California wildfires now larger than New York City and Boston combined

One week after the Thomas Fire exploded from a brush fire to a raging inferno, hundreds of firefighters are still struggling to contain it.

The blaze is larger than all of New York City and was only 15% contained as of Monday morning, according to the fire protection agency CAL FIRE.

At more than 230,000 acres in Ventura and Santa Barbara counties, the Thomas Fire is now the fifth largest wildfire in modern California history. But it's only one of six major wildfires torching the state.

As the flames move on to new neighborhoods, some evacuated residents have returned to find no home standing.

David Karian used a hand rake to sift through the charred rubble of his elderly parents' home in Ventura.

"There's not much, but if there's a few things that will help them have some connection to the past, then that what I'm trying to do," he said. "That's what it is ... memories of a lot of years."

New normal?

As California Gov. Jerry Brown surveyed the damage in Ventura County, he predicted that extreme fire activity would happen on a regular basis for decades.

"With climate change, some scientists are saying that Southern California is literally burning up," the governor, who supports climate science, said Saturday. "So we have to have the resources to combat the fires, and we also have to invest in managing the vegetation and forests ... in a place that's getting hotter."

As for those facing the flames of the current wildfires, there's gratitude -- for life, community and the efforts of the firefighters working to protect both.

One family whose home was destroyed in the Creek Fire said they had lost everything to the blaze but were grateful to be alive.

"For me, it was like my 15 years of living here was flashing by -- of memories, you know, the gatherings, all that," Javier Hernandez told CNN affiliate KCAL/KCBS. "And then at the same time, we were like, 'OK, my family's OK. If it's gonna burn, it's gonna burn.'"
