Climate change is burning down California

Climate change was long regarded as a distant threat, one happening in far off places and future times. That is unfortunately no longer the case. Climate change is here, and it’s burning through California.

I spent five years in the San Francisco Bay Area getting my undergraduate degrees in applied math and physics from UC-Berkeley. To see my campus threatened by the fires is heartbreaking. I can’t even imagine how bad it is for those who have spent their entire lives, not just a beloved portion of it, in the East Bay. My thoughts are with those struggling to survive this fire, and are choking through the clouds of smoke it casts across the state.

Tragically, climate change will only bring more of these disasters to our doorsteps, demanding our attention by putting more and more lives in direct danger.

When it comes to climate change and wildfire, there is a solid connection.

Once a fire ignites, the conditions fostered by climate change increase the size, frequency, and intensity of wildfires, and lengthen the fire season. A slew of studies have identified these climate change signals in recent western wildfire trends. Climate change has led to an average temperature increase of 2°F in the western U.S., and this is making fires worse by heating up and drying out the landscape. When the ground is parched and plants are dry, it’s far easier for fire to spread further, and faster.

In the Western US, climate change has increased the risk of fire weather fivefold and has doubled how much land has burned. Wildfire frequency has quadrupled since the 1980s, and fire season has lengthened by more than two months (78 days). These changes are largely linked to warmer temperatures and earlier snowmelt. Both ingredients (warmer temperatures and earlier snowmelt) have in turn been directly attributed to climate change. [Continue reading…]

Right now, wildfires are scorching tens of thousands of acres in California, choking the air with smoke, spurring widespread prophylactic blackouts, and forcing the evacuation of hundreds of thousands of people. Right now, roughly 130,000 Californians are homeless, and millions more are shelling out far more in rent than they can afford, commuting into expensive cities from faraway suburbs and towns, or doubling up in houses and apartments.

Wildfires and lack of affordable housing—these are two of the most visible and urgent crises facing California, raising the question of whether the country’s dreamiest, most optimistic state is fast becoming unlivable. Climate change is turning it into a tinderbox; the soaring cost of living is forcing even wealthy families into financial precarity. And, in some ways, the two crises are one: The housing crunch in urban centers has pushed construction to cheaper, more peripheral areas, where wildfire risk is greater. [Continue reading…]
