That article's pint in the near term is dependent on a warmer Winter rather than a warm one, so shorting nat gas right now is a very high risk position to take (especially after DGAZ run this week and as we are about to enter withdrawals as early as next week's inventory report).
Article makes a valid point about longer term nat gas production being large, which I've always understood and happen to agree with, of course. But that should not distract from the focus in the shorter term that we likely will have another very cold winter, while going into withdrawal season having storage levels at 5 year lows. We haven't even made up from last Winter's withdrawals yet.
