As wildfires sweep across the West Coast, it becomes increasingly vital that we understand the cause of these disasters that can leave people homeless, injured, or even dead. As climate change causes temperatures to rise in the hot, arid climate of California, wildfires are becoming increasingly more likely to occur.
Anthropogenic climate change (ACC) is climate change caused by humans. According to multiple studies, ACC is largely responsible for dramatic increases in aridity in the past 30 years. Dry foliage serves as fuel for these fires, but once they’ve gained momentum, they can burn towns or even cities. In the past, fires tended to occur within a period of a few months each year, but that time period has also increased.
A new approach to wildfire prevention, called fire modeling, may be able to identify areas where controlled burns could reduce wildfire danger. Park Williams, a bioclimatologist at Columbia’s Lamont-Doherty Earth Observatory, said that “there are many methods [of fire modeling] emerging from many groups.” During a meeting in October, Williams introduced the new science to an audience that consisted of fire modelers, scientists, public land managers, insurance representatives, and many more who are dedicated to preventing the spread of wildfires.
The meeting brought a lot of hope for the regulation of these damaging fires, said Williams. “The discussions exposed a lot of opportunities for fire modeling to be used for pro-active land-management measures.” In time, fire modeling and other innovations will hopefully present new solutions in counteracting these massive wildfires that destroy communities around the world.
*Ellen Jorgensen and Grace James are juniors at the Grace Church School in Manhattan. In Fall 2017, they were part of a Science Communication Class created by Columbia’s Lamont-Doherty Earth Observatory. The class pulled in speakers from Lamont-Doherty and the Earth Institute to introduce students to “real world” communications issues. Students learned about how to communicate science via written work and videos, how to form opinions and debate a science topic, and how to talk about science policy. This blog post was written as a culminating activity in the class.
In recent years you may have noticed the increase in wildfires and their severity in Colorado and the entire western region of the United States for that matter. According to KDVR.com (2018), firefighting costs are expected to exceed $200 million in 2018. While many will argue the cause and possible solutions for the fires, it is hard for anyone to deny the fact that the fires are increasing. As DW.com (n.d.) explains, 2015 was a record breaking year for forest fires with the overall square acreage burned topping 10 million nationwide. There are many proposed solutions to dealing with wildfire. Among the top proposed solutions are forest thinning and controlled burns. Opposition to both actions will argue that they cause more harm than good, while research shows that preventative measures do actually work. With so many fires ravaging beautiful parts of our state and country we must raise our level of concern and seek solutions to slow and eventually end wild fires.
