. . . contrail cirrus clouds are the single largest source of the aviation industry’s contribution to climate change, far outpacing the impact of aircraft carbon dioxide emissions. Despite this, however, their role is often overlooked and is not included in the United Nation’s upcoming Carbon Offsetting Scheme for International Aviation (Corsia).
. . . research used the post‐9/11 flight groundings in 2001 to detect a contrail effect on diurnal temperature range across the United States. The removal of contrails was found to have increased daytime high temperatures and decreased nighttime low temperatures.
Here we use a very high density network of meteorological stations across the United Kingdom to assess the importance of contrails on diurnal temperature range during a more recent flight grounding following the Eyjafjallajökull volcanic eruption of 2010. We find that subtle, but substantial, temperature shifts related to contrails may have been overprinted by larger shifts in weather systems passing over the United Kingdom.

If they are ostracized by 97% of climate scientists, then we'll know they may be on to something.
The natural CO2 flux to and from oceans and land plants amounts to approximately 210 gigatons of carbon annually. Man currently causes about 8 gigatons of carbon to be injected into the atmosphere, about 4% of the natural annual flux. There are estimates that about half of man's emissions are taken up by nature.

There are ...what, 6+ Billion Humans living in the Northern Hemisphere of our planet, maybe a billion and a half humans in the Southern Hemisphere.
As the humans of the Northern Hemisphere contribute around 90+% of All human created pollution....it would figure that the Northern Hemisphere is 90 times dirtier, hotter, unlivable etc etc, than us clean people in the South.
Is that the case?
Is the Northern Hemisphere practically unlivable for life on Earth, compared to the South, all because of humans?
Yet, the Southern Hemisphere is still tied up in this conspiracy, even though our contribution to human pollution is miniscule.....oh well, that's life.

What is wrong with all of you?
Who cares about how much impact man has on the climate? What does that have to do with implementing the biggest financial scheme ever proposed?
Look, the "right" people need to get rich with carbon trading, carbon taxes, and carbon regulations so just stop fighting it and pay the hell up.
