We already know that the eccentricity of the earth is synchronized with the glacial cycles. Although initially less influential, French researchers have found that it controls the evolution of marine life and the climate in general. Here’s how it works.
About fifty years ago, researchers discovered. Thus, the cycles between one for the last 400,000 years Synchronized over a period of time Earth’s atmosphere for about 100,000 years. It may come as a surprise that such a small variation has such an impact on them : Changes in the Earth’s orbit affect 10,000 times less than its magnitude. Accepted (for example it depends ). Over the years, researchers have wondered what could be contributing to the increase in these climate changes.The earth (see box) has been standing next to it
Skeletons of algae to study biodiversity
In a new study published in , Luke Beaufort and his colleagues from CNRS, Marseille, expressed interest. Analysis of variations with the weather of the rocks at the time , Especially changes in the structure of coccyx, these structures Which cover . Each of these gives a good overview of the diversity of phytoplankton Forming a distinct coccyx.
Used by researchers, To artificially accelerate the process of chocholith formation. They later discovered more phytoplankton different slavery over the Earth’s eccentricity. In fact, the more the left, the more The seasonal population is very large, which helps to increase the number of ecological sites and thus increase the phytoplankton diversity., To be more precise, a mighty one
A feedback loop that increases climate change
Other elements are likely to play in this feedback loop. The retreat of glaciers and islands, for example, can create segregated habitats and create more space, which accelerates the turnover rate of phytoplankton. ” A link between orbital change, climate and phytoplankton trends may be an internal rhythm underlined by the Earth system. Rosalind Riccibe, a biologist at Oxford University, concludes . The best example of the famous butterfly effect.
