The Caldor Fire started August 14, 2021 from unknown causes. Sources reveal that the fire has impacted two major counties, El Dorado and Amador, burning more than 200,000 acres (or just over 300 miles) of land over duration of 21 days that its been active. The spreading fire has reached the Tahoe Basin, prompting officials to call for mandatory evacuations.

Lake Tahoe, which lies on California’s border near Nevada, is a freshwater lake which is a renown tourist destination due to its outdoor recreational activities such as hiking, skiing and cruises. 20,000 or more residents of south Lake Tahoe have had to be evacuated as commercial structures and hundreds of homes have succumb to the growing blaze. Because the communities of California’s and Nevada’s mountain ranges depend heavily on tourism, one has to wander how badly their economy have been afflicted Firefighters have been using helicopters to pour hundreds of thousands of gallons of water and fire retardant on the flames hoping to salvage mountainous forestry and infrastructure. Firefighters that were already working to manage the still burning Dixie Fire had to be called in to combat the Caldor Fire and stop it from further spreading. Are fire fighters and their equipment being spread too thinly?

Climate Change and Wildfires

For years, researchers from the International Panel on Climate Change (IPCC) have warned that climate change would add to the severity and frequency of wildfires. Though wildfires are a naturally occurring, they are worsened by certain preexisting conditions. Digging up and burning fossil fuels produces greenhouse gases, increasing Earth’s capacity to retain incoming solar heat. As the planet slowly warms, the soils of certain regions dry sooner, causing said soil and its vegetation to be susceptible to drying out. Dried vegetation acts as kindling for flames. Further, snow melts at accelerated rates, decreasing the availability of water; thereby making the likelihood of fire more probable. Hot and hot conditions are highly conducive to wildfires because they make plants more flammable by evaporating the moisture within them. The Environmental Protection Agency (EPA) reports that the annual area burned by has been increasing since the 1980s. According to the National Geographic for Environmental Information, the 1980s also mark the beginning of a temperature rise of 0.2 Celsius (0.3 degrees Fahrenheit each subsequent decade.

The frequency of Californian fires are happening at an unprecedented rate, leaving me to wonder how prepared the state really is for the dangerous conditions its facing.
