I came across this report and wanted to share it with you. The worry is that PERSISTENT CONTRAILS are causing major problems with our atmosphere, with or without toxins.

Contrails can affect the global atmospheric radiation budget by increasing planetary albedo and reducing infrared emission. The total amount of the global radiative forcing depends on several poorly known factors including the global mean contrail optical depth,cloud microphysics and the frequency of contrail occurrence. Because air traffic is expected to grow by 2to 5% annually (Minnis et al., 1999), it is becoming more important to estimate contrail frequency accurately. Earlier estimates of global contrail coverage are based on empirically tuned models of contrail formation using a combination of European Centre for Medium Range Weather Forecast (ECMWF) meteorological analyses,criteria for contrail formation, and simplified distributions of fuel usage (Sausen et al., 1998). These models of contrail generation were normalized to satellite-based estimates of linear contrail coverage taken over the North Atlantic and central Europe (Bakan et al., 1994).However, recent estimates of contrail coverage over these areas from an objective detection algorithm (Mannstein et al., 1999; Meyer et al., 2001) are significantly smaller than those given by Bakan et al.(1994). Additionally, a comparison of the empiricalcontrail coverage of Sausen et al. (1998) with contrailcoverage analyses of Advanced Very High ResolutionRadiometer (AVHRR) data taken over the continental United States (Palikonda et al., 1999) show they compare well in overall magnitude of coverage, but differ in spatial distribution. These results illustrate the current uncertainty in contrail coverage estimation, a key component in the determination of contrail climate effects http://www.google.co.uk/search?q=cache:H0G6X2DTCJAC:www-pm.larc.nasa.gov/sass/pub/conference/JP1.15.duda.arams.02.pdf+persistent+contrail&hl=en&ie=UTF-8

So what about a debate on the dangers of PC's and effort to make our politicians and friends more aware of PERSISTENT contrails in order to stimulate action. Without having to try and convince people of all the other evil things chemtrails are.

I witness chemtrail spraying almost everyday in the North of The United Kingdom. I know they are chemtrails, but I want people to listen to a problem they can deal with.

You don't understand the significance when we manuipulate weather and thus explains your comment.

Did you read the link and understand the significance?

Trails in the sky are dangerous to all life and the symbiotic relationship of the seas and clouds to cool our planet.

My point is that this gives those who have difficulty building a broad coalition against Chemtrails can also use Persisant contrails to start discussions with the lay man. Can by simply pointing out the dangerers of PC's and then move into the darker area of Chemtrails.

PERTURBING THE CLIMATE

To really comprehend just how delicately balanced our fragile planet is we need to consider the astrophysics converging on our region of space. We have to look into deep time and space. Then it becomes easier to see how the slightest perturbations to our atmosphere can cause dramatic rifts in the course of our geophysical destiny. Many complex forces are already impacting the Earth, particularly our global weather patterns. Looking at the broadest scale, there is a galactic ice age threat from supernovas, whose cosmic rays create clouds when they hit our atmosphere, cooling it. Also, the solar system is passing through the densest portion of the Milk Way Galaxy, a roughly 30-million-year cycle.

This dense molecular cloud and fluctuating galactic tidal forces of distant matter can destabilize comets in the Oort cloud and send them hurtling toward the planets and sun. This rain of small comets called impact surges, (2/3 from disk tides and 1/3 from distant matter tides), is influential in the pulsing and advancing of ice sheets over millennia and implicated in mass extinctions. It affects the oceanic heat pump (with a rain of fresh water) that acts as a global ocean conveyor. This salt pump moves warm water into northern climes, like the eastern seaboard and Europe, keeping them habitable, while cooling the tropics. Its collapse would mean that warm, salty Gulf Stream water would no longer move north, facilitating another Ice Age. http://www.geocities.com/nwbotanicals1/index.htm

PDXPilot if you are happy with man made clouds and the massive effect it has on cooling the planet you are further away from your essence than I thought.

We need to live in harmony with our planet. Chemtrails and contrails are speeding up the process of doom and you seem to be an advocator of this?

I have been slapped around a bit here for holding that the name -- chemtrails or contrails or chaff or whatever -- does not define the level of toxicity to living beings. There are no doubt sprayed substances which are not trails but which should concern us. Anything which isn't water when it is supposed to be water should be a concern. Reminding us of the name of this website does not make contrails and other dispersed substances less toxic.
