Climate science is a multi-disciplinary science covering especially geology, biology, chemical and physical oceanography, astronomy and all the other physical sciences and designating water, agriculture, aquaculture and energy policies of a country.
Climates are the natural phenomena continuouslyvarying in periods ranging from decades to millions of years and thus effecting and controlling especially the water, aquaculture and agriculture of the world. Basic reasons of such variations are plate motions, parameters of the rotation of the earth and variation in solar energy coming from the sun. All these events result in variations in climates in either short or long periods, periods of dry and wet cycles.The shortest of those cycles is around 20-22 years. Of this cycle, about 7-10 years is wet (over the regional averages) and 7-10 years is dry (below the regional averages) (Van Oldenbor.J.AndG.Burgers, 2005).
In climate science, global warming periods are called “pluvial-age” and global cooling periods are called “ice-age”. In other words, global warming periods are welfare periods with higher precipitations and consequently higher “productivities”. Global cooling periods on the other hand are “famine” periods with lower temperatures and consequent lower precipitations.
Since world population increases 100% in every 45 years, cooling periods, “famine periods” create more problems for humanity.
And the world is moving toward a severe cool down period expected after the year 2020, in other words to a period with fewer precipitations, less agricultural and aquaculture productions, adverse impacts on energy sector. And, entire developed countries are making preparations for such a period.
İzmir should meticulously be prepared for this “mini-glacier” period expected after the year 2020 and the agricultural and aquaculture policies of the water-poor region should urgently be rearranged.
Today, global warming, started after major global cooling (glacial period) 18 000 years ego, is still on-going even with intermittent very severe “mini glacial periods”.
The period expected after the year 2020 is also such a severe mini glacier period.In other words, science world unanimous that temperatures will decrease and therefore precipitations will also decrease and consequently severe drought period will emerge.
