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

Good news: The ban on CFC-based asthma inhalers is rapidly approaching. Inhalers are going green and by December 31, all inhalers must be powered by hydrofluoroalkane (HFA) instead of the ozone-harming chlorofluorocarbons (CFCs).

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

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

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.

New NASA study offers first direct proof that the ozone hole is recovering thanks to the Montreal Protocol treaty and the international ban on CFCs.

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

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

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).

We can and should go back and forth about the merits, demerits, risks and potential rewards of the spectrum of geoengineering techniques, from the simple but slow and effective (like afforestation) to the well, more fraught with potential catastrophic

Researchers are working on "reprogramming" cells to create customized organisms that can be used for everything from new medicines to environmental clean-up crews.

Reducing CO2 emissions at the source, or better yet, not emitting them in the first place, is the better option.

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.

Wealthy individuals funding geoengineering feasibility studies because no one else will.

"The stakes are very high and scientists are not the best people to deal with the social, ethical or political issues that geoengineering raises."

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.

It may have also been done under falsely obtained consent...

Because the iron dumped in the ocean off British Columbia wasn't dumped as waste, it didn't violate international law.

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.

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.

Rules really matter, and the city uses them to encourage the right kind of building.

But is it a pyrrhic victory?

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

High rents in the city prompted this young woman to look for an alternative -- in a van conversion.

This modern laneway house is now home to a client who wants to look after her aging parents.

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.

Secretary General Ban Ki-Moon called upon heads of state to make “bold” announcements at today’s Climate Summit.

Today, the United Nations climate talks reached an agreement, and committed to fighting devastating levels of climate change.

The UN Environment Assembly is putting together a "political declaration on pollution," but we need action more than words at this point.

In a few years people around the world, including you, may be sitting on a different kind of toilet.

Japanese designer Chie Imai has created bolero jackets for her fall '08 collection that mix fur from chinchillas with recycled polyester fabric from Teijin Ltd., and she's calling it eco-fur. Imai argues that fur is an 'ecological' product because it can

If the fur-trimmed recycled-polyester bolero jacket we wrote about in Part I of this entry is very questionably eco, what about a bedspread or throw pillows from pesky possums threatening to overrun New Zealand's flora and fauna?

The Greatest Outdoor Gear How do you make the greatest outdoor gear? We went to Empire Canvas Works' Kevin Kinney to find out. If the quality of Kevin's work is any indication, the recipe is clear. Start with a passion seeded by stitching together a

With a slew of fur-free celebrities and PETA's racy anti-fur campaigns, sporting a fur coat is controversial. For reasons that range from the philosophical to the stylistic, Planet Green notes, thousands of old fur coats are sitting

An ad by the European Fur Breeders' Association will not be allowed to run again after the advertising watchdog, ASA, ruled it to be misleading.

City council voted unanimously this week to support a ban.

Max Fordham's house is "simple and practical" and mostly all natural.

But alas, nobody seems to listen to cycling commissioners in the UK.

After a tragic fire caused by plastics, the British building code banned wood in exterior walls. This is a step in the wrong direction.

Wind turbines, solar cells, wave power. If you think these are newfangled technologies, think again. They were fangled long ago, and their story is the meat of Alexis Madrigal's new book, Powering the Dream. Madrigal (a senior editor at The Atlantic and
