(CNN)Scientist and astrophysicist Neil deGrasse Tyson said Sunday that, in the wake of devastating floods and damage caused by Hurricanes Harvey and Irma, climate change had become so severe that the country "might not be able to recover." In an interview on CNN's "GPS," Tyson got emotional when Fareed Zakaria asked what he made of Homeland Security Adviser Tom Bossert's refusal to say whether climate change had been a factor in Hurricanes Harvey or Irma's strength — despite scientific evidence pointing to the fact that it had made the storms more destructive. "Fifty inches of rain in Houston!" Tyson exclaimed, adding, "This is a shot across our bow, a hurricane the width of Florida going up the center of Florida!""What will it take for people to recognize that a community of scientists are learning objective truths about the natural world and that you can benefit from knowing about it?" he said.Tyson told Zakaria that he had no patience for those who, as he put it, "cherry pick" scientific studies according to their belief system.Read More"The press will sometimes find a single paper, and say, 'Oh here's a new truth, if this study holds it.' But an emergent scientific truth, for it to become an objective truth, a truth that is true whether or not you believe in it, it requires more than one scientific paper," he said."It requires a whole system of people's research all leaning in the same direction, all pointing to the same consequences," he added. "That's what we have with climate change, as induced by human conduct."Tyson said he was gravely concerned that by engaging in debates over the existence of climate change, as opposed to discussions on how best to tackle it, the country was wasting valuable time and resources. "The day two politicians are arguing about whether science is true, it means nothing gets done. Nothing," he said. "It's the beginning of the end of an informed democracy, as I've said many times. What I'd rather happen is you recognize what is scientifically truth, then you have your political debate." Tyson told Zakaria that he believed that the longer the delay when it comes to responding to the ongoing threat of climate change, the bleaker the outcome. And perhaps, he hazarded, it was already even too late."I worry that we might not be able to recover from this because all our greatest cities are on the oceans and water's edges, historically for commerce and transportation," he said."And as storms kick in, as water levels rise, they are the first to go," he said. "And we don't have a system — we don't have a civilization with the capacity to pick up a city and move it inland 20 miles. That's — this is happening faster than our ability to respond. That could have huge economic consequences."
