Slowdown of North Atlantic circulation caused sudden cold spells lasting hundreds of years

A new study from the University of Helsinki in Finland reports that sudden cold spells lasting hundreds of years took place in the middle of the warm Eemian climate period, about 120 000 years ago, as a result of the slowdown of the North Atlantic circulation....

Study of Earth's magnetic field reversals reveals 405 000-year climate cycle

Gravitational tugs from Jupiter and Venus slightly elongate Earth's orbit every 405 000 years, an amazingly consistent pattern that has influenced our planet's climate for at least 215 million years. This pattern allows scientists to more precisely date...

Our star is rotating on a helical orbit while spiraling up and down (spiral oscillation)

According to my understanding, all structures in the Universe, including the largest one, are magnetically ordered and centrally powered. The Milky Way follows this standard cosmic model. The astronomical objects and celestial bodies of our galaxy are connected to...

Natural cycles: A link between formation of supercontinents and strength of ocean tides

A new study suggests there is a likely link between the cyclic strengthening and weakening of ocean tides over tens of millions of years and another, longer cycle - the formation of Earth's supercontinents every 400 to 600 million years. The new research...
