The argument swirls around which side is right, the climate deniers or the climate scientists. I suggest that we instead use a different approach: the consequences one side or the other being wrong.
If the believers get their way but are wrong, we will have spent multiple billions of dollars on non-polluting renewable energy sources at the cost of huge financial burdens on current energy suppliers. But we will have a higher quality of air and water and thus will our overall quality of life benefit. Oil imports will plummet reducing or eliminating the influence of mid east oil on our economy and foreign policies.
On the other hand, if the deniers prevail but are wrong, we will have saved billions of dollars, but rising waters will devastate shorelines throughout the world, temperature extremes and severe weather will continue to increase, ocean temperatures will rise, marine and animal life will be significantly affected with major extinctions likely. Agriculture will be severely altered increasing the likelihood of mass starvations worldwide.
Perhaps this simple thought exercise might help some to decide which is the better choice.
