“It's a terrible, terrible tragedy for everybody concerned. It's terrible news for health, for air quality, and obviously for people's lives, ecosystems and the local economy.”

5. SOUNDBITE (English) Clare Nullis, Spokesperson, World Meteorological Organization (WMO):
“The big compounding factor in this is the winds. It's a well-known weather pattern in California, it's quite local, called the ‘Santa Ana winds’, and they typically occur in this region. The high winds from the mountains, they cause temperatures to rise, and they cause very low humidity, drying out the ground and vegetation.”

7. SOUNDBITE (English) Clare Nullis, Spokesperson, World Meteorological Organization (WMO):
“To quote NOAA (the US National Oceanic and Atmospheric Administration): ‘climate change, including increased heat, extended drought and a thirsty atmosphere have been a key driver in increasing the heat and extent of wildfires in the western United States during the last two decades.”

“It does highlight the importance of early warnings. The warnings have, in this instance, been very, very good. You know, people have been evacuated. It’s been impossible to save houses. But, you know, loss of lives is still too high, but it has been kept to a relative minimum.”

11. SOUNDBITE (English) Dr. Margaret Harris, Spokesperson, World Health Organization (WHO):
“It can be full of PM 2.5, which is a very small particulate matter (PM or particle pollution) that can get right down into the lungs. It is associated with premature death in the general population and can cause and exacerbate diseases of lung, heart, brain, nervous system, skin, gut, kidney, eyes, nose and liver. And it's also been shown to lead to cognitive impairment, so damage your intellectual capacity and to memory loss.”

“The World Meteorological Organization will later today confirm that 2024 was the hottest year on record. We saw extraordinary land and sea surface temperatures, extraordinary ocean heat, accompanied by, as we all know, very extreme weather affecting many countries around the world, destroying lives, livelihoods, hopes and dreams.”

The powerful dry winds and tinderbox conditions that have been fueling the continuing Los Angeles wildfire tragedy have been made worse by climate change, the World Meteorological Organization (WMO) said today (10 Jan).
At least 10 people have been reported killed and more than 10,000 buildings have burned to the ground since the Californian fires broke out and spread, propelled by a well-known weather pattern called the Santa Ana Winds - “high winds from the mountains that cause temperatures to rise and very low humidity, drying out the ground and vegetation,” WMO said.
Adding to the potential for disaster, the UN weather agency also pointed out that although last year's rainy season for the Los Angeles area was reportedly above normal, “from late 2024 until now, it has been below normal”, which explains why vegetation is so dry.
“It's a terrible tragedy for everybody concerned”, said Clare Nullis, WMO spokesperson, speaking to journalists in Geneva.
“It's terrible news for health, for air quality and obviously for people's lives, ecosystems and the local economy”.
Fires remain uncontrolled in many areas as exhausted firefighters continued to tackle countless blazes, whose original cause has not been confirmed.
The National Weather Service in Los Angeles issued a Red Flag warning in effect through Friday morning local time across Southern California, as officials warned that more high winds could fan the flames.
Although wildfires are part of the natural ecosystem in the US west coast as elsewhere, their intensity and frequency have been increasing at an alarming rate in recent decades.
WMO said that climate change has exacerbated such disasters, making rainfall heavier in tropical areas and increasing heatwaves.
Destructive wildfires require the alignment of several factors, including temperature, humidity and the lack of moisture in trees, shrubs, grass and forest undergrowth.
All these factors have strong direct or indirect ties to climate variability and climate change, explained Nullis. “Climate change, including increased heat, extended drought and a thirsty atmosphere have been a key driver in increasing the heat and extent of wildfires in the western United States during the last two decades,” she added, citing the US National Oceanic and Atmospheric Administration (NOAA).
Hundreds of thousands of people had to leave their homes or have remained under evacuation warnings since the fires broke out last Tuesday. Early warnings are key to avoiding dramatic loss of life; WMO said.
“It’s been impossible to save houses,” deplored Nullis, adding that although the number of victims has been “too high, it has been kept to a relative minimum”.
Early warnings to evacuate are also vital to avoid life-threatening smoke inhalation. Wildfires that burn near populated areas can have a significant impact on human mortality and morbidity depending on the size, speed and proximity to the fire, UN World Health Organization spokesperson, Dr Margaret Harris, explained.
Wildfire smoke is a mixture of air pollutants of which particulate matter (PM) is the principal public health threat, she continued.
PM2.5 from wildfire smoke is associated with premature deaths in the general population as it can penetrate deep into the lungs, Dr Harris continued.
“It can cause and exacerbate diseases of lung, heart, brain, nervous system, skin, gut, kidney, eyes, nose and liver… And it's also been shown to lead to cognitive impairment, damage your intellectual capacity and cause memory loss.” Firefighters and emergency response workers are at particular risk, she added.
As wildfires in California continue to rage, the UN weather agency confirmed 2024 was the hottest year on record, ahead of the release of a comprehensive report combining the findings of several regional climate and meteorological monitoring institutes in the UK, China, the EU and the US.
“We saw extraordinary land and sea surface temperatures, extraordinary ocean heat, accompanied by, as we all know, very extreme weather affecting many countries around the world, destroying lives, livelihoods, hopes and dreams,” Nullis said.
