'Funny weather we are having' is a statment  of  the  obvious  we have used for generations as a greeting. When the deep cold lasts long and heavy snow and blizzards give us the shivers we  replace "funny" with something stronger, such as  "terrible",  "ghastly". At times like these people ask what is happening to the  weather. So we go to the experts, who tells us, in language appropriate to the subject, what happened yesterday, what  is  happening  today, and what might happen in the next few years. Weather and  climate specialists all over the world have ammassed a  vast  quanity  of information. They can describe what is happening around us.  With satellites they can forecast more accurately what might happen in the immediate future. Their research has produced evidence of why past climatic changes took place.
There have been many climate fluctuations  ovver  th  10,000 years since Britain was last covered with an ice sheet.  Advances and retreats of ice in the northern hemisphere  during  the  past 500,000 years can be accounted for by changes in the warmth  from the Sun.
This was caused by  alterations  in  the  Earth's  orbit  at periods of 96,000, 40,000 and 20,000 years.
Although that  theory  is  widley  accepted  as  a  possible explanations for ice ages, it has not been proved. More  than  50 theories have been put forward, but only  a  few  have  not  been completely dismissed.
Not long ago a new  theory  was  published  in  the  science journal "Nature". According to  Dr.  Garry  Hunt,  of  University College, intense radiations  from  the  nuclear  explosion  of  a nearby supernova - a star - could cause the destruction  of  part or all of the ozone layer and in this way trigger an ice age.
As for me, i like  Autumn  best  of  all.  The  days  become shorter and the nights longer. It isn't so hot in  the  day-time. The trees are covered with yellow and red leaves. At the  end  of summer apples, pears, plums and other fruit become ripe.  In  the South there are many oranges, peaches and tangerines.  Autumn  is plesant when it does not rain. General Autumn is a  rainy  season of the year. When it rains the  weather  is  nasty.  The  sky  is covered with heavy clouds. It drizzles. It is muddy and wet.
