...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.

So how can we test the idea that the transition from nonlife to life is simple enough to happen repeatedly? The most obvious and straightforward way is to search for a second form of life on Earth. No planet is more Earth-like than Earth itself, so if the path to life is easy, then life should have started up many times over right here.
It seems to be a general rule that sciences begin their development with the unusual. They have to develop considerable sophistication before they interest themselves in the commonplace.
[Bacteria are the] dark matter of the biological world [with 4 million mostly unknown species in a ton of soil].
I called it ignose, not knowing which carbohydrate it was. This name was turned down by my editor. 'God-nose' was not more successful, so in the end 'hexuronic acid' was agreed upon. To-day the substance is called 'ascorbic acid' and I will use this name.
A lot of the things you see in science fiction revolve around black holes because black holes are strong enough to rip the fabric of space and time.
My interest in science started quite early. My earliest school recollection, from age 6, is actually of mathematics, realizing that one could fill an entire page with digits and never come to the largest possible number, so I saw what was meant by infinity.
