Global Warming Causing Storms Strong Enough to Shake the Earth

Climate change is significantly impacting our oceans and their wave patterns, leading to stronger ocean waves and heightened seismic activity. Wave heights in the Southern Ocean and North Atlantic have been on the rise, and increased storm intensity is contributing to the global microseism, a continuous hum of the Earth produced by various sources including ocean waves.

El Niño and La Niña cycles, along with other climate oscillations, play a role in the changes seen in ocean wave dynamics. The resulting coastal hazards include increased flooding, sediment transport, and potential damage to infrastructure in coastal areas.

Seismographs are useful tools to monitor these changes, as they capture both primary and secondary microseism signals generated by wave interactions. As the planet continues to warm due to greenhouse gas emissions, understanding the interplay between climate change, ocean waves, and seismic activity becomes essential for environmental protection strategies and building resilience in coastal communities.
