Computer simulation to show the effects of albedo using white and black daisies. It starts off with the sun luminosity being too low for the theoretical planet to support life. As it heats up, black daisies begin to germinate and heat up the planet. It then is warm enough for white daisies to appear, which cool down the planet. Temp is a constant when the white & black daisies are at equilibrium. As the luminosity increases, it gets too hot for black daisies, so they die. White daisies continue to survive until the planet heats up too much from increasing luminosity, and then the land becomes completely barren.
There is also no latitude, longitude, or topographic effects. Your Turn!

What are some possible causes for the Little Ice Age and when did this occur?

Hmm, I guess I'll just answer.
It was from 1350 to about 1850. People speculate it may have been caused by a bunch of volcanic eruptions which could have released volcanic particles and acted like aerosols, creating clouds that scatter the incoming sunlight, decreasing the amount of radiation reaching earth. And also, there was a time of little solar activity in the middle (Maunder Minimum, I believe) which could have contributed to it.

The sea ice albedo feedback loop is a constant loop of surface temperature, sea ice and snowpack, and albedo. For example , if there is more snow and ice pack on the ground, the higher the albedo.

Obliquity, eccentricity, and precession are Milankovitch cycles. Obliquity is the axial tilt of Earth, varying from 22.1 to 24.5 degrees. Eccentricity is how 'circular' Earth's orbit is. Precession is Earth's axis rotation relative to fixed stars. They all vary over periods of thousands of years and result in long-term climate variation.
