CO2 is a pollutant? Tell that to the plants.— Rick Santorum
Bashful Co2 quotations
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.
There are many direct biological benefits that result from higher atmospheric CO2 concentrations. Two of the most important are increased plant photosynthesis and water-use efficiency.
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.
CO2 is so beneficial...it would be crazy to try to reduce it
Even if producing CO2 was good for the environment, given that we're going to run out of hydrocarbons, we need to find some sustainable means of operating.
The warming we've experienced in the late 20th century could just as easily be explained by small decreases in cloud cover - natural changes in the system - and have nothing to do with CO2.
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.
If you really could take the CO2, when you burn hydrocarbons - coal, for example - if you could really capture the carbon and sequester it - they call it CCS - if the extra capital cost, energy cost, and storage costs over time didn't make it super expensive, then that's another path that you could go down.
Changes in clouds and rainfall can overwhelm what little effect CO2-water vapour has on temperature.
No chemical compound in the atmosphere has a worse reputation than CO2, thanks to the single-minded demonization of this natural and essential atmospheric gas by advocates of government control and energy production. The incredible list of supposed horrors that increasing carbon dioxide will bring the world is pure belief disguised as science.
The nuclear approach I'm involved in is called a traveling-wave reactor, which uses waste uranium for fuel. There's a lot of things that have to go right for that dream to come true - many decades of building demo plants, proving the economics are right. But if it does, you could have cheaper energy with no CO2 emissions.
You're never going to get the amount of CO2 emitted to go down unless you deal with the one magic metric, which is CO2 per kilowatt-hour.
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.
The climate system is constantly readjusting naturally in a large way - more than we would ever see from CO2. The CO2 kick [impact of CO2 emissions] is extremely small compared to what is happening in a natural way. Within the framework of a proper study of the sun-climate connection, you don't need CO2 to explain anything.
I think all countries need to aim to cut the CO2 emissions per person, taking account of externalities like imports and exports.
Even if you accept the theory of man-made climate change, wind turbines are a rotten way to reduce CO2 emissions, or to improve energy security.
CO2 emissions have been increasing, but the rise in air temperature stopped around 2001. Climate change is due in large part to naturally occurring oscillations.
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.
The main thing that's missing in energy is an incentive to create things that are zero-CO2-emitting and that have the right scale and reliability characteristics.
It's not as though we can keep burning coal in our power plants.
Coal is a finite resource, too. We must find alternatives, and it's a better idea to find alternatives sooner then wait until we run out of coal, and in the meantime, put God knows how many trillions of tons of CO2 that used to be buried underground into the atmosphere.
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.
CO2 cannot cause global warming. I'll tell you why. It doesn't mix well with the atmosphere, for one. For two, its specific gravity is 1 1/2 times that of the rest of the atmosphere. It heats and cools much quicker. Its radiative processes are much different. So it cannot - it literally cannot cause global warming.
I think the whole human-induced greenhouse gas thing is a red herring.
.. . I see climate change as due to the ocean circulation pattern. I see this as a major cause of climate change... . These are natural processes. We shouldn't blame them on humans and CO2.
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.
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.
Organisms dont think of CO2 as a poison.
Plants and organisms that make shells, coral, think of it as a building block.
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.
The European Union and environmental advocacy groups use global warming hysteria to advance their own special agendas. The European Union recognizes any significant reduction in CO2 emissions by the United States will significantly reduce its economic output, thereby bringing it closer to the inferior output of European nations.
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.
On the environmental front there's concern about global warming and high levels of carbon dioxide, and trees take in CO2 and store carbon.
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 think any public policy that doesn't account for the fact that most CO2 emissions don't come from the United States, but they come from other countries, is a flawed policy. So let's not unilaterally tax our power, our people, to solve a global problem.
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.
...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.
