Meet the giant air-sucking wall that might help combat climate change.
Think of it as a giant, high-tech, Earth-saving Lego wall.
Do me a favor and stare at the air in front of you.
Yep — right in front of you. I know you can't see it, but you're staring at a lot of carbon dioxide.
Carbon dioxide naturally cycles between living things and the environment. Think back to your second grade photosynthesis lessons: photosynthesis happens when plants take carbon dioxide out of the air and convert it into oxygen. Then humans and animals breathe in that oxygen, breathing out carbon dioxide ... and on and on the cycle goes.
What's new to this equation, though, is the carbon dioxide we've artificially added to that natural cycle.
Carbon dioxide emissions increased by 7% between 1990 and 2013, according to the Environmental Protection Agency. Carbon that would have previously been stored underground and released slowly (or not at all) is now being released rapidly, mostly because of industry and electricity. Traffic emissions alone — the carbon dioxide released by vehicles — account for almost 60% of those extra fumes.

But here's the issue: while carbon emissions have increased, our planet still absorbs the same amount of carbon dioxide, meaning that there's more in the environment than ever before (cue: global warming).
That's why a group of Canadian engineers are constructing a wall that sucks carbon dioxide right out of the air.
Yep, you read that right. Rather than letting that extra carbon dioxide hang out, these carbon engineers want to reduce the threat of climate change by absorbing CO2 molecules and creating carbon-neutral fuels.
This carbon-dioxide-sucking wall (which doesn't exist yet) will do the carbon sucking work of millions of trees. Photo via Carbon Engineering.
These engineers built a prototype of the technology in Squamish, Canada, an hour's drive north of Vancouver.
Basically, the wall will be made up of a stack of cubes, each of which will function in the same way. This means that you could make a wall whatever size you choose in whatever location you choose, simply by adding more "cubes" (think of it as a giant version of a high-tech Lego wall).
How does the prototype work? First, a fan in the "air contactor" sucks in air molecules (only 1 in every 2,500 of which is CO2), which pass through the air contactor and come into contact with carbon-absorbent surfaces. Then the carbon molecules react, becoming a liquid that is eventually hardened into solid carbonate pellets (think: tiny white pebbles made of carbon). And, finally, high temperatures melt those pellets to release pure carbon dioxide, components of which can be used as fuel.
The most useful result of this technology will be carbon-neutral fuels.
Right now, scientists have built only one prototype unit, which functions in three steps. Photo via Carbon Engineering.
Right now, Carbon Engineering CEO Adrian Corless says that the carbon produced by this technology represents a negative emission. "You've taken it out of the atmosphere," he told Upworthy, "and that's cool because it could restore balance from a climate point of view."
And, eventually, you might be able to use the carbon-neutral fuel (produced by the wall) in your vehicle, reducing carbon emissions while keeping the carbon cycle balanced, too.
For now, this is a very cool idea still in its infancy, Corless says.
They have a prototype, but the next step will be to build a pilot plant that produces fuel (one unit can produce 40 million liters of fuel per year!). Corless says that, eventually, he'd like to see a wall of these prototype units erected in Squamish, too.
In the long term, these walls could also be installed anywhere folks have space — in extra fields or even in city parking lots — solving both the carbon problem and the fuel problem for our country.

An Irish woman went to the doctor for a routine eye exam. She left with bright neon green eyes.
It's not easy seeing green.
Did she get superpowers?
Going to the eye doctor can be a hassle and a pain. It's not just the routine issues and inconveniences that come along when making a doctor appointment, but sometimes the various devices being used to check your eyes' health feel invasive and uncomfortable. But at least at the end of the appointment, most of us don't look like we're turning into The Incredible Hulk. That wasn't the case for one Irish woman.
Photographer Margerita B. Wargola was just going in for a routine eye exam at the hospital but ended up leaving with her eyes a shocking, bright neon green.
At the doctor's office, the nurse practitioner was prepping Wargola for a test with a machine that Wargola had experienced before. Before the test started, Wargola presumed the nurse had dropped some saline into her eyes, as they were feeling dry. After she blinked, everything went yellow.
Wargola and the nurse initially panicked. Neither knew what was going on as Wargola suddenly had yellow vision and radioactive-looking green eyes. After the initial shock, both realized the issue: the nurse forgot to ask Wargola to remove her contact lenses before putting contrast drops in her eyes for the exam. Wargola and the nurse quickly removed the lenses from her eyes and washed them thoroughly with saline. Fortunately, Wargola's eyes were unharmed. Unfortunately, her contacts were permanently stained and she didn't bring a spare pair.

Since she has poor vision, Wargola was forced to drive herself home after the eye exam wearing the neon-green contact lenses that make her look like a member of the Green Lantern Corps. She couldn't help but laugh at her predicament and recorded a video explaining it all on social media. Since then, her video has sparked a couple Reddit threads and collected a bunch of comments on Instagram:
“But the REAL question is: do you now have X-Ray vision?”
“You can just say you're a superhero.”
“I would make a few stops on the way home just to freak some people out!”
“I would have lived it up! Grab a coffee, do grocery shopping, walk around a shopping center.”
“This one would pair well with that girl who ate something with turmeric with her invisalign on and walked around Paris smiling at people with seemingly BRIGHT YELLOW TEETH.”
“I would save those for fancy special occasions! WOW!”
“Every time I'd stop I'd turn slowly and stare at the person in the car next to me.”
“Keep them. Tell people what to do. They’ll do your bidding.”
In a follow-up Instagram video, Wargola showed her followers that she was safe at home with normal eyes, showing that the damaged contact lenses were so stained that they turned the saline solution in her contacts case into a bright Gatorade yellow. She wasn't mad at the nurse and, in fact, plans on keeping the lenses to wear on St. Patrick's Day or some other special occasion.
While no harm was done and a good laugh was had, it's still best for doctors, nurses, and patients alike to double-check and ask or tell if contact lenses are being worn before each eye test. If not, there might be more than ultra-green eyes to worry about.
