Scientists from Lund University (Sweden), in cooperation with the GEOMAR climate scientists Prof. Dr. Katja Matthes and Dr. Rémi Thiéblemont, have succeeded in reconstructing the solar activity back to the last ice age. The study was published in August in Nature Geoscience.

2020年2月27日 · A century ago, Serbian scientist Milutin Milankovitch hypothesized the long-term, collective effects of changes in Earth’s position relative to the Sun are a strong driver of Earth’s long-term climate, and are responsible for triggering the beginning and end of …

2007年8月23日 · The team found a correlation between ice age onsets and terminations, and variations in the season of Earth's closest approach to the sun. Earth's closest pass, or perihelion, happens to fall in June about every 23,000 years.

2014年8月18日 · For the first time, a research team has been able to reconstruct the solar activity at the end of the last ice age, around 20,000-10,000 years ago, by analysing trace elements in ice cores in...

2024年10月23日 · "Pink elephant in the room" time: There is no impending “ice age” or "mini ice age" if there's a reduction in the Sun’s energy output in the next several decades. Through its lifetime, the Sun naturally goes through changes in energy output.

2025年3月3日 · Arctic ice sheets covered most of Northern Europe and America 20,000 years ago. A new study finds ice ages are cyclical and can be predicted based on the Earth's orbit of the sun.

What triggers these periods of glaciation, or ice ages, is difficult to pin down, though for some time researchers have strongly suspected quirks of Earth's orbit around the Sun are involved. New research has demonstrated the precise relationship between past ice ages and each wobble, tilt, and angle of the planet's path, unlocking a new tool ...

2019年9月6日 · The Sun powers life on Earth; it helps keep the planet warm enough for us to survive. It also influences Earth’s climate: We know subtle changes in Earth’s orbit around the Sun are responsible for the comings and goings of the past ice ages.

4 天之前 · A pattern of encroaching and retreating ice sheets during and between ice ages has been shown to match certain orbital parameters of Earth around the sun, leading to researchers being able to ...

2025年2月27日 · For the past 900,000 years, every interglacial has occurred after Earth’s axis wobbled at its furthest point from the sun as the planet was also tilting closer towards the sun, following the ...
