If we drive our fellow species to extinction, we will leave a far more desolate planet for our descendants than the world we inherited from our elders.
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.
...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.
We cannot afford to put off change any longer. We have to get on a new path within this new administration. We have only four years left for Obama to set an example to the rest of the world. America must take the lead.

I think I was just trying to find my father, ... I hadn't been able to ask him these questions.
I think this is a more optimistic assessment of the chances for keeping climate change moderate in the next 50 years, and the way to do that is to focus on stopping the growth of several gases, ... Global Warming in the 21st Century: An Alternative Scenario.

We've driven them out of the range that has existed for the last 1 million years. And the climate has not fully responded to changes that have already occurred.
