A nation of fires and assessing your risk

The Climate, Health & Equity Brief is GMMB’s take on the week’s news on the current impacts of climate change. If you haven’t subscribed yet, you can do so by clicking here.

Hot Topic: Burning up. As grim images from space reveal, New Mexico’s Calf Canyon/Hermit’s Peak fire continues to tear through the state. The largest wildfire in the state’s history, Calf Canyon/Hermit’s Peak has eclipsed the size of the city of Los Angeles and is currently the most substantial fire in the United States.  Unfortunately, it is just one of 731 wildfires currently raging across the U.S.—and summer has not yet even begun.

While you may think this is a problem for Western states alone given their arid conditions, think again: An unprecedented new Washington Post analysis shows just how much more pervasive climate-fueled fires are becoming across the entire nation.

The analysis examined factors such as worsening climate conditions, historic weather patterns, fire behavior models and ignition indicators to calculate the wildfire risk faced by every property across the U.S. and found that half of all addresses in the lower 48 states—which house one in six Americans—now face “significant” wildfire risk.

The report revealed that as climate change exacerbates drought and temperature rise nationwide, safe havens are growing increasingly rare. Wildfire risk is increasing even faster than flood risk, with states as far east as Georgia and South Carolina among those with the most homes and buildings threatened by fires.

What’s more, the communities that already bear a disproportionate burden of climate impacts and environmental injustice are now also at greatest danger from wildfires. More than 42% of the U.S. Native American population lives in areas with significant fire probability. The same is true for nearly 25% of the U.S. Hispanic population—and a majority of residents within these communities can’t afford to move, lack wildfire insurance and face job insecurity, which dramatically complicate their ability to recover after a devastating fire.

The analysis concludes with a grim warning: In the next few decades, many people will face even greater danger than they do now, and areas that are traditionally not considered wildfire-prone will soon become so without significant and urgent action to slow the effects of climate change.  To determine the specific wildfire risk in your zip code, be sure to check out the tool in the Kicker below.
