Governor Hogan must personally take a firm, public stand on Maryland's commitment to addressing climate change. Already, Gov. Charlie Baker of Massachusetts and Gov. Phil Scott of Vermont — both, like Governor Hogan, Republicans in largely Democratic states — announced that they will join the U.S. Climate Alliance, a coalition of a dozen states and Puerto Rico -- including Virginia, California and New York -- committed to fulfilling the tenets of the Paris climate agreement. In addition to this inspiring state level commitment, more than 240 U.S. mayors, including D.C. Mayor Muriel E. Bowser, representing more than 56 million Americans from across the country, have committed to upholding the goals enshrined in the Paris agreement. They plan to "intensify efforts to meet each of our cities' current climate goals, push for new action to meet the 1.5 degrees Celsius target, and work together to create a 21st century clean energy economy," according to a statement.
