One scientist doesn’t dispute that global warming is a legitimate claim, nor does he necessarily dispute that man is causing it. According to Professor Emeritus of Earth Sciences and Climate Change at the University of Maine Terry Hughes, “it doesn’t matter” if human activity is causing climate change.
I never doubted it for an instant. The Earth has not always been like this.In fact, Hughes feels that humans likely have a lot to do with the shift in our planet’s climate:
It may have given it a nudge. But there are so many natural events that swamp that out, for example, the eruption of Vesuvius, or Krakatoa. The industrial revolution was more gradual, over decades.
Hughes, however, looks back to the 1970’s when he says his colleagues feared a new ice age. But, as Skeptical Science notes, the “predictions” of an impending icy doom were mostly based in the media’s fear-mongering. The majority of peer-reviewed research at the time actually predicted a warming trend spurred by increasing CO2 in the Earth’s atmosphere.
