Are we entering a new Ice Age according to Milankovitch cycles?

It thus seems reasonable to say we are entering another Ice Age according to Milankovitch cycles. Some of the Milankovitch conditions would appear to make the Earth ripe for a new glacial epoch ...

What would be the impact on tides if the earth had no tilt?

A simple way to estimate the implications is to simplify the problem. If the orbits of Earth, Sun and Moon were circular and in the same plane, and the Earth had no tilt, the only remaining tidal ...

What would the equilibrium temperature be at the poles in a world without seasonality?

If we consider that by "Assume daily cycle and convection and so on operate as usual" you meant that all heat transport from/to the pole remain as it is today. Then, we can do a back of the envelope ...

Can anyone explain the torque that causes the Earth's axial precession?

Any object with a non-spherical moment of inertia tensor that is subject to a non-uniform gravitational field will experience a torque due to the gradient of the gravitational field. This can result ...

What would happen to the Earth if there were no seasons?

In a short timescale, let's say one or two years after a permanent equinox state, the temperature would be basically the current mean annual temperature. This is because if we take the premise of ...

What would be the impact on tides if the earth had no tilt?

I cannot answer your hypothetical question, but the tilt does probably affect the tides and there have been some studies on the topic. Hopefully they can inspire to further ideas and speculations. It ...

How much is Solar Radiation effected by Axial Tilt or Obliquity?

"Obliquity of the ecliptic for 20,000 years, calculated by Laskar (1986) reflects change from 24.2° to 22.5°. Diagram Until 1983 the obliquity for any date was calculated from work of Newcomb, who ...

How much is Solar Radiation effected by Axial Tilt or Obliquity?

Check out this matlab program that is presented in a paper by Kostadinov and Gilb, 2014. The paper is worth reading, and they have their full matlab code in the "supplement" link (top right corner ...
