Space Connect reported how EarthByters discovered that Earth’s interactions with Mars can drive deep sea circulation here on Earth. The podcast covers how geological records of the deep sea were used to discover a link between the orbits of the two planets and past global warming patterns, talking through the research and their collaboration with Sorbonne … Read more…
Mars has more influence on Earth than non-astrologers might have thought. Mars is, on average, about 225 million kilometres from Earth, which would suggest that it has little impact on our planet. Which is true, but as they say, a little goes a long way. In our recent paper in Nature Communications, we studied the history of deep … Read more…
Astronomical forcing of Earth’s climate is embedded in the rhythms of stratigraphic records, most famously as short-period (10^4–10^5 year) Milankovitch cycles. Astronomical grand cycles with periods of millions of years also modulate climate variability but have been detected in relatively few proxy records. Here, we apply spectral analysis to a dataset of Cenozoic deep-sea hiatuses … Read more…
