We discuss and comment on the role agriculture will play in the containment of the CO2 problem and address protocols for terraforming the planet Earth.
A model farm template is imagined as the central methodology. A broad range of timely science news and other topics of interest are commented on.

Comet ISON Lives
We still do not know
how much but it appears we can count on a mass of debris at least and
presumably a large dust cloud unless the magnetic field somehow stripped it all
away. However that is not the pattern for
comets unless close in is a limiting factor.
We still got an
intriguing show going in with a lot to think about.
Now we will see what
the aftermath can produce for show and tell.

possibly creating a brilliant tail.

There was the possibility, of course, that ISON is just was just its death
there was some speculation that what had come out the other side was just dust
from the comet being torn apart. But as the hours passed, it became
increasingly evident that what remained — though much smaller — was more than

since its emergence.
a comet passes through our solar system, the sun’s heat and solar wind causes
frozen material to turn into gases in a process called sublimation, creating
the tails of comets that we see.
closer a comet gets to the sun, the more heat, thus more sublimation.

approach on Thursday.

that’s just what astronomers had thought had happened.
ISON made its closest approach at 1:45 p.m. EST, it had lost its nucleus, or
core. Many surmised that this signalled the end of the comet. Hope of its
images of ISON don’t show a distinctive nucleus, so it’s likely that it is
merely a fragment of the two-kilometre wide comet that had approached the sun.
around the world will continue to monitor the progress of ISON to see if it
regains its brightness, though it’s likely that it will become dimmer or just
fade from view entirely.
if it continues to brighten, it will be visible in the early morning hours near
the horizon within the next couple of days.
