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.
The U.S. can become carbon neutral in our lifetimes. In the process, we will put millions of Americans to work, make our companies more competitive, and shield our communities from extreme weather. And we will honor our obligation to leave the world a better place for future generations.
Life exists in the universe only because the carbon atom possesses certain exceptional properties.
The fact is that any carbon legislation is designed to make us not use coal. So if you're a state that has a lot of coal, you're going to get hammered.
The U.S. limits mercury, arsenic, and soot from power plants. Yet, astonishingly, there are no national limits on how much carbon pollution these plants can dump into our atmosphere.
A lot of the bikes are carbon wheels now, and you don't have as good a braking surface on a carbon wheel in the wet weather as you do on the old aluminium rims.
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.
Childfree women are actually great assets to the planet. Our carbon footprint is smaller than a mom's! And we have enough money to write checks to organizations that help kids get vaccinations, vitamins, and educations yet have plenty of free time to advise your daughter that one day she will regret piercing her lip.
In the course of my stay there, I also showed how one could analyse the experimental kinetic curves for the reaction of haemoglobin with carbon dioxide or oxygen by simulations in the computer, and so fit the rate constants.
I'm interested in humor, and greeting cards just happen to be a perfect medium for my message. They're accessible to everyone, and thanks to all the advances that have been made by environmentally conscientious printers, I can get my message across while keeping my carbon footprint relatively small.
Many years ago it was taught that plants and animals were composed of different materials: plants, of a chemical substance of three elements,- carbon, hydrogen, and oxygen; animals of one of four elements, nitrogen being added to the other three.
With 'Little Accidents', I spent probably three months working with a physical therapist, just understanding, starting from square one, about the neurological makeup of what happens when you have a stroke or what carbon monoxide poisoning does to your body.
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.
I don't believe that a hydrogen economy depends on a carbon economy at all.
As a scientist, my attention became totally focused on global warming some 15 years ago by the elegant and powerful measurements of carbon dioxide trapped in ice cores taken as much as 2 miles deep from the great East Antarctica ice sheet.
The reason we should do a carbon tax is because it's the right thing to do. It's economics 101, elementary stuff.
She felt Britain should not be so dependent on coal. She was in favour of building up nuclear energy to break the dependence on coal, and the main opposition to nuclear came from the environment movement. Mrs. Thatcher thought she could trap them with the carbon emissions argument.
You can pregrow a village with no consequence on the land. In fact, with a positive carbon contribution.
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.
Safer chemicals and more energy-efficient technologies can provide cooling without severe climate implications. Shifting to these alternatives could avoid the equivalent of 12 times the current annual carbon pollution of the United States by 2050.
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.
Ocean acidification is caused by the ocean absorbing excess carbon dioxide from the atmosphere, the same carbon dioxide that is the primary cause of global warming, hence the nickname 'the other carbon problem.' As they do so, the oceans become more acidic with terrible consequences.
Just as human activity is upsetting Earth's carbon cycle, our actions are altering the water cycle.
We have always existed in different forms - carbon, oxygen, water, heat. Maybe Heaven is this brief period when the elements realize they're alive.
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.
The simplest way to remove carbon dioxide, the main greenhouse gas, is to grow plants - preferably trees, since they tie up more of the gas in cellulose, meaning it will not return to the air within a season or two. Plants build themselves out of air and water, taking only a tiny fraction of their mass from the soil.
I like my house to be unique to me. Sure, I've bought plenty of things out of a catalog, but the way I put them together in my home is special. You might have bought your sofa at a major home decorating store, but the rug you found at the flea market is so unique, it takes your room from 'carbon copy' to 'simply yours' in no time.
The best way to deal with climate change has been obvious for years: cut greenhouse-gas emissions severely. We haven't done that. In 2010, for example, carbon emissions rose by six per cent - the largest such increase on record.
If you're eating grassland meat, your carbon footprint is light and possibly even negative.
I give thanks for the fact that I can get this stick with a bit of steel nib on the end, dip it in some black carbon stuff, and draw on paper. Now, people did it the same way 2,000 years ago. And there's something lovely about that play, and making mud pies and a mess. That's a lovely privilege.
Though every nation must do its part to address climate change, developed nations are responsible for the lion's share of carbon pollution in the atmosphere, and they have an obligation to help developing nations transition to a sustainable future.
I have been a long-term environmental advocate for the agriculture industry. I have particularly tried to push carbon farming or carbon sequestration.
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.
Humanity has nearly suffocated the globe with carbon dioxide, yet nuclear power plants that produce no such emissions are so mired in objections and obstruction that, despite renewed interest on every continent, it is unlikely another will be built in the United States.
Boron is carbon's neighbor on the periodic table, which means it can do a passable carbon impression and wriggle its way into the matrix of a diamond. But it has one fewer electron, so it can't quite form the same four perfect bonds.
Carbon has this genius of making a chemically stable, two-dimensional, one-atom-thick membrane in a three-dimensional world. And that, I believe, is going to be very important in the future of chemistry and technology in general.
