Only by advocating 'politically unrealistic' CO2 concentrations can runaway global warming be avoided. But what is politically realistic for humans is whollymunrelated… — Mark Lynas Copy Share Image
To reduce modern climate change to one variable, CO2, or a small proportion of one variable - human-induced CO2 - is not… — Ian Plimer Copy Share Image
CO2 is a minor player in the total system, and human CO2 emissions are insignificant compared to total natural greenhouse gas emissions.… — Jonathan Duhamel Copy Share Image
The scientists who do climate research understand that much of the ever increasing concentration of CO2 in the atmosphere since 1850 must… — John Olver Copy Share Image
People sometimes say we need to be really almost on a wartime footing if you want to change. Our whole economy is… — Elizabeth Kolbert Copy Share Image

Investigations during the last few decades have brought hydrogen instead of carbon, and instead of CO2 water, the mother of all life,… — Albert Szent-Gyorgyi Copy Share Image
I thought if the climate was heating that CO2 was the only forcing, and it would be late in the century before… — Paul R. Ehrlich Copy Share Image
By geo-historical standards, today's atmospheric CO2 levels are remarkably - indeed dangerously - low. We need CO2 in the air to support… — Roger Helmer Copy Share Image
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… — Bill Gates Copy Share Image
I think all countries need to aim to cut the CO2 emissions per person, taking account of externalities like imports and exports. — Martin Rees Copy Share Image
I think the whole human-induced greenhouse gas thing is a red herring... . I see climate change as due to the ocean… — William M. Gray Copy Share Image
We have to remove the CO2 that the industrial economy has already emitted, which otherwise will remain in the atmosphere for hundreds… — Graciela Chichilnisky Copy Share Image

...a magical CO2 knob for controlling weather and climate simply does not exist! — Willie Soon Copy Share Image
I am troubled by the lack of common sense regarding carbon dioxide emissions. Our greatest greenhouse gas is water. Atmospheric spectroscopy reveals… — Michael Myers Copy Share Image
The science is clear that there is an increase in the amount of CO2 in the atmosphere. What is not clear from… — Jim Sensenbrenner Copy Share Image
Just like you could dump oil into the Cuyahoga in the 60s and let someone else foot the bill, today you can… — Ramez Naam Copy Share Image
