Does increases in global mean temperatures increase CO2? And if so, how?

No the co2 causes the heat rising to take place.

Warmer oceans can absorb less CO2. There is also a release of gasses included CO2 and methane from the permafrost. Rapid temperature raise will cause some deforestation and desertification, which reduces carbon capture by trees and plants. There are other more complex effects as well.

Yes. Cold water can hold more CO2 than warm water and far more of the earth's CO2 is in the oceans than is in the air.
So, as the climate warms the oceans they emit CO2 which then moves into the atmosphere.

In the sense that warmer water holds less CO2 than cold water, yes
also, thawing permafrost will release methane - CH4 - which is an even more potent greenhouse-gas

CO2 level increase and decrease are a RESULT of global temperature, which of course is moderated by the Earth's only energy source the SUN.
The alarmists like to ignore the Vostok/Greenland scientific ice core research which shows that CO2 level LAG, global temperature increases up to 800 years.
The Medieval Warm period, which occurred from 950 to 1350 and was warmer than the modern solar grand minimum cycle (1980 - 2003) is responsible for the recent rise in global CO2 levels.
The Sun, Galactic Cosmic Ray flux, solar and planetary orbital variances and Nature are the true drivers of the Earth's climate. The AGW is a myth and CO2 is plant food.
Update: Darwin's answer in which he references Henry's Law is a typical alarmist response, where he forget to include pertinent information. Henry's Law by his own reference indicates that "atmospheric pressure" is the determining factor, which he forgets to mention.

It does not. However, many believe the increase in the concentration of carbon dioxide retains heat and therefore causes an average temp increase - hence they believe reducing carbon dioxide production will halt the global warming. However they fail to take into account that we have been, and continue exiting from an ice age which has been going on for well over 50,000 years - and at one time all of what is Western Europe today was ice covered - much ice exceeding 1 mile in thickness. You cannot be exiting an ice age and have the average annual temperature decrease. They also tend to dismiss NASA's 125 year projection for average temperature to drop by over 1.5° due to lesser solar flare activity.

In the past, when the source of the additional CO2 was from the oceans, atmospheric CO2 did rise in response to a temperature increase.
This time, the source is not the oceans, but from underground in the form of fossil fuels, which create CO2 when they are burnt. The oceans are actually absorbing some of this extra CO2, so cannot be the source this time.
Basically, what's going on is that the oceans respond to what is known as Henry's Law.

It's the other way around. More CO2 in the atmosphere traps more heat from the sun. This is called 'the greenhouse effect'.
