NYT’s Revkin on Arctic sea ice: ‘I wouldn’t bet that ‘the Arctic is all but certain to be virtually ice free within two decades,’ as some have proposed’
Revkin: 'Is this a situation that is appropriately described as a 'death spiral'? Not by my standards' -- 'There's plenty of year-to-year, & even decade-to-decade variability to complicate things'
Revkin: ‘And variations in the thickness and extent of sea ice cloaking the Arctic Ocean are driven by yet another set of complicating factors, ranging from long-term shifts in atmospheric pressure patterns to events as close-focus as the potent Arctic superstorm‘
