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.
Local studies
A few local studies also support the value of cloud seeding. One study conducted in a farming region in the central United States, for example, directly monitored crop damage due to hail. The study found that in an area where cloud seeding was used there was reduced hail damage compared to previous years
Recently, there has a ton of debates about the feasibility of the cloud seeding process in protecting crops from hail in the United States. <pwa data-pwa-id="pwa-431697899854EA10174150F42A1D8174" data-pwa-rule-id="READABILITY_384" data-pwa-category="style" data-pwa-hint="Readability may be enhanced by using: According" data-pwa-suggestions="According" data-pwa-heavy="false" data-pwa-dictionary-word="More specifically, according" class="pwa-mark pwa-mark-done">More specifically, according</pwa> to the reading passage, the writer puts forth the idea that there are three pieces of evidence confirm the effectiveness of the cloud seeding. In the listening passage, the lecturer is quick to point out there are some serious flaws in the writer's claims. The professor believes that there are some questions on each argument made in the reading passage. <pwa data-pwa-id="pwa-042BD1830AB880209B1D732305EA8FCD" data-pwa-rule-id="READABILITY_814" data-pwa-category="style" data-pwa-hint="Readability may be enhanced by using: She" data-pwa-suggestions="She" data-pwa-heavy="false" data-pwa-dictionary-word="Additionally, she" class="pwa-mark pwa-mark-done">Additionally, she</pwa> addresses the trouble with each point made in the reading text.

Some professionals in the same field, however, stand in a firm the opposition to this claim. In the listening, such as, the professor states that in the real-life could seeding process prevents any precipitation (rain and snow). She <pwa data-pwa-id="pwa-4CD2819D7329453D3B71D064B8465B0E" data-pwa-rule-id="READABILITY_1169" data-pwa-category="style" data-pwa-hint="Readability may be enhanced by using: says" data-pwa-suggestions="says" data-pwa-heavy="false" data-pwa-dictionary-word="goes on to say" class="pwa-mark pwa-mark-done">goes on to say</pwa> that this process would cause death for crops because of the drought.
One group of scholars, represented by the writer, thinks <pwa data-pwa-id="pwa-83B473C3D91F9143D43C77787333CAA9" data-pwa-rule-id="READABILITY_2834" data-pwa-category="style" data-pwa-hint="The word 'that' can often be omitted here" data-pwa-suggestions="(omit)" data-pwa-heavy="false" data-pwa-dictionary-word="that " class="pwa-mark pwa-mark-done">that </pwa>using the cloud seeding in Asian countries has shown successful results. <pwa data-pwa-id="pwa-DA295FBEA75B12011C2B26FC9D1FBE5D" data-pwa-rule-id="READABILITY_242" data-pwa-category="style" data-pwa-hint="Readability may be enhanced by using: Though" data-pwa-suggestions="Though" data-pwa-heavy="false" data-pwa-dictionary-word="Of course, though" class="pwa-mark pwa-mark-done">Of course, though</pwa>, not all experts in this field believe this is right. Again, the speaker specifically addresses this point when he says that in Asian counties, they have used the cloud seeding in cities that have a high level of air pollution. However, pollutants in the air are a favorable condition for cloud seeding.
Finally, the author wraps his argument by positing that a study from local areas has proved the effectiveness of the cloud seeding process. <pwa data-pwa-id="pwa-54263D2E9F2103601F76585DCD104D11" data-pwa-rule-id="READABILITY_446" data-pwa-category="style" data-pwa-hint="Readability may be enhanced by using: The" data-pwa-suggestions="The" data-pwa-heavy="false" data-pwa-dictionary-word="Not surprisingly, the" class="pwa-mark pwa-mark-done">Not surprisingly, the</pwa> lecturer takes this issue with his claim by contending that the reduction of hail damage resulted from a natural variation of the weather and not from the cloud seeding.
