1. Anthropogenic Climate Change Increases Wildfire Risk
A. Rising Temperatures Increase Fuel Aridity
Human-caused greenhouse gas emissions—documented by the Intergovernmental Panel on Climate Change—have increased global mean temperatures by ~1.1–1.3°C above pre-industrial levels.
Higher temperatures:
Increase evapotranspiration
Dry out soils and vegetation
Lengthen fire seasons
Increase vapor pressure deficit (VPD)
Warmer air holds more moisture, pulling water from plants and soils, producing drier fuels that ignite more easily and burn more intensely.
Empirical studies in the western United States show that anthropogenic warming has:
More than doubled the cumulative forest fire area since the 1980s
Significantly increased large-fire probability
B. Earlier Snowmelt and Prolonged Drought
In western North America:
Earlier snowpack melt extends dry seasons
Reduced snowpack decreases summer soil moisture
Multi-year droughts become more severe under warming
Climate models assessed in IPCC AR6 attribute increased fire weather in many regions directly to anthropogenic warming.
C. Increased Frequency of Extreme Fire Weather
Climate change increases:
Heat waves
Lightning activity (in some regions)
Compound dry/windy events
Extreme fire weather indices (e.g., Fire Weather Index) show statistically significant upward trends globally.
Regions with especially strong documented correlations include:
Western U.S.
Australia
Mediterranean Basin
Siberia
2. Observed Increases in Fire Frequency and Severity
Examples:
2020 California wildfire season: record-breaking acreage burned and extreme fire behavior
2019–2020 Australian bushfire season: unprecedented intensity and ecological impact
Increasing boreal fires in Siberia and Canada
Across multiple continents, fire seasons are:
Longer
More intense
Producing more megafires (>100,000 acres)
3. The Positive Feedback Loop
Wildfires worsen climate change through several mechanisms.
A. Carbon Release
Forests store vast carbon stocks. When they burn:
CO₂ is released rapidly
Methane (CH₄) and nitrous oxide (N₂O) are emitted
Black carbon (soot) is produced
Large wildfire seasons can emit hundreds of millions of tons of CO₂, sometimes rivaling national fossil fuel emissions.
This converts forests from:
Carbon sinks → Carbon sources
B. Loss of Future Carbon Sequestration
After severe fires:
Tree mortality reduces future carbon uptake
Regeneration may be slow or incomplete
Some ecosystems convert from forest → shrubland/grassland
This long-term vegetation shift reduces carbon storage capacity.
C. Albedo and Cryosphere Effects
Black carbon from fires:
Deposits on Arctic snow and ice
Reduces albedo (reflectivity)
Accelerates melting
This amplifies warming—another positive feedback.
D. Permafrost Feedback (Boreal Fires)
In Arctic and boreal regions:
Fires remove insulating vegetation
Expose permafrost
Increase thaw depth
Release stored methane and CO₂
This links wildfire activity directly to long-term carbon cycle destabilization.
4. The Feedback Loop Structure
The cycle can be conceptualized as:
Anthropogenic greenhouse gas emissions ↑
Global temperatures ↑
Drought and fire weather ↑
Wildfire frequency/severity ↑
Carbon emissions from fires ↑
Carbon sinks reduced
Atmospheric greenhouse gases ↑
Further warming
This is a self-reinforcing (positive) feedback loop.
5. Strength of the Correlation
The evidence base includes:
Detection and attribution studies
Climate model simulations with and without anthropogenic forcing
Statistical correlations between VPD and burned area
Longitudinal observational datasets
The Intergovernmental Panel on Climate Change concludes with high confidence that climate change has increased fire weather in many regions and will continue to do so.
While ignition sources (human activity, lightning) and land management practices matter, the climate signal is now clearly detectable in many ecosystems.
6. Important Nuance
To present this rigorously:
Climate change does not cause every individual fire.
Land management, fuel accumulation, and ignition sources are critical mediators.
The relationship is strongest in temperature-limited forests.
Some regions show complex or mixed trends.
But the statistical trend toward more extreme fire weather under anthropogenic warming is robust.
Conclusion
There is substantial empirical and mechanistic evidence that:
Anthropogenic climate change increases the probability, size, and severity of wildfires.
Wildfires release greenhouse gases and reduce carbon sinks.
These effects create reinforcing feedback loops that amplify climate change.
This is not merely theoretical; it is observable in current climate and fire records across multiple continents.

There is no direct correlation between climate change, which is changing continuously, and wild fires. There is weather. Droughts happen, wild fires happen. Wildfires are more severe because of forestry practices that prevent the undergrowth from being burned out periodically. The undergrowth builds up creating more fuel for expected fires. In that way there is a man made cause but the frequency is up to nature.
