		<description>No, I&#039;m almost certain Michael is just trolling, to get an argument going for fun. There is no way someone could believe that sound waves of compressed air are somehow also a part of the electromagnetic spectrum &lt;i&gt;overlapping&lt;/i&gt; radio waves. That would literally take a 10 year old 30 seconds to research and disprove.

One of my favourites was in there though, the &lt;i&gt;don&#039;t try to blind people with science&lt;/i&gt; line. If the science is wrong, but sounds convincing, then that phrase applies. But if the science is right, then falling back on this defence simply advertises to all that you lack the expertise or perhaps juat the patience to understand it.</description>

		<description>Michael, when you lose your temper and go into a rant it probably indicates that you don&#039;t have a sound basis for your opinions, and that you are feeling threatened by their arguments, and that you are &quot;squirting ink&quot; to hide that fact from both them and yourself.</description>

		<description>&quot;I understood that the minimum height for these contrails was 30,000 feet &quot;

It is not true.
Where did you get that idea from?
Please have a read of all the articles on the left side of this page under the word &quot;Articles&quot;
They deal with many different aspects of contrail formation such as ground level contrails.
http://contrailscience.com/ground-level-contrails/
http://www.youtube.com/watch?v=UtISR1_OzSQ

&quot;Presuming they are vapour trails ,why have we not noticed them earlier&#039;
People noticed them over 70 years ago, that&#039;s pretty early. Perhaps you mean you yourself have not noticed them.  Lots of other people have noticed them and documented them in detail.

&quot;You can actually see them criss crossing the sky in a checkerboard fashion as though they were being deliberately put there for some reason.&quot;

http://upload.wikimedia.org/wikipedia/commons/f/fb/IFR_high_altitude_en_route_chart_section_-_Teres_-_UZ6_airway_and_Cachimbo_airbase.jpg

Planes fly in different directions and their paths cross. Their paths thus form criss cross grids for the exact same reason that roads form criss cross checkerboard grids.
Notice how roads look as though they were put there for some reason? Obviously It&#039;s so people can drive from place to place.  
Flight paths are specified for the same purpose to fly from place to place but without you knowing about the enroute high navigation maps that specify those paths, you&#039;ll only notice the paths if planes leave contrails.

&quot;they do not go away but actually increase in volume and become massive cirrus type clouds.&quot;

Yes, that is normal and has been documented as such many decades  ago:
‪Extract from &#039;&#039;Flight To Arras&#039;&#039; Published  1943‬
‪&#039;&#039;The German on the ground knows us by the pearly white scarf which every plane flying at high altitude trails behind like a bridal veil. The disturbance created by our meteoric flight crystallizes the watery vapor in the atmosphere.﻿ We unwind behind us a cirrus of icicles. If the atmospheric conditions are favorable to the formation of clouds, our wake will thicken bit by bit and become an evening cloud over the countryside&#039;&#039;.‬</description>

		<description>All i know is that only in recent years have i seen so many contrails and aircraft have been around for ages. When i do look up in the sky there seem to be a hell of a lot of these &#039;contrails&#039; and they do not go away but actually increase in volume and become massive cirrus type clouds.
I understood that the minimum height for these contrails was 30,000 feet and apparently they appear much, much lower than that. You can actually see them criss crossing the sky in a checkerboard fashion as though they were being deliberately put there for some reason.
Presuming they are vapour trails ,why have we  not noticed them earlier, and why do they always last so long and spread to cover the whole sky. We used to get such clear blue skies and now its always messed up with these so called &#039;contrails&#039;. That sounds like the righy word for me. I am now certain they are indeed chemical trails and those people who get angry at the suggestion of chemtrails and contemptuous of others who say they are may well be people who have interests in Carbon Credits too.
We often forget that if we are talking about &#039;Global Warming&#039; that the Sun is the biggest and usually the one and only &#039;culprit&#039;. Why do people think that the Sun has always been the same?Why do they presume that climate always remains the same. Neither the Sun nor the Climate has ever been that &#039;Constant&#039;.
Why on Earth do they think that human beings can solve such a Global Problem? Its outright arrogance to even contemplate it. Even if you got rid of all the CO2 it would not make an iota of difference.
If people are going to make outlandish claims and base it on specious pseudo science then maybe they can tell the future? Do they put themselves into the category of fortune tellers too?
Even the weathermen cannot give us a consistent accurate weather forecast let alone anything else.
You can fool some of the people some of the time. some of the people all of the time, but you can&#039;t fool all the people all of the time.
I always trust my gut instincts and they say that All Politicians are Liars, and the General Public are 
Fools because they vote for them.  The phrase ;&quot;Follow the Money says where its at.
Who was that person who once said they would tax the very air you breathe  if you let them?
Well Folks ; You have let them and you have believe the Liars.
More Fool You and more fool the rest of us for allowing  fools like you who believe in Chemtrails being Vapour trails to convince us. They are definitely Chemtrails and i don &#039;t need some jumped up tosspot to tell me otherwise by blinding me with science.</description>
