Can you believe if we were just a meter closer we'd all burn to a crisp?? Crazy. It can't be just chance...

about 120

Oh you...

FTFY

I know right? It's almost like life adapted to the current conditions and even a slight change can throw things out of balance.

How close would earth have to be for jungles to exist at the latitude of Nebraska?

The distance of the Earth with the Sun plays a negligible role.

Ice ages depend of different process.

>The inclinaison of the Earth around its axe which varies all the 41 thousand years
When the Earth is less oblique, the seasons are less marked, thus, the ice that appeared around the poles during the winters doesn't disappear during the summer.

>The orbit of the Earth.
Sometimes the Earth revolves around the Sun in an elliptical orbit, sometimes it's around a perfect circle orbit. Then again, in a circular orbit the seasons are less marked.

>The axial precession
Sometimes according to a regular time, the Earth is at its closest point to the Sun, some other times, they appear when the Earth is at its farthest point to the Sun. This is the case of the Earth today, the seasons are less marked.

Today and since 11 thousand years, we are in the interglacial period of a glacial period. The interglacial period will stand for again 30-40 thousand years if humans don't destroy too much the climate.

Other things can change the climate but it's at a longer scale of time.

For example:
>The alteration of the rocks
Volcanoes liberate CO2, CO2 goes to the clouds, it rains more around the equator and when it rains the CO2 falls, CO2 goes to the oceans, volcanoes liberate CO2 etc
Thus, when continental masses are around the equator, CO2 decreases in the atmosphere, the temperature falls down.

This is what happened 650 million years ago when all continental masses where around the equator, the temperature fell down to about -50°C celsius and all the Earth was recovered of several kilometers of ice on all its surface, this is what we call the "Snowball Earth".

To give you another example, 50 million years ago, India hit Asia and it created the Himalaya. Because the mountains are very high, it blocked the clouds and it rains with the CO2 which was stocked in the clouds. Andes Mountains contributed to the same thing when they rose up 40 million years ago. Thus, 40 million years ago, the temperature decreases of 4°C.

Mountains and the position of continents play a role in the alteration of the rocks.

>Ocean courants
For example, Antarctica was green in the past and when Drake's straight took shape 30 thousand years ago, Antarctica became what we know.

>Ices play a role too
Because the solar rays bounce on it and go back to the space, the more there are ice, the colder the Earth is, it's vicious circle, like the CO2 in the atmosphere, but in the other way.

Sorry for my English.

Other things too

>Volcanoes activity
Volcanoes liberate CO2, when the activity is strong they liberate too much CO2 which stay in the atmosphere and contribute to increase Earth's temperatures like at the time of the dinosaures.

The distance of the Earth around the Sun is really not important.

Move Earth to Mercury's orbit -- tell me how many ice ages you think we'd get.

Move Earth to Pluto's orbit. Tell me how often you think we'd get out of one.
