I'm not sure about global warming.
I was pregnant during an El Niño year. The weather was insane. Akron was warm and sunny for most of the winter while kids in Florida and Texas were playing in snow.
Dick Goddard, the Cleveland weatherman, held up a newspaper from an El Niño year many decades ago before people understood this particular weather pattern. The page was filled with hysterical and ominous warnings and speculated that airplanes and radio waves were causing the crazy weather.
So maybe the global warming scare is a overreaction to climate changes that would be happening even if we weren't here.
I'm leaning towards believing in global warming now, but I'm not convinced. Either way we need to clean up our act and find alternatives to oil, which isn't going to happen until we force the oil industry to release its stranglehold on our economy.
