WASHINGTON (AP) Ice photographer and filmmaker James Balog, who says he was watched trillions of tons of ice melt, told the Washington crowd that talking about the science of climate change in the face of the Trump administration and climate change deniers is "a battle between objective reality and ideological fiction."
Pennsylvania State University's Michael Mann got a loud cheer just for his sentence "I am a climate scientist."
Mann, who first created the hockey stick that showed a spike in recent global temperatures after thousands of years said, "there was no more noble pursuit than seeking to insure that policy is informed by the objective assessment of scientific evidence."
Software engineer Bill Wood of Rockville, Maryland, had a plastic protected sign that read "things are so bad even the introverts had to come out."
President Donald Trump said in an Earth Day statement that his administration is "committed to keeping our air and water clean, to preserving our forests, lakes and open spaces and to protecting endangered species."
But that won't be done, he says, in a way that harms "working families" and says the government is "reducing unnecessary burdens on American workers and American companies, while being mindful that our actions must also protect the environment."
