As a climate scientist, I knew it was time to leave Los Angeles

I am utterly devastated by the Los Angeles wildfires, shaking with rage and grief.

The Altadena community near Pasadena, where the Eaton fire has damaged or destroyed at least 5,000 structures, was my home for 14 years.

I moved my family away two years ago because, as California's climate kept growing drier, hotter and more fiery, I feared that our neighborhood would burn. But even I didn't think fires of this scale and severity would raze it and other large areas of the city this soon.

And yet images of Altadena this week show a hellscape, like a landscape out of Octavia Butler's uncannily prescient climate novel "Parable of the Sower."

One lesson climate change teaches us again and again is that bad things can happen ahead of schedule. Model predictions for climate impacts have tended to be optimistically biased. But now, unfortunately, the heating is accelerating, outpacing scientists' expectations.

We must face the fact that no one is coming to save us, especially in disaster-prone places such as Los Angeles, where the risk of catastrophic wildfire has been clear for years. And so many of us face a real choice - to stay or to leave. I chose to leave.

Often called LA's "best kept secret," Altadena is a quirky hamlet nestled in the foothills, hidden from all the city's traffic snarls, where everyone seemed to know everyone. I arrived with my family in 2008 to start a post-doctorate degree in astrophysics. It felt like we'd landed in paradise: unlimited guacamole from a huge avocado tree in our backyard; flocks of green parrots squawking overhead; Caltech's perfect lawns in Pasadena to lie on with my children, even in January.
