    Way to capture Carbon Dioxide

    Chatting last night with my daughter living at Hawaii, I commented that if she wants to see if the politicians are serious about climate change, watch what they do. Do they construct dikes for rising seas? Do they put a lot of effort into new technology that removes carbon dioxide from the air?

    Well, this scientist has a lot of experience at removing carbon dioxide.

    First something to read followed by a video.

    LONDON, England (CNN) -- Scientists in the United States are developing a "synthetic tree" capable of collecting carbon around 1,000 times faster than the real thing.
    A conceptual design of how the "synthetic tree" might look should they ever reach the stage of production.





    As the wind blows though plastic "leaves," the carbon is trapped in a chamber, compressed and stored as liquid carbon dioxide.
    The technology is similar to that used to capture carbon from flue stacks at coal-fired power plants, but the difference is that the "synthetic tree" can catch carbon anytime, anywhere.
    "Half of your emissions come from small, distributed sources where collection at the site is either impossible or impractical," said Professor Klaus Lackner, Ewing-Worzel Professor of Geophysics in the Department of Earth and Environmental Engineering at Columbia University.

    It's not about climate, it's about a happy tax.

    I honestly don't mind them constructing carbon dioxide removal systems. This to me would show real progress.

    Ants help trap CO2 too.

    They may only be tiny, and live for just three months, but ants could be the key to solving climate change.



    Rough harvester ants have been found to ‘weather’ minerals in sand to produce calcium carbonate, also known as limestone.



    When the ants make this limestone, the process traps carbon dioxide in the rock, ultimately removing it from the atmosphere.

    Global warming contributing to greening of the earth...

    Rise in CO2 has 'greened Planet Earth'
    Mon, 25 Apr 2016 - The emissions of carbon dioxide from industrial society has spurred a huge growth in trees and other plants, says a report.
    A new study says that if the extra green leaves prompted by rising CO2 levels were laid in a carpet, it would cover twice the continental USA. Climate sceptics argue the findings show that the extra CO2 is actually benefiting the planet. But the researchers say the fertilisation effect diminishes over time. They warn the positives of CO2 are likely to be outweighed by the negatives.

    The lead author, Prof Ranga Myneni from Boston University, told BBC News the extra tree growth would not compensate for global warming, rising sea levels, melting glaciers, ocean acidification, the loss of Arctic sea ice, and the prediction of more severe tropical storms. The new study is published in the journal Nature Climate Change by a team of 32 authors from 24 institutions in eight countries.


    The greening of Planet Earth

    It is called Greening of the Earth and its Drivers, and it is based on data from the Modis and AVHRR instruments which have been carried on American satellites over the past 33 years.The sensors show significant greening of something between 25% and 50% of the Earth's vegetated land, which in turn is slowing the pace of climate change as the plants are drawing CO2 from the atmosphere. Just 4% of vegetated land has suffered from plant loss.

    This is in line with the Gaia thesis promoted by the maverick scientist James Lovelock who proposed that the atmosphere, rocks, seas and plants work together as a self-regulating organism. Mainstream science calls such mechanisms "feedbacks". The scientists say several factors play a part in the plant boom, including climate change (8%), more nitrogen in the environment (9%), and shifts in land management (4%). But the main factor, they say, is plants using extra CO2 from human society to fertilise their growth (70%).

    Get much below 200ppm CO2 in the atmosphere and plant life will start dying off. Immediate effect- vegetarians pout. Long term effect if CO2 levels don't rise- we die.

    The article says it's better than 1,000 trees. Heaven help us, if this technology were not available, we might have to plant forests of the real thing, and then be surrounded by cool, leafy greenness!

    I wonder how much carbon a 22,000 mile long 30 foot diameter space elevator tether of carbon buckyball monofilament would sequester?

    Question

    A safer way to store CO2?...

    New carbon dioxide storage method has potential: scientists
    Sat, Jun 11, 2016 - For the first time, scientists have successfully injected carbon dioxide into volcanic basalt soil and changed it to a solid, offering a promising way to store underground the greenhouse gas linked to climate change.
    Scientists were able to pump carbon emissions into the earth and change the gas to a solid for storage within months — radically faster than previous predictions that suggested the process could take hundreds or even thousands of years. The study, published on Thursday in the journal Science, was part of pilot project Carbfix, launched in 2012 at Iceland’s Hellisheidi geothermal power plant. Scientists and engineers experimented with combining carbon dioxide and other gases with water and then piping the mixture underground.

    GLOBAL WARMING

    They aimed to develop a method to safely store carbon dioxide that would otherwise escape into the atmosphere and contribute to global warming. The Hellisheidi plant, the world’s largest geothermal facility, energizes Reykjavik by pumping volcanically heated water to power turbines. The process produces 40,000 tonnes of carbon dioxide a year — just 5 percent of the emissions of a similarly sized coal plant, but significant nonetheless. For years, researchers have suggested limiting global warming by using carbon capture and sequestration methods like this one, but developing the technology proved challenging. In nature, basalt in contact with carbon dioxide and water produces a chemical reaction resulting in a chalky, white mineral.

    REACTION TIME

    However, scientists were unsure how long the reaction would take: Previous studies estimated the solidification could take upward of millennia. The basalt under Hellisheidi proved optimal, with 95 percent of the injected carbon dioxide solidifying in less than two years. “This means that we can pump down large amounts of carbon dioxide and store it in a very safe way over a very short period of time,” said study co-author Martin Stute, a hydrologist at Columbia University’s Earth Observatory. “In the future, we could think of using this for power plants in places where there is a lot of basalt — and there are many such places.”
