Photosynthetic organisms in the sea yield most of the oxygen in the atmosphere, take up and store vast amounts of carbon dioxide, shape planetary chemistry, and hold the planet steady.
Our leaders must get to grips with the huge risk that carbon dioxide emissions pose to the economy and the environment. As we know, carbon dioxide is a long-lived gas. It hangs around.
The toxic effect of carbon monoxide on man has nothing to do with inhibition of cellular respiration by carbon monoxide but is based on the reaction of carbon monoxide with blood iron.
Ultimately, I do want us to be a transformative government. I want, when we've left, for people to say we're not just clean-green anymore: we're carbon neutral, or we're striving to be.
At Virgin, we have always backed the power of the entrepreneur and inventor to find solutions to tricky problems. Why should climate change and the battle against carbon be any different?
Climate change might be disastrous, but does that mean we want carbon taxes that raise the price of a gallon of heating oil to $10? And how exactly will those taxes affect economic growth?
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.
Tar sands oil is the dirtiest fuel on Earth. Because producing it consumes so much energy, a gallon of tar sands crude generates 17 percent more carbon pollution than conventional crude oil.
There are some really wealthy hedge fund billionaires in San Francisco who have pledged a lot of money for Democratic candidates to argue for cap and trade and carbon tax and all these things.
I've been to Vulcan where I've been vulcanized, Carbon where you get carbonated and Standard where you get standardized. Ernie Isley's invited me to Castor … and I'm not looking forward to it.
We need robust sustainability regulations for shipping that are internationally recognised and respected. This will ensure shipping plays its part in the global transition to carbon neutrality.
Money spent on carbon cuts is money we can't use for effective investments in food aid, micronutrients, HIV/AIDS prevention, health and education infrastructure, and clean water and sanitation.
In the course of the 1920s and 1930s, great progress was made in the study of the intermediary reactions by which sugar is anaerobically fermented to lactic acid or to ethanol and carbon dioxide.
Julianne Moore and Michael Keaton began in 1980s soap operas and 1970s sitcoms, respectively, such ancient history by show business standards that you need carbon dating to measure their careers.
We have to slow down the emissions of carbon dioxide and methane from coal burning, oil and eventually natural gas... And the best ways to do that are energy efficiency and a switch to renewables.
We can halt the destruction of the world's rainforests - and even restore parts of them - in order to ensure that the forests do what they are so good at - in other words, storing carbon naturally.
The U.S. has a proud history of cleaning up our air through technological innovation. We did it with leaded gas, acid rain and countless other pollutants, and we can do it with carbon pollution, too.
In corn, I think I've found the key to the American food chain. If you look at a fast-food meal, a McDonald's meal, virtually all the carbon in it - and what we eat is mostly carbon - comes from corn.
As Speaker, I passed Maine's most aggressive carbon emission reduction and renewable energy standards, and in the Senate, I will prioritize moving toward a completely clean and renewable energy system.
We're not just any star stuff, most of which is humdrum hydrogen and listless helium. Our bodies include fancier ingredients like carbon, oxygen, nitrogen, phosphorous, and a few other herbs and spices.
Is the raggle-taggle Brangelina tribe any more bogus than that of the landlocked yummy mummy who believes that she can drop half a dozen brats and still keep a modest carbon footprint? I don't think so.
It's a really big deal to do a spacewalk. It's much riskier than staying indoors. It's complex. It uses up a lot of the precious resources onboard. It uses up oxygen. It uses up carbon dioxide scrubbers.
Many have criticized a federal carbon tax, saying that it would increase energy costs. Some continue to oppose it even when that revenue would be used to reduce other taxes in what's known as a tax swap.
The key players are now all in place in Washington and in state governments across America to officially label carbon dioxide as a pollutant and enact laws that tax us citizens for our carbon footprints.
As with any difficult challenge that the public and policymakers face, there is no single solution or silver bullet that will serve as the answer to how the United States works to reduce carbon emissions.
The more the relationships of the nitrogen-rich substances to the cell nucleus were recognized, the more the question of the arrangement of the nitrogen and carbon atoms in the molecule came to stand out.
I was really overwhelmed by the amount of roles that I got offered that were carbon copies of what I did in 'Up in the Air.' I got every offer for every ambitious, unfeeling practically robotic character.
On a per capita basis, Britain is responsible for more of the carbon dioxide now in the atmosphere than any other nation on Earth because it has been burning it from the dawn of the Industrial Revolution.
Why, for example, should a group of simple, stable compounds of carbon, hydrogen, oxygen and nitrogen struggle for billions of years to organise themselves into a professor of chemistry? What's the motive?
You will die but the carbon will not; its career does not end with you. It will return to the soil, and there a plant may take it up again in time, sending it once more on a cycle of plant and animal life.
By stopping flying, you don't only reduce your own carbon footprint but also that sends a signal to other people around you that the climate crisis is a real thing and that helps push a political movement.
The European auto industry made a commitment to reduce carbon dioxide emissions by an average of 140 grams per kilometer. But then there was a significant change in what customers wanted in their vehicles.
The whole action around a carbon pricing mechanism, or carbon tax, is what you do with the money. Both France and Washington state proposed solving climate on the backs of workers. And that's a bad strategy.
There are some that feel like human activity is the cause for carbon emissions, and because of that, we need to revert to where we were in the 1870s for carbon emissions. I just choose to disagree with that.
The war on driving includes calls for carbon and gas taxes, tens of billions of gas tax money diverted to inefficient and little-used mass transit projects, and opposition to building new roads and highways.
If we moved from industrialized agriculture to re-localized organic agriculture, we could sequester about one quarter of the carbon moving into the air and destroying our glaciers, oceans, forests and lands.
When you have energy companies like Shell and British Petroleum, both of which are perhaps represented in this room, saying there is a problem with excess carbon dioxide emission, I think we ought to listen.
Prominent scientists have become increasingly convinced that the connection between carbon emissions and rising temperatures is real, but skeptics have whole truckloads of studies to demonstrate the opposite.
Australia has suffered a decade of drought, epic floods, a Category 5 cyclone, and a plague of locusts. But just because Aussies have the biggest carbon footprint in the world, it doesn't mean they're stupid.
Cities might become biological entities, walls hung with curtains of algae that glow at night and sequester carbon, and floors made from tweaked cellular material that strengthens like bones as we walk on it.
In organic chemistry, we have learnt to derive from compounds containing only carbon and hydrogen, i.e. from the hydrocarbons, all other types of combinations, such as alcohols, aldehydes, ketones, acids, etc.
Make no mistake: Tackling climate change is vital. But to see everything through the lens of short-term CO2 reductions, letting our obsession with carbon blind us to the bigger picture, is to court catastrophe.
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.
The American Republican Party is the last political bastion of the fossil fuel industry - now so in tow to the fossil fuel industry that it cannot face up to the realities of carbon pollution and climate change.
When you look at the social cost of carbon - and there is a lot of ambiguity around that - what you also need to be doing is looking at the benefits of carbon and what that has on increased agriculture production.
I opposed bad policies like any responsible citizen and business can. The carbon tax and the mining tax were both bad policies that, combined, worked to make Australia more over-regulated and less cost competitive.
Chinese emissions are a problem not just for its own people but also for the world. It has now overtaken the U.S. as the biggest carbon emitter; most of the coal that is burned anywhere on Earth is burned in China.
There is no doubt that we should take solar radiation into account. We have seen ground temperatures rising since 1975, and it is important to know to what extent that has been caused by the sun or by carbon dioxide.
As governor of Washington, I've seen firsthand what's possible when you invest in clean energy - reducing carbon pollution and supporting family-wage jobs that are growing twice as fast as those in any other industry.
I love driving. I still drive a 1993 Toyota Camry. I do want to get an electric car, but it's less of a carbon footprint if you keep your old, fuel-efficient car on the road than if you say 'build me a whole new car.'
