Forest fires are shifting north and intensifying – here’s what that means for the planet

Increasing fires are a symptom of climate change

Limiting the burning of fossil fuels is central to minimising future fire risk. Without drastic cuts to greenhouse gas emissions, more severe and widespread forest fires are likely, with increasing damage to ecosystems, biodiversity and the climate.

Our study also highlighted the importance of updating international reporting standards on carbon emissions. As forest fires become more closely linked to human-driven climate change, it’s crucial that fire emissions be included in national carbon budgets to provide a more accurate picture of the planet’s carbon fluxes.

There is also a risk of overestimating how much carbon is stored by reforesting areas, especially outside the tropics. Many carbon offset schemes rely on planting new trees or delaying the harvest of existing ones to absorb CO₂, but if the growing threat of forest fires isn’t properly accounted for, these projects could fail to deliver the carbon savings they promise.

Forest fires are no longer just a natural occurrence. As they shift north and intensify, these fires are a clear symptom of human-caused climate change.

It’s essential to recognise the growing role that fires play in the carbon cycle. By doing so, we can better manage fire risks, safeguard forests and ensure a more resilient future for the planet.
