The Big Money is going towards disproving the results of climate change. But you have one point definite: climate change does occur, regardless of humans. The human factor, however, exacerbates the situation. Yes, volcanoes put pollution in the air and plays havoc with the weather. I recall when Mt. St. Helens erupted back in the early 80s. Warmest city in the northern hemisphere that winter? Juneau, Alaska. Heck, it affected where I live in the Great Lakes region. Where I live, about a 2 hour drive from Chicago, if temps that winter dropped below 32°, it was a rare occurrence. We had snow fall Thanksgiving evening, into the early hours so when we woke up, there was about 1½" of snow on the ground when we left my in-laws to head home. By 6PM, all the snow was gone and we didn't see another snowflake until the morning of Groundhogs Day. I was listening to the radio as I'd just gotten off work, and the 5 O'Clock news headlined Phil had predicted an early spring. I looked out my window, and snow started falling. And, for the next six weeks, we had it almost daily. SMH.
Climate change occurs, but how has mankind thrown the schedule off with the various pollution he creates?
