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.
James HansenRead
...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.
Interpretation
The quote expresses a strong belief in the reality of climate change and its human causes.
James Hansen's quote underscores the significant confidence he has in the scientific consensus surrounding climate change, specifically attributing it to human activities that produce greenhouse gases. He emphasizes the importance of acknowledging this reality to motivate action against climate change and its consequences.
In practice
In a conference on climate action, I would quote Hansen to emphasize the urgent need for sustainability measures.
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.
On a per capita basis, Britain is responsible for more of the carbon dioxide now in the atmosphere than any other nation on Earth because it has been burning it from the dawn of the Industrial Revolution.
Ants make up two-thirds of the biomass of all the insects. There are millions of species of organisms and we know almost nothing about them.
It is a profound and necessary truth that the deep things in science are not found because they are useful; they are found because it was possible to find them.
[N]o scientist likes to be criticized. ... But you don't reply to critics: "Wait a minute, wait a minute; this is a really good idea. I'm very fond of it. It's done you no harm. Please don't attack it." That's not the way it goes. The hard but just rule is that if the ideas don't work, you must throw them away. Don't waste any neurons on what doesn't work. Devote those neurons to new ideas that better explain the data. Valid criticism is doing you a favor.
We should've asked China to be a portion of the space station. We should've worked out ways that we can... just give away the technology that we have that puts things up into space, with cooperation up above the atmosphere that's needed to help each other.
If it could be demonstrated that any complex organ existed, which could not possibly have been formed by numerous, successive, slight modifications, my theory would absolutely break down. But I can find no such case.
Theory attracts practice as the magnet attracts iron.
