Residents of Union County, New Jersey were apparently concerned yesterday morning when they noticed the sky was lit up with a strange glow. According to the New Jersey Star-Ledger, it turned out the glow was caused by the ConocoPhillips oil refinery in Linden, New Jersey "releasing excess gas." Sounds healthy! I don't know the exact ingredients of said gas, but one definition of refinery gas says the "common components include butanes, butylenes, methane, ethane, and ethylene. Some products found in refinery gas are subject to controls as a result of programs which are designed to address climate change." "N.J. residents baffled over strange glow in sky"
