We have known since the 1800s that carbon dioxide traps heat in the atmosphere. The right amount keeps the climate conducive to human life.

If we drive our fellow species to extinction, we will leave a far more desolate planet for our descendants than the world we inherited from our elders.

The United States did not sign Kyoto, yet its emissions are not that different from the countries that did sign it.

If humanity wishes to preserve a planet similar to that on which civilisation developed and to which life on Earth is adapted, paleoclimate evidence and ongoing climate change suggest that CO₂ will need to be reduced from its current 385 ppm [parts per million] to at most 350 ppm... If the present overshoot of this target CO₂ is not brief, there is a possibility of seeding irreversible catastrophic effects.

It would be immoral to leave young people with a climate system spiraling out of control.

Rising carbon price is essential to 'decarbonize' the economy - to remove the nation towards the era beyond fossil fuels.

...the global surface albedo [surface whiteness] and greenhouse gas changes account for practically the entire global climate change.
