    Elizabeth Kolbert, on Democracy Now! 2/11/14:

    This writer seems to know a good, sciencey subject:


    http://www.democracynow.org/2014/2/1...eth_kolbert_on


    In the history of the planet, there have been five known mass extinction events.


    The last came 65 million years ago, when an asteroid about half the size of Manhattan collided with the earth, wiping out the dinosaurs and bringing the Cretaceous period to an end.


    Scientists way we are now experiencing the sixth extinction, with up to 50 percent of all living species in danger of disappearing by the end of the century. But unlike previous extinctions, the direct cause this time is us — human-driven climate change.


    In "The Sixth Extinction: An Unnatural History," journalist Elizabeth Kolbert visits four continents to document the massive "die-offs" that came millions of years ago and those now unfolding before our eyes.


    Kolbert explores how human activity — fossil fuel consumption, ocean acidification, pollution, deforestation, forced migration — threatens life forms of all kinds.


    "It is estimated that one-third of all reef-building corals, a third of all fresh-water mollusks, a third of sharks and rays, a quarter of all mammals, a fifth of all reptiles, and a sixth of all birds are headed toward oblivion," Kolbert writes. "The losses are occurring all over: in the South Pacific and in the North Atlantic, in the Arctic and the Sahel, in lakes and on islands, on mountaintops and in valleys."

    Hey, now. I wonder, if the tea-bag derps can read any of this, before the lights go out?


    Tell me, what'd I say . . .

And that's just the way it is." -Terrible Ted from Texas "Obama has an affinity, for inciting the neo-con zombies, into an eternal loop, of destructive, multi-media gridlock." -OK, I said that one . . .

    You are such a whiz on history, what do you think happens when any nation continues to spend more than they take in?
    What do you think the core of the tea party is?

    And as to the CO2 level, take a wag at the greatest impetus on increasing it. Do you even know?

    Calling all derps! Basic science information is here . . .

    The idea that mass extinctions happened, without humans is not relevant, since humans are present, and humans are causing M.E.E.6, not only by instigating climate change-related extinctions, but by introducing and wiping out species and habitats.

    If American internet mavens burn enough bandwidth, with denial adverts, liability issues may crop up, in some ICC or civil action, soon!

    It seems some of the people clowning around are connected, to peTROLLeum companies, you see!
    One way humans issue too much CO2 is corrupt and stupid persons waste media.

    Another way is humans destroy CO2 degradation and respiration, so over time, any CO2 should degrade, but this will NOT, since it tends, to be absorbed, by oceans, which are becoming saturated and more acidic, but any absorbed CO2 is compensated, by emitted CO2.

    Hey, when you fire stuff up AND burn stuff down AND poison, humans have current CO2 AND warming AND climate change AND extinctions, as an anthropogenic responsibility.

    As for which humans waste the most media, to be a CO2 and any other kind of nuisance, that is obviously posses, of neo-con gits.

    Well, we certainly can't ban humans. Then we couldn't fleece them for money to fix the "crisis".

    Question

    Is Katla gettin' ready to erupt?...

    Iceland's Katla volcano hit by unusually large earthquakes
    Tuesday 30th August, 2016: Two unusually large earthquakes hit one of Iceland's biggest volcanoes early on Monday, raising concerns of a possible eruption, the Icelandic Met Office said.
    The Katla volcano has not erupted properly since 1918 and scientists say it is overdue to do so, although an eruption could still be decades away. "It is quite a dynamic situation now, in the next hours and days following this, but as we speak at the moment we do not see any signs that there is an imminent hazardous unrest about to happen," Matthew Roberts, a natural hazards scientist at the Icelandic Met Office, said.

    Ash from an eruption of the nearby Eyjafjallajokull volcano in 2010 shut down much of Europe's airspace for six days. Katla, in southern Iceland, was rocked by quakes of magnitude 4.5 and 4.6 overnight. The volcano sustained similar movements in 2011.

    The volcano is covered by an ice cap, which should, in the event of an eruption, typically contain the lava for around 60 to 90 minutes, giving time to alert the population and international air traffic, Roberts said.
