The world’s largest permanent interactive light installation has been installed in Sydney's recently revitalized Darling Quarter.

Sydney sees cycling skyrocket as it implements its 2030 green city plan.

With everything happening in one space, studio apartments can often feel too cluttered. This Sydney apartments gets a space makeover with the addition of a clever multifunctional unit that partitions the space and stores things out of sight.

Decluttering techniques are a big trend now. This small apartment is designed with organizational principles right from the start.

Instead of trashing these old treads, they have been made into a inter-looping work of art in the same station.

Are they good for everyone or just about making money and getting rid of workers?

I think open kitchens are greener and more efficient, but others like a separation.

People are outraged that a bear is shot and killed in a suburban backyard. It's not so simple.

It's a thing of beauty but really expensive. Poll: Hütte or Nüts?

The extremely dated "It ain't easy being green" title of this Trulia survey actually misinterprets the data; judging by the questions they asked, it is perfectly easy being green; it just ain't cheap.

Which of these two images does your place look like?

It would save fuel and be safer for pedestrians and cyclists. But is it too complicated?

Some would pick a third option: vermin.

Our photo of the day comes from the 15th oldest U.S. national park.

Ozone, is a substance that like CO2, seems not only to require international treaties, but it likes cleaning stuff. Apparently NASA discovered it works a treat as a disinfectant, killing bacteria and making stains soluble at low temperatures. The

Ozone — best known for filtering out harmful UV light as a component of the Earth's stratosphere — could dramatically reduce plants' ability to act as a carbon sink and thus cause further accumulation of greenhouse gases in the atmosphere, according to

You can't blame them for trying: With the White House set to change hands in less than a year's time - likely bringing on board a more eco-friendly administration - industry groups have been pressing the EPA to squelch stricter air-quality standards

Talk about a lose-lose situation: On one hand, not taking any action to repair the hole would allow harmful UV radiation to percolate through; on the other hand, helping to accelerate its recovery could strengthen global warming by

While their brethren, the dreaded chlorofluorocarbons (CFCs), may be on the wane, fluorocarbons -- a class of equally dangerous industrial gases -- are still wreaking havoc. As the name implies, the main distinguishing characteristic between CFCs and

Image from NASA updated: As many noted, I (idiotically) cited the Montreal Protocol's success here, which has nothing to do with reducing tropospheric ozone -- rather, it has to do with fixing the ozone layer. Thank you commenters, and my apologies for

Hosed by this theory or greenwashed? Photo by Tony Stl via Flickr On ABC's 20/20 last Friday, Nathan Myhrvold, Microsoft's former chief technology officer, and founder/CEO of Intellectual Ventures (IV), resurrected the idea of stretching a 2-inch

In July of 2007, the East Coast was slammed by a record-setting heat wave. From New York City to Washington, DC, temperatures averaged above 90 degrees Fahrenheit, causing more than 40 deaths.

In late September, NASA's Upper Atmospheric Research Satellite will crash into Earth. Weighing more than 1,300 pounds and roughly the size of a school bus, the satellite will likely land somewhere between Canada and South

Among the more high risk methods of geoengineering, methods that reflect sunlight away from the Earth to counteract temperature rise are right up there in terms of potential unintended consequences. Well, a new piece of

While preservation of the planet's dwindling biodiversity itself has rightly grabbed the headlines at the ongoing Convention on Biological Diversity in Japan, Science Insider points out an important geoengineering

This week two scientists, Dirk Schulze-Makuch and Paul Davies, suggested in the Journal of Cosmology that it is time for humans to start colonizing Mars. Humanity needs some

There's been lots of back and forth in the past year on biochar, ranging from research showing it has huge potential for absorbing carbon emissions on one side, to uncertainty about its potential, to outright

One of the more invasive geoengineering methods that's been proposed to avert global warming is spraying clouds with seawater to whiten them, reflecting solar radiation. New research presented at the European Geosciences Union meeting urges caution

Another report on another geoengineering method that is likely too risky to try and utterly not cost-effective: Injecting aerosols into the atmosphere to slow warming (which would do absolutely nothing about ocean acidification, by the way).

Can humans endure the isolation, self-reliance, and deprivations of travel to Mars and back? Six pale-faced but smiling astronauts answer the question.

Plus, spewing sulfate into sky to stop warming won't fully work (redux); what Singapore's doing to make sure sea level rise doesn't swamp their city. Here's what caught our eye this morning.

Inspired by geoengineering techniques, an artist creates a personal cloud-forming machine to make a point.

Geoengineering can be more than doing stuff to the environment. We could try leaving it alone.

Kevin Kelly explains why the complex interconnectedness of modern technology and society makes disaster relief and system change so challenging.

From now on, thirsty visitors can refill their own bottles at water fountains or grab a reusable cup in the cafeteria.

Billions of chopsticks are thrown out each year worldwide. This Vancouver company is trying to turn some of of these into new items for the home.

The Economist puts Melbourne in number 1 spot, Vancouver in 3. They're not.

A small apartment is made to feel larger with custom cabinetry and more.

I wish them luck but there are a lot of complications.

They may not be the answer to the housing crisis, but they certainly are wonderful little homes.

And that's just the way the architect and developer like it.

The Vancouver architect is famous for "tall wood" but still has a knack for little good wood buildings too.

An old warehouse is transformed into a three-level open office with lots of shared spaces for a tech company in Vancouver.

The United Nations' Intergovernmental Panel on Climate Change (IPCC) was expected to delivery its fifth Assessment Report (AR5) next month, but over the past weekend, a draft of that report was leaked to Reuters, which reported the early findings.

The Intergovernmental Panel on Climate Change (IPCC) has released its fifth assessment report (AR5), which surely must be one of the most important science documents of all time.
