Shortages of gas for heating have hit the nation’s most important city: New York.

Following moves by Gov. Andrew Cuomo and New Jersey Gov. Phil Murphy to nix a pipeline that could deliver vital gas supplies to the city and Long Island, National Grid can no longer offer new gas hookups or additional service for current customers.

“If you’re looking to expand your natural gas service in Brooklyn, Queens or Long Island, we will not be able to meet your request,” unless both states reverse their decisions and OK the pipeline, the utility warns. Con Ed may have to turn away customers, too.

The govs nixed the pipelines in a pander to climate-change radicals. Yet the shortage won’t only hit well-off developers and businesses: It’ll also threaten projects meant for low- and middle-income New Yorkers.

A local group called Heartshare, which assists New York’s needy with heating costs, is nervous. Its vice president for energy programs, Joe Guarinello, says it’s written local congressmen in support of the pipeline.

“Right now, gas is the most inexpensive and the cleanest for heating homes in our area,” he notes. “We’d like to make sure that the people we assist, both the disabled and the economically stressed,” can continue to benefit from it.

The nuttiest part: These shortages are by no means unintended; they’re exactly what climate-change radicals want — a cutoff in fossil fuel supplies, whatever the consequences. They don’t care that there’s no good substitute now, or who suffers.

Don’t give up yet. The pipeline builder refiled its applications for permits. Sanity can yet prevail — but only if Cuomo and Murphy care about New York’s future.
