The bible has very little to say on the topic. The closest would be Genesis 9:11
I establish my covenant with you: Never again will all life be destroyed by the waters of a flood; never again will there be a flood to destroy the earth.
Even that passage has little relevance to the Global Warming issue today, as no one I know would suggest that Global Warming/Climate Change is threatening to cover the entire Earth with water.
I believe the larger question here is whether or not you believe that God directs history. If you believe that God is in control of the world, as do most Christians, then Global Warming and it's consequences are irrelevant. Maybe God intends catastrophe, and Global Warming will change the face of the planet; if so, this is God's will and mankind will be powerless to prevent it.On the other hand, maybe God intends it all come to nothing; in this case "Nature" will recover no matter how much mankind pollutes things.
This means that it makes little difference to Christians whether or not Global Warming itself is or is not real, because we have no influence in the outcome either way. The idea that we need to recycle more or become more energy efficient in order to "save the planet" is something that many Christians will vehemently dispute. There may be other good reasons to do both, but from the Christian perspective, saving the planet isn't one of them.
This isn't to say we should always act helpless. If I see a house on fire, I'm going to call the fire department to put it out. But what alarmists are talking about here is on the level of global catastrophe; perhaps not complete utter destruction, but still on the level where Christians tend to believe things are firmly in God's Hands.
That out of the way, there is also a stewardship issue in play here as well: God gave the Earth to mankind, to take care of it. It is amazing to me that Christians who would never just throw litter around will also take part in polluting the planet in just slightly less-direct ways. Of course, I am no doubt just as guilty of this hypocrisy, as are many Global Warming advocates. It's just so easy to cause indirect pollution these days; if you rode a vehicle to work or school this morning that ultimately derives motive power from petroleum or coal, even a hybrid or mass-transit, you're already guilty.
While perhaps many Christians do doubt Global Warming, it's not really Global Warming or Climate Change that the Christian faith would stand against most strongly: it's the fear-mongering that goes along with it. Let's teach our children to care for the planet, but teach them to do it because it's the right thing to do for themselves and for society (and for believers, because it's what God wants us to do), and not because the world will end if we don't.
We can also go a step deeper. It may not be true that man is powerless against global warming. A major theme in the Old Testament is how it shows a cycle of the Israelite Nation: Israel turns from God, God punishes Israel, Israel turns back to God, God rescues Israel from the punishment and restores it. This theme is repeated over and over. If global warming does result in catastrophic climate change, it may be that God is working through a similar process. In a global culture that is increasingly secular, such a calamity could serve to move the hearts of man back towards God, at which point He would restore us.
If this the case, then there is a route we can take that avoids dooms-day scenarios. However, this route does not involve conservation or limiting carbon dioxide. It's through lifting our hearts to God in prayer and praise.
