What are the negative effects of cloud seeding?
Risks or concerns like unwanted ecological changes, ozone depletion, continued ocean acidification, erratic changes in rainfall patterns, rapid warming if seeding were to be stopped abruptly, airplane effects, to name a few, may just not be bad enough to override the imperative to keep temperatures down.
Does cloud seeding affect environment?
Published scientific literature shows no environmentally harmful effects from cloud seeding with silver-iodide aerosols. Samples of snow can be collected and sent to labs to analyze how much silver is in different layers of snowpack to determine effectiveness.
What caused Lynmouth flood?
The root cause of the flood was heavy rainfall associated with a low-pressure area that had formed over the Atlantic Ocean some days earlier. Similar floods had been recorded at Lynmouth in 1607 and 1796. After the 1952 disaster, Lynmouth village was rebuilt, including diverting the river around the village.
What chemicals are used in cloud seeding?
Most cloud seeding operations, including those run by DRI, use a compound called silver iodide (AgI) to aid in the formation of ice crystals. Silver iodide exists naturally in the environment at low concentrations, and is not known to be harmful to humans or wildlife.
How long does cloud seeding last?
Seeding effects can range from almost immediate to up to 30 minutes depending on the seeding delivery method (direct injection at cloud top, or base seeding – releasing seeding agent in the updraft below the cloud base).
How does cloud seeding affect the water cycle?
Cloud seeding is the process where substances like dry ice and silver iodide are put into clouds in an attempt to make precipitation fall. Cloud seeding has also been used to dissipate fog and weaken some storms.
What floods have happened in the UK?
2019–20 United Kingdom floods. The River Don in Doncaster, South Yorkshire overtops its banks on 8 November 2019; people had to be evacuated due to fear of the banks collapsing. Between November 2019 and February 2020, severe winter flooding occurred across the United Kingdom.
How many people died in the Lynmouth floods?
The disaster which occurred in and around the town of Lynmouth on the night of August 15th-16th 1952 remains, after 60 years, the worst river flood experienced in the UK. Over 100 buildings were destroyed and the final death toll reached 34.
Is silver iodide harmful?
Under the guidelines of the Clean Water Act by the EPA, silver iodide is considered a hazardous substance, a priority pollutant, and as a toxic pollutant. If the toxicity manifests in pollution and illnesses, the effects may not be reversible.
What are the advantages and disadvantages of cloud seeding?
Top 10 Cloud Seeding Pros & Cons – Summary List
| Cloud Seeding Pros | Cloud Seeding Cons |
|---|---|
| Cloud seeding can help to reduce poverty | Can lead to air pollution |
| Cloud seeding can be applied locally | Cloud seeding can contribute to acid rain |

What is cloud seeding?
Cloud seeding is a part of weather modification (or engineering ). It relates to regulation of precipitation (both quantitatively and alteration of type) in a certain area.
Was there ever cloud seeding in Britain?
There is no mention of cloud seeding. But a 50-year-old radio broadcast unearthed by Radio 4 describes an aeronautical engineer and glider pilot, Alan Yates, working with Operation Cumulus at the time and flying over Bedfordshire, spraying quantities of salt.
Can cloud seeding help Indonesia’s Jakarta flood-hit capital?
Indonesian authorities are turning to the technique of cloud seeding to try to stop more rain falling in the flood-hit capital Jakarta. Planes have been sent to inject chemicals into clouds in an effort to alter precipitation. Jakarta and surrounding districts have struggled to cope since a storm on New Year’s Eve left large areas underwater.
Can clouds be artificially seeded to fasten the process of rainfall?
There is a particular kind of clouds that can be artificially seeded in order to fasten the process of rainfall and they are thunder clouds. Cloud seeding is a part of weather modification (or engineering ). It relates to regulation of precipitation (both quantitatively and alteration of type) in a certain area.
