Rising Wildfire Threat in Northern Ireland
Northern Ireland is experiencing an increasing risk of wildfires as environmental conditions become more conducive to their occurrence, according to a recent report by researchers at Imperial College London.
The study identifies spring as the period undergoing the most significant change. Traditionally the peak wildfire season, spring is now witnessing more frequent droughts and conditions favorable to fire ignition and spread.
Data indicates a rise in spring drought events alongside a sharp increase in "fire weather"—a combination of warmth, dryness, and wind that facilitates rapid fire outbreaks.
Experts caution that this combination, compounded by climate change, is extending and intensifying the wildfire season.
Spring has historically been the season with the highest wildfire risk due to dry vegetation such as grass and heather that ignite easily.
The report emphasizes that climate change is exacerbating these conditions.
"This analysis shows that climate change is having a clear, exacerbating effect on wildfire danger in the UK," Theodore Keeping, research associate in the analysis of extreme weather and wildfires at Imperial College London, stated.
"We are seeing an increased likelihood of severe spring drought in many parts of the UK due to greater warming.
Whilst human-cause climate change continues, this shift towards more fire-prone conditions is expected to continue."
Warmer temperatures are causing vegetation to dry out earlier in the year, while the atmosphere's increased capacity to draw moisture from the ground results in landscapes remaining flammable for longer periods.
Climate Change and Recent Wildfire Events
The findings come in the wake of recent wildfires in Northern Ireland during April, which required the deployment of hundreds of firefighters to contain the blazes.
Earlier in April, the Department of Agriculture, Environment, and Rural Affairs (Daera) introduced an action plan aimed at mitigating wildfire risks.
Although spring remains the primary concern, the report also highlights a growing wildfire risk during summer months.
Historically, summer wildfires in Northern Ireland have been relatively rare; however, data now shows an increase in periods of severe fire weather, indicating the potential for a lengthened fire season in the future.
According to the Met Office, the extreme fires experienced during the UK's 2022 heatwave were made at least six times more likely due to human-induced climate change.
The 2022 summer saw temperatures surpass 40°C for the first time in some parts of Britain, placing significant strain on fire services and demonstrating how rising heat and dryness can rapidly escalate fire risks.
Researchers note that similar mechanisms are now influencing spring conditions, even in the absence of record-breaking temperatures.
