Still, others see positive changes on the horizon.
"Twenty years ago, climate change wasn't seen as an issue at all, but since then, technology has improved rapidly," Griggs said. "We don't have to hang around and wait for something bad to happen. There's no question that we can deal with all of these climate change issues now, if we want to. The real issue is: Will we? Will there be the political will and the leadership to take on these things?"
As for whether he remains optimistic overall, Griggs is a little more hesitant. "I'm schizophrenic about it," he said. " times, I look at what's happening in the world and the lack of progress, and I say, we're stuffed. On my good days, I'm optimistic and I see us moving in a direction that will allow us to solve these problems."
