what do we know? is this connected to climate change? >> that is what they are putting it together with. let me explain why that makes sense. if this climate change model works why it happens. we are talking about clear air turbulence. there is not a cloud in the sky all of the sudden the plane drops or goes up. there are loops in the jet stream that make you drop or go down depending on if you get into one. the jet stream currently is from about new york city back into central parts of france. that is where the jet stream is now without global warming. the forecast for this model says the jet stream will move to the north with global warming because there will be more warm air down here. if you move the jet stream to the north that is where the planes fly. so if the planes are flying in the new location of the jet stream therefore the planes will get into a bumpier flight.
