Tipping Into a Hostile Planet

In an era of affordable and reliable chainsaws, researchers are telling us that we only
have a couple of decades to reverse Climate Change if we are to avoid “tipping” into a
“hostile” planet of ever increasing weather extremes, with all that goes along with it.
Several tipping factors are described, any one of which could cause others to
tip in a “domino” effect. One of which being Ocean acidification and subsequent
decline of floral plankton, the planet's lungs, the result of CO2 absorption.

The solution offered here would consist of laying a carpet of evergreen bushes, eg,
Rhododendrons, etc. at the very centre of the world's major deserts, letting them
spread prolifically whilst supporting biodiversity - the bottom end of the food change.

The principal problem is irrigation/desalination.  The power needed to purify, pipe
and pump water over these enormous distances could initially come from Renewable Energy
Sources. Later, Thorium Molten Salt Reactors (LFTR) will become available. The costs
would be less than a Mars colony or a couple or few Navy carrier fleets. Particularly
since the US army had already installed a nuclear power plant under the ice sheet in
Greenland in the 1960's - in total secrecy, with a Navy NPP on the Antartic under
an aluminium dome, to a fanfare of publicity.

The bonus of fertile, high-value real-estate at a time of rising sea level would offset
the initial investment.
