sahara desert SHRINKing

facts: now in year 2018 the AREA of sahara desert is 9.2 million square kilometers which is more than the area of australia 7.6 msk.
what was the area in previous decades?
in 1984 its area was 9.982 million km^2 larger than china, so we see a long term trend of shrinking altho it probably swells and shrinks each decade the fact is in the LONG TERM  long term we see a trend of shrinking to smaller than china.
this is supported by the report in 2012 when the sahara was "3.6 million square miles (9.4 million square kilometers)" we see that from 1980's to 2012 shrinking by almost 600,000 square kilometers and continued shrinking since then 2012 until now by a further 200,000 square kilometers.
last year 2017 was a surprising snow in the sahara in the country algeria so water was moved to the sahara.
i recall in the 1980s when people first panicked about FLOODING they were buzzing about the tragedy of global warming.... america would be covered in water floods... yet we must consider facts
we know hot things expand and cold contracts well consider the temperature of the ocean on coast of west america is in april the same as in the winter 50 degrees f. as glaciers move ice into the ocean it cools the ocean so the water will contract and NOT FLOOD the coasts.
water is being moved to antarctica which has  experienced in the last few years INCREASED snowfall... consider the arabian desert is ARID around 10 cm of rainfall in contrast to antarctica more 16.6 cm and NOT ARID  not dry so not a true desert because more rainfall as snow and not dry.
as water moves to poles and sahara less fear of flooding oceans and glacires "calving" means ICE moves into water cooling... you can all see the pictures of glaciers  i ask are they "melted water"? certainly not the ice cools the ocean contract the volume so no fear of flooding and water to sahara less chance of flooding and in fact the long term is sahara desert has been shrinking we can project that in 40 more years the sahara will be 9.2-0.8 msk smaller around 8.6 msk or the shrinking could accelaerate as we saw rare snow in salgeria last year... if the governments of mali and mauritania and libya would work together they could actively shrink the sahara desdrt and change its edges into land to grow food crops algeria now grows only 1% trees and almost all desert and "dry" or dryer... unemployment there is high in 2000 at 30%.
 only 75 thousand sk fields in a vast country 2.3 msk. for over 30 million people thery could be shrinking the desert and adding fields for wheat but that is not a priority for a religious government sunni musklims fast ramadan so a month of less eating means ...
also libya is almost all arid desert  barely 0.2% trees.
only the coast has rain for whea from a total of 1.8 msk. this seems reckless and bad pririties but the priority of a muslim government is to enforce islam not to feed the populkace.
similar mali and chad almost all desert except near rivers... could fight desert... and arabian desert second largest desert in world probably these countries import most food for example saudi arabia
