Rochster Business Journal: Can the left and right talk about climate change without guilt?
"I speculate that the assignment of responsibility contributes to the left/right conflict. Opponents of climate policy remind us that global warming and cooling occurred in the past, well before humans had the capacity to affect the atmosphere. Climate activists, by contrast, rarely fail to include the phrase “caused by human activity” in the discussion. Does it really matter? As long as we accept that greenhouse gases matter and that the problem poses significant risk, then the policy solutions are pretty much the same whether the cause is natural or anthropogenic."
