Carbon dioxide isn't the only greenhouse gas out there. Other substances, such as water vapor and nitrous oxide, also trap heat to varying degrees.
The greenhouse effect of carbon-dioxide emissions does produce gentle warming if it is not counteracted by unpredictable natural phenomena, but it cannot be measured directly against the volume of such emissions.
I am not convinced the Clean Air Act was ever intended to regulate or classify as a dangerous pollutant something as basic and ubiquitous in our atmosphere as carbon dioxide.
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 c...
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.
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.
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.
What makes tar sands particularly odious is that the energy you get out in the end, per unit carbon dioxide, is poor. It's equivalent to burning coal in your automobile.
Coal is responsible for as much atmospheric carbon dioxide as other fossil fuels combined and it still has far greater reserves. We must stop using 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 i...
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.
Ocean acidification - the excess carbon dioxide in the atmosphere that is turning the oceans increasingly acid - is a slow but accelerating impact with consequences that will greatly overshadow all the oil spills put together. The warming trend that ...
Centuries-old habitats such as coral gardens are destroyed in an instant by bottom trawls, pulverized by weighted nets into barren plains. And global carbon dioxide emissions from human activity affect the ocean, changing the pH balance of the waters...
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.
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.
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.
We can look back through ice-core data and see over 800,000 years, relationships between carbon dioxide and the temperature of the world. So those people who deny the importance of climate change are just wasting their time. They're also being divers...
Carbon dioxide is unusual because it doesn't go through the usual three phases of matter, from solid to liquid to gas, but it goes straight from solid to gas. The volume of the gas is much greater than the volume of the solid. When a solid turns into...
I drove an electric car for seven years because of its advanced technology, not because I have any concerns about energy resources. I have none at all. And when environmentalists say that global warming is dangerous, unprecedented and that we'll have...
In recent years, America's wealthiest man has begun to tackle energy issues in a major way, investing millions in everything from high-capacity batteries to machines that can scrub carbon dioxide out of the air. With a personal fortune of $50 billion...
It just so happens that the green religion is now taking over from the Christian religion. I don't think people have noticed that, but it's got all the sort of terms that religions use... The greens use guilt. That just shows how religious greens are...
