milankovitch cycles

     

Milankovitch cycles are the collective effect of changes in the Earth's movements upon its climate, name after Serbian civil engineer and mathematician Milutin Milanković. The eccentricity, axial tilt, and precession of the Earth's orbit vary in several patterns, resulting in 100,000-year ice age cycles of the Quaternary glaciation over the last few million years. The Earth's axis completes one full cycle of precession approximately every 26,000 years. At the same time, the elliptical orbit rotates, more slowly, leading to a 21,000-year cycle between the seasons and the orbit. In addition, the angle between Earth's rotational axis and the normal to the plane of its orbit moves from 22.1 degrees to 24.5 degrees and back again on a 41,000-year cycle. Currently, this angle is 23.44 degrees and is decreasing.

  • Wondering if anyone is taking the time to get educated on Milankovitch Cycles this week? #climatechange
  • @djmer1 What is your opinion on Milankovitch cycles.
  • @SlagOffTwits I stand by my statements. Once you understand the carbon cycle & milankovitch cycles, get back to me so we can debate science
  • @MarkRuffalo @LeoDiCaprio Climate cycles are natural, mainly created by Milankovitch cycles
  • You guys have heard of the Milankovitch cycles right? When does emotion > science? #FloodWallStreet
  • @LoisSalem get dem milankovitch cycles goin doe

  • @richardbranson Would be a shame if we skyrocket energy costs then find out anthropogenic CO2 isn't a factor, it's all Milankovitch cycles
  • @topdeck55 Milankovitch cycles include all 3 types of forcings.

  • If you don't understand the carbon & milankovitch cycles you have no business debating climate change. Especially if you refuse to learn.
  • @SlagOffTwits If you don't understand the milankovitch cycles and carbon cycle you have nothing to add to this debate.
  • “@TheOnion: 7.1 Billion Demonstrate In Favor Of Global Warming Check Milankovitch cycles.
  • @SlagOffTwits Go read about the Milankovitch cycles, and the carbon cycle.
  • @SlagOffTwits According to the milankovitch cycles we should be cooling and CO2 should be decreasing.
  • @RobertKennedyJr Climate cycles are natural, CO2 lags temps, Milankovitch cycles = main cause
  • @MarkRuffalo Learn 2 things: CO2 lags temp changes & climate cycles are natural, primarily from Milankovitch cycles
