Not soon enough and at the scale that we need to address the problem. Keep in mind the ability to adopt electric cars and go home solar is still a very privileged position and will be for quite a while. Think about how many cars that are 10 or 20 years old on the road now. Or how many people live in apartments. And this is just in the developed world.

This is why most climate scientists advocate for at least a tax on all carbon. While the free market might be able to solve this world-wide on a long enough time scale we don't have the time for that to play out. We've been building our current energy and transportation infrastructure out for the past century globally based on fossil fuels.

To get a good idea on the scope of the problem I'd highly recommend start reading through some of the forum below. Some of the brightest (to me anyway :)) experts on the climate post regularly here.
