Today we travel to a future where we try to break up with cement. Can it be done? How did cement because so ubiquitous? And what’s so bad about cement in the first place?

Climate change and population growth will combine in the twenty-first century to put an enormous load on humanity’s bio-infrastructural support system, the planet Earth. Kim Stanley Robinson argues that our current economic system undervalues both the environment and future human generations, and it will have to change if we hope to succeed in dealing with the enormous challenges facing us. Science is the most powerful conceptual system we have for dealing with the world, and we are certain to be using science to design and guide our response to the various crises now bearing down on us. A more scientific economics — what would that look like? And what else in our policy, habits, and values will have to change?
Winner of Hugo, Nebula and Locus Awards, Kim Stanley Robinson is best known for his award-winning Mars trilogy. He has published fifteen novels and several short stories collections, often exploring ecological and sociological themes. Recently, the US National Science Foundation has sent Robinson to Antarctica as part of their Antarctic Artists and Writers Program. In April 2011, Robinson presented his observations on the cyclical nature of capitalism at the Rethinking Capitalism conference, University of California, Santa Cruz. In 1984, he published his doctoral dissertation, The N…
Richard Sennett, one of the world’s leading thinkers on the urban environment, traces the relationship between how cities are built and how people live in them.
In describing how cities such as Paris, Barcelona and New York assumed their modern forms, Sennett explores the intimate relationship between the good built environment and the good life.

"Adapting to Sea Level Rise: The Science of New York 2140": Legendary science ficiton author Kim Stanley Robinson returns to The Interval to discuss his just released novel New York 2140. Robinson will discuss how starting from the most up to date climate science available to him, he derived a portrait of New York City as "super-Venice" and the resilient civilization that inhabits it in his novel. In 02016 Robinson spoke at The Interval about the economic ideas that inform New York 2140. He will be joined by futurist Peter Schwartz in conversation after his talk.
Professor Matt Ridley explains some basics about just why we should not be in fear of "man-made" climate change. Speech was at the Royal Society, UK on the 17th October, 2016.

Jesse Ausubel: Nature is Rebounding: Land- and Ocean-sparing through Concentrating Human Activities - The Long Now
In the field of environmental progress the conflict between anecdote and statistics is so flagrant that most public understanding on the subject is upside down.
We worry about the wrong things, fail to worry about the right things, and fail to acknowledge and expand the things that are going well.
For decades at Rockefeller University Jesse Ausubel has assembled global data and trends showing that humanity may be entering an exceptionally Green century.
The most important trend is “land-sparing”—freeing up ever more land for nature thanks to agricultural efficiency and urbanization.
Ausubel notes that we are now probably at “peak farmland“ (so long as we don’t pursue the folly of biofuels).
Forests are coming back everywhere in the temperate zones and in many tropical areas, helped by replacing wild logging with tree plantations.
Human population is leveling rapidly and we are now probably at “peak children.”
Our energy sources continue to “decarbonize,” and a long-term “dematerialization” trend is reducing the physical load of civilization’s metabolism.
In the ocean, however, market hunting for fish remains highly destructive, even though aquaculture and mariculture are taking off some of the pressure.
In this area, as in the others, rigorous science and inventive technology are leading the way to the mutual flourishing of humanity and nature.
This week Guardian science editor Ian Sample meets particle physicist Professor Jonathan Butterworth from University College London to talk about his new book Smashing Physics. It’s an insider’s account of one of the most momentous scientific breakthroughs of our times: the discovery of the Higgs boson announced in July 2012.
Jon discusses what it’s like to work on the largest science experiment in history and why such ambitious – and costly – endeavours benefit us all.
Next up, British Association media fellow Nishad Karim reports from the UCL Symposium on the Origins of Life. Be it life on Earth or life elsewhere in the universe, this symposium covered it all with a range of experts from cosmology and biology to meteorology, discussing some very big questions. Where did we come from? Did life begin on Earth or elsewhere? Are we alone?
Nishad spoke to several of the presenters including Dr Zita Matins, an astrobiologist from Imperial College London, and Dr Dominic Papineau, a geochemist from UCL. Dr Martins is a specialist in finding organic material essential for life in meteorites, and Dr Papineau looks for old organic life a little closer to home, analysing Earth rocks.
Other speakers included Dr Francisco Diego, a UCL cosmologist, who discussed the life of the universe itself from beginning to now, 13.8bn years later.
And finally, Ian asks Guardian environment writer Karl Mathiesen whether 2014 will be the hottest year on record.
Legendary scientist David Deutsch puts theoretical physics on the back burner to discuss a more urgent matter: the survival of our species. The first step toward solving global warming, he says, is to admit that we have a problem.
Once long past, listening gave clues for survival. Now we listen unconsciously, blocking noise and tuning in to what we want to hear. Yet the unwanted sounds we filter out tell us a lot about our environment and our lives. Broadcaster Teresa Goff listens for the messages in our walls of sound.
As civilization has become more mechanized, more urbanized and more digitized, the amount of noise has increased in tandem. This noise, according to Garrett Keizer, author of The Unwanted Sound of Everything We Want: A Book about Noise , "is a window for understanding some of the paradoxes and contradictions of being human." If you take the sum total of all sounds within any area, what you have is an intimate reflection of the social, technological, and natural conditions of that place.
Hildegard Westerkamp, a founding member of the World Forum for Acoustic Ecology, says that "Environmental sound is like a spoken word with each sound or soundscape having its own meanings and expressions." So when you listen to the noise, what does it have to tell you? "Noise is a pit of interpretation," says noise musician Brian Chippendale. Broadcaster Teresa Goff goes into the pit with her documentary, The Signal of Noise.
