Nebitno...Ima još toga što će se dogoditi, pa to zahlađenje i neće imati nekakvu veliku ulogu...

Ako je i istina to, ni prvo ni zadnje ledeno doba...

po mojin kalkulacijama je 97,2%

Milutin Milanković

Milankovitch cycles describe the collective effects of changes in the Earth's movements on its climate over thousands of years. The term is named after Serbian geophysicist and astronomer Milutin Milanković. In the 1920s, he theorized that variations in eccentricity, axial tilt, and precession of the Earth's orbit resulted in cyclical variation in the solar radiation reaching the Earth, and that this orbital forcing strongly influenced climatic patterns on Earth.

Milankovićevi ciklusi

Milankovićeva teorija opisuje kolektivne klimatske učinke promjena u gibanju Zemlje. Imenovani su po građevinaru i matematičaru Milutinu Milankoviću. Konkretno, radi se o matematičkoj teoriji koja povezuje klimatske promjene s promjenama u ekscentričnosti orbite, nagibom osi i precesijom.

Zemljinoj osi za puni ciklus precesije treba oko 26.000 godina. Istovremeno eliptična orbita također rotira u ciklusu koji traje 23.000 godina. Također, kut između zemlijine osi rotacije i normale na orbitalnu ravninu oscilira između 22,1 do 24.5° s periodom 41.000 godina. Trenutno taj kut iznosi 23,44° i opada.

Milutin Milankovitch

Using these three orbital variations, Milankovitch was able to formulate a comprehensive mathematical model that calculated latitudinal differences in insolation and the corresponding surface temperature for 600,000 years prior to the year 1800. He then attempted to correlate these changes with the growth and retreat of the Ice Ages. To do this, Milankovitch assumed that radiation changes in some latitudes and seasons are more important to ice sheet growth and decay than those in others. Then, at the suggestion of German Climatologist Vladimir Koppen, he chose summer insolation at 65 degrees North as the most important latitude and season to model, reasoning that great ice sheets grew near this latitude and that cooler summers might reduce summer snowmelt, leading to a positive annual snow budget and ice sheet growth.

But, for about 50 years, Milankovitch's theory was largely ignored.

Then, in 1976, a study published in the journal Science examined deep-sea sediment cores and found that Milankovitch's theory did in fact correspond to periods of climate change (Hays et al. 1976). Specifically, the authors were able to extract the record of temperature change going back 450,000 years and found that major variations in climate were closely associated with changes in the geometry (eccentricity, obliquity, and precession) of Earth's orbit. Indeed, ice ages had occurred when the Earth was going through different stages of orbital variation.

Since this study, the National Research Council of the U.S. National Academy of Sciences has embraced the Milankovitch Cycle model.

...orbital variations remain the most thoroughly examined mechanism of climatic change on time scales of tens of thousands of years and are by far the clearest case of a direct effect of changing insolation on the lower atmosphere of Earth (National Research Council, 1982)

Orbital Variations
Changes in orbital eccentricity affect the Earth-sun distance. Currently, a difference of only 3 percent (5 million kilometers) exists between closest approach (perihelion), which occurs on or about January 3, and furthest departure (aphelion), which occurs on or about July 4. This difference in distance amounts to about a 6 percent increase in incoming solar radiation (insolation) from July to January. The shape of the Earth’s orbit changes from being elliptical (high eccentricity) to being nearly circular (low eccentricity) in a cycle that takes between 90,000 and 100,000 years. When the orbit is highly elliptical, the amount of insolation received at perihelion would be on the order of 20 to 30 percent greater than at aphelion, resulting in a substantially different climate from what we experience today.

šta znamo od Cezara? ti si mnogo toga pobrkao.

pričam o Milutinu Milankoviću srbinu rođenom u Dalju. jel si znao za tog lumena? nisi.

jel znaš što su i izračune milankovićevih ciklusa?

nemaš pojma evo pa čitaj:

Milutin Milanković (Serbian: Милутин Миланковић, pronounced [milǔtin milǎːnkɔʋitɕ]; 28 May 1879 – 12 December 1958) was a Serbian mathematician, astronomer, climatologist, geophysicist, civil engineer and popularizer of science. Milanković gave two fundamental contributions to global science. The first contribution is the "Canon of the Earth’s Insolation", which characterizes the climates of all the planets of the Solar system. The second contribution is the explanation of Earth's long-term climate changes caused by changes in the position of the Earth in comparison to the Sun, now known as Milankovitch cycles. This explained the ice ages occurring in the geological past of the Earth, as well as the climate changes on the Earth which can be expected in the future. He founded planetary climatology by calculating temperatures of the upper layers of the Earth's atmosphere as well as the temperature conditions on planets of the inner Solar system, Mercury, Venus, Mars, and the Moon, as well as the depth of the atmosphere of the outer planets. He demonstrated the interrelatedness of celestial mechanics and the Earth sciences, and enabled consistent transition from celestial mechanics to the Earth sciences and transformation of descriptive sciences into exact ones.

At NASA, in their edition of "On the Shoulders of Giants", Milanković has been ranked among the top fifteen minds of all time in the field of earth sciences.

Upravo to.
Inače mi je iz teksta posebno zanimljiv ovaj dio:

Ali ovaj put Zemlja se suočava sa sve jačim trendom zagrijavanja koji bi mogao utjecati i na novo mini ledeno doba. “Nadam se da će ovaj efekt nadjačati globalno zatopljenje, te tako čovječanstvu dati 30 godina da riješi problem zagađenja”, rekla je znanstvenica.
