The case for cloud-seeding

It is quite evident that most states in the world now conduct cloud seeding.

Cloud seeding is not all that new, in my youth it was common in the apple growing districts to shoot skyrockets above possible hail formations to disrupt the coalsecence of hail stones and reduce their impact on the crops. I believe the active chemical used was silver nitrate.

The more common chemical seen in modern cloud seeding is silver iodide. This nucleates rain drops which then gather electrostatically into cloud.

You will recognise them for their whispy-feathery appearance, which may or may not form into rain clouds - depending on the ambient humidity.

The presence of cloud seeding was first noticed by conspiracy theorists as "chemtrails", agianst which no official refutation was poffered - because no public agreement was sought for the practice.

I can think of some good reasons for cloud seeding - wildfire mittigation, cachement optimisation (water-supply dams) or even mittigation of global warming.

We don't know the justifications because we were not consulted. And the debate was never undertaken.

Let's have the debate now.

To kick it off, i will opose the practice and state as my opening arguement that: cloud seeding is vandalism of the sky.

Please state and argue your case:

For and against.

    Dec 15 2012: Hey Don Wesley, at risk of getting told off by TED staff cannot find a way of communicating with you other than this. Please look at my post regarding electrical composition of atmosphere and not being at all versed in that vocabulary what four electrical components are there in the balance of the atmospheric gases and water vapour that would assist in protecting the earth in the event of some kind of solar galactic discharge ? The four angels (energies) being personified in the Abrahamic religions as Michael, Gabriel, Ariel and the fourth, My personal e-mail is on my account. My son is as sensitive as me and has said he saw a glowing figure in his room about a month ago. In this age of scepticism it is so hard to communicate ideas that do not fit with mainstream. Thought it might be something to do with Adenine, Guanine, Cytosine and Thiamine four elements of DNA. Very fond of Jung, possibly because like me he was a bit wobbly at times but the 24 hour time frame we currently work in is a product of the industrial revolution with the synchronisation of railway timetables and the need to get the labourforce out of the fields and into the factories to produce goods. Sorry to sound so childish at times, wrestle with a limited technical vocabulary but family motto is With Fortitude and a kind heart so sorry to post on Mitch's conversation but want to hear your thoughts on this Don. Via my e-mail if not relevant to conversation thread. Until soon.

        Dec 15 2012: Thank you so much Don. In our local media this week a company wants to start a fracing operation here in the U.K. mainland. Fracing is well known for causing local earthquakes. Everyone argued the U.K, was seismically inactive but I remember an earthquake in the 1970s where Scotland 'rose' a little, having been depressed by the weight of glaciation during the last ice age. This is a real time argument. During the Industrial revolution many areas of England were mined for coal and tin etc. Many towns and villages are built over these sites, housing could literally disappear down abandoned mine shafts if fracing starts. I read in the last few months that the UK could start experiencing 'black outs' from 2015. The old coal fired power generators are being shut down as they are non-compliant with EU regulations. Sufficient nuclear generation plants were never built because of the 'green' lobby. Already in rural areas the local councils literally shut off the street lighting at night to save money. Electricity and gas have become incredibly expensive and we do not have the climate of somewhere like California or Oz or even my beloved NZ. Lets not talk politics but the ordinary people of the UK do not know what is going to hit them come next April. My local councillor said a recession may have been turned into a depression. Governance as suggested to Mitch in earlier post, Socrates said 'beware the anger of the mob'. Already riots in southern Europe, had one in London 2010. Technology only available to those who can afford it, used to use internet in my local library but that is not maintained due to cost cuts and all the libraries set up by Carnegie closed by local councils too. Apathy, ignorance and avarice already here. This is going to take a second post, sorry Mitch.
