Wildfires and the Climate Crisis in West America

Worsening Wildfire Problems in Western America

The wildfires in Western America are getting more frequent, intense, and destructive with each passing decade. California, Oregon, and Washington are home to some of the most fierce blazes in history which have ruined entire neighborhoods, ecosystems, and public health services. Strong winds, high temperatures, and dry hurricanes are not the only threat to the region, and along with human-induced climate change, the region is more vulnerable than ever. Fires are aggravated due to extended drought conditions, earlier melting snowpacks, and an uptick in human development across wildland areas. For example, the 2020 fire season is regarded as one of the worst in history, especially for the United States due to the millions of acres and smoke that spread across the country. Exploding fire lines not only endanger people and homes, but severely erode climate conditions due to massive flooding of carbon dioxide emissions. The extreme climate shift results in what was once a rare disaster turning into a yearly catastrophe where the start date keeps getting earlier and longer.

The West is now grappling with the fact that wildfires have transformed from a seasonal problem into an all-year-round peril, fueled by climate change.

Climate Change as a Major Cause of Wildfires

This relation of climate change and wildfires is not merely a theory; it is a scientific fact. Emissions from burning fossil fuels is greenhouse gas and is warming the earth, resulting in extreme heat waves, drought conditions, and irregular patterns of weather. These are setting the groundwork for rapid fire outbreaks. For example, the Western US has experienced a significant increase in the number of “fire weather days”—days dominated by high temperatures, strong winds, and low humidity. This is a problem that is caused by global temperature rise. It is estimated that without significant action being taken to reduce emissions, Western US fire climate models predict the burned wildfire area to increase exponentially by the middle of the century. Escalating temperatures also make weaker ecosystems worse, forest health declines as trees become easier to pest and disease. This results in forests full of dead, desiccated vegetation which is an ideal fire starting material. This change driven by climate overwhelm federal and local resources due to the strain on fire management systems. With increasing seasons and hostile conditions, the cost of suppressing the fires has increased dramatically. Wildfires and climate change are two sides of the same coin which means immediate action is needed to adapt forest management solutions to lower emission levels.

Impacts and the Path Forward

The impacts of more intense wildfires extend well beyond blackened forests and burned lands. Public health, especially, is in danger because of wildfire smoke that can travel for hundreds of miles, endangering millions with harmful particulates that worsen respiratory and cardiovascular diseases. Economically, the destruction is mind-boggling; from the homes and infrastructure that are burnt down, to the agricultural and tourism industries that are thrown off balance. Most vulnerable are low-income and indigenous households that, because of scant resources, tend to get a disproportionate share of these misfortunes. To address this, decision-makers and researchers are proposing deeper climate measures alongside improved land policies. These include investing in controlled burns, thinning out forests, fashioning climate-resilient infrastructure, and setting up early warning systems. Reducing greenhouse gas emissions by shifting to clean energy and sustainable public transport also does a lot in the equation. Private citizens can do their part by pushing for policies that focus on disaster readiness and fortifying their homes and the broader community against fires. While Western America’s wildfires are an indication of a more profound climate crisis, mitigating them needs urgent but strategically thoughtful climate action tackled in the long-term. Only by
