The following is personnel opinion. Climate change is NOT exclusively man made! Michigan was covered by a glacier only several thousand years ago and it’s demise was not man made, anymore than man is exclusively causing climate change today. One volcano puts more CO2 into the atmosphere, negating any effort man is contributing to CO2 reduction. Man made CO2 causing any present climate change is purely wishful thinking. Follow the money for research grants of taxpayer money to supposedly prove climate change is a man made cause, and that the cure is shutting down all oil exploration and distribution, not building power plants, etc. “Experts” are masters in intimidation. Building the tunnel is by far the best solution to the problem.
