Changing minds about climate change policy can be done -- sometimes

Researchers found that open-minded people became more supportive of government intervention after viewing videos presenting both sides of the issue. Closed-minded individuals did not change their views, regardless of the messages they received. The study suggests climate change denialists may be less effective in swaying public opinion.

Restricting nuclear power has little effect on the cost of climate policies

A recent study by Potsdam Institute for Climate Impact Research found that restricting nuclear power has minimal effect on the cost of climate policies. The researchers discovered that early retirement of nuclear power plants would lead to cumulative global GDP losses amounting to around 10-20 percent of climate policy costs.
