The effect of dust on cloud properties is to inhibit precipitation,

The reduction of precipitation from clouds affected by desert dust can cause drier soil, which in turn raises more dust, thus providing a possible feedback loop to further decrease precipitation.

The impact of pollution on these clouds is sufficiently strong to completely shut off precipitation from them.

They're here to bash on Americans and come here and take our jobs and properties.

Now I did the very first step, taking the clearest possible case, to tell us all: 'Hey, it is happening without any doubt. Now let's go in earnest to investigate that,'

Unfortunately, my satellite measurements reveal that almost all pollution sources produce many small aerosols that work to reduce the size of the cloud droplets, thus the precipitation.
