May 26, 2022 Scientists have finally put to bed a long-standing question over the role of Earth's orbit in driving global ice age ...
Sep. 13, 2023 A pioneering study has shed new light on North African humid periods that have occurred over the past 800,000 years and explains why the Sahara Desert was periodically ...
Oct. 3, 2022 Scientists have made a key breakthrough in the quest to accurately predict fluctuations in the rotation of the Earth and so the length of the day -- potentially opening up new predictions for the ...
Dec. 13, 2022 Changes in Earth's orbit that favored hotter conditions may have helped trigger a rapid global warming event 56 million years ago. Researchers found the shape of Earth's orbit, or ...
June 3, 2021 Seismic waves generated by earthquakes travel through Earth's solid iron inner core faster in the direction of the rotation axis than along the equator. Scientists created a core growth model to ...
Sep. 15, 2022 To improve understanding of variation of Earth's rotation in the 4th--7th centuries CE, a research team analyzed Byzantine records from this period to identify total solar eclipses around the ...
May 15, 2023 A research team, composed of climatologists and an astronomer, have used an improved computer model to reproduce the cycle of ice ages (glacial periods) 1.6 to 1.2 million years ago. The results show ...
May 16, 2023 A team of physicists has discovered a new role for a specific type of turbulence -- a finding that sheds light on fluid flows ranging from the Earth's liquid core to boiling ...
Nov. 9, 2022 Earth is closer to the sun at some times of year than at others, with the time of closest approach shifting over a period of 22,000 years. This affects Earth's climate, including ice ages, but a ...
Aug. 5, 2021 Understanding the Sun's magnetic dynamo could help predict solar weather, such as potentially dangerous geothermal storms, solar flares and sunspots. Mathematicians have proposed a new model of ...
