Wildfire turned sky orange in San Francisco, foretelling future

One year ago today was the most terrifying day of my life.

I’ve faced personal tragedies and professional setbacks, but there are templates to deal with those. You rely on friends and family, you nurse your grief and anger, you seek counseling. With any luck and a lot of hard work, you heal and you move on.

But the day the sky turned orange in San Francisco from widespread wildfire smoke was a different kind of tragedy, precisely because it wasn’t personal — it was communal. It affected all of us. Nobody could help. Everybody was equally freaked out.

We had been breathing wildfire smoke for about three weeks, and all I could think about was how long this new phase, this deep-orange darkness, would last. A day? A week? Three weeks? We were already locked down at home from the Covid pandemic, with the kids out of school and most businesses closed. The added feeling of isolation from this new phase was almost too much to bear.

Those of us who are old enough might remember a brief window in the 1990s when it seemed like the environmental movement was ascendant. Politicians and corporations were paying attention. The entire world banned chlorofluorocarbons in less than a couple years after it became clear they were depleting the ozone layer, exposing us to more solar radiation. The ozone layer is now recovering.

But that moment faded, replaced by the urgency of the War on Terror and the gridlock of hardcore partisan politics, along with a global economic expansion that has lifted hundreds of millions of people out of poverty and into the middle class.

That global economic expansion has been fueled by cheap fossil fuels and accompanied by a dramatic rise in greenhouse gas emissions. This year’s report from the United Nations’ Intergovernmental Panel on Climate Change, released in August, shows the picture very starkly. We are currently averaging 410 parts per million of CO2 in the atmosphere — well above the 382 ppm figure that Al Gore used in his famous chart of CO2 concentrations in the 2006 movie, “An Inconvenient Truth.”

The wildfires in the West aren’t caused entirely by climate change — fires have always been part of the landscape, and forest management practices have definitely played a part. But so did two decades of record heat and a drought that has killed millions of trees. Today’s fires burn hotter and spread faster than any in recent memory, according to scientists and firefighters.

Climate change has been hard for most of us to see and feel. That’s beginning to change. This year’s continuous parade of extreme weather events — floods, hurricanes and wildfires — is a foretelling of what the world faces. If you haven’t faced your orange day yet, chances are you will.

The positive side of all this: More people than ever before are committed to finding solutions. Personally, the orange day in San…
