Burning fossil fuels emits carbon dioxide. And carbon dioxide is a greenhouse gas that traps heat in the atmosphere. There is no debate about that. The link is as certain as the link between smoking and cancer.

On the environmental front there's concern about global warming and high levels of carbon dioxide, and trees take in CO2 and store carbon.

Senator Hillary Clinton is attacking President Bush for breaking his campaign promise to cut carbon dioxide emissions, saying a promise made, a promise broken. And then out of habit, she demanded that Bush spend the night on the couch.

Organisms in the ocean provide over 40 percent of the oxygen we breathe, and they're the major sink for capturing all the carbon dioxide we constantly release into the atmosphere.

Solving climate change is a complex topic, but in a single crude brush-stroke, here is the solution: the price of carbon dioxide must be such that people stop burning coal without capture.

The majority of America wants action on climate change. The majority of America thinks we should regulate carbon dioxide as a pollutant. And the majority of America thinks we should prioritize solar and wind infrastructure over fossil fuels. Those are impressive majorities, ones that every office seeker and office holder should heed.

We're running the most dangerous experiment in history right now, which is to see how much carbon dioxide the atmosphere... can handle before there is an environmental catastrophe.

There is universal consensus among experts that the earth's atmosphere is heating up - and that we are responsible for it by putting carbon dioxide in the atmosphere. We also know that the consequences of global warming are catastrophic. But how do we make sure that all countries reduce greenhouse gases?

Healthy forests and wetlands stand sentry against the dangers of climate change, absorbing carbon dioxide from the atmosphere and locking it away in plants, root systems and soil.

Places that have become agricultural deserts, trashed by giant corporations, could be reforested, drawing carbon dioxide from the air on a vast scale. The ecosystems of land and sea could recover, not just in pockets but across great tracts of the planet.
