This summer the world is experiencing the implications of climate change--heat waves, floods, fires. RGGI alone will not solve climate change, but it is part of a solution to a collective action problem. The costs of environmental harm to our economy and our children's health far outweigh those of RGGI. I appreciate the opportunity to comment, and I hope we can elevate this health / quality-of-life issue above politics and focus on the well-being of Virginians (current and future).
