If you’re determined to summit and ski remote Mont Forel, the second-highest peak in Greenland, knowing that the aircraft-fueled expedition will pump carbon into the atmosphere, you might mitigate the guilty pleasure by bringing along a climate scientist. This renders Guilt Trip into a perfect Mountainfilm package, offering a dose of adrenaline and wonder at the staggering beauty of the natural world, but not without with the science of climate change, seasoned with guilt over our own contribution to making April in Greenland downright hot. That the balmy weather and rapidly melting ice partially thwart both scientific research and adventure travel is a bitter irony lost on no one.
