There is no easy fix to address climate change in terms of policy and technology, but there is no question that the current trends of population and energy consumption are unsustainable. We must solve this globally. Pulling out of the Paris Agreement was a critical mistake, This is small comfort, but at least our departure didn't cause the real leaders to walk away from the table. We should not only re-commit to the Paris structure, but also commit to playing a leadership role consistent with our contribution to emissions and that reflects our role as a global leader.
