NY Times: ‘If the world is really warming up, how come it is so darned cold?’ – ‘A handful of scientists think the 50-degree temperatures in London…might be a consequence of climate change’
'Though the case is as yet unproven, a handful of scientists think the 50-degree temperatures in London and the frigid weather in Minneapolis might be a consequence of climate change. They contend the massive decline of sea ice in the Arctic has destabilized a weather pattern that normally keeps frigid air bottled up near the pole. That pattern is known as the polar vortex and its boundary is a fast-moving river of air called the jet stream. When the vortex weakens, the jet stream can develop big kinks, creating zones of extreme heat and cold.'
