Federal disaster reports under the Trump administration leave journalists to source climate explanations elsewhere

NASA and NOAA analyses still provide detailed meteorology, trends, and preparedness information while omitting explanations of human-caused warming that earlier federal accounts included

On September 9, the National Oceanic and Atmospheric Administration announced that the contiguous United States had experienced its hottest summer in 132 years of records. Its public summary provided readers, including journalists, with detailed information about record temperatures and expanding drought, but it did not explain how human-caused warming contributed to the conditions it described.

The same pattern appears in NASA’s report on July’s western heat wave and NOAA’s analysis of the July 2025 Texas floods. Across these examples, federal agencies continued to provide detailed information about the meteorology, broken records, damage, and in some cases worsening long-term trends without explaining how climate change had increased those risks.

These omissions are not isolated. The Trump administration has also disrupted other federal sources of information the public relies on to understand climate risk. In April 2025, it terminated the contract supporting the coordinating office of the U.S. Global Change Research Program, which produces the National Climate Assessment. NOAA also stopped updating its billion-dollar disaster database, and Climate.gov stopped publishing after its entire staff was laid off. 

Journalists have used that research to explain extreme weather. In October 2024, MSNOW’s (then-MSNBC’s) All In with Chris Hayes referenced NOAA’s billion-dollar disaster data during an interview with agency climatologist Adam Smith. Smith explained that billion-dollar disasters had become much more frequent since the 1980s. He described how climate change adds heat to the ocean and atmosphere, contributing to extreme weather — including heavier rainfall — and noted that communities’ exposure and vulnerability compound the damage.

The billion-dollar database, Climate.gov, and the assessment program are gone. The analyses that remain are as detailed as ever — what the reports examined here no longer explain is why.

Federal climate analyses can shape reporting even when they do not appear in a published story or on-air segment. Journalists may consult them to understand an event, prepare for interviews, identify relevant questions, or check their own understanding before writing or going on air. When those accounts do not explain how climate change is contributing to the extreme weather they describe, reporters have to find that explanation elsewhere, and it may never make it into the published story.

NASA’s 2026 heat-wave analysis omitted the climate explanation previously included in its 2024 analysis

The western heat wave described in NASA’s July 15 report struck when a heat dome settled over the northern Rockies. NASA reported all-time temperature records at sites in Montana, Wyoming, and Utah, along with a tenfold increase in the rate of heat-related emergency department visits across the Mountain states during the July heat.

NASA explained how the high-pressure system trapped hot air and suppressed clouds and precipitation. Its account also placed the event within a longer-term trend, noting that “heat waves like this one have become more frequent in the United States in recent decades” and that summer heat waves “roughly doubled in number between 1980 and 2023, increasing from an average of two to four per month.”

NASA omitted the climate explanation despite contemporaneous analyses linking the same mid-July 2026 heat wave to human-caused warming. Climate Central found that human-caused climate change made the extreme heat “at least three times more likely” across large parts of the western and northern United States from July 13 through July 15, affecting more than 118 million people west of the Mississippi. 

Climate Central later found that nearly half of the contiguous United States experienced temperatures “made at least five times more likely by climate change” during the mid-July heat wave.

The omission was not limited to 2026. In its June 26, 2025, account of a heat wave across the Midwest and Northeast, NASA likewise described the heat dome, broken temperature records, dangerous humidity, and widespread heat warnings, but it did not explain how global warming contributed to the extreme heat.

During a comparable eastern heat wave in June 2024, NASA combined descriptions of the meteorology, broken records, health effects, and long-term heat trends with a direct climate explanation. The agency noted at the time that the “frequency and intensity of heatwaves have increased in recent decades because of the rising concentrations of greenhouse gases in the atmosphere. They expect these increases to continue in the future.”

NOAA’s 2025 Texas flood analysis did not address how warming is changing extreme rainfall

In July 2025, catastrophic flash floods swept through the Texas Hill Country, including communities along the Guadalupe River. By July 23, the reported death toll from the floods was at least 137 people.

NOAA’s analysis, first published on August 11, 2025, described the conditions that set the stage for the flooding, including prolonged drought and an influx of tropical moisture, before detailing the intense rainfall and damage that followed. The report did not connect the extreme rainfall to human-caused climate change.

But that climate connection was well established when the Texas floods struck in 2025. In a July 9, 2025, article about the floods published by The Texas Tribune, University of South Carolina climate scientist Claudia Benitez-Nelson explained that warmer air holds more moisture, enabling heavier rainfall. “Climate change is turning ordinary weather into these disasters,” she said. Climate Central also explained how global warming contributes heavier rainfall. 

Earlier federal accounts of extreme flooding did make that connection, though. In an August 3, 2022, report on catastrophic flooding in St. Louis and eastern Kentucky, NASA explained that “once-rare events are becoming more likely as Earth’s atmosphere warms and can hold more moisture.”

Journalists are left to supply the climate context federal accounts omit

From June 29 through July 26, 2026, ABC, CBS, and NBC aired 194 segments about three major heat events without mentioning climate change, according to a Media Matters analysis. These events included the mid-July heat dome described by NASA. Viewers received forecasts, warnings, public health information, and reports of broken records without an explanation of how human-caused warming was intensifying heat.

Federal climate information has previously helped journalists provide that missing context. During the July 12, 2023, episode of CNN’s Early Start, a correspondent report used the National Climate Assessment to explain how extreme flooding events are becoming more frequent and devastating. A few months later, a November 14 CBS Evening News segment about the National Climate Assessment discussed why the effects of climate change in the United States were “far-reaching and worsening,” highlighted the growing frequency of billion-dollar weather disasters, and connected U.S. greenhouse gas emissions primarily to the burning of fossil fuels. 

Journalists can obtain climate explanations from other sources, including attribution researchers who provide rapid, event-specific analysis about how global warming is driving extreme weather. But that work does not replace climate context in federal accounts that reporters may already be consulting as authoritative background. When those accounts leave the connection out, more of the explanatory work shifts to newsrooms, where journalists must first recognize the gap before seeking out additional research and integrating it into their reporting.

If that additional reporting does not happen, audiences can receive detailed coverage of worsening heat, floods, and other disasters without understanding why those risks are increasing. The event, the damage, and even the worsening trend can remain visible while the human cause disappears.
