We Are in the Anthropocene Epoch

- Adam Clare

Human civilization has undoubtedly changed the surface of the planet on a massive scale. There will be evidence of our civilization’s impact for millions of years to come. This may not strike you as good news considering it implies we’ve altered the planet in a way only nature itself could have done.

The good news comes from the fact that the Anthropocene Working Group has reached the conclusion that we are indeed in this epoch. This means that geological research and theory has a new intellectual framework to better our understanding of the world and how we as a species interact with it.

“Like any geological boundary, it is not a perfect marker – levels of global radiation really rose in the early 1950s, as salvoes of bomb tests took place,” said Dr Jan Zalasiewicz, of the University of Leicester’s Department of Geology and chair of the Anthropocene Working Group.

“But it may be the optimal way to resolve the multiple lines of evidence on human-driven planetary change. Time – and much more discussion – will tell.”

The term ‘Anthropocene’ was first coined by Nobel Prize winning chemist Paul Crutzen who in 2000 suggested that man’s impact on the world was so substantial that we were no longer in the Holocene – the era which began at the end of the last Ice Age around 11,700 years ago and saw unprecedented human expansion and the emrgency of towns and cities.

Copenhagen Designed a Neighbourhood to Cope With Climate Change

- Adam Clare

Climate change is happening faster than projected and this means that cities need to react sooner than anticipated. We’ve seen efforts in New York that will create barriers against rising sea levels and other cities have done similar infrastructure improvements. Copenhagen has taken the next logical step: converting an existing neighbourhood into one ready for climate change.

The redesigned chunk of the city use vegetation and reigned streetscapes for a future-proof city.

They went for the green option. “Adding sewers is insanely costly, so a green-and-blue [vegetation and water] approach is more economical,” notes Esben Alslund-Lanthén, an analyst at the Copenhagen-based sustainability think tank Sustainia. There was just one challenge: No city has ever tried climate-change-adapting a whole neighborhood using just plants and water. “It’s a huge amount of water that we’ll have to redirect when the next cloudburst hits,” says Flemming Rafn Thomsen of Tredje Natur, the Danish architecture firm chosen for the project. “We looked at St. Kjeld and thought, ‘That’s a lot of asphalt with no function. We can use some of that space for water.’” On top of having little function, the asphalt gave St. Kjeld, a somewhat rundown working-class neighborhood, an even more depressing feel.

The answer, Rafn Thomsen and the city decided, was to tear up the neighborhood’s squares and replace their asphalt covering with what’s essentially a hilly, grassy carpet interspersed with walking paths. Should a storm, flood or rising sea levels hit the Danish capital again, the bucolic mini-parks will turn into water basins, the hills essentially functioning as the sides of a bowl. Thanks to a new pipe system, the squares will even be able to collect water from surrounding buildings’ roofs. Surrounding streets will, for their part, be turned into “cloudburst boulevards.” Under ordinary circumstances, they’ll just be ordinary streets with raised sidewalks, but during floods and megastorms, they’ll become canals, channeling rainwater away from the squares to the harbor. Millions of gallons of water will be dispatched back to the harbor on such aboveground waterways, St. Kjeld becoming a temporary Venice.

Burlington Vermont Now 100% Powered by Renewable

- Adam Clare

The community of Burlington, Vermont have gotten their power grid to be fully renewable – they are so good at it that they can sell surplus energy to other places. Burlington is known for being a progressive place and they are clearly leading the renewable energy path in the USA. It’s the first city to be 100% powered by renewable energy in the country.

Burlington, Vermont, the state’s largest city, recently became the first in the country to use 100 percent renewable energy for its residents’ electricity needs. In a state known for socially conscious policies, the feat represents a milestone in the growing green energy movement. NewsHour’s William Brangham reports on the implications for the country’s green movement.

Travel to Become a Better Person

- Adam Clare

When friends ask for life advice tell them to leave. Over at BBC Travel they have an article about how travelling can make you a better person. So what are you waiting for? Get out and explore the world!

You’ll gain a broader perspective

As Twain’s quote emphasises, travel can open people’s minds and allow them to see things from a new perspective.

“When you travel, you are faced with alternative cultures that have a different way of doing, thinking and believing,” said Simon Huggins. “It challenges your assumptions and makes you shift your way of looking at things. When you get home, you come back to your own culture with different eyes and a more questioning mind.”

Energy From Drinking Water

- Adam Clare

Drinkable water right from a tap in your home is a relatively new and amazing thing. Just when you thought water delivery systems couldn’t get any better a company has converted pipes into energy generators. Their new pipes can capture energy from water as it flows to its destination to provide a small amount of energy for communities.

“We have a project in Riverside, California, where they’re using it to power streetlights at night,” Semler says. “During the day, when electricity prices are high, they can use it to offset some of their operating costs.”

In Portland, one of the city’s main pipelines now uses Lucid’s pipes to make power that’s sent into the grid. Though the system can’t generate enough energy for an entire city, the pipes can power individual buildings like a school or library, or help offset a city’s total energy bill. Unlike wind or solar power, the system can generate electricity at any time of day, regardless of weather, since the pipes always have water flowing through them.
