Climate change science -- how settled?

As I understand it, some of the science of climate change is settled (as 
far as science can ever really be settled) and some of it is not.

Settled: Global average surface temperature has been rising since the 
end of the Little Ice Age in the nineteenth century.

Not settled: Whether and to what degree human activity is affecting the 
warming trend.

Not settled: How high average surface temperature is likely to rise and 
how long the warming trend will continue.

Settled: Earth's climate is always changing, warmer or cooler.

Settled: None of the current proposals for addressing climate change 
will affect the global warming trend, but will transfer wealth and power 
to climate "scientists", government bureacracies, and energy companies 
at the expense of the living standards of the middle- and lower-classes 
around the world.
