The debate about communicating apocalyptic climate risks misses the point: The only way to combat their terror is by committing fully to climate action.

This green-roofed castle home in England is cooled by the ocean breeze

Comments Off on This green-roofed castle home in England is cooled by the ocean breeze

With its thick undulating walls and green roof , this villa in England translates the architecture of traditional Celtic fortifications into the language of sustainability. Tonkin Liu Architects ‘s Ness Point House is a castle-like structure that protects its occupants from the elements while achieving a high level of energy efficiency. The house occupies a cliff top site in Dover, South East England, and functions as an airtight shelter that utilizes passive and active sustainable design features. It utilizes heat recovery and solar thermal renewable systems to maximize energy efficiency in the winter, while the long gallery skylight and eco-vents enable passive cooling during the hot summer. Related: A green-roofed Hobbit home anyone can build in just 3 days The undulating plan and inclined sections create a cavernous internal space that offers flexibility of use and captures changing lighting conditions. As if growing out of the land, the house is covered in a vegetative roof that slopes downward at the rear of the site. + Tonkin Liu Architects Via Plataforma Arquitectura Lead photo by Nick Guttridge

New map provides clues into 500-million-year mystery in Earth’s past

Comments Off on New map provides clues into 500-million-year mystery in Earth’s past

1,000 to 520 million years ago, Earth’s climate was undergoing dramatic changes. From icy extremes in what some have termed Snowball Earth , to warmer conditions as an increase in oxygen led to the Cambrian explosion of biodiversity , it’s a period of the planet’s climate history we knew little about – until now. Scientists recently created the first ever global map of plate tectonics during this time, shedding light on their influence on other Earth systems. Tectonic plate movement helps researchers understand how life evolved and how Earth’s climate changed. But there was around a 500-million-year gap that a group of 12 researchers in Australia and Canada just filled in with their new map, which they describe as the “first whole-Earth plate tectonic map of half a billion years of Earth history .” Related: World’s oldest fossils discovered in Canada – and they’re 4 billion years old The researchers were able to draw up the map by studying rocks that formed near where tectonic plates meet or where they ripped apart. The rocks came from Brazil, Ethiopia, and Madagascar. The scientists said the work took them a few decades. Their map offers new details, further back in geological time, than we had before. Two of the co-authors on a paper in press at the journal Gondwana Research wrote a piece for The Conversation detailing their map and the role of plate tectonics in our planet’s climate and the evolution of life. Andrew Merdith of the University of Sydney and Alan Collins of the University of Adelaide said the lack of ancient tectonic maps has made it difficult for researchers trying to unravel the mysteries of the past. They wrote, “Understand ancient plate tectonics and we go someway to understanding the ancient Earth system. And the Earth as it is today, and into the future.” Via The Conversation Images via Andrew S. Merdith, et al.

Scaly Anteater Being Poached to the Point of Extinction

Comments Off on Scaly Anteater Being Poached to the Point of Extinction

Scaly anteaters are so in demand for their meat and scales that the animal is being poaching to extinction. Pangolins look like walking pine cones and can be found across Asia and Africa, but they are so popular as a meal in Vietnam and China that all eight species have recently been upgraded to threatened. In fact, it is getting so hard to keep up with demand that a thriving poaching trade between Asia and Africa has popped up.

But, it's not in business' best interest to ignore the upcoming Rio+20 Earth Summit, especially since the scales of power are tipping to the point where nation states have less and companies have more.

Progression of US Cities Reaching Solar Grid Parity

Comments Off on Progression of US Cities Reaching Solar Grid Parity

Grid parity in cost between solar power and grid-supplied electricity is likely to begin being reached in the US in as little as 2 years, and within the next 25 years, many of the largest metropolitan areas will reach the point where solar is less expensive. An animated map from Energy Self Reliant States shows the picture. This timeline includes no government subsidies in the calculations. It uses a baseine cost of solar power in 2011 at $4.00 per watt, installed. Using the average residential grid supplied electricity price for each metro area, it makes the two assumptions based on present trends to determine when the price of solar drops below grid: the cost of solar decreases by 7% per year, and the grid electricity price increases by 2% per year. Based on these assumptions, the San Diego CA metropolitan area will be at solar parity in 2013, and within the next 25 years, many of the largest metropolitan areas will reach the point where solar is less expensive. via: BoingBoing

Turn the Eiffel Tower Green?

Comments Off on Turn the Eiffel Tower Green?

A concept to turn the Eiffel Tower into a giant green wall has been proposed as a symbolic statement of “the reconciliation of nature and mankind.”The plan calls for 600,000 plants to be attached to the structure using hemp sacks filled with soil as the growth media. An irrigation system comprising 12 tons of tubing would be used to provide water for the plants. The installation would not be permanent, and would be removed after a few years. But, once in place, the installation would help remove an estimated 87.8 tons of CO2 from the atmosphere. “Should it not be the duty of engineers to imagine a new future where nature is brought back into the heart of the city,” said a statement from Ginger, the company behind the proposal. With an estimated cost of nearly 100 million dollars for the project, that’s more than a million dollars per ton of CO2. Hardly the most cost effective carbon sequestration, but certainly a visible one. image: CC-BY 3.0 by Taxiarchos228 via: Sustainablog

Comments Off on How to Build a Solar Oven (Slideshow)

Photo credit: Eric Smith/Creative Publishing International When distilled to their essential parts, solar ovens are really very simple devices. Using little more than a container and reflective surface, they intensify the rays of the sun to the point where they can boil water and cook food…all without the use of trees or fossil fuels . The best part: Making one is a cheap and easy project.
