Dissenting Commissioner Troy Paredes notes the potential confusion that could result from having firms speculate on the "physical effects of climate change, such as effects on the severity of weather (for example, floods or hurricanes), sea levels, the arability of farmland, and water availability and quality" and harms to their reputation because of the public perception of data relating to its greenhouse gas emissions.

It would help if coal the cheapest fuel for making electricity were taxed to pay for the climate-changing effects of the carbon dioxide produced when it burns, but even without such a tax, some ambitious entrepreneurs are already talking of alternatives that are cheaper than coal.
ECONOMIST: A fundamental change is coming sooner than you might think
That said, subtler effects of climate change such as more sudden rains and particularly hot days with disproportionate effects on yield are left out, which might mean the study underestimates the effects.
Moreover, because coal ash is now recycled, it reduces the effects on climate change.
