As co-founder of the Senate Climate Solutions Caucus, I know we need to promote vehicles that reduce our carbon footprint, but it doesn't need to be in the form of tax breaks for the wealthy and their luxury vehicles.
If coal is going to be used, the only response - because it is the dirtiest of all fuels - is that we have to learn how to do carbon capture and storage and we have to learn how to do it quickly on a commercial scale.
I think global warming is the gravest threat. With global warming, it's the product of a war between old energy - between the carbon cronies, who, by the way, could not stay in business in a true free market capitalism.
Not only will a carbon fee reduce carbon emissions, it will force big polluters to pay for the damage their pollution does to public health and the environment, generating billions in new revenue for the American people.
Carbon is the stuff of life, and it's the stuff of everything used by human society. All of our materials are made of carbon or of substances, such as steel or glass, which are produced through the utilization of carbon.
There are many theories about the best way to remove excess carbon from the atmosphere - some are ludicrous, others are at least worth study. The most commonly discussed plan is to lace the sky with reflective chemicals.
Smart cities are those who manage their resources efficiently. Traffic, public services and disaster response should be operated intelligently in order to minimize costs, reduce carbon emissions and increase performance.
To achieve policy stability and certainty, we need to establish a meaningful price on carbon and cut the billions of dollars spent each year on fossil-fuel subsidies, along with well-structured financial tools and rules.
As you get older, whatever your struggles may be - how you sound, how you look, how you dress - you grow into yourself a little bit more. You end up realizing the world wants you and not a carbon copy of six other people.
If the world is to avoid a collision with nature - one that humanity surely cannot win - we must act boldly on every front, particularly with respect to carbon pricing and the coherence of our economic and energy policies.
I do not believe we can effectively move Australia to a lower emission economy, which is what we need to do if we're going to make a contribution to a global reduction in greenhouse gases, without putting a price on carbon.
For the first time in long time, I can say I love what I do. I can't say that every day is easy or fun, but there are few greater thrills in life than hurling yourself down an iced-over water slide in a carbon fiber bathtub.
Cows and other ruminants are worse polluters than all of the transportation in the world, so all of us who try to cut down our carbon footprint by lessening our transportation would do far better by just consuming less beef.
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.
On a submicro scale, pure diamond is billions of billions of carbon atoms bonded to one another. If you shrunk yourself down and stood inside the diamond, you'd see nothing but carbon in a perfect pattern in every direction.
The cap-and-trade plan is more market driven than anything else. If you want to discourage carbon use, you have to make it more expensive, but what is crucial is that this be a worldwide program that includes China and India.
Enlightened self-interest from those involved in hydrocarbons should lead to the support of technologies enabling the clean use of hydrocarbons, such as carbon capture and storage, and not to the defence of deniers and cranks.
We're becoming a planet of a thousand new major cities. The economy of the 21st century is a city-building economy. It's within our power to make it a carbon zero one, too; and to be blunt, civilization depends on our success.
Norway has had a carbon tax in place for a long time. This has not slowed down industrial development. Rather, it has encouraged innovation and the development of solutions that reduce emissions and bring down operating costs.
I think we need to price carbon; there's no question about it. The way we do it needs to be based on science and not political debates and attacks, and that's why I'm drawing on experts and best practices from around the world.
If Britain was to close down altogether overnight, then China would take up the slack of carbon emissions in two years. If America closed down, just the growth in China's emissions would replace America's emissions in 12 years.
The promise of energy savings, reduced carbon emissions and affordable lighting was there from the inception. The proliferation of the technology into areas such as displays, automotive, medicine and horticulture was unexpected.
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.
There is no question that global warming will have a significant impact on already existing problems such as malaria, malnutrition, and water shortages. But this doesn't mean the best way to solve them is to cut carbon emissions.
Artificial lighting, air-conditioning, and automobiles, all powered by fossil fuels, swaddle us in our giddy modernity. In our ergonomic chairs and acoustical-panel cubicles, we sit cozy as kings atop 300 years of flaming carbon.
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.
Climate change is real. Climate change is being substantially increased by humans and the carbon we put into the atmosphere. And it appears to be speeding up. If science has made any mistakes, science has been underestimating it.
The challenge of global warming should stimulate a whole raft of manifestly benign innovations - for conserving energy and generating it by 'clean' means (biofuels, innovative renewables, carbon sequestration, and nuclear fusion).
What you do by having an income tax rate reduction across the board, you really provide great incentives for people to work, produce, and increase output. So I would support a carbon tax in replacement for a progressive income tax.
The fact that companies are getting into building power plants that collect their own CO2 on-site shows there's some leadership in that industry. Some industries have seen the writing on the wall: that carbon will have to be managed.
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.
It seems like every week we are considering bills that would make it harder to limit the amount of carbon we are dumping into our atmosphere, and prevent implementation of clean technologies. The voters who sent us here deserve better.
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.
I was recently looking at what they can actually do to reduce consumption of petrol. It would be quite possible to build automobiles out of carbon fibre that would be just as strong, weigh 10 times less and consume 10 times less petrol.
A majority of American citizens are now becoming skeptical of the claim that our carbon footprints, resulting from our use of fossil fuels, are going to lead to climatic calamities. But governments are not yet listening to the citizens.
If every country committed to spending 0.05 per cent of GDP on researching non-carbon-emitting energy technologies, that would cost $25 billion a year, and it would do a lot more than massive carbon cuts to fight warming and save lives.
Every fish fertilizes the water in a way that generates the plankton that ultimately leads back into the food chain, but also yields oxygen, grabs carbon - it's a part of what makes the ocean function and what makes the planet function.
We have to ensure politically that what's doable can indeed by translated into law, but what's not doable mustn't become European law. Otherwise, the auto industry will work somewhere with higher carbon emissions - and we can't want that.
We need to go to net zero carbon really quickly. And we're also asking for a people's assembly so people can decide how the change happens. We'll know when governments are doing different things, it could feel like a war, a beautiful war.
There is simply no defending the preferred mode of travel for many of the celebrity crazies who lecture us about carbon credits. Do you think these folks are willing to give up their mansions and private jets in order to 'save the planet?'
One of the most obvious reasons to start using timber rather than concrete is that it's the one commonly grown and therefore exceptionally renewable building material that we have available to us. And it acts as storage for carbon dioxide.
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.
Alongside energy efficiency, renewables and abatement, I believe safe nuclear power, with manageable waste, can play an important role in reducing greenhouse gas emissions, as long as it is cost competitive with other low carbon generation.
Even as our unwitting alterations to Earth's carbon and hydrological cycles slowly make storms more damaging, our ability to monitor our planet from space and make reliable short-term forecasts have equipped us enormously to withstand them.
Some solutions are relatively simple and would provide economic benefits: implementing measures to conserve energy, putting a price on carbon through taxes and cap-and-trade and shifting from fossil fuels to clean and renewable energy sources.
I pattern my actions and life after what I want. No two people are alike. You might admire attributes in others, but use these only as a guide in improving yourself in your own unique way. I don't go for carbon copies. Individualism is sacred!
We are already witnessing a transformation in the U.S. economy to increased production of lower carbon energy through fuel switching to natural gas and expansion of wind, solar, geothermal, and other renewable non-carbon intensive energy sources.
A factory that can turn carbon nanotubes into a sheet a yard wide and long enough to stretch one-fourth of the way to the moon is not something you'll find at your local industrial park. That's the show-stopper for the space elevator. The ribbon.
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.
I agree with the overwhelming majority of scientists who recognize that climate change is real, and it's essential that our country honors its commitment to work with the rest of the world to cut carbon pollution and address this crisis together.
