How toxic is silver iodide?
The silver ion is among the most toxic of heavy metal ions, particularly to microorganisms and to fish. The ease with which Ag forms insoluble compounds, however, reduces its importance as an environmental contaminant. Ag is not likely to concentrate to harmful levels through either terrestrial or aquatic food chains.
When was Australia last El Nino?
Warmer temperatures
Prior to 2013 (a neutral ENSO year), Australia’s two warmest years for seasonal daytime temperatures for winter (2009 and 2002), spring (2006 and 2002), and summer (1982–83 and 1997–98) had all occurred during an El Niño.

What does silver iodide do to the human body?
Prolonged exposure to iodides may produce iodism in sensitive individuals. Symptoms could include skin rash, running nose and headache. Eyes: Flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids.
Is silver iodide cancerous?
The US Public Health Service claims there is a negligible environmental impact by cloud seeding. That said, silver iodide when studied in labs is a different story all together and is indeed toxic and dangerous. This same study says that silver is not known to be carcinogenic to humans.
Is 2022 an El Niño year?
WMO predicts first “triple-dip” La Niña of the century
The WMO El Niño/La Niña Update predicts the continuation of the current La Niña over the next six months, with a 70% chance in September-November 2022 but gradually decreasing to 55% in December-February 2022/2023. It started in September 2020.
Is El Niño wet or dry?
El Niños often lead to drier conditions over large parts of Australia, while La Niñas tend to enhance rainfall over much of the continent.

Has the Earth ever been warmer than it is today?
Even after those first scorching millennia, however, the planet has often been much warmer than it is now. One of the warmest times was during the geologic period known as the Neoproterozoic, between 600 and 800 million years ago. Conditions were also frequently sweltering between 500 million and 250 million years ago.

What are the disadvantages 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.
What happens when silver iodide is exposed to sunlight?
When silver iodide Crystal are exposed to sunlight the silver ion gets reduced to silver metal and iodide ions are oxidized to iodine gas. 2 moles of Silver iodide gives 2 moles of silver metal and 1 mole of iodine gas. Application of this reaction is in silver based photography.
What happens if you have too much silver in your body?
When taken by mouth, silver builds up in your body. Over months to years, this can result in a blue-gray discoloration of your skin, eyes, internal organs, nails and gums. Doctors call this argyria (ahr-JIR-e-uh). It’s usually permanent.
Is La Niña wet or dry?
What is La Niña? La Niña is a climate pattern that usually delivers more dry days across the southern third of the US. Its drought-producing effects are especially pronounced in the south-west, but the phenomenon will also contribute to higher risks of hurricanes as the winds help the storms build. .
Is El Niño worse than La Niña?
