Explained: The Relationship Between Climate Change and Wildfires
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.

Tracking Antarctica Sea Ice Loss in 2023
Antarctica’s ice extent has reached record lows. This visual details and maps Antarctica sea ice loss over the last two years.

Tracking Antarctica Sea Ice Loss in 2023
Scientists have been tracking the extent and concentrations of Antarctica’s sea ice for decades, and the last two years have raised global alarm bells.
As temperatures are breaking records around the world, the southernmost continent’s ice sheet is visibly smaller than it has been in decades past.
The above graphic uses tracking data from the National Oceanic and Atmospheric Administration (NOAA) and the National Snow and Ice Data Center (NSIDC) to visualize sea ice extent in Antarctica as of August 2023
How Much Ice Has Antarctica Lost?
According to satellite data tracked by the NSIDC, sea ice extent in Antarctica has shrunk to record lows.
When compared to previously charted data dating back to 1979, daily record lows in sea ice extent have been recorded for every day in 2023 so far.
Here is how daily Antarctic sea ice extent in 2023 compares to 2022 (which had many of the previous record lows), and the median from 1981 to 2010.

Antarctica’s sea ice extent on August 24, 2023 was 1.42 million square kilometers smaller than the year before. When compared to the median extent for that date from 1980 to 2010, it was 2.07 million square kilometers smaller.
Keep in mind that July and August are the coldest months in Antarctica. Its position on the South Pole gives it a very long winter ranging from the end of February to the end of September, with ice building up before melting temperatures arrive in October.
Antarctica Sea Ice and the Rest of the World
Even though the continent is thousands of kilometers from most of Earth’s land and populace, its ice has an important impact on the rest of the planet.
Antarctica’s large ice sheet is able to reflect a lot of sunlight in sunnier months, reducing the amount absorbed by the ocean. The wider its extent builds up over the winter, the more sunlight and heat it is able to reflect.
It’s also important to consider that this ice comes from a regular pattern of freezing and melting ocean water. The more ice is lost to the oceans compared to what accumulates in a given year, the higher sea levels rise around the world.
