Intensification of heat waves, disruption of the rainfall cycle or even melting of snow. These are well-known examples of the consequences of anthropogenic global warming. But there’s one that may seem a little more surprising. Researchers confirmed this today. Warming is shaking our earth.

When waves shake the earth

But the background signal that is most widespread and perhaps least known to the general public that seismometers record is, in a way, an echo of the roar of the waves. This translates to the movements that waves induce on the ocean floor. Areas where water depth is less than about 300 metres. A continuous sound lasting between 14 and 20 seconds is what researchers call a global microseism.

52 sites were studied

researchers of Colorado State University (United States) studied data collected since the late 1980s from 52 sites around the world. And they report in the newspaper today nature communication What’energyenergy Average waves increased 0.27% per year at the end of the 20th centuryI century. And also 0.35% per year since 2000. The North Atlantic waves are those that have intensified most rapidly.

More and more energy in waves with global warming

These results confirm that storms and waves become stronger as the climate warms. Researchers say oceans have absorbed about 90% of the excess HeatHeat Our greenhouse gas emissions have increased in recent decades. This extra energy can result in more destructive waves and more powerful storms. The impact is further increased due to rise in average sea level Climate changeClimate change, A new warning for the coastal population…
