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.
Bill McKibbenThere's no huge mystery. If you dig up huge amounts of carbon, huge amounts of ancient biology, hundreds of millions of year's worth of ancient biology, and flush it into the atmosphere in a matter of decades, then it stands to reason that we're going to have enormous effects, and now we can see those effects all around us.
Bill McKibbenIn the last two years 24 countries have set new all-time temperature records. We've seen flooding on an epic scale in every continent .
Bill McKibbenPat Robertson had decided that global warming was real and we need to do something about it struck me as powerful evidence that the Holy Spirit is hard at work in this question.
Bill McKibbenClimate change is a huge problem, an almost insoluble problem, for two reasons. One is the habits of the West in terms of consumption. The other is the incredible iniquity between poor countries and rich countries on this planet.
Bill McKibbenAll the things that we've done as a species have had a limited scope. We're talking about melting the ice caps, raising the level of the seas dramatically, changing the distribution of every other species on Earth, perhaps wiping out one-third or half of them. The changes at work are geologic in scale. The level of change required to deal with it is enormous, too. It will require change in every country. It will require a degree of global cooperation that we haven't seen before.
