Can we reach 100 percent renewable energy in time to avert climate catastrophe?

In this article in August 2019 Chris Smith, SMURPHS researcher discussed his opinions on how to prevent the worst climate scenarios, carbon emissions must be slashed to net-zero by 2050

“I think this transition [to renewables] will happen,” said Chris Smith, a research fellow in physical climate change at the University of Leeds, England. “The question is, will it happen fast enough? Personally, I think not. I don’t think we’re headed for 4 degrees [Celsius] of warming, but I’d be very surprised if we managed to limit it to one and a half.”
