In an interview with VICE founder Shane Smith, President Obama called climate change an example of one of the hardest problems to solve, warning that there eventually comes a point of no return.
“You have to make sure that you get at this thing quick enough and with enough force to be able to make a difference,” Obama said, noting that climate change is an especially difficult problem to tackle because it requires immediate sacrifices for a long term payoff.
In the 18-minute interview, Obama dedicated the first six minutes to climate change, saying that he wanted the country to think of climate change as an immediate and serious problem, a shift in national conscience that could be difficult considering that more than half of Congressional Republicans question or deny the science associated with human-caused climate change, according to research conducted by the CAP Action Fund.
