2024 natural disasters cost the world $320 billion in damages

While its impact varies from disaster to disaster, extensive research has found that changes in our climate are making extreme weather events like heat waves, hurricanes, flooding and wildfires worse. Now, a new analysis shows us just how costly these natural disasters were in 2024.

Munich Re, a reinsurance company, found that natural disasters in 2024 caused $320 billion worth of financial losses worldwide. That's $52 billion more than in 2023. And of those losses, the company says less than half were covered by insurance.

According to the company, weather catastrophes were responsible for almost all of the financial loss. They say 93% of overall losses and 97% of insured losses were caused by severe weather like floods, wildfires, thunderstorms and tropical cyclones. Hurricanes Helene and Milton took the top spot for the most destructive disasters of 2024.

Munich Re says 2024 was also the third-most expensive year in terms of insured losses and the fifth-most costly for overall costs since 1980.

"The physics are clear: the higher the temperature, the more water vapour and therefore energy is released into the atmosphere. Our planet's weather machine is shifting to a higher gear. Everyone pays the price for worsening weather extremes, but especially the people in countries with little insurance protection or publicly funded support to help with recovery," said Munich Re's chief climate scientist, Tobias Grimm, in a statement.

Climate change amplified dryness, but LA fires still extreme without it: UCLA analysis

In a new quick-turn analysis, UCLA climate scientists found that climate change could be responsible for roughly a quarter of the extreme vegetation dryness present when the Palisades and Eaton fires began. But they say the fires would still have been extreme even without that moisture deficit.

"We believe that the fires would still have been extreme without the climate change components noted above, but would have been somewhat smaller and less intense," the team noted.

The climate scientists at UCLA's Climate & Wildlife Research Initiative considered what contributed to the fire "to quantify how unusual these factors are, in the context of the natural weather and climate variability."

The researchers examined the intense summer heat, drought and extreme precipitation that impacted the region in recent years. They concluded that the unusually warm temperatures during the summer and fall of 2024 are the most likely way climate change could have helped intensify the wildfires by lowering fuel moisture in the region.

However, the analysis found that this stretch of unusually warm weather was likely not the primary driver of the extreme vegetation dryness that was in place at the time of the wildfires.

Researchers point to the lack of early wet season precipitation as the main contributor of the extremely dry fuels, estimating that about 75% of the dryness was due to lack of rain and roughly 25% attributed to the stretch of anomalous warmth. They say the current rain deficit is more likely due to California's highly variable natural climate rather than human-amplified climate change.

"As I've often said, no one claims that climate change directly causes natural disasters. Instead, we highlight that human-caused climate change amplifies these events. As this issue becomes more pronounced, it's essential that we focus on mitigation, adaptation, and planning for the warming that is already inevitable," explained Ginger Zee, ABC News chief meteorologist and chief climate correspondent.

Based on their findings, the research team recommends aggressively suppressing fire ignitions when extreme fire weather is forecast, making homes more fire resistant, and building new units in low wildfire risk zones.

The analysis has not been peer-reviewed and additional findings are likely to emerge as new studies are completed.

A perfect storm: How weather and climate fueled LA's devastating wildfires

The devastating wildfires in Southern California were fueled by a perfect storm of weather and climate factors. While the exact causes of the fires are still under investigation, the conditions that led to their rapid spread are a combination of a lots of rain followed by extreme dryness and powerful winds. We also know that climate change is amplifying the intensity and destructiveness of wildfires in general.

After a period of massive amounts of rain and flooding, Los Angeles has only seen 0.16 inches of rain since May 6, leaving the region exceptionally dry and filled with fuel for potential fires. But dryness alone wasn’t enough to create the chaos. An extraordinary mountain wave wind event, with gusts reaching 100 mph, spread the flames uncontrollably. At that point, firefighters were not going to be able to stop them.

The National Weather Service had warned of these conditions 36 hours before the fires began, calling them “life-threatening and destructive.” Unlike a similar wind event in 2011, this year’s extreme dryness and a unique atmospheric setup made the winds even more devastating, spreading fires to areas not typically impacted by those weather conditions.

While climate change’s exact impact on these fires is still under study, scientists agree that along with rapid urbanization, human-amplified climate change is intensifying dry-wet cycles that increases vegetation growth followed by extreme drying. This hydroclimate whiplash, along with more extreme heat, is contributing to wildfires being larger and more destructive.

How global warming is making Earth's climate more volatile

Scientists know that human-amplified climate change is increasing the frequency and intensity of many extreme weather events, but our changing climate could also be making wild weather swings more common and more extreme, according to new research published in Nature Reviews Earth & Environment and the Fifth National Climate Assessment.

For example, moving from devastating drought to record-breaking precipitation, or vice versa.

Parts of the world, like the southwestern U.S., historically experience highly variable weather and climate conditions, typically shifting from periods of very dry to very wet weather. However, in recent years, the rapid succession of extreme droughts, wildfires and floods has significantly impacted these regions, prompting scientists to look closely at how global warming affects climate variability.

The new research, which involved UCLA and UC Agriculture and Natural Resources, further investigated this variability, focusing specifically on hydroclimate volatility. Hydroclimate volatility is sudden, large and/or frequent transitions between arid and very wet conditions.

Researchers found that this volatility, also known as "hydroclimate whiplash," has become more frequent and will increase significantly as global temperatures rise.

The analysis found that since the mid-20th century, inter-annual hydroclimate volatility has increased by 8% to 31% over land areas, meaning more frequent shifts from dry to wet conditions in recent decades.

"This increase in hydroclimate volatility likely underpins a good portion of the societal perception that the impacts from climate change are accelerating," Daniel Swain, lead researcher and climate scientist with UCLA and UC Agriculture and Natural Resources, said in a statement.

To better illustrate their findings, the authors formally introduced the analogy of an "expanding atmospheric sponge," saying that the underlying physical processes driving the increase in volatility can be compared to using a kitchen sponge.

With each degree of global temperature rise, the hypothetical sponge becomes 7% larger, and, therefore, can hold more water. -- just like a larger kitchen sponge can soak up more water from the countertop compared to a smaller one. And when you wring out the bigger sponge, more water will pour out. A larger sponge will also require more water to become fully saturated.

A warmer atmosphere will also want to soak up more water vapor to achieve this through processes like evaporation, which can enhance dry conditions. These changes in atmospheric water vapor capacity will not only increase the chances of moving from very dry to very wet conditions, but it could fuel droughts and more extreme rainfall.

And as hydroclimate volatility continues to increase, more rapid swings between extreme weather events will amplify many of the associated hazards and potentially require changes to how we manage them.
