Do you think earth orbit around the sun may be responsible for any of our climate change?

Question

We have a large change in weather when we travel just a few hundred miles on earth in any direction. What if earths orbit changed just a fraction of one degrees around the sun. It would cause a big change in the climate, like an ice age for example.
Does anyone actually keep tract of our orbit (millions of miles) to calculate if our orbit has changed and by how much? I know this occurs naturaly every few thousands of years or so ,but by how much? When we come out of an ice age, maybe it it gets a little warmer each time at its peak period. Maybe we get a little closer to the sun each time.this cycle occurs. I don't think anyone knows for sure, it's been going on for millions of years and I'm sure our orbit is not as precise as we think it is. Also keep in mind that the temperature of the sun is not always the same. It probably has it's own cycle to.

Answer 1

No.

Yes people keep track of these things.

Seriously, what is your education level in these fields? Why do you try to second guess the scientist who have spent years studying the causes of global warming?

My understanding from these experts is that there is a cyclic nature to global temperatures, but that we are moving away from the expected cycles and getting warmer. This is because we are burning huge amounts of fossil fuels.

I am really sorry if people do not like to hear this, but denying it will not make it go away.

The scientists do not know what is exactly going to happen. This is a very chaotic system and some small change may lead to a big result.

Or may not.

But. We are currently running an experiment of seeing how much CO2 it takes to really mess things up. We are running this on the only planet that we know will support life.

How badly do we really want to know the answer? How much do you want to bet that the answer is in the "whole lot more" region rather than the "just a little more"? The lives of your children?

Answer 2

That big tsunami a few years ago actually knocked the Earth about .1 degree off it's axis. Not to mention, not only is Earth warming up, but so is Mars (which the news isn't reporting). Some scientist claim humans are creating more greenhouse gases than all natural occurances. Mt. St. Helens alone, when active put out more greenhouse gases per hour, than all humanity puts out in a day. I also believe the sun is in a warming cycle. The sun is an uncontrolled nuclear reactor after all.

Answer 3

The variation in solar radiation due to eccentricities in the earth's orbit around the sun account for 2-3 orders of magnitude less effect than human induced factors. This information is presented very clearly in the most recent ICPP report on climate change.

Just as an FYI, the details of the earth's orbit is known with an incredible amount of detail.

Answer 4

Long term - yes, short term - very little.

The episodic nature of the Earth's glacial and interglacial periods within the present Ice Age (the last couple of million years) have been caused primarily by cyclical changes in the Earth's circumnavigation of the Sun. Variations in the Earth's eccentricity, axial tilt, and precession comprise the three dominant cycles, collectively known as the Milankovitch Cycles for Milutin Milankovitch, the Serbian astronomer who is generally credited with calculating their magnitude. Taken in unison, variations in these three cycles creates alterations in the seasonality of solar radiation reaching the Earth's surface. These times of increased or decreased solar radiation directly influence the Earth's climate system, thus impacting the advance and retreat of Earth's glaciers.

It is of primary importance to explain that climate change, and subsequent periods of glaciation, resulting from the following three variables is not due to the total amount of solar energy reaching Earth. The three Milankovitch Cycles impact the seasonality and location of solar energy around the Earth, thus impacting contrasts between the seasons.

Answer 5

some stable solutions here. another ingredient to think approximately is that the Earth additionally 'wobbles' on its axis. As a number of those solutions have reported, the earth tilts on its axis - 23.5 levels. It additionally wobbles - much like a childs spinning suitable. in case you may think of a line going for the time of the poles and popping out at each end - those lines could draw circles and draw a circle as this circulation happens. it is likewise very sluggish - it takes around 25000 years for it to make one 'wobble'. it relatively is partly by actuality that the Earth isn't a suited sphere, yet an oblate speroid (ie it has merely slightly bulge under the equator!) Scientists have faith that this wobble might set off ice a while etc. at recent we are on the 'heat' edge of the woble - it tallys up precise with the top of the final ice age some 15K years in the past.

Answer 6

Normal climate changes in an year ( one full orbit ) is natural, due to rotation of earth, around the Sun.

But present day changes are " man made ". All are happening in unnatural way. If it continues , the days to be numbered.

Answer 7

yup,but is us who is making the world end,because we polute with cars,factories,carbon dioxide which comes out of our own mouth,sprays,and way many more stuff,that polutes the ozone ,which is ozone deplation,thats why when we look at the tall builidings you cant see them from far away,its smog wich gets stuck on the ozone,and causes greenhouse effect

Answer 8

THE END IS NEAR
