The Milankovitch theory has come to function as "shorthand" for the orbital forcing or pacing of climate change, Milankovitch cycles for any orbital cycle affecting climate (on any planet). Called Milankovitch cycles, they are due to the gravitational influence of the moon and planets. That seems like a higher priority, doesnt it? Deglacial temperature history of West Antarctica.

Milankovitch cycles do not complicate the scientific observation that human-released CO2 is causing an observable net increase in global temperatures. Man has had a deadly affect on sea life and only intensive remediation and aquaculture can turn things around. As accurately copied and pasted from NASAs website, Milankovich cycles do indeed describe three periodic variations in the way the Earth rotates around the sun. Eccentricity is, simply, the shape of the Earths orbit around the Sun. 1Pe7#fV7'y9M THAT is science. Your comments seem reasonable and simply suggest self education.

Notwithstanding very divergent conditions, life flourished both during the Eocene Optimum and the Ice Age, though in both cases life was more abundant in some parts of the world than in others. QUESTION: Mr. Armstrong; I just read your report on the Maya discovery of time and the flipping of the poles. The geological record of ancient climate is excellent.

Evidence abounds that the cycles did occur for the last 500,000 to 800,000 years. The tilt changes from a range of 22.1 to 24.5 degrees over a period of a 41,000-year cycle. Anthropomorphic climate change is just to be accepted or you then are labeled a heretic or a denier. according to milankovitch theory, the precessionof the equinoxesand the apsides, variations in the tilt of the earth's axis (obliquity) and changes in the eccentricityof the earth's orbit are responsible for causing the observed 100 kyr cycle in ice agesby varying the amount of sunlight received by the earth at different times and locations, Earth and Planetary Science Letters. Climate change skeptics say that human-caused CO2 emissions don't have an effect. Slow variations in Earth's orbit, called Milankovitch cycles, effect the vast, slow changes in ice sheets, glaciers, and sea level. Second, Milankovitch cycles are only one factor which will contribute to global climate change , both past and present. Hkdi^o I personally found the . From the human perspective, climate change has the potential of causing some areas to become less agriculturally productive (and therefore less inhabitable), and other to become more so. The most important lessons drawn from geology are that the earths climate can change radically and that the pace of change can be rapid. Born in 1879 in the rural village of Dalj (then part of the Austro-Hungarian Empire, today located in Croatia), Milankovitch attended the Vienna Institute of Technology and .

The geological evidence is very strong that sea level was higher by about 200 feet at times, such as during the Eocene Optimum, when Antarctica was ice-free, and was about 400 feet lower during the height of the Ice Age. ANSWER: We are definitelyin that zone where the poles will flip. See Also Ice Ages; Millennial Climate Oscillations. But these fluctuations in sunlight arent enough on their own to bring about full-blown ice ages and interglacials. <>
The range is enormous; the worlds coastlines are radically altered by such changes. So we are increasing the levels of CO2 and other GHG significantly, while decreasing the ability for it to be naturally taken back out of the atmosphere. Your membership is the foundation of our sustainability and resilience. This journalistic scoop did not come from a whistleblower or leaked documents, Turner stated, but from a 20-year-old educational feature on NASAs publicly accessible online magazine, Earth Observatory: On its Earth Observatory web site, NASA published in the year 2000, the information they possessed about the Milankovitch Climate Theory, which was PROVED to be fact by core samples from the earth's seas.

Further as the article states CO2 levels have seen an increase in climbing rates as we entered the industrial revolution, we have also seen an increase in other areas during this same time as a direct result. A log graph showing the comparative rates-of-change might do wonders for educating those rare individuals still amenable to education. The variation in that estimate is wide, and could be hundreds of thousands of barrels. Thus, for instance, had the Antarctic been glaciated during the Eocene Optimum (and the geological evidence is that it was ice-free), the world would have been somewhat cooler due to the high reflectivity of the ice. Dr. Menkes article backs what my belief has been for decades. This can also be seen in the temperatures associated with the Vostok ice core on the graph to the right of the earth's orbit. at the start of the glaciations to 400-700 p.p.m. The last of these ices ended around 20,000 years ago.

One school of thought is the current global warming is only due to the Milankovitch Cycles and sunspots. These measurements are consistent with modeling results, which give a threshold of about 780 p.p.m. Milankovitch cycles do not complicate the scientific observation that human-released CO2 is causing an observable net increase in global temperatures. Lets calculate how many years it took at the. Would like to add this about Brian's control theory of global warming fearology (that climate fears allow the conspirators to control the masses).

It takes a complete picture to formulate any plan to survive the future climatological human environmental habitat adjustment needed, not some screaming extortionist that cant even answer a simple question about a millionfold problem. Other important factors include: the amount of water vapor (another greenhouse gas) in the atmosphere; the percentage of the sky covered by clouds, which reflect sunlight back into space; the percent of land covered with ice and snow, which are also very reflective; and the percentage covered by oceans and and forests, which are very absorbing.

So what Im reading here is that assuming u are right that gas levels will rise with in 150 200 years to a level that melts the ice whether we change anything or not but faster if we dont and that these events are cyclical so do we make changes and entirely change our way of life or do we look at technology to offer protection from the consequences or to potentially reduce gas levels I have no qualifications in science at any level however as I see it u can either sit and wait counting down or just maybe we could look at science a clearly unscientific idea that comes to mind is what other gas could have a potentially cooling effect when added to green house gas at any rate take the money invested in to climate change and look at solutions rather than an extension.
