Scientists have created a method to convert carbon dioxide back into solid coal, a breakthrough that could change the ways carbon is removed from the atmosphere and permanently stored.
It’s one of several recently developed negative emissions techniques that seek to make carbon capture and storage cheaper, safer and more efficient. This particular method was developed by a research team led by RMIT University in Melbourne, Australia, and it uses a liquid metal electrocatalyst, containing nanoparticles of the rare-earth metal cerium, to convert the greenhouse gas into a stable, coal-like solid.
“While we can’t literally turn back time, turning carbon dioxide back into coal and burying it back in the ground is a bit like rewinding the emissions clock,” study co-author Dr. Torben Daeneke told The Independent. “To date, CO2 has only been converted into a solid at extremely high temperatures, making it industrially unviable.”

The world’s leading scientists agree we must slash emissions by 2030 and keep global warming below 1.5 degrees C to avert a truly dangerous future. Carbon pollution poisons our air, water, and soil, threatening our health.
When we protect our planet, we protect ourselves. The Climate Reality Project is calling on the world’s leaders to ACT NOW.
The Drawdown EcoChallenge is a fun and social way to learn about and take action on the 100 climate solutions featured in the seminal work of Paul Hawken “Drawdown.”
From April 4-25, individuals and teams from around the world will take part in simple daily activities to reduce their carbon footprints and delve into the world’s most substantive solutions to global warming. At the end of the Challenge, the teams with the most points will win great prizes, including copies of Drawdown and a one-hour video session with Paul Hawken!
The EcoChallenges are broken down into these sections (with an added note of current participants):

A startup in India is capturing the black particles that float in air pollution and turning them into ink.
Anirudh Sharma was at a conference in India when he noticed black particles accumulating on his white shirt. The specks settling on him were from pollution in the surrounding air.
Byproducts from burning fossil fuels such as gasoline and coal are causing health problems and climate effects around the world, especially in India’s growing cities. In that moment a few years ago, though, Sharma saw the pollution particles as something simpler: A coloring agent.
He went back to MIT Media Lab in Cambridge, Massachusetts, where he was a graduate student focused on augmented reality, and began working on an idea to turn carbon pollution into ink. Using candle soot to start, he came up with a prototype. After finishing his master’s degree, he went back to India and in 2016 co-founded a collaborative called Graviky Labs to continue working on Air-Ink and other ideas.
They developed a device that can be fitted onto the exhaust pipe of a car or portable generator and collected the soot that forms from burning diesel fuel. By mixing the fine black powder with solvents, they produced ink that then went into bottles and markers.
Kaushik says Air-Ink has a dual benefit: “It’s not just that we’re recycling that material into inks. What we are also doing is replacing the carbon black that otherwise would have been used to make black inks.” Manufacturers typically use the soot known as carbon black in rubber, ink, paints, and carbon paper.
After posting their endeavor on Kickstarter earlier this year, the team brought in $41,000—nearly three times the donations they sought to start producing Air-Ink in larger quantities. Through a sponsorship from a beer company, they’d already begun distributing the ink to artists, who created public pieces in London, Singapore, and other cities.

Designer Daan Roosegaarde has installed the “largest smog vacuum cleaner in the world” in Rotterdam to help improve the city’s air quality. The seven-meter-tall structure is designed to create a pocket of clean air in its vicinity, offering a respite from hazardous levels of pollution.
According to the designer, it processes 30,000 cubic meters of air per hour – removing ultra-fine smog particles and pumping out clean air using no more electricity than a water boiler. “The Smog Free Tower produces smog-free bubbles of public space, allowing people to breathe and experience clean air for free,” said a statement from Roosegaarde.
Roosegaarde‘s Smog Free Tower was unveiled on 4 September 2015 at Vierhavensstraat 52, following a successful Kickstarter campaign to help fund the project.
Here is an excerpt from the 2017 APA Mental Health on Climate white-paper:
The ability to process information and make decisions
without being disabled by extreme emotional responses is
threatened by climate change. Some emotional response is
normal, and even negative emotions are a necessary part of
a fulfilling life. In the extreme case, however, they can interfere
with our ability to think rationally, plan our behavior, and
consider alternative actions. An extreme weather event can
be a source of trauma, and the experience can cause
disabling emotions. More subtle and indirect effects of
climate change can add stress to people’s lives in varying
degrees. Whether experienced indirectly or directly, stressors
to our climate translate into impaired mental health that can
result in depression and anxiety (USGCRP, 2016). Although
everyone is able to cope with a certain amount of stress,
the accumulated effects of compound stress can tip a
person from mentally healthy to mentally ill. Even uncertainty
can be a source of stress and a risk factor for psychological
distress (Greco & Roger, 2003). People can be negatively
affected by hearing about the negative experiences of
others, and by fears—founded or unfounded—about their
own potential vulnerability.
PHYSICAL HEALTH AND MENTAL HEALTH
Compromised physical health can be a source of stress
that threatens psychological well-being. Conversely, mental
health problems can also threaten physical health, for
example, by changing patterns of sleep, eating, or exercise
and by reducing immune system function.
Although residents’ mental and physical health affect
communities, the impacts of climate on community health
can have a particularly strong effect on community fabric
and interpersonal relationships. Altered environmental
conditions due to climate change can shift the opportunities
people have for social interaction, the ways in which they
relate to each other, and their connections to the
Until now. Beginning in 2015, a pair of Google Street View cars, equipped with high tech “mobile labs” developed by San Francisco–based startup Aclima, crisscrossed the streets of West Oakland taking second-by-second samples of the area’s air. They tested for nitrogen dioxide and a type of pollution known as black carbon (bad for your heart and lungs, not to mention the planet), as well as nitric oxide. The cars hit every stretch of pavement, from tiny cul-de-sacs to truck-choked Peralta Street, multiple times, taking millions of measurements.
There are three stationary air pollution monitors for all of Oakland, which reveal the city’s air quality as a whole. But the Street View cars can tell you what the air is like at, say, the corner of Market Street and Grand Avenue—basically anywhere you can drive a Street View car. They can even tell you how the air varies from one end of a single block to the other for a truly hi-res view of the problem.The result: one of the largest and most granular data sets of urban air pollution ever assembled in the world.
Quoting Google’s interview on Aclima: “We visited each block on between 20 and 50 different days over the course of a year,” says Joshua Apte, an engineering professor at the University of Texas at Austin. In the process, they were able to identify patterns they wouldn’t have otherwise seen. “If pollution spikes for an instant, it may or may not be such a bad thing. But if pollution is consistently high, that’s something we really should care about.”
Imagine what difference awareness on air pollution can make when this information becomes more accessible!
The single biggest pollution problem facing our ocean is microfiber: trillions of pieces of tiny fibers flowing into the ocean – every time we use our washing machines. Our clothing is breaking up, sending this microfiber (made of plastic and chemical-covered non-plastics) out with the drain water – just one fleece jacket could shed up to 250,000 pieces per garment per wash [source]. New York City, alone, could have 6.8 billion microfibers flowing into its harbor every day. We are all contributing to this problem.

Stand For Trees. Think of it as a global, grassroots intervention to halt deforestation.
Stand For Trees empowers everyday citizens – all of us – to take direct action to protect endangered forests and reduce the impacts of climate change.
Every time you buy a Stand For Trees Certificate, you help local forest communities around the world keep a specific forest standing and prevent a tonne of CO2 from entering the earth’s atmosphere.
You buy a Stand For Trees Certificate — a unique, high-quality, verified carbon credit that protects a specific endangered forest and offsets a tonne of CO2 from entering the earth’s atmosphere. Because of your purchase, forests are left standing to do what they do best — store carbon, produce oxygen, provide habitat, and support local communities.
Stand For Trees Certificates are high-quality verified carbon credits based on the proven REDD+ model and meet the rigorous standards set by the Verified Carbon Standard (VCS), each of which is a Verified Carbon Unit (VCU) issued by VCS. Further, all Stand for Trees projects have attained or are committed to attaining verification to the Climate Community and Biodiversity Alliance standard, a partnership of leading NGOs that includes CARE, The Nature Conservancy, and The Rainforest Alliance. The credits are registered on the world’s largest environmental registry services provider, Markit, and meet Code REDD’s peer-reviewed international Code of Conduct.
What if we all stood up for trees and saved a tonne? The term ‘tonne’ represents a metric ton – a unit of measurement equal to approximately 2,205 pounds or 1,000 kilograms. That’s a lot of CO2 that would otherwise be released into air, contributing to the man-made greenhouse gases that are accumulating and accelerating climate change in our lifetimes.
