Oops! Rising CO2 proves beneficial to ‘greening’ Earth

earth greeningFor those who have staked their professional reputations on man-induced “climate change” being “settled science,” a new study that confirms rising CO2 levels are driving the “greening” of the planet could be unsettling.

Instead of the western U.S. becoming more arid and brown, as predicted by climate models that assume catastrophic man-made global warming, examination of decades worth of satellite data reveal significant increases in vegetation growth. Indeed, this greening was observed over 25 percent to 50 percent of the vegetated areas of the Earth’s surface, based on analysis of 28-years worth of satellite imagery. The increased biomas serves as a sink, or temporary storage site, for increased CO2.

The study, conducted by an international team of 32 researchers from 24 institutions – representing nine different countries (Australia, China, France, Germany, Japan, Spain, Switzerland, the United States and the United Kingdom) – used satellite data from NASA’s Moderate Resolution Imaging Spectrometer and the National Oceanic and Atmospheric Administration’s Advanced Very High Resolution Radiometer instruments to help determine the leaf-area index, or amount of leaf cover, over the planet’s vegetated regions.

Approximately 32 percent of the Earth’s surface – oceans, lands and permanent ice sheets combined – is covered by leaf growth. Those leaves use energy from sunlight through photosynthesis to chemically combine CO2 taken from the air with water and soil nutrients to produce biomass, making the much-maligned greenhouse gas a plant fertilizer.

Contrary to model predictions, the satellite data showed increases in vegetation growth on up to 50 percent of previously vegetated areas, with a decrease in only 4 percent. The Earth’s increased greening was equivalent to expanding the planet’s vegetation coverage to an area twice the size of the continental U.S.

    But the BBC cant resist their bit of climate alarmism:
    ‘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.’

    See!!! We’re all doomed!!! 😉

    The first time I ever said anything sceptical about the climate it was “but there’s been no warming over the last 5 years”. I thought the response would be a quick … but if you look over X years … it is warming …. and that would be the end of the comment.

    But it wasn’t. It was as if I had suggested the person dine with Saton. They were incapable of handling it. They couldn’t calculate the trend themselves – they couldn’t formulate their own argument even though in their position I could so easily dismiss it.

    Likewise, the fact that plants need CO2 is obvious to anyone who has ever done any biology. So, it is absolutely no surprise that CO2 is good for plants. So, I nearly ignored this story as the GWPF had come out with almost exactly the same research. “Nothing new” as far as I was concerned.

    But I forgot that alarmists just can’t handle these contrary facts. Their views are based on belief and what they can copy n’paste from alarmists websites. And they rely on their slogans like “CO2 is a pollutant” to persuade the dim-witted gullible people who swallow their alarm.

    So they desperately need CO2 to be killing plants – and in turn animals. Because take away the “immorality” of CO2 and they have nothing. And it’s not helped by the lack of warming, that no adverse trend in severe weather, no melting Antarctic ice – Greenland surface ice growing etc.

    All they really had left a few activist journalists who would print any drivel they were given, bogus surface data from the likes of NOAA and NASA and this idea that in some way CO2 was a pollutant.

    Now they don’t even have that. And the research was not from someone like the GWPF – but from one of their own number who made it clear it was not something they liked publishing.

    It’ll be like spraying them with systemic weedkiller – they’ll look fine for a while, but it will gnaw at them inside.

    A Greening Earth … The Horror .
    This is not good news for the big media
    propaganda mission on scary global warming .
    In fact it will be ignored and they will pretend it doesn’t exist . Let’s simplify .
    Greenhouses add more CO2 to make plants grow . The earth is greening because us nasty humans (or maggots as David Suzuki likes to get off thinking of us as ) are putting a whole fraction of 1 percent more Co2 into the atmosphere to add to this earth beautification.
    Surprise, surprise it’s getting greener .

    When did the scary global warming promoters
    know this and why did they not share this good news ? Were they trying to promote their
    shareholder interests ? Pump up the tires on tax payer subsidy renewable charity companies ? If AG lobbyists have so much time on their hands those are the pump and dump promoters that need to be investigated .
