CRAZY as it may sound, this is the perfect time to enact a sensible policy to address the dangerous threat of climate change. Before you call us nuts, hear us out.

During his eight years in office, President Obama regularly warned of the very real dangers of global warming, but he did not sign any meaningful domestic legislation to address the problem, largely because he and Congress did not see eye to eye. Instead, Mr. Obama left us with a grab bag of regulations aimed at reducing carbon emissions, often established by executive order.

In comes President Trump, who seems much less concerned about the risks of climate change, and more worried about how excessive regulation impedes economic growth and depresses living standards. As Democrats are learning the hard way, it is all too easy for a new administration to reverse the executive orders of its predecessors.

On-again-off-again regulation is a poor way to protect the environment. And by creating needless uncertainty for businesses that are planning long-term capital investments, it is also a poor way to promote robust economic growth.
