...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.

The danger is that the compromises and special interests inherent in Kyoto-style targets and cap-and-trade will be accepted because of bureaucratic momentum.
Interpretation
The quote warns against blindly accepting complex environmental policies without scrutiny due to bureaucratic pressure.
James Hansen emphasizes the risks associated with environmental agreements like Kyoto-style targets and cap-and-trade systems. He suggests that these frameworks, while intended to combat climate change, may lead to compromises influenced by special interests and bureaucratic momentum, which could ultimately undermine their effectiveness and lead to suboptimal outcomes if not critically evaluated.
In practice
This quote can be used in a discussion about the effectiveness of international environmental agreements.
...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.
We need to send a message to Congress and the president that we want them to take the actions that are needed to preserve climate for young people and future generations and all life on the planet.
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.
The strongest affection and utmost zeal should, I think, promote the studies concerned with the most beautiful objects, most deserving to be known.
Language is only the instrument of science, and words are but the signs of ideas.
The challenge of global warming should stimulate a whole raft of manifestly benign innovations - for conserving energy and generating it by 'clean' means (biofuels, innovative renewables, carbon sequestration, and nuclear fusion).
Whenever we find, in two forms of life that are unrelated to each other, a similarity of form or of behaviour patterns which relates to more than a few minor details, we assume it to be caused by parallel adaptation to the same life-preserving function.
Physics is the only profession in which prophecy is not only accurate but routine.
People often ask me why I persisted in doing research on a subject that was so controversial. I frequently respond by telling them that only a few scientists are granted the great fortune to pursue topics that are so new and different that only a small number of people can grasp the meaning of such discoveries initially.
