It’s hard to say. While we can’t change daily temperatures, there’s some evidence that we can modify precipitation with a method called cloud seeding. The United States uses cloud seeding to alleviate droughts, induce snowfall near ski resorts, and even reduce hailstone size and fog.A crash course on cloud seeding: Usually by plane, but occasionally by other means like chimneys or even cannons, certain chemical compounds are introduced into clouds. The hope is that these compoundsâ€â€the most popular being silver iodideâ€â€turn water droplets into ice crystals, making them heavy enough to fall from the clouds. In the cold, they’ll be snowflakes; in warmer temperatures, they’ll melt into raindrops.Further, we seed fog with dry ice to increase visib
