Increased CO2 Leads To Greening Of The World

Planet Earth is on a roll! GPP is way up. NPP is way up. To the surprise of those who have been bearish on the planet, the data shows global production has been steadily climbing to record levels, ones not seen since these measurements began.

GPP is Gross Primary Production, a measure of the daily output of the global biosphere –the amount of new plant matter on land. NPP is Net Primary Production, an annual tally of the globe’s production. Biomass is booming. The planet is the greenest it’s been in decades, perhaps in centuries.

They found that over a period of almost two decades, the Earth as a whole became more bountiful by a whopping 6.2%. About 25% of the Earth’s vegetated landmass — almost 110 million square kilometres — enjoyed significant increases and only 7% showed significant declines.

Plants take the carbon from CO2 to bulk themselves up — carbon is the building block of life — and release the oxygen, which along with the plants, then sustain animal life. As summarized in a report last month, released along with a petition signed by 32,000 U. S. scientists who vouched for the benefits of CO2: “Higher CO2 enables plants to grow faster and larger and to live in drier climates. Plants provide food for animals, which are thereby also enhanced. The extent and diversity of plant and animal life have both increased substantially during the past half-century.”

From the 2004 abstract: Our results indicate that global changes in climate have eased several critical climatic constraints to plant growth, such that net primary production increased 6% (3.4 petagrams of carbon over 18 years) globally. The largest increase was in tropical ecosystems. Amazon rain forests accounted for 42% of the global increase in net primary production, owing mainly to decreased cloud cover and the resulting increase in solar radiation.

Doubling the jeopardy for Earth is man. Unlike the many scientists who welcome CO2 for its benefits, many other scientists and most governments believe carbon dioxide to be a dangerous pollutant that must be removed from the atmosphere at all costs. Governments around the world are now enacting massive programs in an effort to remove as much as 80% of the carbon dioxide emissions from the atmosphere.(...)
If these governments are right, they will have done us all a service. If they are wrong, the service could be all ill, with food production dropping world wide, and the countless ecological niches on which living creatures depend stressed.

Amazingly, although the risks of action are arguably at least as real as the risks of inaction, Canada and other countries are rushing into Earth-altering carbon schemes with nary a doubt. Environmentalists, who ordinarily would demand a full-fledged environmental assessment before a highway or a power plant can be built, are silent on the need to question proponents or examine alternatives.

Earth is on a roll. Governments are too. We will know soon enough if we’re rolled off a cliff.

Both Michelle Malkin Blog and Watts Up With That? linked to an article by Lawrence Solomon at the Financial Times. Watts Up included a link to a fascinating set of NASA images showing that increase in growth.

Let me reiterate what I have said before;

We really don't yet know what we are doing and we run the risk of destroying the basic structure of our civilization with many related deaths. If we can't manage to destroy a bacteria effectively how do we think we can destroy something as complex as the ecosystem.
