Our Impact on the Earth

“Mother Nature is not happy right now and she’s trying to tell us, in many ways,” says Kimberly Prather, Professor of Climate, Atmospheric Science, and Physical Oceanography at UC San Diego.

New weather patterns and events are causing concern but how do we know these changes are caused by human activity? Climate scientists are looking at trends over time to determine our impact on the planet.

Prather discusses recent CAICE studies aimed at advancing our understanding of how the oceans influence human and planetary health including novel experiments being conducted in a unique ocean-atmosphere simulator.

Tuning into the Sounds of Our Dynamic Planet

Did you know there are unheard sounds in the Earth’s atmosphere that can travel all the way around the world?

Dr. Michael Hedlin of UC San Diego’s Scripps Institution of Oceanography explains that when massive events occur in the atmosphere low frequency sounds are generated that can be received all over the earth, depending on the magnitude of the event. Much like when there is an earthquake and seismic waves can be read on seismometers around the planet.

Although we cannot hear these sounds because of their low frequencies, there is still a lot they can tell us about things like volcanic eruptions and meteorite impacts.

Listen in as Michael Hedlin discusses what we can learn from the Earth’s atmosphere’s frequencies in “Listening to Earth’s Atmosphere: Tuning into the Sounds of Our Dynamic Planet”
