    If it's less than 20 years old the expanding agent in the insulation was probably an HCFC or an HFC. Before that, CFCs were common.

    It's raining here for the first time in four months.

    It usually doesn't rain until January.

    They say El Nio might bring heavy rains later this year.

    I don't care.
