Costliest Climate Disasters in US History: 2025's Devastating Start (2026)

The first half of 2025 shattered records, becoming the costliest period ever for climate disasters in the United States. This devastating reality, driven by catastrophic wildfires and relentless storms, paints a stark picture of our changing climate. Let's delve into the details.

In the initial six months of 2025, the U.S. faced 14 separate weather-related disasters, each inflicting at least $1 billion in damage. Climate Central's calculations reveal a staggering $101 billion in total damages. This figure surpasses any other first half of a year since such records began in 1980.

The primary culprit behind this financial burden was the ferocious wildfires that ravaged parts of Los Angeles in January. This single event destroyed around 16,000 buildings and indirectly led to approximately 400 deaths. The LA fires alone cost $61 billion, making it one of the most expensive climate-related disasters in U.S. history and the only one in the top 10 not caused by a hurricane.

But here's where it gets controversial: This alarming trend was meticulously tracked by the National Oceanic and Atmospheric Administration (NOAA) for 45 years. However, the Trump administration discontinued this crucial data set in May, citing "evolving priorities." This decision has raised significant concerns, as this information serves as a critical barometer of the climate crisis and a vital planning resource for cities and states facing increasing extreme weather threats.

Climate Central has stepped in to fill this void, recognizing the urgent need for updated information. Adam Smith, who previously led the billion-dollar disaster project at NOAA, now spearheads this effort at Climate Central, using the same methodology. He emphasizes the increasing frequency and intensity of these costly events since 2017, attributing it to climate change.

And this is the part most people miss: The initial Climate Central update ends in June, so it doesn't include the deadly floods in Texas in July, which claimed over 130 lives. Additionally, the U.S. has been fortunate enough to avoid a major hurricane so far this year. Experts note that this luck may not last, especially with the Trump administration's efforts to dismantle disaster response systems.

The Federal Emergency Management Agency (FEMA) has faced criticism for staff reductions and a perceived lack of preparedness. There are also claims of politically motivated withholding of funds. Samantha Montano, an emergency management expert, highlights the "tremendous concern" due to the growing threat of climate-fueled disasters, population shifts to risky areas, and inadequate infrastructure. She notes that improvements made to FEMA after Hurricane Katrina have been reversed, leaving local and state agencies struggling to cope. Montano warns that the U.S. is essentially "sitting ducks" for the next major disaster.
