slowed.”
Potsdam scientists have already proposed that
human release of greenhouse gases – the con-
sequence of profligate use of fossil fuels – has
now lifted the Earth from its million-year cycle
of Ice Ages and interglacials into a new stabi-
lised state, known variously as the Anthropo-
cene and “the Deglacial.” And Stockholm sci-
entists have joined them in warning that there
are more uncertainties and climate stresses to
come. And, the authors warn, the impact on human
society would be “massive, sometimes abrupt
and undoubtedly disruptive.”
Planetary threshold
The new study however re-examines the pos-
sibilities and once again spells out the dangers
in language of uncompromising clarity. “The
Earth system may be approaching a planetary
threshold that could lock in a continuing rapid
pathway toward much hotter conditions – Hot-
house Earth.
“This pathway would be propelled by strong,
intrinsic, biogeophysical feedbacks difficult to
influence by human actions, a pathway that
But, of course, nobody knows at what point
such a dangerous slide into a new tempera-
ture zone could become inexorable, and the
researchers make this clear.
“What we do not know is whether the climate
system can be safely ‘parked’ near 2°C above
preindustrial levels, as the Paris Agreement
envisages,” said Professor Schellnhuber, “or if
it will, once pushed so far, slip down the slope
towards a hothouse planet. Research must
assess this risk as soon as possible.”

EASY ORGANICS
by Talborne
• Use organic growing methods to recapture
environmental health.
• Harsh growing methods have created dead
and lifeless soils as natures process were
neglected and replaced with synthetic
quick fixes such as water soluble salt
based fertilizers and toxic poisons for pest
and disease control.
The organic philosophy is healthy soils grow
healthy plants.
So use the following time tested organic
methods to build optimum soil quality:
1.
•
•
•
MULCH
Prevents water loss and soil erosion,
Suppresses weeds
Keeps soil temperatures constant.
USE THESE AS MULCH:
Leaf mould made from your produce offcuts,
trees and garden
bark or exotic trees wood chips, pebbles or
stones, or nut shells.
If you prefer use live mulch such as, green
manures, groundcovers, legumes, seedlings.
2.
COMPOST
It is essential in the organic farm.
• It retains moisture,
• Builds good soil structure,
• Aerates soil, and
• Feeds earthworms and microbial soil life.
This beneficial soil life returns the favour
by protecting plants from disease-causing
pathogens, tilling the soil and converting
compost to humus and minerals to plant
food.
• All these processes are vital for healthy
plant growth.
SOURCES OF COMPOST:
Convert trimmings from packhouse, garden
and household waste into compost.
Use mulch of straw, animal bedding, pruning,
