PALIN: Yes. Well, as the nation's only Arctic state and being the governor of that state, Alaska feels and sees impacts of climate change more so than any other state. And we know that it's real.
I'm not one to attribute every man -- activity of man to the changes in the climate. There is something to be said also for man's activities, but also for the cyclical temperature changes on our planet.
But there are real changes going on in our climate. And I don't want to argue about the causes. What I want to argue about is, how are we going to get there to positively affect the impacts?
We have got to clean up this planet. We have got to encourage other nations also to come along with us with the impacts of climate change, what we can do about that.
As governor, I was the first governor to form a climate change sub-cabinet to start dealing with the impacts. We've got to reduce emissions. John McCain is right there with an "all of the above" approach to deal with climate change impacts.
We've got to become energy independent for that reason. Also as we rely more and more on other countries that don't care as much about the climate as we do, we're allowing them to produce and to emit and even pollute more than America would ever stand for.
So even in dealing with climate change, it's all the more reason that we have an "all of the above" approach, tapping into alternative sources of energy and conserving fuel, conserving our petroleum products and our hydrocarbons so that we can clean up this planet and deal with climate change.
IFILL: Senator, what is true and what is false about the causes?
BIDEN: Well, I think it is manmade. I think it's clearly manmade. And, look, this probably explains the biggest fundamental difference between John McCain and Barack Obama and Sarah Palin and Joe Biden -- Gov. Palin and Joe Biden.
If you don't understand what the cause is, it's virtually impossible to come up with a solution. We know what the cause is. The cause is manmade. That's the cause. That's why the polar icecap is melting.
Now, let's look at the facts. We have 3 percent of the world's oil reserves. We consume 25 percent of the oil in the world. John McCain has voted 20 times in the last decade-and-a-half against funding alternative energy sources, clean energy sources, wind, solar, biofuels.
The way in which we can stop the greenhouse gases from emitting. We believe -- Barack Obama believes by investing in clean coal and safe nuclear, we can not only create jobs in wind and solar here in the United States, we can export it.
China is building one to three new coal-fired plants burning dirty coal per week. It's polluting not only the atmosphere but the West Coast of the United States. We should export the technology by investing in clean coal technology.
We should be creating jobs. John McCain has voted 20 times against funding alternative energy sources and thinks, I guess, the only answer is drill, drill, drill. Drill we must, but it will take 10 years for one drop of oil to come out of any of the wells that are going to begun to be drilled.
In the meantime, we're all going to be in real trouble.
