Climate change has been confirmed by scientists to have exacerbated the deadly and devastating wildfires in Los Angeles. Research by the World Weather Attribution revealed that the hot, dry weather that fuelled the inferno was made 35 per cent more likely due to the warming planet. Moreover, the wildfires were 6 per cent more intense as a result of reduced rainfall, which would typically help extinguish blazes during the wildfire season.
The wildfires in Los Angeles began on January 7, spreading rapidly and resulting in approximately 30 fatalities and over 10,000 homes destroyed. Experts from the US, UK, and various European countries, part of the World Weather Attribution network, warned that the extreme hot, dry, and windy conditions that drove the fires were significantly influenced by global warming. Furthermore, they highlighted that if global temperatures increase by 2.6°C above pre-industrial levels, the risk of fire-friendly conditions could rise by another 35 per cent.
The study also revealed that the lower rainfall levels between October and December, typically the period when rain mitigates wildfire risks, are now 2.4 times more likely compared to pre-industrial times. The fires were further propelled by strong “Santa Ana winds,” powerful easterly gusts blowing inland from the coast in the US. Dr Clair Barnes, a researcher at Imperial College London, emphasised that without a swift transition away from fossil fuels, California will continue to face hotter, drier, and more flammable conditions.
Roop Singh from the Red Cross Red Crescent Climate Centre pointed out that while climate change set the stage for the wildfires, other factors like the strong winds and strained water systems exacerbated the situation. The need for better preparedness for increasingly severe wildfires was underscored, urging a transition to renewable energy for a safer future.
The recent wildfires in Los Angeles serve as a stark reminder of the urgent need to address climate change to prevent further devastation. It is crucial for policymakers and individuals alike to take proactive steps towards sustainable practices and renewable energy sources to mitigate the impact of such disasters in the future.
