Cloud Seeding



Did you ever think it would be possible to control the weather?
well now it is, scientist figured out how to make it rain if it is ever necessary.

Could seeding is a type of international weather modification.
By adding dry ice and silver iodine into a could by plane or cannon they expand into gasses and cause the could to lower in temperature, changing the amount of precipitation . This may sound easy but there are many things that decide if a could is acceptable for could seeding or not, scientists have to keep in mind the timing of the could and the temperatures of the could because the chemicals can only affect the temperature to a certain point. There are two diff rent types of could seeding which are based on temperature of the could. Glaciogenic could seeding is preferring to cooler colds, which is when dry ice and silver iodine are added. The second type of could seeding is for warmer clouds which involves hygroscopic compounds such as salt, urea and ammonia nitrate.




Good for the people or bad for politics?


pros.


we can get rain where we need it when we need it.


increased rain means more crops and more food.


More food means the economy will be better.


cons,


are the chemicals safe to deal with long term.
what if we cant control the amount of rain.


is the coast worth it ?


Now that you know some of the background on cloud seeding what is your opinion?
