How Blue Carbon Hides in Coastal Wetland Soils
Blue carbon is stored by salt marshes, mangroves, and seagrass meadows, mostly in wet soils where carbon can remain for centuries.
Why Hurricane Categories Measure Wind, Not the Whole Storm
Hurricane categories rank wind speed, but storm surge, rainfall, size, and track explain why lower-category storms can still be dangerous.
Why Wet-Bulb Temperature Changes How Heat Feels
Wet-bulb temperature and WBGT explain why humid, sunny heat can overwhelm the body faster than air temperature alone suggests.
Why Urban Heat Islands Make Cities Hotter After Sunset
Urban heat islands make city blocks stay warmer after sunset as pavement, roofs, traffic, and lost shade store heat through the day.
Why Derechos Can Leave Damage for Hundreds of Miles
Derechos are long-lived thunderstorm windstorms. Learn how they form, why they move so fast, and why their damage can stretch for hundreds of miles.
How Ocean Currents Move Heat Around the Planet
Ocean currents carry heat, salt, and water across the globe, shaping climate, storms, marine life, and coastal weather patterns.
Why Hurricanes Can Strengthen So Quickly
Rapid intensification can turn a tropical storm into a much stronger hurricane in a day. Learn what fuels it and why it is hard to forecast.
Why Heat Domes Make Summer Weather Get Stuck
Heat domes form when high pressure traps hot air, blocks clouds, and lets heat build for days across the same region.
Why Coral Bleaching Turns Reefs White
Coral bleaching happens when heat stress breaks the partnership between corals and algae, turning reefs pale and putting them at risk.
Why Blue-Green Algae Blooms Spread in Summer Lakes
Learn why blue-green algae blooms spread in warm lakes, what warning signs to notice, and how nutrients, weather, and safety advisories fit together.
How Wildfire Smoke Travels Far From the Fire
Wildfire smoke can cross states and countries. Learn how plumes rise, winds carry particles, and weather decides where smoke settles.
Why Storm Surge Can Be the Most Dangerous Part of a Hurricane
Storm surge can push ocean water far inland during hurricanes. Learn why it forms, why it varies, and why warnings focus on water height.
Why Summer Sun Can Make Ozone Pollution Worse
Ground-level ozone forms when sunlight cooks pollutants from traffic and industry, making some hot afternoons harder to breathe.
How the UV Index Helps You Read Sun Risk Before Going Outside
The UV Index explains sunburn risk better than temperature. Learn what it measures, why it changes, and how to use it before going outside.
