<strong>ASTRONOMY</strong> <strong>CONTRAILS</strong> <strong>JET</strong> <strong>AVIATION</strong> CIRRUS GLOBAL WARMING AIR ...<br />

6. Danish Society for the Conservation <strong>of</strong> Nature: "Luk naturen ind i din stue: Danmark er ikke et stort land. Ca. 43.000 km2. Til gengæld har vi en kystlinje på ikke<br />

mindre end 7.300 km. En strækning, som svarer til afstanden mellem Danmark og det sydlige Angola i Afrika. Alligevel er naturen begrænset i Danmark. Trafikstøj og<br />

hundeglam rumler altid i baggrunden, mens flyvemaskiner trækker deres kondensstriber henover himmelbuen": http://www.dn.dk/...<br />

11. A ground-based observation <strong>of</strong> an AWACS contrail from September 21, 2000, over Jutland, Denmark: "Mystiske skyer over Jylland Et par bekymrede mennesker fra<br />

midt Jylland kontaktede redaktionen og forklarede om mystiske jetstriber på himlen. Hurtigt fik jeg fat i en bil og ud for at se efter. Ganske rigtigt så jetstriberne sjove<br />

ud, og mindede mest af alt om en SAS pilot der var faldet i søvn over styrepinden i sit fly, og nu lå og fløj rundt i cirkler. Jeg vejrede nu sensationen: var de mystiske<br />

korncirkler på markerne nu også et luftfænomen ? Nej naturligvis havde dette fænomen en naturlig forklaring. Det drejede sig om striber efter et stort tankfly som lå og<br />

kredsede over Jylland i forbindelse med en netop overstået flyøvelse i Karup. Men flot så det ud alligevel": http://plr.hok.dk/...<br />

12. Danish Environment & Energy Newsletter from the Ministry <strong>of</strong> Environment and Energy: "New climate research indicates that aircraft emissions <strong>of</strong> CO2 at great<br />

heights have three times as great a climatic effect as corresponding CO2 emissions at ground level. Air transport must therefore be considered a major contributor to<br />

climate change. If this development continues, moreover, air transport could one day end up contributing more than road transport": http://www.mex.dk/...<br />

8. Olivier Boucher: "Condensation trails (or contrails) which appear in the sky behind an aircraft are the most visible, and maybe the most significant, effect <strong>of</strong> aviation on<br />

the atmosphere and Earth's climate. Here we present the classical theory <strong>of</strong> contrail formation, as well as recent work on the microphysical and optical properties <strong>of</strong><br />

contrails and their potential impact on cirrus cloudiness and the radiation budget": http://www.smf.asso.fr/...<br />

9. French elementary question on contrails: "La grande majorité des nuages sont formés naturellement quand l'air humide monte et se refroidit . Toutefois , les avions avec<br />

leurs traînées de condensation (contrails) produisent une petite fraction de nuages": http://www.ac-grenoble.fr/...<br />
