Billions of years of climate change

President Barack Obama said in the 2014 SOTU:
Taken together, our energy policy is creating jobs and leading to a cleaner, safer planet. Over the past eight years, the United States has reduced our total carbon pollution more than any other nation on Earth. But we have to act with more urgency – because a changing climate is already harming western communities struggling with drought, and coastal cities dealing with floods. That’s why I directed my administration to work with states, utilities, and others to set new standards on the amount of carbon pollution our power plants are allowed to dump into the air. The shift to a cleaner energy economy won’t happen overnight, and it will require tough choices along the way. But the debate is settled. Climate change is a fact. And when our children’s children look us in the eye and ask if we did all we could to leave them a safer, more stable world, with new sources of energy, I want us to be able to say yes, we did.
The fact is that the Earth's climate has been changing for billions of years. Obama sounds scientifically illiterate when he says "Climate change is a fact.", as if that were the meaningful outcome of a scientific debate.

He is like those who define evolution as change in the history of the universe, or generational variation in DNA, then proudly assert that evolution is a fact.

The speech had nothing about nuclear power, the only practical carbon-free large-scale power technology.

If our children's children complain about atmospheric carbon, they will ask why we encouraged China and India to develop fossil fuel based economies. Those are the countries that are increasing their carbon emissions.
