Many people out there are still skeptical about the science behind global warming. Heck, you may be one of them. How do climate scientists respond to questions such as, "What about the Bible?"

John Vechey of PopCap Games recently joined The Motley Fool for a climate change summit. His first panel guests were Dr. Rachel Cleetus, a climate economist with the Union of Concerned Scientists, and Dr. Joe Casola, program director for science and impacts at the Center for Climate and Energy Solutions. They address some denialist comments tweeted during the discussions by invoking Christian values, points of economic agreement, and good old-fashioned common sense.

Dr. Casola reminds participants of three key opportunities in addressing climate change:

  1. Energy efficiency: General Electric (NYSE:GE) is one of the pioneers of energy efficiency solutions, with its fingers in nearly all of the new energy pies. The massive conglomerate offers an entire array of products that improve the efficient operation of power plants, airplanes, railroad systems, and wind turbines, just to name a few.
  2. Enhanced oil recovery: BP (NYSE:BP) is pioneering efforts in enhanced oil recovery, a technology that improves the efficiency of a drilling site by extracting the maximum amount of oil from it.
  3. Water efficiency: Intel (NASDAQ:INTC) has an insatiable thirst for pure water in its chip manufacturing processes, so much so that the company started managing municipal water systems to secure its supply in the most efficient manner possible.

Check out the video to hear the scientists' response to climate denialists, as well as their take on opportunities in energy.
