Q. Is this evidence of CO2-induced global warming?

It's highly probably that CO2 has contributed to that.

Q. Is it good science to conclude humans are the cause?

A. It's not settled, it's not certain. Anybody who says something this complex is settled is not using good science.

Q. Is current energy policy too focused on fighting carbon emissions?

A. The present policies of subsidizing and mandating inefficient alternatives is counterproductive. The enormous cost and unreliability of wind and solar are making people's lives worse. They're increasing the cost of energy, they're corrupting the business community, increasing corporate welfare, and they're counterproductive. On the other hand, if people believe this is a problem, or could be a problem, then it's worth investing a certain amount in, not by government mandating, but by letting companies like ours and others innovate to find economic solutions that will make peoples' lives better today and in the future. Because there are economic alternatives to fossil fuels and because they reduce whatever risk there is that CO2 emissions can cause real harm in the future.
