The atmospheric CO2 concentration is rising - mainly due to the burning of fossil fuels. It's agreed that this build-up will, in itself, induce a long-term warming trend, superimposed on all the other complicated effects that make climate fluctuate.
...it is fairly well agreed that the surface temperature will rise about 1°C as a modest response to a doubling of atmospheric CO2 if the rest of the component processes of the climate system remain independent of this response.
My view is that we don't know what's causing climate change on this planet. And the idea of spending trillions and trillions of dollars to try to reduce CO2 emissions is not the right course for us.
In a well-monitored storage site, it is always possible to release CO2 in a controlled manner in the unlikely event that it threatens to escape. Such a release is certainly no worse than ignoring the emission in the first place.
Organisms dont think of CO2 as a poison. Plants and organisms that make shells, coral, think of it as a building block. — © Janine Benyus

Concentration of greenhouse gases, especially CO2, have increased substantially since the beginning of the industrial revolution. And the National Academy of Sciences indicates that the increase is due in large part to human activity.
People sometimes say we need to be really almost on a wartime footing if you want to change. Our whole economy is based on burning fossil fuels, which is taking CO2 out of the ground and putting it up into the air.
First and foremost, energy efficiency is a major lever for reducing CO2 emissions along all parts of the energy chain - from the production of resources all the way to final consumption.
Climate change is a global issue - from the point of view of the Earth's climate, a molecule of CO2 emitted in Bejing is the same as a molecule emitted in Sydney.
Ventilation is needed to ensure we get air disbursed throughout the Station. Air stagnates without flow, so it is essential to have good ventilation so one doesn't end up in a bubble of CO2 by accident and then not be able to breathe.
Doom yourself to horrific climate change by burning all that carbon and releasing all that CO2. Or power down society, reducing total energy usage around the planet. One leads to ecological collapse. The other is a reversion, in many ways, to poverty.
It's fine if you're making 1,000 or 2,000 of an electric car, and I think there is value in that in a lot of ways, but it's not going to have a big dent in oil consumption in the country, or CO2 emissions.
Changing the world's oceans to increase their uptake of CO2, as other geoengineering solutions propose, is equally dangerous, as the increased resulting acidity of the oceans kills tiny crustaceans, such as krill, that are the basis of the pyramid of life on the planet as we know it.
Every footstep we take, every action has a consequence. We breathe in weather, but we breathe out CO2. We're responsible for weather and for climate.
Does it make more sense to provide air conditioning or to limit CO2 emissions. I vote for more air conditioning in these susceptible regions.
It's important to see things in perspective. Automobile traffic is responsible for only 12 percent of total CO2 emissions. One should be able to point this out without being accused of changing the subject.
We designed a car that is for daily commutes and that you charge every day. The less you use the gasoline engine, the better mpg. Essentially, the Karma can achieve dramatic savings and low CO2 output when used as intended, as a daily commuter.
I thought if the climate was heating that CO2 was the only forcing, and it would be late in the century before we had trouble. Now that we know about the other half of the forcing, it's obvious that the trouble is coming much sooner.
I think that if you don't do the full analysis of what the origin of the electrical power is, where it comes from, how you get batteries into these cars, what the cost is in terms of CO2 and the environment, I think the analysis that we are going to save the planet with electric cars is nonsense.
Almost every way we make electricity today, except for the emerging renewables and nuclear, puts out CO2. And so, what we're going to have to do at a global scale, is create a new system. And so, we need energy miracles.
Just like you could dump oil into the Cuyahoga in the 60s and let someone else foot the bill, today you can pump CO2 into the atmosphere and let the whole world foot the bill.
If you had no new technology, and you powered society as we do today - mostly by fossil fuels - you'd have only two choices: Doom yourself to horrific climate change by burning all that carbon and releasing all that CO2. Or power down society, reducing total energy usage around the planet.
What is the environmental policy of the Republican Party? When I ask that question, I get a blank stare, if I'm president of the United States, we're going to address climate change and CO2 emissions in a business-friendly way.
About fifty million years ago...geological evidence indicates CO2 levels were several thousand ppm, much higher than now. And life flourished abundantly. — © William Happer

There is some CO2-water vapor feedback. But it's not operating on a global scale. The modellers cannot accurately separate water vapour from the effects of clouds and rainfall.
On the environmental front there's concern about global warming and high levels of carbon dioxide, and trees take in CO2 and store carbon.
Breath does, in fact, connect us all in a very literal way. Take a breath now. And as you breathe, think about what is in your breath. There perhaps is the CO2 from the person sitting next-door to you.
The pace of global warming is accelerating and the scale of the impact is devastating. The time for action is limited - we are approaching a tipping point beyond which the opportunity to reverse the damage of CO2 emissions will disappear.
With this information, in light of the increasing human demands on vegetation, it is my personal opinion that capping CO2 emissions or reducing them to some prior level would be akin to 'biting the hand that feeds us.
Local and state governments have outrun the federal government. The EPA has served notice that it will enact a rule requiring CO2 reductions by major emitters in the absence of major legislation. But it's a blunt instrument that is a little more difficult to use than a legislative remedy.
We have an atmosphere that is roughly 21% oxygen. The rest of it is largely nitrogen. There's just enough carbon dioxide (CO2) to drive photosynthesis. That has been, throughout the history of our species, pretty stable. Until recently.
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.
We face the gravest threat that civilization has ever confronted. It's global in nature and requires a global solution. Increased CO2 emissions anywhere, whether from China or the United States or from one of the countries that is burning its forests like Brazil or Indonesia.
I believe that man does have an impact on the climate, that CO2 has an impact on the climate, and we do take that seriously.
Only by advocating 'politically unrealistic' CO2 concentrations can runaway global warming be avoided. But what is politically realistic for humans is whollymunrelated to what is physically realistic for the planet.
By taxing CO2, firms and households would have an incentive to retrofit for the world of the future. The tax would also provide firms with incentives to innovate in ways that reduce energy usage and emissions - giving them a dynamic competitive advantage.
The atmosphere does not fathom whether CO2 comes from U.S. oil or Chinese coal, nor do hurricanes lose force because the Heritage Foundation doesn't believe global warming is a problem. Living systems operate on laws over which we have no say.
We have used the majority of our carbon budget and we are already at dangerous levels of CO2 concentrations, about 400 parts per million. The levels were 250 before industrialization. So the problem is what we have done already and, therefore, what must be undone.
There appears to be a lot of confusion about the biological benefits of elevated CO2 because the popular media typically fails to report them. Doomsday scenarios of global warming are much more dramatic than the good news of global greening.
I am not a global warming sceptic. I accept that rising human-caused CO2 from fossil sources could 'change the climate'. The basic physics is there to support this view. But where is the evidence that the putative change would be large or damaging?
One of the best ways of reducing both CO2 emissions and poverty in the South would be to strengthen the existing, decentralised demographic pattern by keeping villages and small towns alive. This would allow communities to maintain social cohesion and a closer contact with the land.
Beneath the ocean surface, bad things are happening. Increasing CO2 makes ocean water more acid, and that threatens to dissolve the shells of some ocean animals. Ouch, how'd you like to have your shell dissolve?
Prime Minister Cameron says he wants to be the greenest government ever, but the definition of green is immature... I don't deny for a moment that CO2 is a greenhouse gas, but there are so many other factors that affect climate. It is more complicated than the computer models that we are using. What the truth is, nobody knows.
By burning fossil fuels, we are already dumping 30 billion tons of CO2 into the atmosphere every year, which has a profound effect on the climate. So, like it or not, we're already messing with a system we don't understand.
I don't think you have a choice but to pull CO2 back that has already made it out, or is about to make it out, because we are not overnight shutting down all the coal plants. — © Klaus Lackner

We don't know what's causing climate change on this planet. And the idea of spending trillions and trillions of dollars to try to reduce CO2 emissions is not the right course for us.
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.
Global warming alarmists invariably try to make their case by resorting to rhetoric, dogma, opinion, and emotion. The closest thing to scientific data in their articles is the occasional chart claiming a poorly understood correlation between atmospheric CO2 and the Earth's temperature.
You can measure the warming oceans with a thermometer. You measure sea level rise with a yardstick. You can measure the dramatic increase in acidification with a simple pH test, and you can replicate what excess CO2 does to seawater in a basic high school science lab.
The scientists who do climate research understand that much of the ever increasing concentration of CO2 in the atmosphere since 1850 must be attributed to burning those fossil fuels to produce the energy that drives industrialization.
A worldwide shift to a shorter working week could cut the CO2 emitted this century by half. Countries with a shorter working week have a smaller ecological footprint.
NASA's Aqua satellite is showing that water vapor, the dominant greenhouse gas, works to offset the effect of carbon dioxide - CO2. This information, contrary to the assumption used in all the warming models, is ignored by global warming alarmists.
It looks as though yields of over 10 times what we can currently grow per acre are feasible if you control the CO2 concentration, the humidity, the temperature, all the various factors that plants depend on to grow rapidly.
Sunspots and cosmic rays have a 79 percent correlation with our thermometer record since 1860. Meanwhile the CO2 correlation is a mere 22 percent.
I am not at all convinced that human emissions of CO2 are adding to global warming.... I remain to be convinced about the theory of anthropogenic global warming.
Investigations during the last few decades have brought hydrogen instead of carbon, and instead of CO2 water, the mother of all life, into the foreground.
We have fans that circulate air in the cabin of the module of the space shuttle. They're running all the time. They're absolutely necessary because, otherwise, you will breathe your own CO2 and intoxicate yourself quite fast.
The home is the planet. Unless you're a Martian, you know, we're sharing the planet. And - and the emissions don't stop and CO2 doesn't stop with the border between France, Spain or between Canada and the United States.

We thus find ourselves in the situation that the entire theory of man-made global warming-with its repercussions in science, and its important consequences for politics and the global economy-is based on ice core studies that provided a false picture of the atmospheric CO2 levels.
