...99 percent confident that the world really was getting warmer and that there was a high degree of probability that it was due to human-made greenhouse gases.

Adding CO2 to the air is like throwing another blanket on the bed.
Interpretation
What this quote means
The quote illustrates how increasing carbon dioxide levels in the atmosphere intensifies the greenhouse effect, similar to adding more layers of insulation.
James Hansen's quote compares the accumulation of carbon dioxide in the atmosphere to adding another blanket to a bed, highlighting how each layer contributes to an increase in temperature. Just as a blanket traps heat, CO2 traps heat in the Earth's atmosphere, exacerbating global warming and climate change. This metaphor effectively conveys the urgency of addressing carbon emissions and understanding their impact on our environment.

Coral reefs, the rain forest of the ocean, are home for one-third of the species of the sea. Coral reefs are under stress for several reasons, including warming of the ocean, but especially because of ocean acidification, a direct effect of added carbon dioxide. Ocean life dependent on carbonate shells and skeletons is threatened by dissolution as the ocean becomes more acid.

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

We have at most ten years - not ten years to decide upon action, but ten years to alter fundamentally the trajectory of global greenhouse emissions... We are near a tipping point, a point of no return, beyond which the built in momentum and feedbacks will carry us to levels of climate change with staggering consequences for humanity and all of the residents of this planet.

'Goals' and 'caps' on carbon emissions are practically worthless, if coal emissions continue, because of the exceedingly long lifetime of carbon dioxide in the air.

It is easy to obtain confirmations, or verifications, for nearly every theory-if we look for confirmations. Confirmations should count only if they are the result of risky predictions... A theory which is not refutable by any conceivable event is non-scientific. Irrefutability is not a virtue of a theory (as people often think) but a vice. Every genuine test of a theory is an attempt to falsify it, or refute it.

It is seen that both matter and radiation possess a remarkable duality of character, as they sometimes exhibit the properties of waves, at other times those of particles. Now, it is obvious that a thing cannot be a form of wave motion and composed of particles at the same time - the two concepts are too different.
