Calls came into emergency centers and even the Griffith Observatory from LA residents who described seeing a “giant silvery cloud.”

The only downside, of course, is that your self-lit holiday centerpiece actually would be a Frankenstein tree.

This design is a hybrid of existing concrete sea defenses that can hold a mangrove seedling inside.

Draped in moss, orchids, lilies, and ferns, this city bus transports riders to a whole new world.

Taiwan has the runs on toilet paper as prices rise.

Climate change is powerfully symbolized by severe drought. Extended, widespread drought can make potable water scarce. Desalination plants are energy intensive and expensive to build and run: the several recently build or planned for Australia may

This is the most heartbreaking story we've read all week, and if the idea of a baby whale trailing after a yacht and trying to suckle from it doesn't make you go "awww," then that lump of muscle you call your ticker has been

It's a safe bet that few, if any, of Sydney's bicycle commuters go with penny farthings as their two-wheeler of choice. The outdated ride (popular in the 1870s) is most used these days for its retro value and the

Planning your holiday party schedule in New York City can be calendar jujitsu, what with work parties, friends parties, family parties, but there are also a few green themed parties that the sustainably minded New Yorker

Built on top of an existing garage, this laneway house in Australia makes use of what's already there.

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

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

With people living in smaller spaces and with better toilets, perhaps it is.

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.

The results are often surprising.

The results of our annual survey are often surprising.

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

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

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

Forty percent: That is the share of annual oceanic carbon dioxide uptake accounted for by the Southern Ocean. Given that oceans comprise Earth's largest carbon sink, that is not an insignificant figure;

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

We rely on the sun for everything from powering up our electronics to basic heat and warmth for survival, but this massive star does more than just send light our way: It's a huge nuclear reactor with explosions, eruptions, storms,

Household cleaning products in the U.S. might soon be a little greener, thanks to a new rule in California that will require companies to reformulate products so they contain fewer volatile organic compounds, or

Left: Ozone in Earth's stratosphere at an altitude of approximately 12 miles (20 kilometers) in mid-March 2011, near the peak of the 2011 Arctic ozone loss. Right: chlorine monoxide - the primary agent of chemical ozone destruction in the cold polar

Ben Richmond at Motherboard highlights a climate change success story.

Hopefully someday we can say the same thing about an effective effort to combat greenhouse gas emissions.

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

Late last week at the Convention on Biodiversity a resolution was adopted which places a moratorium on geoengineering unless it can be proven that the method in question can be shown to not have an adverse effect on

Some new research looks at the unintended consequences of injecting aerosols into the atmosphere to block solar radiation and cool the planet, finding that doing so could turn skies everywhere into a brighter, whiter, hazier, ugly mess.

The quest to find a last-ditch techno-fix for climate change is more intense and globe-spanning than you possibly could have imagined. See for yourself.

The first field test of injecting sulfate particles into the atmosphere is proposed for New Mexico; ocean iron fertilization experiment shows more promise than previous ones.

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

Naomi Klein's latest book is about more than just science. She explores the extractivist mentality and historic decisions that have led us to where we now find ourselves, living in a totally unsustainable way.

Most trolley systems were ripped out in favor of diesel buses. This was a big mistake.

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

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