Hail—pieces of ice that form and fall from clouds instead of snow or rain—has always been a problem for farmers in some areas of the United States. Hail pellets can fall with great force and destroy crops in the field. Over the last few decades, a method of reducing hail, called "cloud seeding," has been tried. In cloud seeding, the chemical silver iodide is sprayed on storm clouds from an airplane. This makes the clouds produce harmless rain or snow instead of hail. Several pieces of evidence suggest that cloud seeding has been effective in protecting crops from hail.
Laboratory experiments
Experiments in the laboratory support the idea that cloud seeding is effective. Hail usually forms water vapor that is close to the freezing point However, when experimenters added silver iodide to cold water vapor in the laboratory, they often observed light snow forming instead of hail pellets.
Evidence from Asia
There is evidence about the effectiveness of cloud seeding from several countries around the world. In some Asian countries, for example, cloud seeding has been successfully used to control precipitation in urban areas. These positive results suggest that cloud seeding should also be effective in protecting fields and farms in the United States.
The reading the lecture are both about the cloud seeding in United States. The author of the passage feels that cloud seeding is efffective protection against hail and provides with different evidences for the same. The lecturer challenges the claims made by the author. He is of the opinion that these evidences are not convincing.
To begin with, the author argues that laboratory experiments done by adding silver iodide to cold water vapour prevent hail formation. The Article mentions that silver iodide prevents precipitation from clouds by sealing water. She further claims that this will lead to no rain, consequently, drought conditions will occur damaging crops for some other reason such as lack of water.
Secondly, the writer claims that cloud seeding provided positive results in controlling precipitation in urban areas and suggests to use cloud seeding in United states farms and fields as a protective shield. The speaker, however, rebuts this by mentioning that urban areas experience air pollution due to cars and industries. She elaborates on this that, silver iodide interarcting with pollution might have controlled precipitation, but such changes may not occur in unpolluted areas like farming fileds in United States.
Finally, the author professed a study conducted in central United States's farming region where cloud seeding reduced hail damage as compared earlier years. In contrast, the author rebuks this by stating that change has occured in whole region. She notes that natural change in local region's climate for particular year might be the resaon. She adds that cloud seeding has nothing to do with this.
