Because alleged expert Stu Ostro says that global warming is increasing the atmosphere's thickness?: English major Chris Mooney explains why global warming allegedly caused the intense winter in the UK that threatens to last throughout April

Climate Desk Live 06/06/13: The Alarming Science Behind Climate Change’s Increasingly Wild Weather | Mother Jones

[Chris Mooney] Join us for a joint Climate Desk Live and World Wildlife Fund (WWF) event moderated by Chris Mooney discussing the alarming science behind climate change's increasingly wild weather featuring senior Weather Channel meteorologist Stu Ostro and top climate researcher Jennifer Francis.
...
Stu Ostro is a senior meteorologist at the Weather Channel, and was a longtime climate change skeptic—until the devastating 2005 Atlantic hurricane season, when he started documenting hundreds of cases of extreme and unusual weather and the patterns associated with them, and became convinced that something is very off about the atmosphere.
...
Both are now leading voices in diagnosing the wild weather that the world has seen of late—most recently, an intense winter in the UK that threatens to last throughout April.
...
Ostro's observations suggest that global warming is increasing the atmosphere's thickness, leading to stronger and more persistent ridges of high pressure, which in turn are a key to temperature, rainfall, and snowfall extremes and topsy-turvy weather patterns like we've had in recent years.
