Brown said there should be urgency to deal with climate change. "I think this almost has to be at the level of a crusade," he said.
This week, Brown announced a $1 billion emergency package to deal with the state's drought, which is entering its fourth year. "We are running out of time because it's not raining," he said. "This is a serious matter we're experiencing in California, as kind of a foretaste. But there is no doubt that into the future, we're going to have more problems." He also said research results show a "connection" between California's drought and climate change.
When asked by host Chuck Todd whether he would run for president if he was 10 years younger, Brown said he would.
