...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.

In practice
Example use cases
During a climate change awareness event, one might say, 'As James Hansen put it, adding CO2 to the air is like throwing another blanket on the bed, reminding us of the urgent need to reduce emissions.'

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.

As scientists, we step on the shoulders of science, building on the work that has come before us - aiming to inspire a new generation of young scientists to continue once we are gone.
The aim of scientific thought, then, is to apply past experience to new circumstances; the instrument is an observed uniformity in the course of events. By the use of this instrument it gives us information transcending our experience, it enables us to infer things that we have not seen from things that we have seen; and the evidence for the truth of that information depends on our supposing that the uniformity holds good beyond our experience.
Nearly every one of the genes that turns out to be a key player in cancer has a vital role in the normal physiology of an organism. The genes that enable our brains and blood cells to develop are implicated in cancer.
Haemoglobin is a very large molecule by ordinary standards, containing about ten thousand atoms, but the chances are that your haemoglobin and mine are identical, and significantly different from that of a pig or horse. You may be impressed by how much human beings differ from one another, but if you were to look into the fine details of the molecules of which they are constructed, you would be astonished by their similarity.
