The Arctic is a place that historically, during all preceding human history, has largely been an icy realm with an impact on ocean currents. That, in turn, influences the temperature of the planet. The Arctic is now vulnerable because of the excess carbon dioxide in the atmosphere, with a rate of melting that is stunning.

Now, we put out a lot of carbon dioxide every year, over 26 billion tons. For each American, it's about 20 tons. For people in poor countries, it's less than one ton. It's an average of about five tons for everyone on the planet. And, somehow, we have to make changes that will bring that down to zero.

I remember, as a boy of 17 years of age, this was a fascinating thing for me: how we human beings breathe out carbon dioxide into the air, the leaves of plants pick this carbon dioxide up, and the plant gives off oxygen, which we can breathe in and keep our life going.

Elon Musk

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.

Climate change is not just about carbon dioxide levels and melting polar ice caps. It is about our public health and protecting our Earth for future generations.

American Politician

Sam Brownback

I support strongly the expansion of nuclear power because that is one of the key ways of getting electricity generated and reducing carbon dioxide emissions.

Andrew R. Wheeler

America is a global leader on clean air progress and carbon dioxide reductions, and we are the envy of the world when it comes to clean water.

There are several types of greenhouse gasses, but carbon dioxide is the most important.

American Journalist

Michele Bachmann

Carbon dioxide is natural. It is not harmful. It is part of Earth's life cycle.

John Barrasso

Humans are contributing to additional carbon dioxide in the atmosphere.

Dioxide compounds consist of two oxygen atoms bonded to another element, like carbon or sulfur.

Chemical Composition

Dioxides, especially carbon dioxide, are important in discussions about climate change and air quality.

Environmental Relevance

The word 'dioxide' is often used in scientific and technical fields, like chemistry and environmental science.

 that might be happening deep beneath our feet. Fracking's biggest controversy, though, is happening above the ground. The general consensus is that burning natural gas is better for the environment than burning coal since the gas collected from fracking emits only half the carbon dioxide as coal

 And each of these looks like a hydrogen bomb; actually, the effects are even worse. This is when deep-Earth material comes to the surface, spreads out over the surface of the planet. Well, it's not the lava that kills anything, it's the carbon dioxide that comes out with it.
