Tornados, floods, and thunderstorms oh my!
Shade Academia Weekly Newsletter- Natural Sciences
Happy Monday everyone!
We hope to get you off to a great start this week with an interesting piece. During this time of the year, things get a little crazy in the Midwest, home to our Shade Academia team. Flooding, tornadoes, and severe thunderstorms happen every week! With the upcoming “Twisters” movie, I wanted to dive into our current situation and how the climate has changed tornadoes, storms, and weather as we know it. Grab a nice cup of coffee or your beverage of choice and enjoy today's reading as you prepare for the rest of your week.

Climate change, bad weather, and the United States:
Have you ever wondered how climate change has influenced the occurrence and severity of natural hazards in the U.S. over two decades? A recent study titled "Observed Changes in the Frequency, Intensity, and Spatial Patterns of Nine Natural Hazards in the United States from 2000 to 2019" by the U.S. Environmental Protection Agency investigates how climate change has influenced the occurrence and severity of natural hazards in the U.S. over two decades. This research provides empirical evidence supporting the hypothesis that climate change is altering natural hazard patterns.
The researchers compiled county-level time-series datasets for nine natural hazards, including hurricanes, tropical storms, landslides, wildfires, earthquakes, drought, inland flooding, coastal flooding, and tornadoes. Using geospatial analysis, they assessed changes in the frequency, intensity, and spatial distribution of these hazards. The data revealed significant changes in the frequency and intensity of hurricanes, tropical storms, and droughts, linked to climate change. However, tornadoes, landslides, and wildfires did not show significant frequency changes, likely due to their site-specific nature.
The science behind these changes lies in how a warming climate affects atmospheric conditions. As global temperatures rise, the atmosphere can hold more moisture, leading to increased instability. This instability can result in more frequent and intense hurricanes and tropical storms. Similarly, higher temperatures can exacerbate drought conditions by increasing evaporation rates and reducing soil moisture. However, for hazards like tornadoes, which require specific conditions like wind shear, the influence of climate change is less straightforward and more localized.
The study found that hurricanes, tropical storms, and droughts have become more frequent and intense, supporting the theory that climate change impacts these hazards. While tornadoes, landslides, and wildfires showed significant spatial trends and hot spots, their frequency did not change significantly. Coastal and inland flooding also demonstrated connections to climate change, although data limitations prevented conclusive statistical testing.
Impact on Future Research and Policy:
These findings highlight the need for updated risk assessments and disaster preparedness strategies that account for the changing patterns of natural hazards due to climate change. The study’s novel approach using county-level data can serve as a model for future research and aid policymakers in developing more resilient infrastructure and emergency response plans.
The research provides critical empirical support for the link between climate change and changes in natural hazard patterns. As climate change continues to influence weather and environmental conditions, ongoing monitoring and analysis will be essential to mitigate the risks associated with natural hazards and protect vulnerable communities. Policymakers and planners must prioritize adaptive strategies that enhance resilience against these evolving threats. By integrating climate projections into urban planning, infrastructure development, and emergency management, we can better prepare for future challenges. Additionally, increasing public awareness and education about the implications of climate change on natural hazards will be crucial. Collaboration between scientists, government agencies, and communities will ensure that our responses are effective and comprehensive, safeguarding lives and property against the growing impacts of climate change.
Deeper Thinking Questions
- How can local governments and communities use the findings of this study to improve disaster preparedness and response plans?
- What additional data or research would be necessary to fully understand the impact of climate change on site-specific hazards like tornadoes and landslides?
- How might changes in natural hazard patterns due to climate change affect economic and social stability in affected regions?
