    Want a bit of good news? Consider this, plus the fact that we're getting cloer to biomass alternative fuels that will one day eliminate the need for gasoline engines.

    ScienceDaily (Jan. 4, 2012) — Scientists are reporting discovery of an improved way to remove carbon dioxide -- the major greenhouse gas that contributes to global warming -- from smokestacks and other sources, including the atmosphere. Their report on the process, which achieves some of the highest carbon dioxide removal capacity ever reported for real-world conditions where the air contains moisture, appears in the Journal of the American Chemical Society.

    Alain Goeppert, G. K. Surya Prakash, chemistry Nobel Laureate George A. Olah and colleagues explain that controlling emissions of carbon dioxide (CO2) is one of the biggest challenges facing humanity in the 21st century. They point out that existing methods for removing carbon dioxide from smokestacks and other sources, including the atmosphere, are energy intensive, don't work well and have other drawbacks. In an effort to overcome such obstacles, the group turned to solid materials based on polyethylenimine, a readily available and inexpensive polymeric material.

    Their tests showed that these inexpensive materials achieved some of the highest carbon dioxide removal rates ever reported for humid air, under conditions that stymie other related materials. After capturing carbon dioxide, the materials give it up easily so that the CO2 can be used in making other substances, or permanently isolated from the environment. The capture material then can be recycled and reused many times over without losing efficiency. The researchers suggest the materials may be useful on submarines, in smokestacks or out in the open atmosphere, where they could clean up carbon dioxide pollution that comes from small point sources like cars or home heaters, representing about half of the total CO2 emissions related to human activity.

    Recycling CO2 and rainforest challenges...
    :cool:
    New Discovery Promises Efficient Way to Recycle Carbon Dioxide Pollution
    January 06, 2012 - Scientists in the United States say they have discovered a new, inexpensive way to remove excess carbon dioxide, or CO2, from the atmosphere, as well as from large industrial exhaust sources, such as factory smokestacks.

    African Rainforests Continue to Face Challenges
    January 06, 2012 - The African continent contains about 30 percent of the world’s global rainforests, second only to the Amazon. Scientists and conservationists met at Oxford University to discuss changes the forests are expected to undergo in the 21st Century.

    Granny wonderin' if dat's what been makin' it so warm lately?...

    CO2 'drove end to last ice age'
    4 April 2012 - Ice core records from Antarctica had suggested the CO2 increase lagged behind temperature rise

    Determining CO2 from natural sources vs. man-made sources...
    :confused:
    CO2 from fossil fuels discerned from natural sources
    20 April 2012 - Coal and oil contain far less carbon-14 than is contained in the CO2 produced by life today

    Cool.............now we'll have 37 catalytic converters on our cars!!! And Im sure the car companies will eat the cost of the technology!!!:D:D Restriction blows...........I'd just remove them anyway!!

    Ain't been so much CO2 inna air since the dinosaurs was a-fartin'...

    Experts: CO2 record illustrates 'scary' trend
    May 11,`13 WASHINGTON (AP) -- The old saying that "what goes up must come down" doesn't apply to carbon dioxide pollution in the air, which just hit an unnerving milestone.

    Yeah, that is good news.

    The best thing about these ideas is the export markets. Any strong innovation will bring in jobs and dollars.

    Ironically, it is the right wing who seem most opposed to innovation, and most committed to coal and petrol.

    "Innovation" is what has driven hydrocarbon supplies for the last 100 years. The kind of innovation "the right wing" supports- not opposes.

    The left wing on the other hand opposes all things hydrocarbon. And at any cost.
    And to the extent of taxing and regulating hydrocarbon production while subsidizing renewables/alternatives. Market manipulation is hardly innovation.
