Global Climate Change Update

Dr. Blaine will be speaking about the history and trends of climate change. He will also be addressing the common questions that surround the subject:

  • “Hasn’t Earth been much warmer than it is now for most of its history? If that is true (and it is), then why worry about a few degrees warming in the next 50-100 years?”
  • “Isn’t it likely that the warming is natural and not caused by humans at all?”
  • “Hasn’t global temperatures always fluctuated? After all, the glacial grooves at Kelley’s Island prove that Ohio was once covered with ice. Something caused that global cooling, and when the ice age ended, something caused massive global warming – and none of it was humans. So why the concern about global warming now?”
