Obama's science guy admits the sun causes global warming

In a recent article President Obama's science adviser John Holdren said that we might need to consider seeding the atmosphere with pollution to cut the solar gain from the sun, if global warming gets too severe. This, to my mind, admits that the sun is contributing to global warming right now. I have a few questions and commens for Mr.Holdren, and am awaiting his replies:

I heard about the plan to “research” what it would take to cut sunlight and curb warming by shooting pollution into the upper atmosphere, simulating a volcano eruption.

First off, I work in computers and we never do anything to a running system to improve it that we can’t reverse in case we don’t get the results we expect. In this case, please be sure that any such plans you have to tinker with the atmosphere include methods to completely UNDO your changes, should we decide that is advised.

Second, can you tell me of any experiment or project that has attempted to engineer weather or climate in such a scale that has been proven successful?

Third, your analogy of being in a car, heading toward a cliff, without brakes, in the fog is clever: we are headed for disaster, but we lack control of the rate of our movement, and in fact, we don’t even know how far away the disaster is; even if we try steering the car away from the disaster, since we lack visibility we don’t know if we will point ourselves toward or away from the cliff; our actions may actually hasten our demise. Although we can see the earth warming in places, we don’t yet know why it is warming; and in fact doesn’t shooting particles into the atmosphere admit that the SUN is one of the main causes of global warming, not human activity? If the sun is at fault here, it's not getting it's due. Most if not all of the current global warming solutions attempt to control CO2 production. What proportion of global warming is due to the sun?

I look forward to your answers to these questions.
