  10. 10. 3 . Astronomical theory of climate changes and its application in geophysics INTRODUCTION <ul><li>Two natural laws: </li></ul><ul><li>Newton’s law of gravity applied on planets’ motion </li></ul><ul><li>b) “Geometric law” of Sun irradiation of the Earth </li></ul><ul><li>By mathematical language it is possible to describe relationship with Earth’s motion parameter variations and its Sun’s irradiation variations </li></ul>
  11. 11. 3 . Astronomical theory of climate changes and its application in geophysics INTRODUCTION <ul><li>In the book a “part of the science is exhibited which can find many applications in geology and geophysics” </li></ul><ul><li>The first pat of the book is devoted to the theory and the second to the applications without strong mathematic – readable for the people without strong mathematical background. </li></ul>
  12. 12. 3 . Astronomical theory of climate changes and its application in geophysics PART I - Theory Scheme of the Earth orbital element changes
  13. 13. 3 . Astronomical theory of climate changes and its application in geophysics PART I - Theory Ilustration of annual course of Earth iradiation on a paralel <ul><li>Lasting of a year divided into two equal parts: warm and cold part </li></ul><ul><li>summer temperature important for ice ages </li></ul>
  14. 14. 3 . Astronomical theory of climate changes and its application in geophysics PART I - Theory Material embedded in the ice sheet is deposited at the terminus to form moraine. Geologists use them for ice age study.
  15. 15. 3 . Astronomical theory of climate changes and its application in geophysics PART I - Theory Geologists use moraines for ice age study.
  16. 16. 3 . Astronomical theory of climate changes and its application in geophysics PART II - Application Figure 15. Oscillations of amplitudes of summer irradiation for 65 degree parallel (After Milanković, 1948) Figure 12. Distribution of glacial and interglacial episodes (After Penck, 1932)
  17. 17. 3 . Astronomical theory of climate changes and its application in geophysics PART II - Application “ If schemes from Figures 12 and 15 are compared then an extraordinary agreement between them is obvious although they have been obtained on two quite different ways: by geological study and astronomical calculations, respectively. Then, Austrian meteorologist Köppen confimed how in my calculations a fully appearing of four Alpine ice ages of Penck-Brückner scheme, what very soon has been accepted by Brückner himself.”
  18. 18. 3 . Astronomical theory of climate changes and its application in geophysics PART II - Application “ Our citizenship calendar is in principle an accounting of space events. In its elements as: day, month and year are all space events: rotation of the Earth, Moon moving around Earth and the Earth moving around the Sun. The same situation is with the “calendar” of Earth past i.e. with obtained irradiation c u rves. Within the space events of higher categories are reflected:: obliquity of Eart´s axis, eccentricity of the orbit and precession.”
  19. 19. 3 . Astronomical theory of climate changes and its application in geophysics PART II - Application “ High position of ice c o ver preserves its from melting in shorter intermediate ice ages between Ginc and Mindel as well as Ris and Virm. During a longer intermediate period between Mindel and Ris ice melting has been at the whole. The s now c o ver on the Greenland by his high elevation is able to resist warmth of Sun’s rays.”
  20. 20. 3 . Astronomical theory of climate changes and its application in geophysics PART II - Application Greenland in Summer
  21. 21. 4. Scientific echo of Milankovic’s astronomical theory of ice ages <ul><li>Broecker (1968), 10 years after Milanković’s death said: </li></ul><ul><li>“ Milanković’s theory can not be considered as a curiosity. A serious attention should be devoted to this theory.” </li></ul>
  22. 22. 4. Scientific echo of Milankovic’s astronomical theory of ice ages “ Hays et al. (1976), according to “records” in oceans confirmed Milankovi c ’s astronomical theory of ice ages: “ It is concluded that changes of Earth orbital geometry are basic cause of quaternary ice age cycle. The m odel of future climate based on the orbital-climate relationship, ignoring the human influence, indicate a trend to the colder climate on the northern hemisphere in around next twenty thousands years.”
  23. 23. 4. Scientific echo of Milankovic’s astronomical theory of ice ages Comparison of Solar forcing and stage of glaciations
  24. 24. 4. Scientific echo of Milankovic’s astronomical theory of ice ages Milanković’s irradiation c u rve for the Northern pole for past 250 and future 50 thousands years
  25. 25. 4. Scientific echo of Milankovic’s astronomical theory of ice ages Recent global warming climate scenario, very probably under strong human influence
  26. 26. 4. Scientific echo of Milankovic’s astronomical theory of ice ages “ It can be noticed that climate change as resuts of greenhouse gaseous are also “forced” by changes of radiation regime at the top of the atmosphere. These change are not principally different (although differently distributed) form changes which are caused by Milanković’s “forcing”. Therefore it can be concluded that influence of greenhouse gaseous will results in great extent a predictable climatic response.” <ul><li>Houghton (2002): </li></ul>
  27. 27. 5 Conclusion <ul><li>There is not contradiction between Milanković’s astronomical theory of climate changes and recent global warming theory but only difference is in time scale and causes of climate changes. </li></ul>
