Editor's letter [Opinion Editorial]

Are you reading this on a plane on your way to sunnier climes? Have you noticed the ride is a bit bumpier than it used to be? In this month's cover story we hear how global warming is creating more turbulence on transatlantic flights. Does that matter?

It also means higher fuel consumption and more carbon emissions.
