...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.
You can't tie a rope around the ice sheet. You can't build a wall around the ice sheets.
Interpretation
What this quote means
The quote emphasizes the impossibility of controlling or containing natural phenomena, such as climate change.
James Hansen's quote illustrates the futility of trying to impose artificial limits on the natural world, specifically in the context of climate change and environmental degradation. It suggests that like an ice sheet that cannot be constrained by a rope or a wall, our efforts to control or ignore the effects of climate change are ultimately ineffective. This serves as a reminder of the need for responsible stewardship of the environment rather than avoidance of the consequences.

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.

I often say that when you can measure what you are speaking about, and express it in numbers, you know something about it; but when you cannot measure it, when you cannot express it in numbers, your knowledge is of a meagre and unsatisfactory kind.
