NOT ENOUGH

CYBERSPACE, OCTOBER 17, 2016 (FUTURISM) A study reports the global commitment to halt emissions and prevent a more than a 2ºC rise in temperatures isn't enough. In the event of not keeping global warming below 2ºC, the paper suggests aggressive carbon capture efforts to suck CO2 out of the atmosphere.

The Paris climate summit last year was praised for increasing global commitment against climate change. And now, the political leaders of the world have reached an agreement to keep the rise in global temperatures below 2°C — a massive win for ecowarriors and planet Earth.

But one study claims it’s simply not enough. A discussion paper by scientist James Hansen says we must do more than stop the 2ºC rise — we must also start sucking CO2 out of the air.

The paper says 2016 temperatures are likely to be 1.25ºC above pre-industrial times and have already reached points similar to when Earth’s seas were 20 to 30 feet higher. That’s the Eemian period, more than 100,000 years ago.

Hansen’s paper, written with 11 other scientists all over the world, argues if we cap global warming at 2°C or even 1.5°C and do nothing else to lower it, we would experience “feedback.” This is when the rising temperatures release more greenhouse gases and further increases global warming.

All this has spurred Hansen, his granddaughter, and other young people to sue the U.S. federal government. The suit claims federal inaction violates the constitutional rights of the youth and will leave the burden to the next generation.

CLIMATE ACTION

The paper does address how we can stave off disaster:

“Technically, it’s still possible to solve the climate problem…but that has two essential requirements,” Hansen says. “That would be… a simple across the board rising carbon fee, which would spur the development of alternative clean energy. Also, I think the government has to be supporting the development of clean energy in a very substantial way…”

Also, the paper says if we are able to sharply reduce global warming, we would only need mild carbon capture solutions, such as planting forests and placing biochar in soil. Both would absorb enough of the GHGs in the atmosphere.

Otherwise, we would have to resort to more drastic carbon capture technologies, like biofuel plants that suck GHGs out of the air and turn them into fuel. References: Insideclimatenews, Co.Exist /futurism.com/?p=55232&post_type=link

New Carbon Capture Method Turns CO2 into Solid Rocks Annette K. Mortensen

IN BRIEF

A team working in Iceland has developed a method that turns CO2 into rocks, using a reaction with volcanic basalt found underground.

FROM AIR TO ROCK

OTHER METHODS

While the study has provided a safe and speedy carbon capture method, other studies have focused on usefulness. A Swiss company called Climeworks is pumping extracted carbon to farms for agricultural use. In its pilot near Zurich, it has constructed a plant that sucks up the air and filters the carbon dioxide (CO2) to be sold by the tons to third parties.

Meanwhile, a Canadian startup has a pilot project to suck CO2 out of the atmosphere and turn it into pellets that can either be used as fuel or stored underground for later. The project will precede construction of a $200 million commercial plant in 2017, which is expected to extract 1 million tonnes per day.

Smog-Sucking Tower: The World’s Largest Air Purifier Comes to Life in China

IN BRIEF

With 98% of large cities in low to middle income countries exceeding healthy air guidelines, one artist is making a difference. The giant air purifier will be carted around China in hopes to spur conversation about pollution.

WORLD’S LARGEST PURIFIER


A powerful idea: The tower is 23-feet-high and collects and processed pollutants before condensing them into a cube

Air pollution is a major concern all around the world today, with leading metropolises blanketed with thick smog most of the year. Of particular note is Beijing, which last year exceeded its national health standard by 1.3 times.

That thick Beijing smog has inspired a designer to take action to the next level. Dutch artist Daan Roosegaarde has created the world’s biggest air purifier, and he’s taking it on a tour of China, starting with Beijing.

He has created a 23-foot (7 m) tower that takes in dirty air and releases air with the tiny dust particles removed. Oh, and by the way, it takes that dust and turns it into jewels. The whole process is part of Roosegaarde’s Smog Free Project.

The tower, dubbed the Smog Free Tower, consists of 45 silver plates housing a huge internal air purifier. That purifier works by releasing positive ions into the air, which latch on to dust particles, particularly PM2.5 and PM10. Negative ions then attract the positive ions back into purifier, bringing the particulates along with them. It then traps the dust, and releases the air back outside, now 75% cleaner.

SPURRING CONVERSATION

The Dutch artist is now touring China, tower in tow. Partnering with China’s Ministry of Environmental Protection, the next leg of the tour will be based on the results of an online poll. He plans for at least 800 units in cities across China.

Unlike other proposed solutions to the air problem, Roosegaarde admits that his invention is not the magic bullet that will make everything go away. He just wants his inventions to start the conversation rolling. “I hope that the designs I make will be part of a mentality change,” he told CNN.

According to the WHO, “98% of cities in low and middle income countries with more than 100,000 inhabitants do not meet WHO air quality guidelines.” This kind of change is vital to our survival.


Will these scenes be history? The tower will be brought to Beijing in September and will be installed in a park in the capital
