“The greenhouse crisis is the bill coming due for the Industrial Revolution. It's not an accident. It's the logical outcome of our world view - the idea that we can control the forces of nature, that we can have short-term expedient gains without paying for them, that there are no limits to exploitation of the environment, that we can produce and consume faster than nature's ability to replenish.”

“The models that have been constructed agree that when, as has been predicted, the level of carbon dioxide or its equivalent in other greenhouse gases doubles from pre-Industrial Revolution concentrations, the global average temperature will increase, and that the increase will be 1.5 to 4.5 degrees Celsius or 3 to 8 degrees Fahrenheit... In Dallas, for instance, a doubled level of carbon dioxide and other gases like methane, would increase the number of days a year with temperatures above 100 degrees from 19 to 78 each year.”

“The unthinkable is that we're distorting this atmospheric balance. We're shifting the chemical balance so that we have more poisons in the atmosphere - ozones and acid rain on ground level - while we're also changing the thermal climate of the earth through the greenhouse effect and - get this - simultaneously causing destruction of our primary filter of ultraviolet light. It's incredible. Talk about the national-debt crisis - we're piling up debts in the atmosphere, and the piper will want to be paid.”

“These things are happening in large measure because of us. We in this country burn 25 percent of the world's fossil fuel, create 25 percent of the world's carbon dioxide. It is us - it is the affluent lifestyles that we lead that overwhelmingly contribute to this problem. And to call it a problem is to understate what it really is. Which is a crime. Crime against the poorest and most marginalized people on this planet. We've never figured out, though God knows we've tried, a more effective way to destroy their lives.”

“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.”
