uHoo edges out other air quality monitors with extra sensors
We've now gotten to the point where we can rely on pigeons for monitoring outdoor air quality, and there are plenty of conventional options for indoor as well. But there's always room for improvement, which is why we're looking at the uHoo. Impressively, this pint glass-sized device packs up to five air pollutant sensors, thus allowing it to measure the usual dust and volatile organic compounds, as well as carbon dioxide, carbon monoxide and ozone -- these three can't be detected by most other monitors in the consumer market. On top of that, the uHoo can also keep an eye on the temperature, humidity and air pressure, which comes in handy as these contribute to our wellness, too. The live data is fed to your iOS or Android device via Wi-Fi, and the app will alert you when the air goes bad in one of the rooms.

If that's confusing, the video straightens it right up.
NOAA records the biggest annual increase in CO2 levels
The Mauna Loa Observatory, which has been monitoring carbon dioxide levels since the 1950s under NOAA, has recorded the steepest rise ever within a year-long period. Apparently, the average CO2 level for February 2016 is 404.02 parts per million, 3.76ppm higher than February 2015's and 50ppm higher than what scientists consider a safe level. It broke the previous record set in September 1998, when the observatory detected a 3.70ppm growth over the span of 12 months.
Commercial aircraft get their first global emissions standard
Ground-based vehicles have had emissions standards for a while (just ask Volkswagen), but commercial aircraft like passenger jets? Not so much. However, the world just took one big step toward cleaning up the skies: a total of 23 countries have agreed to set the first international carbon dioxide emissions standard for commercial aircraft. If the measures are adopted as recommended, new airplane models will have to meet the tougher guidelines in 2020. New aircraft from existing model lines will follow suit in 2023, and there will be a complete cutoff for non-standard aircraft in 2028.
Final climate change deal keeps emissions in check, if it sticks
After weeks of work, the United Nations is on the cusp of reaching a deal to prevent climate change... hopefully. A just-published final draft agreement sets some clear targets that include a hefty amount of cooperation. The deal would limit the global temperature increase to "well below" 2 Celsius above pre-industrial levels, and reach a balance in greenhouse gas emissions (that is, as many offsets as there are emitters) by the second half of this century. There would be a progress review every five years, and developing countries would get a helping hand to the tune of $100 billion per year as of 2020.
Draft climate change deal lowers greenhouse gases by 2050
Earth just took a tentative step toward a new, comprehensive plan for improving the environment. Representatives from 195 countries have approved a draft UN climate change agreement that will ask all participants to lower their carbon dioxide emissions. There are still many, many details left to resolve ahead of a final deal (ideally signed next week), but the ultimate goal is to have countries reduce their greenhouse gas levels by 2050, and to eliminate emissions completely between 2060 and 2080.

With it, attendees can get photos of themselves at the game after entering their seat number in the free app. NASA is beginning a long-term study into CO2 absorption on the earth, with the hopeful goal of better sequestering and controlling greenhouse gases. And a new report is out on the fluorescent eel discovery of 2011. While the same marine biologist has just discovered a fluorescent turtle, the eel report says the neon was likely selected to attract a mate.
NASA to study how higher temps affect the Earth's ability to absorb CO2
Our atmosphere's carbon dioxide levels are through the roof -- it's the highest it's ever been at 400 parts per million within the past 400,000 years. The situation would have been much, much worse, however, if it weren't for the Earth's forests and oceans. All the plants, trees, the ocean's salt water, marine plants and animals absorb 50 percent of our carbon dioxide emissions. That's why NASA has launched a multi-year project to figure out how exactly our planet absorbs carbon dioxide, as well as to determine whether Earth's continuously warming environment can affect its absorption rate.
Volkswagen also lied about its gas-powered cars
Volkswagen admitted in September that it used defeat devices aimed at fooling emissions tests in 11 million of its diesel vehicles -- but now its gasoline models are implicated in the scandal as well. On Tuesday, Volkswagen reported that it understated the level of carbon dioxide emissions of about 800,000 vehicles, including gasoline-powered models. This is the first confirmation that some of Volkswagen's gasoline-run vehicles do in fact exceed carbon dioxide emissions. The company didn't provide details in today's revelation, but it said the conclusion comes after conducting internal emissions tests.
Xprize challenge offers $20 million to curb fossil fuel emissions
Sadly, carbon dioxide emissions aren't going away just yet. However, the Xprize crew would like to at least see those emissions do something besides accelerate climate change. They're launching the NRG COSIA Carbon Xprize, a competition that will hand out a total of $20 million to teams that convert fossil fuels' CO2 output into genuinely useful products. The 4.5-year challenge will be separated into two tracks (one for coal emissions, the other for natural gas), both of which will offer a pool of $2.5 million for hitting initial lab milestones and a $7.5 million grand prize for whoever succeeds in the real world.
Here's what a year's worth of carbon dioxide looks like
It's easy to talk about carbon dioxide (CO2) emissions and their effect on our planet, but visualizing them? That's hard. Thankfully, NASA has stepped up to the plate with a computer model that shows how CO2 travels across Earth's atmosphere in the space of a year. As you'll see in the clip below, a lot of gas in the northern hemisphere originates in major pollution centers across Asia, Europe and North America before it drifts across the globe. The abundance of plant life in the spring and summer quickly cuts down on CO2 levels, but the chemical comes roaring back once fall arrives -- and the concentrations are higher than NASA would like to see.
Netatmo Urban Weather Station tells iOS users when it's safe to brave the great outdoors (video)
We haven't seen weather stations garner the same level of clever mobile integration as other pieces of household gear -- like, say, thermostats. Netatmo wants its newly available Urban Weather Station to inject a similar dose of life into a category that some of us still associate with the thermometer by the window. The aluminum tube design certainly gives a fresh look to the WiFi-linked indoor and outdoor sensors, but the real trick is the matching iOS (and eventually Android) app. It's for more than just gauging the wisdom of biking to work: the free app tracks historical trends and shares them with fellow users in a network that Netatmo hopes will provide a better understanding of wider-scale and longer-term trends. The sensors go beyond just obvious air quality, humidity, pressure and temperature conditions as well, flagging noise levels and warning if the CO2 levels are high enough to warrant airing out the house. The $179 price for the Urban Weather Station isn't trivial, but neither is knowing just how well you can cope with your environment.
Panasonic Photosynthesis System converts carbon dioxide to organic material with plant-like efficiency
Greenery may fulfill a superficial need to improve the landscape aesthetic, but plants play a much more critical role in regular life function, converting carbon dioxide to oxygen through a process called photosynthesis. Panasonic is among the companies attempting to replicate this natural procedure through artificial means, and it looks like the Japanese electronics maker is well on its way towards a viable solution. Presenting at the International Conference on the Conversion and Storage of Solar Energy this week, Panasonic announced the development of an Artificial Photosynthesis System, which uses a nitride semiconductor to convert water and carbon dioxide -- a byproduct of factories and power plants -- into an organic material called formic acid, which is used in the manufacturing of dyes and fragrances. Covering the planet in formic acid wouldn't necessarily represent progress, but assuming demand isn't exceeded, it certainly beats CO2. Best yet, Panasonic claims that the system converts the substances at plant-like efficiency rates, or 0.2 percent. Hit up the PR after the break for a more granular look at the company's creation.
Microbial fuel cell produces hydrogen from wastewater without wasting energy
Back in 2005, Bruce Logan and his team of Penn State researchers developed a microbial fuel cell capable of converting poop into power. Now, Logan has refined his system to the point where it can produce hydrogen from wastewater or biodegradable organic materials without using a drop of grid electricity, and without emitting even a hint of carbon dioxide. His approach, outlined in the September 19th issue of the Proceedings of the National Academy of Sciences, involves something known as reverse-electrodialysis (RED) -- a process that harvests energy from the ionic discrepancy between fresh and salt water. Logan's bacterial hydrolysis cell (pictured left) features a so-called RED stack that's comprised of alternating positive and negative ion exchange membranes, which it uses to split water molecules into hydrogen and oxygen. Normally, this process would involve about 25 pairs of membranes, but by using RED technology in conjunction with electricity-producing exoelectrogenic bacteria, Penn State's team was able to extract hydrogen with just five membrane pairs. All told, Logan's cells proved to be about 58 to 64 percent energy efficient, while producing between 0.8 to 1.6 cubic meters of hydrogen for every cubic meter of liquid that passed through the system. The researchers' results show that only one percent of that energy was used to pump water through the cells, which are completely carbon neutral, as well. According to Logan, this breakthrough demonstrates that "pure hydrogen gas can efficiently be produced from virtually limitless supplies of seawater and river water and biodegradable organic matter." Somewhere, the US Navy is taking scrupulous notes. Full PR after the break. [Image courtesy of Penn State / Bruce Logan]
Dry ice makes graphene cheaper, greener, and by the (relative) boatload
Dry ice isn't just great for keeping steaks cold and filling your bathtub with fog, it may also play a major role in producing the miracle metal material graphene. Researchers at Northern Illinois University have discovered that burning magnesium in frozen carbon dioxide produces a thin layer of the hyped-to-the-lattices carbon nanostructure. The so-called dry-ice method has several advantages over previous techniques, not the least of which is the ability to pump out the relative of pencil lead on a much larger scale. It also happens to be faster, cheaper, and more environmentally friendly compared with the lengthy processes involving hazardous chemicals used in most graphene production. It's pretty great news but, honestly, all we want to know is when the stuff is going to start powering super-fast internet connections -- that complete Flying Circus collection isn't going to download itself.
Inhabitat's Week in Green: solar robots that fly, CO2 fabric dye, and the dark silicon that boosts battery life
Each week our friends at Inhabitat recap the week's most interesting green developments and clean tech news for us -- it's the Week in Green. Solar power blazed a trail this week as we took a look at several hot new technologies, starting with SkyFuel's SkyTrough, which is being billed as the world's most efficient solar collector. We also saw solar energy take to the skies as designers unveiled plans for a fleet of high-flying solar robots, and we were surprised to learn that common household dyes could significantly increase the efficiency of photovoltaic panels by optimizing their color absorption spectrum. Speaking of dye, from the realm of wearable tech we also brought you a breakthrough new technique for dying fabric that saves water by utilizing fluid CO2. We also saw a prototype for a wired "safe cuddling" suit for kids that wards off improper touching by sounding an alarm, and if you're a fan of high-tech footwear, check out these tricked-out kicks that do double duty as Wii controllers. This week also saw a tremendous green boost for bits and bytes as the University of Leicester switched on its hyper-efficient ALICE supercomputer, which is ten times more powerful than its predecessor and stands to reduce yearly CO2 emissions by 800 tons. Meanwhile, researchers at UC San Diego revealed work on a new mobile phone chip that harnesses "dark silicon" to boost smartphone battery life by a factor of eleven. We also showcased several efficient autos as Southern California rolled out a fleet of all electric buses that can recharge in 10 minutes flat, and the hyper-miling Avion car embarked on a trip from Canada to Mexico with just 14 gallons of gas. And if you'll be doing some traveling of your own back to school this fall, you wont want to miss this chance to pick up an awesome solar-powered Sakku satchel. Finally, with Labor Day on its way why not upgrade your BBQ with an adorable altoids tin mini grill - it's curiously awesome!
Diffus pollution dress is turned on by CO2, prefers a clean environment
We've seen LED-laced dresses before -- though sometimes we'd rather we hadn't -- but this one here is almost refined enough for us to consider wearing. Stitched together using conductive embroidery, hundreds of LEDs are connected to a CO2 detector and react to its input with anything from a slow pulsating glow to a blinking signal of doom. No mention of Morse code messages, unfortunately, but this is run by an Arduino chip -- which means programming malleability (read: near-limitless possibilities) should be built in. Just know that when you see the next Bond girl communicating with Daniel Craig via her haute tech outfit, we had the idea first. A closeup of the dress and processor awaits after the break.
San Diegans convert carbon dioxide to fuel via solar energy
Being Earth Week and all, it's not too surprising to hear of San Diegans stretching their mental might and figuring out an effective way to convert carbon dioxide to fuel, but according to the University of California, San Diego, that's precisely what they've done. Clifford Kubiak and Aaron Sathrum have reportedly developed a prototype device "that can capture energy from the sun, convert it to electrical energy, and split carbon dioxide into carbon monoxide and oxygen." Interestingly, this concept produces more than just an alternate source of fuel, as CO2 splitting also creates a "useful industrial chemical" in CO, and furthermore, helps reduce a greenhouse gas. Currently, they are building the device using a gallium-phosphide semiconductor, and while the existing rendition still requires "additional energy" outside of sheer sunlight for the process to work, they're hoping that the American Chemical Society will warm up to the idea and give 'em a helping hand.[Via Physorg, thanks Richard N.]
