WORLDTECHEarth shifted among five 'mega-climate' states over 539 million years, with extinctions spiking near transitions
WORLDTECH Brief: a short report of a current development, carrying only what WORLDTECH can ground in the sources below. It is expanded into a full WORLDTECH Story if further usable material becomes available.
Single source: this development was reported by Phys.org. What WORLDTECH can establish is that the report was made, and by whom. It has not been matched against a second independent organisation and has not been officially confirmed by the organisations involved.

What happened
A study led by an international team of researchers, including University of New Mexico paleobiologist Corinne "Cori" Myers, found that Earth's climate over the past 539 million years tended to remain within a small number of recurring climate states. The research also found that periods of elevated extinction, including the five major mass extinction events in Earth's history, frequently occurred as the planet transitioned between those states.
