The human history of Greenland is deeply intertwined with climate cycles, particularly the shifts between warmer and colder periods. During the Medieval Warm Period (around 900-1300 AD), Norse settlers thrived, establishing farms and communities. However, the subsequent Little Ice Age led to harsher conditions that contributed to the decline and eventual abandonment of these settlements. This pattern illustrates how climate fluctuations have influenced human habitation, adaptation, and survival in Greenland over the centuries.

Changes in the amount of energy the sun sends out may be related to solar activity cycles, such as sunspot cycles, solar flares, and coronal mass ejections. These cycles can impact the amount of solar radiation reaching Earth and can influence our climate and space weather.
It isn't, really. Yes, the Earth has been warming, since the 1820's. Before that it was cooling, from the late 1600's, and before that it was warming. The world's climate goes in cycles; not only the annual cycles of winter and summer, but cycles hundreds, perhaps a thousand years long. A thousand years ago, the world was warmer than it is now! There were dairy farms on Greenland, and the Vikings called it "Greenland" because it was green. Lief Erikson discovered a land with grape vines which he called "Vinland" (Not big on innovative names, those Vikings). We've discovered Vinland; it's in Labrador, Canada. No grape vines.
Earth climate history can be studied by analyzing various sources such as tree rings, ice cores, sediment layers, and fossils. These sources provide information on past temperatures, precipitation levels, atmospheric composition, and overall climatic conditions over geological time scales. By studying these records, scientists can gain insights into past climate variations, natural climate cycles, and the impacts of human activities on the environment.
Because Milankovitch cycles cannot explain climate variability over the time scale that we're interested in predicting climate. Milankovitch cycles can explain large variations in climate over very long time scales, scales of thousands of years. Milankovitch cycles do not explain variability in climate on the scales of hundreds or tens of years. Variability at smaller time scales is driven by other factors, such as carbon dioxide (CO2) and other greenhouse gas concentrations.
solar cycles and ocean currents are two of the main things
Frost wedging would be more likely in Thule, Greenland due to its colder climate and prolonged periods of freezing temperatures. The extreme cold conditions in Greenland would promote the repeated freezing and thawing of water in cracks and crevices, leading to the gradual breakdown of rock through frost wedging. Butte, Montana also experiences freezing temperatures, but the intensity and duration of cold in Thule would make frost wedging more prominent there.
The Sun undergoes several cycles, the most notable being the solar cycle, which lasts about 11 years and involves fluctuations in solar activity, including sunspots, solar flares, and coronal mass ejections. Additionally, there are longer cycles related to solar magnetic activity, such as the Hale cycle, which spans about 22 years and involves the reversal of the Sun's magnetic poles. These cycles influence space weather and can impact Earth's climate and technology.
No one is responsible. It is just nature. Climate change has been happening for millions of years. The earth goes through cycles.
the theory of birhythm claims that one's life is affected by rhythmic biological cycles, and seeks to make predictions regarding these cycles and the personal ease of carrying out tasks related to the cycles.
Clots are not related to menorrhagia, although women with heavy cycles may pass clots.
