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.

Planet X Evidence Clarified
The idea of
an additional large planet orbiting far outside our solar system has been
around for a long time.It may well
exist.It may even be a brown dwarf that
we simply can not see.
think that a circular orbit is unlikely.Sitchen predicted his plane X to have a long elliptical orbit that
brought the planet into the inner solar system.
We have even
better evidence that we orbit through the Sirius cluster every 200,000 years or
so.Such an event could well look like
planet orbiting us.
likely produce a distorted orbit for a distant solar planet.
have learned that disturbing a comet is not an easy trick without a big object
and that the presence of comets is confirmation of perturbation.Something(s) is out there.Yet perturbed orbits could still be artifacts
of the pass through Sirius over a 100 thousand years ago.
There may be
room for everything, but if we give credence to any of the material, I find the
pass through Sirius satisfying because it gives us a large hot object that
could meet the requirements of purported eye witness reports that Sitchen
presently no obvious evidence of any recent comet disturbances which suggests
that any hypothetical planet is a long ways away for now.

Scientists believe that an object with a huge mass may be pushing comets
towards Earth from the cloud
calculations suggest a large object that is up to four times as big as Jupiter
could be responsible for sending them in our direction.
scientists have analysed the comets in the Oort cloud and deduced that 25
per-cent of them would need a nudge by a body of at least Jupiter size before
they changed orbit.
John Matese and Daniel Whitmire at the University of Louisiana
came up with theory said that 'something smaller than a Jovian mass would not
be strong enough to perform the task'.
believe that our solar system has a hidden 'companion' that has so far remained
scientists have been studying the cloud using WISE, Nasa's infra-red space
telescope that is capable of detecting dark objects.
said: 'I think this whole issue will be resolved in the next five to 10 years,
because there’s surveys coming on line that will dwarf the comet sample we have
these types of asymmetries in the directions that comets are coming from

Matese added. 'We anticipate that WISE is going to falsify or verify our
3,200 long-period comets are known, one of the most famous being Hale-Bopp
which was visible to even the naked eye during 1996 and 1997.
Comet, which reappears about every 75 years, is a 'short-period' comet from a
different part of the Solar System called the Kuiper Belt.

suggest that during its orbit it would regularly enter the Oort cloud, jostling
the orbits of many comets there and causing some to fall toward Earth.
occasional comet showers could be why the mass extinctions on Earth are so
regular, some scientists believe.
research appeared in the online edition of the journal Icarus.
planetary scientists would not be surprised if the largest undiscovered
companion was Neptune-sized or smaller, but a Jupiter-mass object would be a
surprise,' Matese told SPACE.com
conjecture is indeed true, the important implications would relate to how it
got there — touching on the early solar environment — and how it might have
affected the subsequent distributions of comets and, to a lesser extent, the
