How Climate Change is Influencing Wildfires

Each year, thousands of wildfires burn through millions of acres of land around the world.

We’ve already seen the mass devastation that wildfires can bring, especially in places like Australia, Serbia, and California. But new research by the UN indicates that things might get even worse by the end of the century. By 2100, the frequency of wildfires could increase by up to 50%.

What’s causing this influx of wildfires around the world? Below, we dig into how climate change is impacting wildfires—and how in turn, wildfires are impacting climate change.

Climate Conditions That Support Wildfires

Before diving in, it’s worth going over the basics of wildfires, and how they get started in the first place. An area’s vulnerability to wildfires, also known as its fire regime, depends on three major conditions: its atmosphere, vegetation, and ignitions.

① Atmosphere

Atmosphere plays a big part in how sensitive an area is to wildfires. For instance, wind can increase oxygen supply in an area, which would help fuel a wildfire, and may even transfer embers to new locations.

② Vegetation

Vegetation is also a huge factor in whether or not an area is vulnerable to wildfires. A region with drier vegetation may catch fire more easily, and an area with more forest or shrubs provides more fuel for potential blazes.

③ Ignitions

An area that’s close to volcanic activity, or prone to lightning storms may be more susceptible to wildfires. However, human activity like campfires or faulty equipment can also trigger fires, so popular areas for camping or logging may be at higher risk as well.

While these conditions vary depending on the location, in general, fire regimes are being impacted by climate change, which is causing an influx in the duration and intensity of wildfires around the world.

The Fire Climate Feedback Loop

Since the 1850s, global surface temperatures have risen by about 1.0°C (1.8°F).

These increased surface temperatures have had far-reaching impacts on our climate—in the Northern Hemisphere, warmer temperatures have led to less snow, earlier arrival of spring, and ultimately longer, drier fire seasons.

These longer fire seasons have led to an influx of wildfires. But here’s the kicker—wildfires emit tons of carbon. In 2021, wildfires around the world emitted an estimated 1.76 billion tonnes of carbon into the atmosphere, which for context, is more than double the annual emissions from the entire country of Germany.

This carbon gets trapped in our atmosphere and contributes to rising surface temperatures. In other words, more carbon creates more wildfires—and more wildfires create more carbon.

Extreme Weather Events Are Rising In General

It’s not just wildfires that are growing in frequency and intensity because of climate change—droughts, heatwaves, and floods are also becoming more common around the world.

This year, temperatures reached all-time highs across Europe, which wrecked havoc across the continent, impacted infrastructure, and even took lives.

Experts warn that this may become the new normal. To help mitigate risk, governments, policymakers, and companies need to band together to create safeguards and establish proper preventative measures.

Ranked: Top 20 Countries by Plastic Waste per Capita

Visualizing plastic waste per capita reveals a surprising list of countries that you may not have expected.

Ranked: Top 20 Countries by Plastic Waste per Capita

This was originally posted on our Voronoi app. Download the app for free on iOS or Android and discover incredible data-driven charts from a variety of trusted sources.

Single-use plastic waste is perhaps one of the biggest environmental issues of our time. Every year, millions of tons of plastic end up in oceans and landfills, harming wildlife and ecosystems.

To make matters worse, plastics take hundreds of years to decompose, leading to long-term environmental and health hazards as they break down into microplastics that contaminate water and food sources.

In this graphic, we visualized the top 20 countries that generated the most single-use plastic waste per capita in 2019, measured in kilograms per person. Figures come from research published in May 2021, which we sourced from Statista.

Data and Key Takeaways

The data we used to create this graphic is listed in the table below.

Countries from all around the world are present in this ranking, highlighting how plastic waste isn’t concentrated in any one region.

It’s also interesting to note how most of the countries in this top 20 ranking are wealthier, more developed nations. These nations have higher levels of consumption, with greater access to packaged goods, take-out services, and disposable products, all of which rely on single-use plastics.

Where’s China and India?

Note that we’ve visualized plastic waste per capita, which is different from the total amount of waste produced by a country. It is for this reason that major polluters, such as China and India, are not present in this ranking.

It’s also worth noting that this focuses on the demand side of plastics, rather than where plastic products were initially created or produced.
