Albedo: unitless, from 0 to 1. Higher= more reflective
Hadley circulation: warm air at equator rises, loses water, settles in 30N/S as dry air (deserts are here).
Then it moves back to equator along surface, pickin

Weather is chaotic, which means that it cannot be forecast very far into the future,
but on average it is not chaotic
Climate- some kind of average of the weather, can calculate the expected average

1a. From 1900-2000, there is a decent balance of red and blue anomalies until 2000, when there is more
blue (less snow). From 2015 onwards, there is almost no red visible and the amount of blue grows a
large amount, eventually

1a. Yes, I noticed increased precipitation globally, and especially increased precipitation in non-equator
regions in 2099 compared to 2000.
b. All 3 models (CCSM4, CanESM2, GISS-E2-H) show a small increase in precipitation glo

The model heat flux at the top of the atmosphere is 289 W/m 2, which is lower than the heat flux
calculated at the ground, 457 W/m 2. I found the ground temperature, 299.7 K, with the altitude plot and
then raised it to th

1a. Increasing CO2 degassing drives atmospheric CO2 up.
1b. When increasing the degassing rate from 7.5 to 9, it takes around 800,000 years for CO 2 to settle at
its new concentration of 450ppm.
1c. On the timescale of a mere 1

1a. I got 0.24C/decade.
b. Historical is much better, it was off by .06 whereas the other was off by .18.
2a. The typical change in the arctic is the highest the models show, +10C.
b. Some of the more northern parts of the Nort

1. IR emission from the ground decreases as I move the locality further from the equator and towards
the North Pole. It also is higher in summer than winter, meaning that IR emission has a direct
relationship with temperature.

1a. The peak seems to be pretty definitely around 1970-1975, while the reservoir size is around 27-31

The peak width would be about 40 years, with a

Six Degrees was an especially entertaining book to read after taking this class. I particularly
enjoyed the structure of the book, using each chapter, as an additional degree was a clever idea. When I

weather - chaotic, can't be forecast very far into future
climate - average of weather over a period of time
