My view is I am seeing more extreme events. So there is chance those extreme events could be caused by climate change. Example Miami spending $Billions to keep dry as sea levels rise.

So there is a chance reduced CO2 by investing renewable energy could mitigate more extreme weather and sea rise. What is the cost? The investment lowers the cost of electric power production. In other words it has a positive return on investment.

So based on engineering data it does not matter which scientist is right because the cost of wind solar and grid storage are less than fossil fuel. It might lower the. Cost of extreme weather and rising sea levels, so that’s a bonus.
The cost of renewable energy is dropping every year and will continue to drop. The capital markets know there is a $10 trillion market that can be won or taken from oil and natural gas industries and that shift will continue.
