So is the sun getting bigger and hotter and thus we need to spray chemicals in the atmosphere for protection OR are rogue governments trying to deliberately poison us
You can almost say kids studied them.
And when I was a kid contrails did NOT last anywhere near as long as thicker ones last today.
I see tic tac toes in the sky sometimes, there were never any tic tac toes in the sky when I was a kid
An aeronautical chart is a map designed to assist in navigation of aircraft, much as nautical charts do for watercraft, or a roadmap for drivers. Using these charts and other tools, pilots are able to determine their position, safe altitude, best route to a destination, navigation aids along the way, alternative landing areas in case of an in-flight emergency, and other useful information such as radio frequencies and airspace boundaries.
There are charts for all land masses on Earth, and long-distance charts for trans-oceanic travel.
Specific charts are used for each phase of a flight and may vary from a map of a particular airport facility to an overview of the instrument routes covering an entire continent (e.g., global navigation charts), and many types in between.
I said a contrail left by ONE PLANE did not last nearly as long as one contrail left by today's planes.
I am talking about one contrail trail left by ONE plane.
Jet streams are caused by a combination of a planet's rotation on its axis and atmospheric heating (by solar radiation and, on some planets other than Earth, internal heat). Jet streams form near boundaries of adjacent air masses with significant differences in temperature, such as the polar region and the warmer air towards the equator.
Meteorologists use the location of some of the jet streams as an aid in weather forecasting. The main commercial relevance of the jet streams is in air travel, as flight time can be dramatically affected by either flying with the flow or against the flow of a jet stream. Clear-air turbulence, a potential hazard to aircraft passenger safety, often is found in a jet stream's vicinity. One future benefit of jet streams could be to power airborne wind turbines.

btw aren't chemtrails taking this thread off subject, given that's it's about dispersal of acid rain causing sulphur in the stratosphere? And so-called chemtrails (if they exist) do not cause acid rain (else why would acid rain in the US and Europe be reducing?) and occur in the troposphere?
