The fact is fossil fuel carbon will stay in the surface climate system for millennia.

Scientists will say we can't blame global warming for any single event. In a sense that's right, but the fact that the frequency and intensity of these events is increasing you can blame on global warming.

Interference with communications of science to the public has been greater during the current administration than at any time in my career.

It has become very difficult for anyone to argue that observed global warming is natural variability. We have good reason for being able to say that the world will be warmer by about a quarter of a degree in the next decade. It's the same reason we had 10 years ago when we said that the 1990s would be warmer than the 1980s: The planet is out of equilibrium.

The fact is fossil fuel carbon will stay in the surface climate system for millennia.

...99 percent confident that the world really was getting warmer and that there was a high degree of probability that it was due to human-made greenhouse gases.

It would be immoral to leave young people with a climate system spiraling out of control.
