It rained 12 inches in just one hour, and the river rose 26 feet in only 45 minutes.
Search and rescue operations continue along the Guadalupe River in Texas after catastrophic flooding killed at least 22 people and left at least 20 girls missing, local authorities confirmed. The full scope of the disaster remains unclear as emergency crews navigate washed-out roads and unstable riverbanks while families wait for news.
The flooding followed a series of violent storms that dumped record-breaking rainfall across central Texas, transforming streets into rivers and sending walls of water down river valleys in the middle of the night. Entire communities were inundated within hours, leaving people stranded on rooftops or swept away by the current.
Events like this, once classified as "500-year floods," are no longer rare. Due to climate change, extreme rainfall events have become significantly more frequent and severe. For every 1°C (1.8°F) rise in temperature, the atmosphere holds about 7% more water vapor, fueling heavier downpours when storms occur. What was once a flood expected twice in a millennium now occurs every five to ten years in many regions.
Violent rain is just one facet of the climate crisis. Warming oceans, disrupted jet streams, and intensified atmospheric rivers are driving a sharp increase in the frequency and severity of extreme weather events globally, transforming what were once rare "freak" occurrences into the new normal. Communities across Texas and beyond are already experiencing these impacts, with mounting human and economic costs.
Texas has quickly become one of the most challenging states in which to find reasonably priced insurance. As climate risks accelerate, insurance companies are withdrawing from high-risk areas, leaving many Texans unable to obtain coverage at any price. In some regions of the state, insurance is no longer available at all, leaving families and businesses vulnerable to devastating losses as extreme weather events become more frequent and severe.
Exponential Acceleration: The Shrinking Climate Doubling Period
Recent research on climate system “doubling periods“ reveals that what once took 100 years to worsen is now accelerating to as little as 2-5 years. Heatwaves are already five times more likely due to current warming, projected to become 10 times more likely within five years and 20 times more likely within a decade if emissions and feedback loops continue unchecked. This acceleration is not a theoretical abstraction: it is driven by the non-linear collapse of systems such as the AMOC, jet streams, and global hydrological cycles, creating conditions for more intense, frequent, and deadly storms and floods. Traditional climate models continue to underestimate these compounding, cascading effects, leaving communities unprepared for disasters like the floods devastating Texas.
Policy Failures and the Cost of Climate Denial
The severity of this disaster is not just a product of nature but of policy choices. The Trump administration's sustained climate denial, efforts to discredit scientific institutions, and defunding of agencies such as NOAA and the National Weather Service have deeply undermined the nation's ability to prepare for and respond to extreme weather events. By ending investments in clean energy, cutting climate research, and silencing scientific guidance, the administration has left communities across the United States vulnerable to a rapidly intensifying climate crisis. The Texas floods are yet another tragic reminder that ignoring science has deadly, escalating costs--turning preventable disasters into national tragedies.
Closing Thought
As search efforts continue, the tragedy unfolding along the Guadalupe River is a stark reminder that climate change is not a distant threat but a current reality reshaping safety and security across the United States. It calls for urgent investment in resilient infrastructure and a transition away from fossil fuels, whose continued use is supercharging storms, flooding, and other extreme weather events.
