  2. Polar climate - Wikipedia

    en.wikipedia.org/wiki/Polar_climate

    The polar climate regions are characterized by a lack of warm summers but with varying winters. Every month a polar climate has an average temperature of less than 10 °C (50 °F). Regions with a polar climate cover more than 20% of the Earth's area.

  3. Milankovitch cycles - Wikipedia

    en.wikipedia.org/wiki/Milankovitch_cycles

    Milankovitch cycles describe the collective effects of changes in the Earth's movements on its climate over thousands of years. The term was coined and named after the Serbian geophysicist and astronomer Milutin Milanković .

  4. Polar meteorology - Wikipedia

    en.wikipedia.org/wiki/Polar_meteorology

    Polar meteorology is the study of the atmosphere of Earth's polar regions. Surface temperature inversion is typical of polar environments and leads to the katabatic wind phenomenon. The vertical temperature structure of polar environments tends to be more complex than in mid-latitude or tropical climates.

  5. List of periods and events in climate history - Wikipedia

    en.wikipedia.org/wiki/List_of_periods_and_events...

    500 million years of climate change Ice core data for the past 400,000 years, with the present at right. Note length of glacial cycles averages ~100,000 years. Blue curve is temperature, green curve is CO 2, and red curve is windblown glacial dust (loess). Scale: Millions of years before present, earlier dates approximate.

  6. Solar activity and climate - Wikipedia

    en.wikipedia.org/wiki/Solar_activity_and_climate

    Climate modelling suggests that low solar activity may result in, for example, colder winters in the US and northern Europe and milder winters in Canada and southern Europe, with little change in global averages. [89] More broadly, links have been suggested between solar cycles, global climate and regional events such as El Niño. [90]

  7. Paleoclimatology - Wikipedia

    en.wikipedia.org/wiki/Paleoclimatology

    It was only in the 20th century that paleoclimatology became a unified scientific field. Before, different aspects of Earth's climate history were studied by a variety of disciplines. [5] At the end of the 20th century, the empirical research into Earth's ancient climates started to be combined with computer models of increasing complexity.

  8. Orbital forcing - Wikipedia

    en.wikipedia.org/wiki/Orbital_forcing

    Orbital forcing is the effect on climate of slow changes in the tilt of the Earth's axis and shape of the Earth's orbit around the Sun (see Milankovitch cycles).These orbital changes modify the total amount of sunlight reaching the Earth by up to 25% at mid-latitudes (from 400 to 500 W/(m 2) at latitudes of 60 degrees).

  9. Climate of Antarctica - Wikipedia

    en.wikipedia.org/wiki/Climate_of_Antarctica

    The climate of Antarctica is the coldest on Earth. The continent is also extremely dry (it is a desert [ 1 ] ), averaging 166 mm (6.5 in) of precipitation per year. Snow rarely melts on most parts of the continent, and, after being compressed, becomes the glacier ice that makes up the ice sheet .
