.

美国康奈尔大学的一位气候学家娜塔莉·马霍瓦尔德表示，迄今为止，科学家们一直都在设法获悉悬浮微粒在空中有什么作用。

Natalie Mahowald, a climate researcher at Cornell University, says so far, scientists have mostly tried to understand what those aerosols do while they're actually in the air.
