CO2 is a pollutant? Tell that to the plants.
The most difficult task, phase-out over the next 20-25 years of coal use that does not capture CO₂, is Herculean, yet feasible when compared with the efforts that went into World War II. The stakes, for all life on the planet, surpass those of any previous crisis. The greatest danger is continued ignorance and denial, which could make tragic consequences unavoidable.
Our CO2 mixes with everyone else's within a year, then hangs around for centuries like a shroud.
The role of CO2 is not nearly as clear as the climate catastrophists would suggest.
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.
Absolutely love the new campaign from the Optimum Population Trust: do your bit for addressing climate change by having fewer children - or even no children. The lifetime CO2 emissions of a UK citizen amount to 750 tonnes (the equivalent - apparently - of 620 return flights between London and New York), so the extra 10 million by which our population will rise between now and 2074 will, over their lifetimes, emit around 7½ billion tonnes of CO2. . . "births averted" is probably the most single most substantial and cost-effective intervention that governments could be using
Undoubtedly, at the moment, the major cause of CO2 emission is what happens in developed countries.
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.
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.
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.
Many people believe the whole catastrophe is the oil we spill, but that gets diluted and eventually disarmed over time. In fact, the oil we don't spill, the oil we collect, refine and use, produces CO2 and other gases that don't get diluted.
Sunspots and cosmic rays have a 79 percent correlation with our thermometer record since 1860. Meanwhile the CO2 correlation is a mere 22 percent.
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.
It seems that, notwithstanding the dramatic increases in manmade CO2 emissions over the last decade, the world's warming has stopped.
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.
It is a search for a mythical CO2 sink to explain an immeasurable CO2 lifetime to fit a hypothetical CO2 computer model that purports to show that an impossible amount of fossil fuel burning is heating the atmosphere. It is all a fiction.
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.
I am troubled by the lack of common sense regarding carbon dioxide emissions. Our greatest greenhouse gas is water. Atmospheric spectroscopy reveals why water has a 95 percent and CO2 a 3. 6 percent contribution to the 'greenhouse effect. ' Carbon dioxide emissions worldwide each year total 3. 2 billion tons. That equals about 0. 0168 percent of the atmosphere's CO2 concentration of about 19 trillion tons. This results in a 0. 00064 percent increase in the absorption of the sun's radiation. This is an insignificantly small number.
If we don't start thinking big about the CO2 problem, we may miss our opportunity to stop a climate runaway that will trash the habitable parts of the earth.
CO2 is so beneficial. . . it would be crazy to try to reduce it
